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
