Product Description

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

hole of the hydraulic cylinder tube usually precision processed by boring,reaming,rolling or honing.By these process can ensure the piston,sealing elements and the support elements move smoothly,then ensure the sealing effect and reduce the abrasion.The hydraulic cylinder tube will bear big pressure,so need high strength and stiffness.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.

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

precision tube

Precision steel pipe is a kind of high precision steel tube material after 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 steel pipe, welded pipe

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

The honed tube belongs to the high precision steel pipe material, which has no oxidation layer, no leakage of pressure, high accuracy, high finish, no distortion of bending, expansion, and no crack.It mainly applies to machining.The car industry

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.

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.

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
