Our Company

Yantai Xinpeng  Steel Pipe Co.,LTD. was estabilished in 1992, producing various specifications high precision steel tube. During the past 20 years, Yantai Xinpeng Steel Pipe Co,.Ltd. has become one of the best suppliers of the precision tube and hydraulic cylinder tube in North of China by the our efforts. Our suppliers are some most famous steel factories in China , such as  BAOSTEEL, PANGANGGROUP, HUBEI XINYEGANG STEEL CO., LTD., which assure our high quality material. Our company is also the distributor of several domestic well-known steel tube plants in Shandong, and mainly distributes seamless steel tubes of all kinds of materials.

Our Product

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.

The benifits of our products:

• Superior surface finish
• Dimensional accuracy and excellent micro-structure uniformity
• Enhanced machinability
• High strength to weight ratio
• Tight tolerances, resulting in reduced machine time
• Applications: hydraulic cylinders, rollers, structural apps, truck and automotive parts.

Our Product Process

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

Packaging&Shipping

1. bundle packing

2. marking as per customer's requests

3. paint on the pipe as per customer request

4. pipe caps as customer request

Delivery Conditions

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 

 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 machiner...
