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.

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
