Cold drawn(rolled) precision steel pipe and the general difference between ordinary seamless steel pipe:

1, the general characteristics of ordinary seamless steel pipe is welded seam, can withstand greater pressure. The product can be very rough as cast or cold parts.

2, cold drawn precision steel pipe is the product in recent years, mainly the hole, the outer wall size has strict tolerances and roughness.

Cold drawn (rolled) precision steel pipe features:

1. smaller diameter.

2. High precision can be done small batch Health

3. Cold drawn (rolling) finished high precision, good surface quality.

4. Steel pipe cross-sectional area is more complex.

5. Steel pipe performance is superior, the metal is relatively dense.

our tubes

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
