The difference between honed pipe and seamless steel pipe

1, the main feature of seamless steel pipe is welded joints, can withstand greater pressure. The product can be very rough as cast or cold parts.

2,honed tube is the product in recent years, mainly the hole, the outer wall size has strict tolerances and roughness.

Delivery Condition

1. BK(+C)

the final heat treatment after cold forming, threfore small steel pipe plasticly, the plasticly degree does not guarantee

2. 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

3. NBK(+N)

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

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. GBK(+A)

after cold forming, annealing in non oxidizing medium protective gas

Company Information

precision pipe hydraulic cylinder honed pipe and tube

Yantai Xinpeng Steel Pipe Co,.Ltd. is one of the best suppliers of the precision tube and hydraulic cylinder tube in North of China. Since 2002 cold drawn machine set importing, Xinpeng become a big precision steel pipe manufacture with 500Mt month productivity in the next 12 years.

Products widely used in the hydraulic cylinder of the heavy machinery, Cranes, excavator, forklifts and the Petrol industry.

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 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 2015; each tube of ours is strictly in quality control that can assure the product quality of Xinpeng.
