Product Details

 

Company introduction:

 

Located in Yantai, our company Yantai Xinpeng Steel Pipe Co., Ltd, is in(APEC) Science& Technology Industrial Park, with convenient transportation. Established in Dec 1992, with registered capital of 5 million Yuan, we have 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, oil drilling and other field.

 

Our company is equipped with JLB 250T hydraulic cold drawn machine set, LD120 precision cold rolled machine set, multiple precision straightening machine, box heat treat furnaces(8000-10000mm).In 2002, our company equipped one set advanced CNC skived and roller burnished machine SRB-600mm, several Powerful honed machine, Combined cold drawn, cold rolling, heat treatment and SRB process to produce the best quality products. Standard:GB/T8713-88, GB/T3639-2000 or according to customers’ requirement. Material usual 20#,45#,16Mn,25Mn,27SiMn,St35,St52,etc.

 


 

Specifications:

1.Standard:GB/T8713,GB/T3639,DIN2391,EN10305,ASTMA519,ASTMA106-2006

2.Grade: 20#(aisi1020,ck20),45#(aisi1045,ck45),st52(16Mn,Q345D),25Mn(stkm13c-t),27SiMn

3.OD:30-250mm

4.ID tolerance:H7,H8,H9

5. Wall thickness:10%×ID

6.Surface roughness:Ra 0.02— 0.4μm

7. Delivery condition:BK,BKW,BKS,GBK,NBK

8.Ovality: ≤ 0.10-0.20

9.Curvature:0.3

 

 

Delivery condition:

 

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 again
