En10305-1 E355+SR Hydraulic Cylinder honed Seamless steel pipe

Hydraulic Cylinder Tube---The hydraulic cylinder tube is the main part of the hydraulic cylinder.The inner 

our precision tube ,honed tube ,SRB tube all can be used for hydraulic cylinder tube .

High precision steel tube high dimensional accuracy, tube inside and outside surface finish, steel after heat treatment without oxidation film, both internal and external surface steel tube flaring, flattening without cracks, cold bending deformation, and can bear high pressure, can make all kinds of complex deformation and mechanical processing processing.
The difference is:
The main characteristic of seamless steel pipe is no welding seam, which can withstand greater pressure.The product can be a very rough cast or cold dial.
Precision steel pipe is a product that has appeared in recent years. It is mainly the inner and outer wall dimensions with strict tolerance and roughness.

Honed tube is a kind of high precision steel tube material which is processed by cold drawing or hot rolling.Because of the precision steel tube inside and outside wall without oxidation layer, under high pressure without leakage, high precision, high finish, cold bending deformation, flaring, flattening without cracks etc, it is mainly used to produce pneumatic or hydraulic components products, such as a cylinder or cylinder, can be a seamless tube.The chemical constituents of quilted tubes are carbon C, Si, Mn, sulfur S, P and Cr.

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 stess relief after cold forming, heat treatment, steel pipe can be carried out within a certain limit in the appropriate processing again
