Product description
Seamless steel tube, made of whole metal, without seams, so called seamless steel tube.According to the production method, seamless tube divided hot rolled tube, cold rolled tube, cold drawing tube, extruded tube, top tube, etc .Our product is cold rolled or cold drawing then honed or SRB(skived rolled burnished) ,the surface polished some lathed.
Seamless steel pipe is mainly used for petroleum geological drilling pipe, petroleum chemical cracking pipe, boiler tube, bearing tube and automobile, tractor and aviation with high precision structural steel pipe.

Delivery condition of hydraulic cylinder tube
|
1.NBK(+N) of hydraulic tube
after cold forming, eventually above phase transition point, in a protective atmosphere of annealing oxidation medium
|
2. GBK(+A) of hydraulic cylinder tube
after cold forming, annealing in non oxidizing medium protective gas
|
3. BK(+C) of honed tube
the final heat treatment after cold forming, therefore small steel pipe plastically, the plastically degree does not guarantee
|
| 4. BKW(+LC) of hydraulic cylinder tube
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 honed tube
have a stress relief after cold forming, heat treatment, steel pipe can be carried out within a certain limit in the appropriate processing again
