GB/T42677-2023 specifies the liquid penetration detection method for seamless and welded steel pipe surface defects for nondestructive testing of steel pipes. The standard specifies the applicable steel pipe types, elaborates the principle of liquid penetration detection, and specifies the equipment, reagents, sample preparation, operation process and defect assessment required for testing. According to this standard, the surface defects of steel pipes can be accurately detected, providing a powerful means for the mass control of steel pipes, ensuring their safe use in many fields, and helping the steel pipe production and application industries to improve product mass.
