Asme Pipeline Standards Compendium ((free)) -

The ASME Pipeline Standards Compendium (PTB-9) is a technical guide that aligns ASME B31 pressure piping codes with U.S. federal safety regulations. It provides plain-language summaries and excerpts covering key standards such as B31.4 for liquid pipelines and B31.8 for gas pipelines, serving as a vital reference for compliance.

Her first assignment was simple on paper: review a proposed pipeline route and confirm compliance with the compendium everyone called “the Code” — a shorthand for the ASME pipeline standards adopted by the city. She opened the binder in a quiet corner of the archive and let the scent of paper and machine oil settle: design principles, material selection, welding procedures, testing requirements. Each section was a promise: if you followed this, lives could be safer. asme pipeline standards compendium

2. ASME B31.3: Process Piping

Perhaps the most widely used standard in the chemical and petrochemical industries, B31.3 covers piping found in petroleum refineries and chemical plants. It is distinct for its categorization of fluids into "Normal," "Category D" (non-flammable, non-toxic), and "Category M" (toxic services), applying stricter safety factors to pipelines carrying hazardous substances. Pressure Design: Determines wall thickness based on internal

• Pressure Design: Determines wall thickness based on internal pressure, using the Barlow formula.
• Location Class: Unlike gas, B31.4 does not use location classes for design factor adjustments but focuses on operational stress.
• Valve Spacing: Requires automatic shutoff valves at specific intervals (typically 15 miles for high-consequence areas).
• Surge Analysis: Mandatory hydraulic transient (water hammer) analysis for liquid pipelines.

Key Highlights:

ASME B31.8S (Integrity Management): Specifically tailored for gas pipeline operators to develop and implement effective integrity management programs, reducing risks of malfunction and system downtime. Gas Transmission and Distribution Piping Systems - ASME
