Seamless precision and hydraulic line tubes

Seamless precision and hydraulic line tubes

Seamless precision steel tubes are produced by cold forming hot-rolled tubes (hollows) and are characterized by special features such as high dimensional accuracy and smooth surface.

Seamless hydraulic-pneumatic line tubes (HPL tubes) are seamless cold-finished precision steel tubes which are mainly used in hydraulically or pneumatically operated systems as lines and are therefore suitable for tumescent loads.
