Published as a companion to B31.8, this standard is dedicated entirely to Pipeline Integrity Management (PIM).
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
= Design Factor (determined by location class or fluid type) = Longitudinal Joint Factor = Temperature Derating Factor Phase 2: Construction and Inspection
This is the baseline standard, primarily governing piping systems in electric generating stations, industrial plants, and central heating systems. It deals with high-pressure steam and water systems. Because of the extreme temperatures and pressures involved in power generation, B31.1 sets rigorous standards for materials and stress analysis.
While it isn't a replacement for the full standards or professional engineering judgment, it serves as an essential roadmap for navigating the ASME B31 Code Series . Core Standards You'll Find Inside
= Design Factor (determined by Location Class, varying from 0.72 down to 0.40) = Longitudinal Joint Factor (weld quality coefficient) = Temperature Derating Factor By altering the Design Factor (
