Hydraulic- and pneumatic pressure tubes (HPL-Tubes)
galavanised / passivated (chrom-VI-free)
Within the large group of steel tubes, precision steel tubes occupy a special position. It is based on the characteristics of these tubes, where the advantages of precision steel tubes are the result of cold forming by drawing or rolling. The resulting consolidation can be used selectively and can be reached e.g. increased hardness values that can only be achieved by heat treatment at hot-rolled tubes.
HPL tubes are seamless cold-drawn precision steel tubes predominantly for use as pressure lines in hydraulically or pneumatically operated equipment.
Alternatives with even higher corrosion protection against white and red rust (> 600 hours) are available on request
