Scope

Scope: This standard applies to components and supports of above-ground ferromagnetic metal pressure pipelines, as well as welds. It is used for magnetic memory testing and result evaluation of stress caused by factors such as foundation settlement and temperature changes. After excavation of underground pipelines, the magnetic memory testing of pipeline stress can also be conducted in accordance with this standard. Magnetic memory testing of stress in welds of pressure vessels and other pressure-bearing equipment can be conducted by referring to this standard. Austenitic stainless steel pipelines, which are ferromagnetic under certain conditions, can also be tested for pipeline stress by referring to this standard. Main technical content: This standard specifies the terms and definitions, principles, application principles, general requirements, experimental steps, result evaluation, experimental quality assurance and control, and experimental records and reports for magnetic memory testing of stress in above-ground ferromagnetic metal pipelines.
