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

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

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

Delivery Condition

1. BK(+C)

the final heat treatment after cold forming, threfore small steel pipe plasticly, the plasticly degree does not guarantee

2. BKS(+SR)

have a stress relief after cold forming, heat treatment, steel pipe can be carried out within a certain limit in the appropriate processing again

3. NBK(+N)

after cold forming, eventually above phase transition point, in a protective atmosphere of annealing oxidation medium

4. BKW(+LC)

after final heat treatment, a tiny cold drawing deformation, continue again when machining steel pipe allowed inside certain limits cold deformation(bending, flaring)

5. GBK(+A)

after cold forming, annealing in non oxidizing medium protective gas

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.
