Asme Pipeline Standards Compendium Jun 2026

What specific is your pipeline system transporting?

When an inspection tool (like a smart pig) detects metal loss or corrosion, engineers use B31G formulas to calculate the safe maximum allowable operating pressure (MAOP) of the damaged section.

Developed to address the global shift toward clean energy, this code covers piping in gaseous and liquid hydrogen service. It accounts for hydrogen embrittlement by mandating specific material selection, lower design stress factors, and specialized welding qualifications. Key Technical Aspects Covered in the Standards

The ASME pipeline compendium standardizes several mathematical equations and engineering workflows that dictate how pipelines are built. The Design Factor and Hoop Stress Calculations

Both B31.4 and B31.8 require Charpy V-notch impact testing for low-temperature or high-stress service, preventing brittle fracture. asme pipeline standards compendium

ASME B31.8: Gas Transmission and Distribution Piping Systems

A vital supplement dedicated entirely to Managing System Integrity of Gas Pipelines . It outlines the industry standard for risk assessment and threat prevention (e.g., stress corrosion cracking and third-party damage). ASME B31.3: Process Piping

: Provides a unified overview and roadmap of ASME's extensive pipeline-related codes, such as the B31 series (e.g., B31.4 for liquid petroleum and B31.8 for gas transmission). Availability : The compendium can be purchased or accessed through the ASME Standards Catalog or authorized distributors like Intertek Inform Related Pipeline Standards What specific is your pipeline system transporting

To help me tailor more specific information for your project, what will your pipeline transport, and what is the geographic location class of the installation? Share public link

Use B31.4 for hydrocarbons/liquids, B31.8 for gas, or B31.12 for hydrogen.

While not a "cross-country pipeline" standard in the traditional sense, B31.3 is an essential part of any pipeline compendium.

While not design standards, B31.8S and B31.4 reference ILI (smart pigs) as a key integrity verification tool. It accounts for hydrogen embrittlement by mandating specific

Using a recognized compendium allows engineering firms to standardize designs across international borders, simplifying supply chain procurement and cross-border project execution.

The primary B31 codes are supported by supplementary standards that address specific lifecycle phases and threats.

Factory-Made Wrought Buttwelding Fittings. This standard governs the geometry and pressure-holding capacity of elbows, tees, reducers, and caps.

Instead of navigating through multiple, separate volumes of CFR and ASME standards, users can find the relevant citations in one place. Key Areas Covered by PTB-9
