Which code section would be relevant for the installation of petrochemical piping?

The relevant code section for the installation of petrochemical piping is B31.4. This section specifically deals with the transportation of liquids and slurries, including those typical in the petrochemical industry, such as oil, natural gas liquids, and other hazardous liquids.

B31.4 outlines guidelines that cover material specifications, design, fabrication, installation, and testing requirements for piping systems in these applications. This makes it particularly important for ensuring safety and compliance with industry standards while handling potentially hazardous substances.

The other sections, while they deal with piping systems, focus on different types of systems and applications. For example, B31.1 pertains to power piping, which is more aligned with steam and hot water systems, while B31.6 addresses the transportation of refrigerants in water and is not applicable to petrochemicals. B31.7 includes guidelines for nuclear piping systems, which is also outside the scope of petrochemical piping installations. Consequently, B31.4 is the most appropriate reference for those involved with petrochemical piping systems.
