Character

 

Honed steel pipe or SRB steel pipe are widely directly used for hydraylic cylinder, this kind pipe are in better internal roughness Ra 0.2~0.8um, ID tolerance: H8  H9, straightness:1:1000 or customized, length: Max 6m.  Strictly abide by ISO9001 system, our production are in high quality control with tight tolerance , better surface finishing, and superior mechanical property .

 Packaging&Shipping

1. bundle packing

2. marking as per customer's requests

3. paint on the pipe as per customer request

4. pipe caps as customer request

 Delivery condition

1. NBK(+N)

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
