Managing System Integrity of Gas Pipelines
Purpose and Scope of ASME B31.8S-2025
ASME B31.8S, Managing System Integrity of Gas Pipelines, is a supplementary standard to ASME B31.8. While B31.8 focuses on the initial design and construction of gas pipelines, B31.8S focuses on the long-term management and maintenance of those pipelines, particularly to prevent failures and incidents over time.
The core objective of the standard is to guide pipeline operators in developing and implementing an Integrity Management Program (IMP) that utilizes proven industry practices and processes. This standard applies to onshore gas pipeline systems constructed with ferrous materials.
The standard describes the following key elements for managing pipeline integrity:
Application and Use
ASME B31.8S is the foundation for the integrity management programs required by regulatory bodies, such as the U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA). It is primarily used by:
In essence, while B31.8 ensures pipelines are built safely, B31.8S ensures they operate safely throughout their useful lives by systematically managing threats and risks.
