B31 History asme formed a committee to address the boiler explosion problem - 1911. asme Boiler and Pressure Vessel Code (BPVC) was the first comprehensive standard for the design, construction, inspection, and testing of boilers and pressure vessels - 1915. American Standards Institute initiated a project to develop a piping code - 1926. American Tentative Standard code for Pressure Piping 1935. Separate sections were split off starting in 1955.
