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-Tightness1 ScopeThis 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.2 Normative ReferencesThe following documents are essential to the application of this document.
