Welding Requirements for Pipelines

This standard specifies the welding, heat treatment, Nondestructive Testing
(NDT), and hardness testing requirements for welding pipelines and equipment (e.g., scraper traps) to ASME B31.4 and ASME B31.8, both onshore and offshore, including shop and field fabrication, repair, or modification. Distribution and other facilities which use B31.4 as the piping design code are also included. These requirements are in addition to the requirements of ASME B31.4, ASME B31.8, API STD 1104, and ASME SEC IX.
