Main products

1. Hydraulic Cylinder Tube------Main products of Xinpeng,

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.SRB tube ----- used inElevatorbuffer 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 2008; each tube of ours is strictly in quality control that can assure the product quality of Xinpeng.

Mechanical Property

Application

Widely used in hydraulic system with precision steel tube, injection molding machine with precision steel tube, hydraulic press with precision steel tube, shipbuilding with steel tube, EVA foaming, hydraulic machinery, hydraulic cutting machine, shoe making machinery, hydraulic equipment, high pressure tubing, hydraulic tubing, card sets of joints, pipe joints, rubber machinery, forging machinery, casting machinery, engineering machinery, automotive high pressure steel pipe concrete pump, sanitation vehicle, automobile industry, shipbuilding industry, metal processing, military industry, diesel engine, the internal combustion engine, air compressor, construction machinery, forestrymachinery, etc.

Delivery condition

1. NBK(+N)

after cold forming, eventually above phase transition point, in a protective atmosphere of annealing oxidation medium

2. GBK(+A)

after cold forming, annealing in non oxidizing medium protective gas

3. BK(+C)

the final heat treatment after cold forming, therefore small steel pipe plastically, the plastically degree does not guarantee

4. BKW(+LC)

after final heat treatment, a tiny cold drawing deformation, continue again when machining steel pipe allowed inside certain limits cold deformation(bending, flaring)

5. BKS(+SR)

have a stress relief after cold forming, heat treatment, steel pipe can be carried out within a certain limit in the appropriate processing.
