Location classes (population density factors), fracture control, and maximum allowable operating pressure (MAOP) calculations.
The ASME Pipeline Standards Compendium is more than a collection of rules; it is an indispensable roadmap for modern infrastructure engineering. By synthesizing design formulas, component dimensions, and risk-management protocols into a single framework, it ensures that the global network of oil, gas, and chemical pipelines operates with the highest degree of structural integrity and public safety.

The is an essential document that serves as a critical bridge between complex engineering codes and stringent federal regulations. While the specific standards it covers—the B31 family—are constantly updated to meet new technological and safety challenges, the PTB-9 provides an invaluable structure for understanding their role.
= Class location factor (determined by human population density near the pipeline).
This guide serves as a comprehensive overview of the , breaking down the essential codes, their core applications, and how to utilize them effectively in modern engineering. 1. What is the ASME Pipeline Standards Compendium? asme pipeline standards compendium
: Provides the legal and technical benchmarks required by regulatory bodies worldwide, such as the U.S. Department of Transportation (DOT) and the Pipeline and Hazardous Materials Safety Administration (PHMSA).
While the B31 series dictates how a pipeline is designed and built, the ASME compendium relies on other series to define the physical components.
The energy landscape is changing rapidly, and ASME standards are evolving to keep pace. Based on the latest revisions of the B31 codes, the future of pipeline standards is being shaped by several key trends:
Integrate B31.8S principles into Geographic Information Systems (GIS) for real-time asset tracking. To help point you toward the right resources,

Repurposing natural gas pipelines to carry hydrogen causes a risk of hydrogen embrittlement, which weakens traditional carbon steel. The compendium works alongside (Hydrogen Piping and Pipelines) to specify the required materials, lower design factors, and strict testing protocols needed for hydrogen transport. Carbon Capture, Utilization, and Storage (CCUS) Transporting dense-phase or supercritical CO2CO sub 2
Standards provide rigorous methods to verify MAOP after modifications, corrosion, or hydrostatic testing.
B31.8S (below) is the integrity management supplement to B31.8. = Class location factor (determined by human population
Federal regulations often "incorporate by reference" various technical standards from organizations like ASME . For an engineer or regulator, jumping between legal text and dense engineering codes can be cumbersome.
Focuses on pipeline systems transporting liquids such as crude oil, petroleum products, and anhydrous ammonia [2].
This includes everything from long-distance high-pressure transmission lines and compressor stations to smaller gas mains and service lines that run up to the outlet of a customer’s meter set assembly. The latest edition as of this writing is ASME B31.8-2025.
