Our company are equipped with JLB250T hydraulic cold drawn set,LED120 cold rolling set, annealing surface, strong honed machine, polishing machine, lathe, saws CNC skived and roller burnished machine, kinds of testing machine. Strictly comply with ISO9001 System, assure the best quality of carbon steel tube and seamless steel tube.

Application of Carbon Tube:


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 E355 S45C and AISI 1020. We can work and get the mechanical property of the clients need and extended the life of the hydraulic cylinder.



2. honed steel tube and 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 hydraulic cylinder tube.

Range: ID 50-250mm and Length can work at most 6M.



3.Cold finished tube(cold drawn or cold rolled)---- Widely Used. Such as hydraulic breaker using carbon tube, racing car using carbon tube, elevator buffer using carbon tube, oil drilling, and so on. Processing range 30-300mm, biggest length is 11m.
