Precision tubes/HPL-Tubes/Cylinder tubes
Precision steel pipes are characterized by
- special dimensional accuracy of the outside and inside diameter or the wall thickness
- a good surface quality
- defined mechanical characteristics
- a high dimensional variety
Precision steel pipes produced by our corporate plants of Salzgitter
Mannesmann Precision and selected renowned and certified
precision producers simplify further processing and therefore
reduce your processing costs.
