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

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.
