1. Hydraulic Cylinder Tube

 

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 work and get the mechanical property of the clients need and extended the life of the hydraulic cylinder.

 

2.Honed tube ----- used in Elevator buffer and Hydraulic Cylinder .

This kind tube have a better roughness inner the tube, ra0.2-0.4um and can use directly in the hydraulic cylinder tube.

Range: ID 50-250mm and Length can work at most 6M.

 

3.Cold finished tube---- Widely Used.

Processing range 30-300mm, biggest length is 11M.

Xinpeng Have passed ISO9001 verified from 2010;

each tube of ours is strictly in quality control that can assure the product quality of Xinpeng.

Mainly produce precision tube as cold drawn/rolled tube honed and SRB tube, mainly used in Hydraulic cylinder and mechanical using.

Description

Cold finished (hard)

BK

Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation.

Cold finished (soft)

BKW

The final heat treatment is followed by cold drawing involving limited deformation.

Appropriate further processing allows a certain degree of cold forming (e.g. bending, expanding).

Cold finished and stress-relieved

BKS

Heat treatment is applied following the last cold forming process.

Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree.

Annealed

GBK

The last cold forming process is followed by annealing in a controlled atmosphere.

Normalized

NBK

The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.
