Value adding services
1. Cutting
Very often, seamless heavy wall tubes are needed in specific lengths to match the requirement of the end product. We have various machines to cut heavy wall tubes to the required lengths, with narrow cutting tolerances (-0/+2 mm).
2. Testing and inspection
We can perform destructive and non-destructive material tests for heavy wall tubes, such as impact tests, hot yield tests and PMI. We organize inspections by third parties such as Lloyds Register and TÜV.
3. Restamping and marking
For identification purposes, we are allowed to restamp the heat number on the tube after cutting. We also make any other (paint) marking or stencilling you desire.
