Mechanical Property of carbon tube

Delivery condition of carbon tube

1. NBK(+N) of seamless pipe

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

2. GBK(+A) of seamless pipe

after cold forming, annealing in non oxidizing medium protective gas

3. BK(+C) of seamless pipe

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

4. BKW(+LC) of seamless pipe

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) of seamless pipe

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

About our company:

Established in Dec 1992, with registered capital of 5 million Yuan, Yantai Xinpeng Steel Pipe Co.,Ltd has more than 20 years experience in manufacturing and exporting steel pipe. Our company mainly produces various specifications of cold finished precision steel pipe, which are widely used in hydraulic Pneumatic cylinder for automobile, engineering machinery, textile machinery, printing machinery, racing car, elevator buffer, oil drilling and other field.

What we can provide are seamless steel tube, carbon steel tube, cold drawn steel tube, cold rolled steel tube, SRB steel tube, polished steel tube, hydraulic steel tube, cylinder steel tube, and so on.

We Have passed ISO9001 verified from 2008,each carbon tube of ours is strictly in quality control that can assure the saemless pipe quality of Xinpeng.

Application of seamless pipe

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 AISI1020. We can work and get the mechanical property of the clients need and extended the life of the hydraulic cylinder.

2.honed tube and SRB 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.

4. Seamless steel tube

 What we can provide are:

--Seamless steel pipe

--Carbon steel pipe

--Cold drawn steel pipe

--Cold rolled steel pipe

--Honed steel pipe

--Hydraulic steel pipe

--Cylinder steel pipe
