Which code section is used to regulate Process Piping?

B31.3 is the section of the ASME Boiler and Pressure Vessel Code that specifically addresses process piping. This code covers the requirements for the design, materials, fabrication, inspection, and testing of piping systems for the chemical, petrochemical, and pharmaceutical industries, among others. It ensures that the piping is safe and reliable for the transport of fluids in these critical processes.

B31.1 pertains to power piping and is focused on piping used in power generation technologies, while B31.7 deals with piping for nuclear facilities. B31.9 covers building services piping, which is related to heating, cooling, and plumbing in buildings but does not specifically apply to process piping in industrial contexts. Therefore, B31.3 is the appropriate section to refer to when regulating process piping, as it encompasses the specific requirements and safety standards necessary for handling process-related fluids.
