Which code primarily covers Process piping?

• A. B31.1
• B. B31.3
• C. B31.9
• D. B31.5

Answer: (B)

Process piping is governed by a code that specifically covers piping systems used to transport process fluids in chemical plants, refineries, and similar facilities. This code provides the design, material, fabrication, testing, and inspection requirements for piping that handles process services, where fluids can be hazardous, hot, or under pressure. It is the primary reference for process piping because its scope and criteria are tailored to the unique demands of process service, including fluid properties, temperature and pressure ranges, and the need for reliable controls and integrity. The other codes cover different domains: one focuses on power piping used in energy generation and large industrial plants, another on piping within buildings and building services, and another on mechanical piping associated with equipment and utility systems. While there can be overlap and interfaces with those codes, the code that most directly applies to process piping is the one dedicated to process piping.
