High pressure tubes

Seamless austenitic cold redrawn stainless steel, alloy 316/316L tubing for high pressure applications, where both high strength and corrosion resistance are desired. MST Edelstahlrohr GmbH high pressure tubes are characterized by high yield strength and high tensile strength in connection with high elongation. The high pressure tubes are used for fluid handling in a wide range of industry such as oil and gas, (petro-)chemics, hydraulic systems, shipbuilding and research. We store the common outer diameters 1/4", 3/8", 9/16", 3/4" and 1" with varying wall thickness for applications from 1.380 bar/20.000 PSI up to 10.350 bar/150.000 PSI.
