Product details

The quilted steel pipe is a high-precision steel pipe material processed by cold drawing or hot rolling. Seamless Steel Pipes Because the inner and outer walls of precision steel pipes have no oxide layer, high pressure without leakage, high precision, high smoothness, cold bending without deformation, flaring, flattening without cracks, etc., Hydraulic Cylinder Tube they are mainly used to produce pneumatic or hydraulic components, such as cylinders or Cylinder, can be seamless tube.Other similar products are: GI Steel Pipe, ERW Steel Pipe , Honed Steel Tubing, Weld Steel Pipe.

Hydraulic Cylinder Tube------Used in the hydraulic cylinder of the heavy machinery, Cranes, excavator also forklifts. Material is various, mainly STKM-13CT ST52 CK45 and 1020. We can work and get the mechanical property of the clients need and extended the life of the hydraulic cylinder.
Honed tube ----- used in Elevator buffer and Hydraulic Cylinder .This kind tube have a better roughness inner the tube,ra0.2-0.4um and can use directly in the hydraulic cylinder tube. Range: ID 50-250mm and Length can work at most 6M.
Cold finished tube---- Widely Used. Processing range 30-300mm, biggest length is 11M.
