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.honed 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 the hydraulic cylinder tube.

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

3.Cold finished tube(cold drawn tube and cold rolled tube)---- Widely Used. Processing range 30-300mm, biggest length is 11m 

4.heavy machinery

5.oil drilling

6.hyrdaulic breaker

7.racing car

8.elevator buffer
