GB/T42662-2023 stipulates the automatic ultrasonic detection method for delamination defects of steel strips/plates for welded steel pipes. The standard specifies the type of steel strips/plates that are applicable, describes the principle of automatic ultrasonic testing, and specifies the testing equipment, preparation work, operation process and defect assessment in detail. According to this standard, the delamination deficiency of steel strips/plates can be accurately detected, and the source of the welded steel pipe mass can be checked. It helps the steel pipe production industry to improve the mass control of raw materials and ensure the safe application of welded steel pipes in construction, energy and other fields.
