Product Description
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.

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
