Gas Transmission and Distribution Piping Systems
The purpose of the ASME B31.8-2025 standard is to establish minimum requirements for the design, construction, inspection, testing, operation, and maintenance of gas transmission and distribution piping systems to ensure public safety and operational integrity.
Purpose and Scope of ASME B31.8-2025
ASME B31.8, Gas Transmission and Distribution Piping Systems, is a section of the overall ASME Code for Pressure Piping. Its primary purpose is to provide a comprehensive, safety-focused framework for all aspects of a gas pipeline's life cycle. This standard ensures that piping systems transporting flammable gases—primarily natural gas—are built and managed in a way that prevents failure, protects the public and environment, and complies with applicable regulations.
The scope of the standard covers:
The Code prescribes requirements for the entire process, including:
Application and Use
ASME B31.8 is the most widely used and essential code for anyone involved in the natural gas pipeline industry. It is used by:
In short, B31.8 is the authoritative document that dictates the technical and safety integrity of all natural gas transmission and distribution piping systems.
