ASME U Stamp, R Stamp & Vessel CRN

Everything About ASME U Stamp, R Stamp & Vessel CRN

An ASME certification or mark is the way to tell the regulators, customers, and industries that your organization is committed to quality and safety. It also indicates that your products are reliable, safe and high-quality. Thus, it is advisable to get your product registered under the appropriate authority to avoid any legal complications in the form of penalties.

Three Commonly Used Certifications for ABSA Pressure Vessels

  1. Certifications for ABSA Pressure VesselsASME U Stamp
    Over 100 countries globally accept the ASME Boiler and Pressure Vessel Code or ASME BPVC to meet government safety rules and regulations. The ASME U Stamp is an indication that the pressure vessels adhere to ASME’s guidelines including design, fabrication, inspection, and testing. It is used for the certification and acceptance of pressure vessels. Seeing the “U” symbol on a product ensures that it meets the latest edition of the Code. It also affirms that the vessel is designed and manufactured according to the standards of ASME.
  2. ASME R Stamp
    The National Board of Boiler and Pressure Vessel Inspectors offers the R symbol stamp for the alteration and/or repair of pressure vessels, boilers, and other pressure-retaining items after subjecting the organization to an onsite review. Based on the jurisdictional requirements, the inspection may be handled by a member of the National Board or a representative.
  3. Vessel CRN
    Vessel CRN refers to the Canadian Registration Number. It is issued by an approved safety authority in each province and territory in Canada for pressure vessels, boilers, or any other fitting that operates at a pressure more than 15 pounds per square inch (psi). It is quite similar to the ASME standards, but slightly complicated because if you want your vessel certified across the country, you’ll have to meet the requirements in seven organizations or jurisdictions.
    For any pressure vessels manufactured outside of Canada to be used in Canada, they must be registered by National Board and have a CRN.
