6. Deliver condition:
+NAfter the final cold drawing operation the tubes are normalized in a controlled atmosphere
Please specify the final heat treatment when sending the enquiry.

7. Inspection and testing:
Chemical analysis
Tensile test
Flattening test or Drift expanding test
Dimensional inspection
Visual examination
NDT for verification of leaking tightness
