Our Main products of carbon tube

1.Seamless steel tube and carbon steel tube

Widely used in the hydraulic cylinder of the heavy machinery, Cranes, excavator also forklifts. Material is various, mainly STKM-13CT ST52 CK45 S45C ASTM A53 A106 and AISI 1020. We can also offer as customized seamless steel tube.

2.cold drawn steel tube/cold rolled steel pipe

Grade: 20#  45#  16Mn  25Mn  Q345 27SiMn  E355  ST52 CK45 STKM11A STKM13A STKM13C

Standard: GB/T8713  GB/T3639  DIN2391  EN10305  ASTMA519

Range: 30-300mm

Length: 11m(max)

The cold process can change the thickness of tube to meet client's request and offer better mechanical property. 

 3. Honed steel tube&SRB steel pipe

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 inside tube more smooth which can be used for cylinder directly.
