4 Tips to consider Before Purchasing ASME Pressure Vessels

Pressure vessels are designed to store, or transport gasses and liquids under various pressures and temperatures. These vessels must be fabricated and designed to regulations established by The American Society of Mechanical Engineers (ASME). Due to their use in extreme environments, many factors are to be considered before buying any new pressure vessel. At BEPeterson, we get inquiries from many first-time customers about seeking tips to buy the best fit pressure vessel as per industry standards. BEPeterson provides custom ASME design capabilities and many years of fabrication experience to help customers with the best possible Pressure Vessel configuration. This post discusses facts to consider while purchasing ASME pressure vessels.

Factors to consider while buying ASME pressure vessel

The following are the top 4 factors to consider while purchasing an ASME pressure vessel.

  • Material Selection: One of the most critical factor involved in the fabrication of your pressure vessel is the material used for its construction. Prices can vary depending upon the nature of the individual material used. Some of the materials used in the fabrication process include carbon & low alloy steels, nickel alloys – Monel, 300 series & high temp SS, Inconel & Hastelloy, 2205 & 2507 duplex stainless steel, and aluminum. Material selection is driven by your process conditions. Depending on the vessels intended use you will need to determine the possible fit material for its intended application.

  • Design: Design is the crucial factor for the manufacture of new pressure vessel. The vessel must be designed such that it is able to meet the rigorous industrial demands. Weld construction is an important aspect of design, and any lapses in it can lead to catastrophic failure. BEPeterson uses the latest version software Compress to design all of vessels to ASME standards. Our fabrication experience is used to optimize designs to take full advantage of all cost considerations.

  • Industry Standards: While purchasing pressure vessels, care must be taken that it adheres to any of the following industry standards and specifications.

    • U,R,S & UM stamps
    • ASME Section 8
    • TUV
    • ISO 9001:2015 certification
    • CE, PED and CRN
  • Pressure Tests Conducted: Various tests are conducted by manufacturers to confirm the load bearing capacities, and performance of the vessel under extreme conditions. Some of the tests conducted includes Hydro-test, Ferrite Testing, PMI (Positive Material Identification), Dimensional – Fero Arm, He Leak Testing, Radiography, and NDE – PT, MT, UT. This factor will help you get an insight on the vessel capabilities. You can confirm with us the different pressure tests conducted on the pressure vessels.
