we can provide such pipes:

1.Seamless steel tube and carbon tube

Widely used in oil,drilling, gas, Cranes, excavator also forklifts. Material is various, mainly STKM-13CT ST52 CK45 and AISI 1020. We can also offer as customized seamless steel tube.

2.precision steel tubes

cold drawn steel tube/cold rolled steel pipe/cold drawn pipe/cold rolled tube

Grade: 20#45#16Mn25Mn Q345 27SiMnE355ST52 STKM13A STKM13C

Standard: GB/T8713GB/T3639DIN2391EN10305ASTMA519

Range: 30-300mm

Length: 11m(max)

The cold process can remove the oxide layer outside to improve surface and offer better mechanical property, also can change ID,OD,WT to meet every client request.

3. Honed steel tube&SRB steel pipe, honed tube

ID Tolerance: H8H9 or as client's request

ID Roughness: RA0.4micron(max)

Length: 6m(max)

Inner roughness: Ra0.2-0.8um

Straightness: 1:1000 or customized

This process can improve the roughness of the inner tube to 0.2-0.8um and make tube for cylinder using directly.

4.Hydraulic cylinder steel tube, hydraulic tube, cylinder tube

The difference between precision steel pipe and seamless pipe

1. the seamless steel tube with obvious difference is that dimensional accuracy, can be up to 0.1mm.

2. high precision steel pipe diameter surface finish, the customer without processing can be used directly and ordinary seamless steel tube to the customer and lather, polishing processing.

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.

Company Information

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.
