Codes and Standard Specifications

Rules for the design, fabrication, and inspection of pressure vessels, piping and tanks are provided by codes that have been developed by industry and/or regulatory agencies in various countries.
The ANSI/ASME Boiler and Pressure Vessel Code provide a list of acceptable steels and allowable stress values. The code also provides the method for calculating the required minimum thickness of various components based on design temperature and pressure the need for heat treating during fabrication and Inspection requirements is also defined based an die alloy selected and the pressure-wall thickness.
