Product Description

1.Seamless steel tube, seamless pipe

Widely used in the hydraulic cylinder of the heavy machinery, 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.cold drawn steel tube/cold rolled steel tube

Grade: 20#  45#  16Mn  25Mn  27SiMn  E355  ST52 S45C STKM11A STKM13A

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, honed tube, honed steel pipe

ID Tolerance: H8  H9

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.

Benifits of the precision steel tube:

(1) No Oxidation Layer on the outer and inner walls;

(2) No Leakage under high pressure;

(3) No Crake under flating and flattening;

(4) No distortion after cold bending;

(5) High precision high cleanness;

(6) Excellent brightness        

All kinds of our seamless steel pipe can be widely used for hydraulic cylinder, hydraulic parts, automobile parts, bike frame, engineering machinery, oil drilling and other field.
