Cylinder pipes

You can obtain our cylindrical pipes in a seamless or welded version. For these items, the thermal treatment is usually stress-relief annealed (+SR).

Cylindrical pipes are often used as the main focus in hydraulic and pneumatic applications. For example, as cylinder jackets in which piston rods run. For this, the inner surface of the cylindrical pipes must have a narrow tolerance and very low roughness characteristics. Depending on the version, tolerance fields H8 or H9 are possible here for seamless pipes, as well as H9 and H10 for welded pipes.
