Pressure Testing: Purpose, Regulation Requirements and Its Risk Factors

Pressure Testing has a great importance among industrial processes, as it is a non-destructive test that verifies the system’s integrity of pressure shell on new or old installed tools and equipment; this mechanism also has the ability to detect tightness of a system against leakage.

Pressure Testing has equally importance in the fabrication process, and it is a last physical quality test that performs in a controlled environment. Most of the piping codes require this test, to ensure that repaired or a new piping system is capable to maintain its safety against rated pressure and leakage. 

Most of the regulatory and enforcement agencies compliance to piping codes that mandates for the construction of the system. Nowadays, Pressure testing is mainly preferred due to good safety considerations, whether Pressure Testing is legally backed or not, it serves constructively by protecting works and public.

Pressure Testing establishes a pressure rating for required components. It may also be used to establish a safe rating by calculating various special systems. Before start-up of new systems, Pressure Testing is performed to confirm the integrity of vessels and to obtain relevant certification.

Regulation Requirements for Pressure Test

Pressure Testing is also demanded by the regulation requirements. The important points of these regulation requirements are given below:

• By using the hydrostatic method, all the pressure piping leak tests must be conducted.
• A pressure piping system will not test at a temperature that is colder than its minimum allowed temperature.
• When conducting a Pressure Test, a contractor must considered the ductile-to-brittle transition temperature and the possibility of brittle fracture.

The biggest advantage of Pressure Testing is that it can be performed at low working pressure. The fatal disadvantage of pressure testing, exposure to aged equipment with poor toughness could result in the brittle fracture.

From the above discussion, it can be concluded that the pressure test procedure confirms safety. The purpose of such procedure is to ensure pressure tests are conducted safely and effectively. They apply to mechanics, supervisors, inspectors and subcontractors responsible for pressure tests. Pressure tests are performed to verify the reliability, and leak tightness of pressure systems. A pressure test is required for a new pressure system before use or an existing pressure system after repair or alteration.

A general overview to Pressure Vessel and its Components

What is a Pressure Vessel?

A Pressure Vessel is a closed container that holds liquids and gases, in which pressure is builds by the application of heat from an indirect or direct source, a direct or indirect source of heat builds the pressure in the chamber. It is designed in such a way that pressure at which it holds liquids or gases is different from the surrounding pressure. Difference in pressure can be very dangerous, as it is evident from history that pressure vessel development and operation caused many fatal accidents.

Components of the pressure Vessel

The components of the pressures vessels are as follows:

• Shell
• Head
• Nozzle
• Support

Shell: Shell is the primary component of the pressure vessel, which contains pressure. Shell of pressure vessel is in the form of different plates, welded together to form a specific structure that has common rotational axis. In most of the vessels, the shell is a component that provides the longitudinal length of the vessel. The thickness of the shell based on the pressure and on any additional loads that created by the supports, nozzles and other attachments. Shells are available in cylindrical, spherical or canonical in the shape. Most of the shells have circular shapes, so due to their circular form the equal distribution of forces applies on it.  Horizontal drums have cylindrical shells and constructed in a wide range of diameter and length.

Head: Head is another component of the pressure vessel. All pressure vessels must be closed at the ends by another shell section or by head. Heads are made in the shape of curved rather than flat because the curved configuration of head is stronger, which allows the heads to be thinner, lighter and less expensive than the flat heads. When heads are used inside a pressure vessel, then they are known as “intermediate heads”. These intermediate heads are separate sections of the pressure vessels that permit different design conditions.

Nozzles: Nozzles are also one of the major components of pressure vessel that has insertion in the shell, which later connects to the process pipe. Depending on the design of nozzles, they can also connect to flanges or threaded fitting. Depending on the following given factors manufactures design nozzles:

• Manufactures must consider the metallurgy of the shell and nozzle.
• They must checks the internal and external projections of the nozzle.
• Before designing, they must consider the orientation of nozzle & internal and external forces that acts on the nozzle, such as pressure and piping forces.

Supports:  Support is also a component of pressure vessel that can be used to bear all the loads like, earthquake and wind loads. Depending upon the orientation and size of the pressure vessel, different types of supports are available in market. The design of this component deals with external forces (wind forces and seismic zones) and physical dimensions of the vessel such as weight, length etc.

What are the Advantages of Pressure Vessel?

Pressure vessel has the following given uses in different manufacturing industries:

• Pressure vessels are used in different industries like Petroleum refining, Chemical, Power, Food & beverage and Pharmaceutical.
• They can be used as storage of high-pressure gas, gas scrubbers, two and three phase separators and some other functions.
• They can be used in different types of boilers such as steam boilers etc.

Inspection Overview Of Pressure Vessel

Simply, a pressure vessel appears as a storage container, fabricated to accumulate pressure more than 15 p.s.i.g. In several inspections of pressure vessels at workplaces, usually numerous cracks and damages are observed on their surface. Such cracks and damages on the surface of pressure vessel result in the form raptures & leakages, even they can be risky to health and safety measures in workplace due to air poisoning, suffocation, explosion and fire. In severe case, damages in vessel can result fatal and can bring harm to ecology and property assets. Therefore, to ensure safety & health of workers, the design, manufacture, operation and maintenance of pressure vessel should be according to designated procedures & standards.

Below, the techniques & technologies handy in pressure vessel repair after inspection, by preventing premature failure and shutdown of facility:

Inspection Techniques Of Pressure Vessel:
To ensure safe operation of pressure vessel, online inspection is in the benefit of plant processing as well as surrounding environment. To find out the thickness of vessel surface, ultrasonic testing is widely conducted over industrial level. The purpose of such testing is to check regularly the thickness of metal of suspected areas with necessary equipment, if thickness of surface reaches at minimum allowable limit, then precautionary measures should be taken in order to keep plant working.

Notably, the other inspection techniques incorporate designing & maintenance of pressure relief valves along with installation of corrosion coupons & sentinel holes.

Real Time Example:
A. J. Warner, a senior engineer, who works for a refinery plant in Texas, quotes an example "Consider, for example, that a key Gulf coast refinery develops a serious problem in a pressure vessel. This will likely cause a shutdown of that unit, lasting anywhere from one day to several weeks or longer. This causes a disruption or shortage in the supply of gasoline to the market, which will drive up the cost at the pump. Therefore, it is in the best interest of everyone that pressure vessel technology remains a key focus area for the refining industry and beyond."

Keeping it in same way, Millennium Industries, a pressure vessel manufacturer at industrial scale maintains health and safety measures at its facility. Company aims to provide those industrial solutions, which have less affect over environment, impact over employees’ health, control risk factors and safe work practices.

Hydraulic Pumps

Hydraulic pump is a mechanical device which is used to converts the mechanical power of the system into hydraulic energy. To overcome the pressure which is induced by the load hydraulic pump generates high power flow.

A hydraulic pump performs basic two functions when it operates:

• A mechanical action which creates a vacuum at the pump inlet, it permits atmospheric pressure to force liquid from the reservoir into the inlet line to the pump.

• The second function which is performed its mechanical action that delivers liquid to the pump outlet and then forces it into the hydraulic system.

Why we need Hydraulic Pumps?

We need hydraulic pumps because they are the main sources of power for different dynamic machines. Hydraulic pumps have the power to push large amount of oil through the hydraulic motors and cylinders. In returns, the pump converts the mechanical work of energy into the hydro static energy.

Principle on which Hydraulic pumps operates

According to the displacement principle the hydraulic pump operates. In this principle the existed mechanically sealed chambers in the pump may involves. The purpose of these chambers is to transport the fluid from suction port (inlet) of the pump to the pressure port (outlet). These sealed chambers also ensure that no direct connection between the inlet and outlet port of the pump. This is the main reason that these pump suitable to operate at very high pressure and they are also ideal for Hydraulic systems. The mechanism of pump is shown in the figure below:

Mechanism of a pump

Types of Hydraulic Pumps

Depending on their different functional and other system requirements such as range of pressure or flow, operating medium, type of drive etc. hydraulic pumps are manufactured. Hydraulic pumps may have large range of design principle and configurations. All pumps can’t fully meet the requirements of the system. So for that reason different types of hydraulic pumps exists which are given below:

Hydraulic Gear Pumps

External gear pump

Internal gear pump

Gear ring pump

Screw spindle pump

Hydraulic Vane Pumps

Single chamber vane pump

Double chamber vane pump

Hydraulic Piston Pumps

Axial piston pump

Radial piston pump

Uses of Hydraulic Pumps

Hydraulic pumps are used in hydraulic machines. While selecting a hydraulic pump it must have good frequency, pressure and temperature capabilities. Hydraulic pumps are used to do different type of works such as open, close, lower and to lift components.They are also used in field services like machining and assortment of construction

A pump produces liquid flow or movement which is necessary for the development of pressure. This is a function of resistance to fluid flow in the system. For example, the pressure of the fluid at the pump outlet is zero for a pump not connected to a system (load). Further, to overcome the resistance of the load, pressure will rise to the level for a pump delivering into the system.

Welding Repair

Weld repair is a process in which remove the damages of a metal. Metal damages removes from the use of Oxy fuel welding and by using carbon arc gouging or plasma cutting. For a good metal weld repair we must follow the steps which are involves in weld repair process.

Welding Procedure

For the use of welders a logical procedure of welding is to be applicable. In this procedure use special metal fillers and preheat the metal. In most of the construction companies, we can successfully weld a steel metal by using the following three steps which are:

•  In first step, Cutting the metal into the parts and removed the defected Components.
• In second step, prepare the new metal weld joints
• In third step, welding and cleaning the metal.

Step 1: Cutting metal into the parts and removed the defected components.

In the first step of welding repair removes the damages of a metal. This step can complete with the use of different welding techniques. Plasma and oxy-fuel are used for cutting a metal. We can also use carbon arc gouging which is well suited for removes the cracks from metal without harming the other parts of a metal.

With the help of different tools we can repair a metal. One of the most commonly used for cutting a metal is Oxy-fuel torch. Another tool which is used for cutting a metal is plasma cutters. By using plasma cutters welders can cut small parts width of metals. Plasma cutters are faster than the Oxy-fuel torches because by using plasma cutter welders can also cut electrical conductive metals but with the use of oxy-fuel torch welders can’t cut the stainless steel or aluminum metals. One of the most other common tools is carbon arc gouging which is used for welding generators. In using a carbon arc gouging uses an electrode which is made up of a carbon. By using this electrode welder can remove the defected parts. In result high pressure stream of air will released.

Step 2: prepare the new metal weld joints.

In the second step, welder will choose the filler material and replace all the parts with selected material which is better and have more power strength of the previous original material. According to their different mechanical properties such as tensile strength, wear resistance and ductility etc they have different applications. For avoiding long term failure of welding must ensure the quality and remove the unwanted downtime defects. When you will choose the right alloy then cut the steel and bevel the edges. After this preheating is required this is to be done by the use of oxy fuel torch.

Step 3: Welding and cleaning the metal.

In the third and last process, welders choose the welding process which they will follow to weld a metal. There are two most commonly used processes are:

•            Shielded Metal Arc Welding (SMAW)
•            Flux Cored Arc Welding (FCAW).

This article is all about the welding repair process. Millenniumind industry will offer the all these services.

Fabrication classes

Fabrication classes

Metal fabrication shops includes many processes of producing metal elements by ever-changing the raw metal material exploitation varied tools. The processes are classified as cold, heat and hot operating betting on the temperature at that the fabric is processed. Most of the objects around USA like paper clips, computers, bolts, nails, automobile components, components used for instruments and machinery and myriad alternative merchandise are remodeled by metal fabrication processes like bending, punching, drilling, turning, grinding, threading etc. The factors influencing the method enclosed the kind of fabric being machined, the speed of production, the specified pure mathematics, and alternative physical needs of the half.

Fabrication is divided into the subsequent classes. 

Metal Forming:

• Bending: All through bending, the work piece is bent to make flanges, contours, curls, seams, corrugations and alternative geometries by means that of applying force through hydraulic, gas and electrical machines. 

Shearing
• Conventional shearing: cutting off could be a metal cutting method through that flat surfaces cut employing a scissors-like action, typically in straight lines.

• Turret Punching: Turret Punching creates shapes in sheet material by in turn punching a series of basic shapes. Edges are cut by the cutting off action of a punch and die.

Material Removal

• Sawing: Sawing could be a variety of cutting within which the cutting implement could be a blade that incorporates a series of teeth, with every tooth removing a tiny low quantity of fabric. Sawing is usually wont to form stuff to the approximate size of the half, before further processes. 

• Sound: Tapping produces internal threads within the work. This involves use of a tool with multiple cutting teeth.

• Boring: Boring produces circular internal profiles in hollow work or on a hole created by drilling or another method.

• Turning: Turning rotates the work concerning its axis whereas applying cutting tools to form a desired form.

• Drilling: Drilling produces holes in an exceedingly work employing a fluted cutting implement.

• Edge: Milling removes little chips employing a rotating cutter that moves in 3 axes. 

• Grinding: Grinding could be a chip removal method within which the cutting implement is associate abrasive grain wheel. Differing kinds of grinding embrace Surface grinding, Cylindrical grinding, Internal grinding and Center less grinding.

Advanced strategies

• Optical device cutting: Laser cutting involves focusing a beam of high density energy on the surface of the work. The beam evaporates parts of the work in an exceedingly controlled manner.

• Electro Discharge Machining: Electro discharge machining is predicated on erosion of metal by spark discharges. This method is used for machining associate material that is an electrical conductor. 

• Wire EDM: The wire EDM or Electro Discharge Machining produces half shapes by cutting a metal work piece with a endlessly moving wire by means that of fast, repetitive spark discharges.

This method is employed to chop skinny and thick metal and is commonly wont to create punches, tools and dies from laborious metals. 

• Water jet Cutting: during this method, the force of a water jet is employed to chop material. The water jet acts sort of a saw and cuts slim kerfs within the work. Most of metals, plastics, fabrics, wood merchandise, and rubber, building material, leather, brick and composite materials are cut exploitation the water jet method.

Pressure Vessel Repair Safety and Precautions

Pressure vessels create a huge and significant hazard to those that work around them. They can critically wounded and kill. For this cause, hazards must be minimized when treating with or working pressure systems.

It is officially the owner’s accountability to supply a secure functioning setting, even as every person from the designer to the installer, to the user and owner has responsibilities to achieve to stay the pressure vessel repair harmless.

Within the USA, pressure vessels meet ASME Boiler and Pressure Vessel Code (BPVC) standards (Section VIII, Division 1) to guarantee an extended, functional service life.

The ASME Boiler and Pressure Vessel Code (BPVC) groups regulations of safety — connecting just to pressure reliability — prevailing the design, fabrication, and inspection of boilers and pressure vessels, and nuclear power plant components while production. The purpose of the regulations is to offer a periphery for corrosion in service. Encroachment in design and material and the proof of experience are continually being added.

Pressure vessels are usually harmless, it's only when a deprived loom or negligent approach is taken that tribulations lean to happen. The chief grounds of incidents are as follows:

·         Deprived design or equipment

·         Deprived maintenance

·         Hazardous operational practices

·         Operator error

·         Meager training/management

·         Derisory repairs

The frequent line in all these belongings is human fault. With the accurate systems prepared the hazard can be compacted noticeably, and accidents prohibited.

Some of the focal customs to decrease menace are includes the following:

·         Providing safe and suitable equipment

·         Being aware of the operating conditions

·    Fitting suitable protective devices and ensuring they work correctly

·         Carrying out suitable maintenance

·         Making sure all staff are trained to a good appropriate standard

·         Having equipment involved examined regularly

·         Using safe working practices and procedures

Non-destructive testing can successfully complete some of these necessities (suitable continuation and examining equipment), which is why it is extensively worn to examine the clause of pressure vessels repairs across the USA.

Non-Destructive testing employs a range of techniques to check equipment lacking mortifying it in any way, or having to scratch or smash it apart, such as for lab testing. It utilizes principles such as radiography, magnetism, eddy currents and acoustics to gather information in a non-invasive approach.

LFET (Low Frequency Electromagnetic Technique) can be used to examine the wall plates, while current technique can be used for welds. Additional techniques frequently used are dye penetrant, magnetic particle and ultrasonic depending on the necessities of the check, plus the aptitude of the company performing the examination.

During usual testing, the state of pressure vessels can be observed, and tribulations can be vetoed previous to they crop up. The outlay of check is always insignificant in perception, compared to costs earned after a foremost breakdown has occurred.

5 Myths about selecting Contract Manufacturing Companies

With much of today’s machines manufacturing outsourced, we wind up spending plenty of time within different contract manufacturing companies.

There are numerous reasons why we expend a lot of time in outsourced manufacturing services.

Here we are discussing the top 10 myths about selecting a contract manufacturing companies.

For an OEM that makes its existing advertising a physical creation, the assortment of a contract manufacturer to make that result is a substantial verdict. Nonetheless there are so many mistaken beliefs and lost concept about what is actually significant in the assortment criteria. The following is a list of some of the most common myths and misconceptions we see held by OEMs about selecting the right contract manufacturer.

1) “If I select the proper CM partner the whole thing will be perfect.” CM is a tricky, viable, low-margin business – and it is one that wants to be energetically organized. OEMs that get the good fallout, and that state the maximum rank of pleasure with their CMs, are ones that make up their personal actions association to efficiently run outsourced manufacturing.

2) “I just want to discover the lowest quote price.” For several products and markets, the X-works per unit manufactured quote price confines just 70% to 80% of the whole deliver chain expenditure I’ve seen many examples where departing with a per unit quote price that was 2 points inferior finished up costing an extra 5 points in other less noticeable costs – both interior and exterior. In addition, numerous CMs have strong and institutionalized business method for recognizing and detain extra costs that were not incorporated in the quote that are then approved on to the OEM in the structure of different fees and charges.

3) “My board will be overwhelmed if I sign on with a “Tier 1” manufacturing service provider.” The common rule of alliance CM’s into a variety of levels, usually from one to four, was urbanized by the financial markets in order to assist elucidate dissimilarities in survey multiples crosswise the industry. If we proxy the words “great big” for the words “tier 1” in the original quote above, the declaration lean to hum a bit more reliable with how childish it really is. The merely time an OEM really wants an immense CM is when they have a huge big piece of business to lay. In mainly cases we sponsor selecting the right size fit, additionally to considerate the fit across other extent counting technology, geography, management style/culture, end market experience and, of course, business model.

4) “I don’t want to be at a CM that is building for my competitor.” Why not? Is it because of the proprietary scenery of the built-up procedures that you are outsourcing to the lowest bidder? Rarely the sight supported in this citation is right, but in common it is mislaid and more times than not precisely mistaken. OEMs should locate the most generally proficient and companionable CMs for their precise business and often times this means structuring with the same company as one of your competitors – which is just not the same as running your product down the same line using the same support staff.

5) “I need a partner that is willing to invest in my business.”  In my knowledge, the statement above usually entails that the OEM is looking for someone to drop money building products for them. Infrequently is there a real benefit to having a key dealer mislay money on your account – and if you resume item number 2 aforementioned, the fact of the matter is that they rarely do. Expecting a CM with a 6% ROA and a 12% WACC to “invest” in your business is a bit like asking Bernie to manage your accounts.

ASME U Stamp Companies

ASME U Stamp Companies

The ASME which stands for American Society of Mechanical Engineers Certification Mark, which is observed as the trademark of acceptance and certification, is worn to signify that the stamped item(s) kowtow to the ASME Boiler and Pressure Vessel Codes (BPVCs).

Fuel Scrubber Manufacturer

Fuel Scrubber Manufacturer

A Fuel Scrubber is intended to decontaminate a cloud of gases earlier than it is unconfined into the surroundings. Noxious waste is detached from the cloud, letting for the escaping of nontoxic compounds whereas the risky ones are rapt for seizure and dumping. Fuel Scrubbers are necessary by law in environment where mankind effort with potentially polluting gases, and there are numerous designs obtainable for a variety of claims.

Another type of Fuel scrubber is a wet scrubber, where a liquid, usually water, is commenced into the ventilation hoard. The liquid is normally sprayed, or aerosolized. It ambush particulates in the gas and respond with compounds in the gas, moving them down to the base of the hoard. The liquid pools for storage, at which point it can be sprint through a wastewater handling plant and recycle or else progress to direct the toxins. It is universal to observe a noticeable trail when a wet scrubber is used, as some dampness is fashioned.

In a dry fuel scrubber, an amalgam is pioneered in the structure of a gas or powder. The amalgam adheres to firm molecules in the evading gases; ambushing them so they cannot be unconfined into the air. It is intended to descend or be ecstatic through illicit escaping, sanitizing the gases as they augment through the heap. The trail in this scenario may not be noticeable when it rises from the heap, as particulates should be detached and moisture levels remains firm.

Fuel Scrubber manufacturer systems normally need to be deliberate for precise applications, bearing in mind the nature of pollutants occupied and the quantity of fabrication. The scrubber must be planned to manage with peak loads exclusive of failing, as a blackout of the heap could be enormously pricey and, in some scenarios, hazardous. Scrubbers may also be built-in with filters and further devices, beside with air quality monitoring systems for the principle of confirming that they are working appropriately by diminishing dangers from the air and releasing only hygienic air into the setting.

Mounting clampdowns on allowable fumes in many areas of the world have required firms to be original about fumes control. Fuel scrubber design is continually under development as people labor on new systems for pulling out impurities in the air. convention are frequently planned to endorse development through enticement or the organization of deadlines for firms to gather new air class standards with fuel scrubbers manufacturer and other anti-pollution dealings.

Attributes of good Pressure Vessel Repair

Pressure Vessel Repair

An elevated pressure vessel repair is one that contains liquids or gases at pressure levels that are significantly diverse from the ambient pressure levels. This closed compromised are required to be fabricated by means of the highest engineering knowledge since the nominal fault could origin deadly consequences. These units play a fundamental job in the industrial sector nowadays. A pressure vessel fabricator thus requires to be authoritatively certified as one.

Did you know that they first came into exercise in Great Britain at some stage in the industrial rebellion? They were engaged as boilers to generate steam for powering steam engines and they played a key position in avoiding the probability of bang.

Currently, they are in use of geothermal plants, in food and beverages sector, in ships, nuclear reactors, mining sites, oil and gas refineries and many more.

They bear a number of liquefied gases for instance ammonia, LPG, LNG, CNG, butane, propane, chlorine and many more. In verity, they are also helpful in carrying heated water that is beneficial for the commercial and industrial purposes.

Pressure vessels repair are serious in numerous unusual applications for example in steam separators, in reactors, and fractionation towers.

As a consequence, it is vital to go over the significance of selecting a proficient pressure vessel repair:

It is necessary that the company is enlisted in ASME U Stamp companies. The firms that carry stamps of U, U2, U3, S and PP are critical; hence they contain the capabilities to credit your personalized as well as customary requirements.

These codes are not just partial to developed. Remember, to ensure if the company holds the National Board R-Repair Stamp, as this will facilitate you employ the services of the same company for outlook continuance and repair. It is for all time prudent to employ the unique producer for repair and continuance.

There are sure companies that have the power to verify gear in agreement with the European Pressure Equipment Directive. They also hold the certification to stamp equipment with the CE stamp.

It is always wise to associate with a firm that is more than just a pressure vessel fabricator. It also requisite to bring out process such as the manufacture of autoclaves, heat exchangers, cryogenic vessels, separators, reactors, vacuum chambers, weld overlay and clad vessels.

Always remember to verify the test services of your selected pressure vessel fabricator. It is necessary to confirm the presentation of each developed unit. Therefore, it is necessary that the selected company hold out newest testing aptitudes. These carry in-house NDT investigation methods for example industrial radiography.

So, if your company has an established follow proof of developing great amount of ASME certified pressure vessels, you can rely on their proficiency.
