Non-Destructive Testing of Steel Tubes - Automated

Electromagnetic Testing of Seamless and Welded

(Except Submerged Arc-Welded) Steel Tubes for the

Verification of Hydraulic Leak-Tightness

1 Scope

This document specifies the automated electromagnetic testing of seamless and

welded steel tubes, with the exception of submerged arc-welded (SAW) tubes, for

verification of hydraulic leak-tightness. The eddy current testing method is applicable

to test the steel tubes with outer diameter greater than or equal to 4mm; while the

magnetic flux leakage testing method is applicable to test the steel tube with outer

diameter greater than 10mm.

This document may also be applicable to the testing of hollow sections.

NOTE: Electromagnetic testing using magnetic flux leakage method is not applicable to

austenitic stainless-steel tubes.
