GB/T 31925-2015
ActiveUltrasonic test methods of heavy wall thickness seamless steel pipes and tubes
厚壁无缝钢管超声波检验方法
Application Summary AI generated
This standard specifies the ultrasonic testing methods for detecting internal and surface discontinuities in heavy wall thickness seamless steel pipes and tubes. It is applied in the metallurgical industry for quality control during manufacturing, particularly for pipes used in high-pressure boilers, oil and gas transportation, and structural applications where wall thickness exceeds typical ultrasonic testing limits. The standard ensures reliable flaw detection by defining equipment, calibration procedures, and acceptance criteria specific to thick-walled tubular products.
