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.

Cold forming increases the stability level of steel. Therefore the wall thickness can be reduced in comparision to the same steel type of hot rolled pipes combined with a significant weight reduction of the component can be achieved.
