Honed tube features
1, improved the surface roughness, roughness can be basically Ra ≤ 0.08 micro.
2, correction roundness, oval can be ≤ 0.01mm.
3. improved the surface hardness, so that the deformation of the force to eliminate, improve the hardness HV ≥ 4 °
4, after processing residual stress layer, improve fatigue strength increased by 30%.
5, improved with the quality, reduce wear and tear to extend the life of parts, but the parts of the processing costs instead.
we can provide such pipes:
1.Seamless steel tube and carbon tube
Widely used in oil,drilling, gas, Cranes, excavator also forklifts. Material is various, mainly STKM-13CT ST52 CK45 and AISI 1020. We can also offer as customized seamless steel tube.
2.precision steel tubes
cold drawn steel tube/cold rolled steel pipe
Grade: 20#45#16Mn25Mn Q345 27SiMnE355ST52 STKM13A STKM13C
Standard: GB/T8713GB/T3639DIN2391EN10305ASTMA519
Range: 30-300mm
Length: 11m(max)
The cold process can remove the oxide layer outside to improve surface and offer better mechanical property, also can change ID,OD,WT to meet every client request.
3. Honed steel tube&SRB steel pipe
ID Tolerance: H8H9 or as client's request
ID Roughness: RA0.4micron(max)
Length: 6m(max)
Inner roughness: Ra0.2-0.8um
Straightness: 1:1000 or customized
This process can improve the roughness of the inner tube to 0.2-0.8um and make tube for cylinder using directly.
4.Hydraulic cylinder steel 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 2008; each tube of ours is strictly in quality control that can assure the product quality of Xinpeng.
