ASME Code Symbol Stamps are used to indicate that stamped items conform to the latest edition of the ASME code. This provides you with a high degree of confidence that the pressure piping is built to the established safety standards. This also ensures that their piping projects are done correctly and in a professional manner.

The ASME Boiler and Pressure Vessel Code is a set of requirements which must be met when performing repairs to boilers and pressure vessels. In 1975, the National Board of Boiler and Pressure Vessel Inspectors realized that the lack of quality repairs could lead to a catastrophic failure. They approved the issuance of a National Board Repair “R” Stamp and the Certificate for Authorization to qualified organizations, such as Power Plant Repair Services.
