Tubes for Hydraulic Cylinders

Tenaris produces a wide range of hot rolled and cold drawn tubes in carbon, carbon micro-alloyed and special alloy steels used as hydraulic cylinder body, piston rods and telescopic cylinders by the most important world-wide earth moving machinery manufacturers, as well as by producers of lifts, tracks, tractors, dock cranes and hydraulic actuators.

Tenaris’s tubes for hydraulic cylinders are characterized by tight dimensional tolerances, controlled surface quality, high steel cleanliness and guaranteed eccentricity. They are manufactured in accordance with the most important international standards and norms: EN 10305-1, BS 5242-1, ISO 4394-1, DIN 2391-2, NF–A 49310 for cold drawn tubes and EN 10297-1, ASTM A 519 for hot rolled.

For standard working conditions (low pressure and low toughness), Tenaris offers a wide dimensional range of cold drawn and hot rolled tubes for hydraulic cylinders, in re-sulphurized or not re-sulphurized steels. Tenaris’s cold drawn tubes can be supplied in two different steel grades (PHC 355 and PHC 460) and delivery conditions (stress relieved or normalized). In hot rolled condition Tenaris produces three steel grades: E 470, E460 K2 in normalized condition and E590 K2 quench & tempered.
