ASME is a leading developer of codes and standards in the mechanical engineering community. These standards enhance public safety and health as well as promote innovation.
The ASME (American Society of Mechanical Engineers) mark is a single certification marketing to signify the international mark of safety and quality. Recognized worldwide, manufacturers that provide ASME have a rigorous quality program, and a third-party review to authorize the use of the mark.
The U mark certifies that the pressured tanks or vessel conforms to the latest edition of the ASME code and that the pressure vessel has been designed and manufactured in accordance with ASME. All aspects are approved by a Third party ASME Authorized Inspector (AAI). U stamps require an ASME inspector to witness the ASME hydro test.
Companies with a U mark undergo a review with the National Board every three years.
The UM mark certified that the pressure vessel or tank conforms to the latest edition of the ASME code and that the pressure vessel has been designed and manufactured in accordance with ASME. The UM vessel’s designation is related to the size of the tank/vessel.
While the American Society of Mechanical Engineers writes the rules for the new construction of pressure vessels and tank, the National Board of Boiler and Pressure Vessel Inspectors write the inspection code for new and repaired vessels.
The National Board of Boiler and Pressure Vessel Inspectors require a Certificate of Authorization and R stamp for the repair or alteration of boilers, pressure vessels and other pressure retaining equipment.
Apache has been ASME certified for over 45 years. In addition to ASME, Apache is accredited in many other global standards. By setting parameters for quality and compliance, we offer greater value for our custom stainless ASME tanks and vessels.
