GB/T 32552-2016Automated full peripheral ultrasonic thickness testing of seamless and welded (except submerged arc-welded) steel tubes (English PDF)

GB/T 32552-2016 is the English-translated version of 无缝和焊接钢管(埋弧焊除外)的自动全圆周超声厚度检测.

GB/T 32552-2016 — This standard specifies the testing requirements and testing methods for the full-circumference ultrasonic wall thickness measurement of seamless and welded steel pipes (except submerged arc welded steel pipes) and verification procedures.

Note 1.Full circle inspection does not mean 100% scanning of the steel pipe surface. Note 2.The thickness measurement can be performed simultaneously with the full-circle delamination test (ISO 10893-8) that can meet the test requirements using the same ultrasonic probe.

In this case, the root According to the requirements of ISO 10893-8, the coverage rate of the steel pipe surface scanning inspection is determined by the minimum layer size to be detected.

This standard is also applicable to the detection of circular hollow profiles. The applicable thickness measurement range of this standard is that the nominal outer diameter is greater than or equal to 25.4mm and the minimum wall thickness is 2.6mm, unless otherwise agreed.
