ActiveNon-destructive testing of steel tubes—Automated ultrasonic testing of seamless and welded (except submerged arc-welded) steel tubes for verification of hydraulic leak-tightness
钢管无损检测 用于确认无缝和焊接钢管（埋弧焊除外）水压密实性的自动超声检测方法
Application Summary AI generated
This standard specifies an automated ultrasonic testing method to verify the hydraulic leak-tightness of seamless and welded steel tubes (excluding submerged arc-welded types) without damaging the tubes. It is applied in the metallurgy and pipeline industries for quality control during the manufacturing of steel tubes used in pressure systems, such as boilers, gas cylinders, and fluid transport lines. The method serves as a non-destructive alternative to hydrostatic pressure testing, ensuring tube integrity for applications requiring leak-proof performance.
