Quilted Steel Pipe is a high-precision steel pipe material processed by cold drawing or hot rolling. Due to the characteristics of no oxide layer on the inner and outer walls of the Precision Steel Tube, no leakage under high pressure, high precision, high smoothness, no deformation in cold bending, no flaring, no cracks in flattening, etc., it is mainly used for the production of pneumatic or hydraulic components, such as air cylinders or cylinders, Can be seamless tube. Our hot-selling products include structural steel pipes, fluid steel pipes, boiler steel pipes, etc.

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.
