Main products

1 Hydraulic Cylinder Tube

Used in the hydraulic cylinder of the heavy machinery, Cranes, excavator also forklifts. We can work and get the mechanical property of the clients need.

2. SRB tube

Directly used in Elevatorbuffer and Hydraulic Cylinder .This kind tube have a better inner roughness , ra0.2-0.4um and can use directly in the hydraulic cylinder tube. Length can work at most 6M.

3. Cold finished tube

Widely Used. Processing range 30-300mm, biggest length is 11M.

 

 

The difference between precision steel pipe and seamless pipe?

 

1. the seamless steel tube with obvious difference is that dimensional accuracy, can be up to 0.1mm.

 

2. high precision steel pipe diameter surface finish, the customer without processing can be used directly and ordinary seamless steel tube to the customer and lather, polishing processing.

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

 

 

Application

widely used in hydraulic system with precision steel tube, injection molding machine with precision steel tube, hydraulic press with precision steel tube, shipbuilding with steel tube, EVA foaming, hydraulic machinery, hydraulic cutting machine, shoe making machinery, hydraulic equipment, high pressure tubing, hydraulic tubing, card sets of joints, pipe joints, rubber machinery, forging machinery, casting machinery, engineering machinery
