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 27SiMn E355ST52 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 honed steel pipe, honed tube
ID Tolerance: H8 H9 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
