Application Summary AI generated

This standard specifies the method for detecting stress concentration and defects in ferromagnetic pipelines using weak magnetic field measurement technology. It is applied in industries such as oil, gas, and petrochemicals for in-service pipeline integrity assessment, particularly for identifying areas of high stress or early-stage damage without requiring surface preparation or direct contact. The method is suitable for field testing of buried or above-ground pipelines under operational conditions.
