Factors to Consider While Choosing Industrial and Commercial Pressure Vessel Fabrication Services

In industrial terms, a pressure vessel is a strategically constructed container that holds elements (gases, liquids, semi solids) at pressure levels that are considerably different from the ambient pressure levels. As the container is responsible for holding the elements under a critically high/low pressure, it is crucial to fabricate the pressure vessel using the highest engineering expertise in order to avoid even the slightest of fault or loophole, which can lead to fatal consequences. The vital roles played by these pressure vessels for several industrial applications thus call for the requirement of flawless use of pressure vessel fabricators.

What are the Varied Applications of Pressure Vessels?

Pressure vessels nowadays are used for numerous critical industrial and commercial applications that include the following:

  • Geothermal plants
  • Aerospace industry
  • Food and beverage sector
  • Nuclear reactors
  • Steam separators
  • Fractionation towers
  • Aquatic vessels and ships
  • Oil and gas refineries
  • Mining sites
  • Pipelines for carrying heated water for domestic purposes and gases like ammonia, LPG, LNG, CNG, butane, chlorine, propane etc

What Aspects to Weigh Before Selecting Industrial and Commercial Pressure Vessel Fabrication Services?

These demanding applications that are met with the help of pressure vessels are evident of the fact that commercial pressure vessel fabrication services require a great deal of technical expertise, precision and engineering proficiency.

Considering the following aspects about the pressure vessel fabricator or service provider can help you make the best decision about availing perfect solutions:

  1. Make sure that the selected fabrication service provider is certified with an ASME (American Society of Mechanical Engineers) code.  It is advisable to work with a firm that holds critical stamps such as U, U2, U3, PP and S to avail for customized or standard pressure vessel services.
  2. Besides making sure that the firm holds these essential certificates and stamps, also remember to check if the service provider holds the National Board R-Repair Stamp. This would allow you to consult the services of the same firm for any future maintenance and repair requirements as it is suggested to take help from the original suppliers or manufacturers for any future repair or maintenance work.
  3. According to experts, customers should go for a well-rounded service provider who besides pressure vessels has also gained expertise in manufacturing autoclaves, heat exchangers, cryogenic vessels, reactors, separators, power piping, vacuum chambers, weld overlays, clad vessels and so on. This signifies their broad and in-depth technical superiority and powerful resource system needed for the same.
  4. Lastly, it is also essential to check the testing and inspection facilities that the service provider employs to verify and scrutinize the performance, precision and efficiency of the manufactured units. It is vital for the selected firm to carry the most latest and innovative testing capabilities such as in-house NDT capabilities and industrial radiography.
