Hydraulic cylinder tube
1.The hydraulic cylinder tube is the main part of the hydraulic cylinder.
2.The inner hole of the hydraulic cylinder tube usually precision processed by boring,reaming,rolling
or honing.
3.By these process can ensure the piston,sealing elements and the supportelements move smoothly,
then ensure the sealing effect and reduce the abrasion.
4.The hydraulic cylinder tube will bear big pressure,so need high strength and stiffness.
Yantai Xinpeng Steel Pipe Co,.Ltd. is one of the best suppliers of the precision tube and hydraulic cylinder tube in North of China. Since 2002 cold drawn machine set importing, Xinpeng become a big precision steel pipe manufacture with 500Mt month productivity in the next 12 years.
Products widely used in the hydraulic cylinder of the heavy machinery, Cranes, excavator, forklifts and the Petrol industry.
1. Hydraulic Cylinder Tube------Main products of Xinpeng,
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.
Xinpeng Have passed ISo9001 verified from 2015; each tube of ours is strictly in quality control that can assure the product quality of Xinpeng.
