Why ASME ? The American Society of Mechanical Engineers Boilers and Pressure Vessels Codes except for Transportation Tanks (hereafter as ‘ASME Codes’) have been adopted as boilers and pressure vessels safety rules by almost all states of US and provinces of Canada. It is mandatory that all boilers and pressure vessels, which are used in North America and in the scope of ASME Codes, shall be designed, fabricated and inspected in accordance with ASME Codes and stamped ASME Code Symbol stamps.
Why ASME? It is not a mandatory requirement for the boilers and pressure vessels, which are neither used in North America nor in the scope of ASME Code, to bear ASME Code symbols. However, above mentioned boilers and pressure vessels may be stamped ASME Code Symbols in the following cases providing that they are designed, fabricated and inspected in conformity with ASME Codes: that required by the end user; or that required by the local Jurisdiction in the locations where the boilers or pressure vessels are used (e. g. Australia, South America).
