Application:
1.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.
2.SRB 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.
3.Cold finished tube---- Widely Used. Processing range 30-300mm, biggest length is 11M.
