GB/T 18256-2015 — This standard specifies the seamless and welded (except submerged arc welded) ultrasonic shear wave (generated by the probe or discrete phase control technology) automatically detects Party French general requirements, in order to confirm its hydraulic compactness.
This detection method is mainly used to detect longitudinal discontinuities. When necessary, the manufacturer to decide whether to adopt Lamb wave detection. This standard applies to detect an outside diameter of less than 10mm, and the ratio of outside diameter and wall thickness of the pipe is not less than 5.
