B31.3 (Process Piping)

B31.3 is a standard developed by the American Society of Mechanical Engineers (ASME) that outlines the design, materials, fabrication, and inspection requirements for piping systems used in chemical plants, petroleum refineries, and other industrial facilities. Its purpose is to ensure safety, reliability, and efficiency in process piping by providing guidelines that help prevent leaks, failures, and accidents. By adhering to B31.3, engineers and manufacturers can create piping systems that effectively handle various substances under different conditions, protecting both people and the environment.
