Remember: ASME codes set the minimum standard. A well-organized compendium elevates you to best-in-class operations. Start building yours today.
Always check the latest edition (e.g., B31.4 – 2022, B31.8 – 2022, B31.12 – 2023). Local regulations (e.g., PHMSA in the US, CER in Canada) may mandate specific editions. asme pipeline standards compendium
The compendium identifies and summarizes the technical requirements of several critical ASME B31 series ASME B31.4 Note: Always check the latest edition (e
The compendium highlights several heavy-hitters in the pipeline world: | Include fluid phase diagrams in your compendium’s
| Pitfall | Consequence | Compendium Fix | | :--- | :--- | :--- | | Using B31.8 for a liquid CO2 pipeline | CO2 is a dense fluid; B31.4 is required for liquid-phase CO2. | Include fluid phase diagrams in your compendium’s scope section. | | Ignoring B31.8S for old pipelines | Failing to reassess legacy lines for HCAs leads to regulatory fines. | Mandate a “legacy integrity review” workflow using B31.8S. | | Confusing B31.12 Tier 1 vs Tier 2 | Using Tier 1 rules for a high-pressure hydrogen line risks embrittlement failure. | Create a decision tree: If pressure > 5,000 psi → Tier 2 requirements. | | Overlooking B31Q for welders | Unqualified welders produce code-violating joints that fail unexpectedly. | Link B31Q qualification records to each weld traceable number (WTN). |
