Company

Established in December 1992, our company mainly produces various specifications of cold drawn,rolled precision steel tube,hydraulic cylinder tube and SRB Tube, which are widely used in such industries as hydro-cylinder, automobile, engineering machinery, textile machinery, printing machinery, oil drilling, etc.

Product

1.Seamless steel tube

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

ld drawn/rolled steel tube

Grade: 20# 45# 16Mn 25Mn 27SiMn E355 SAE1026

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. SRB&Honed steel tube

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.

Process

Equipped with JLB250T hydraulic cold drawn set, LD120 cold rolling set, annealing furnace, strong honed machine, polising machine,lathe,saws CNC skived and roller burnished machine, kinds of testing machine.
