1.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.

2.Hydraulic Tube Material
JIS STKM13C, DIN ST52, SAE1020 or Mechanical Construction Use Carbon Steel Pipes, Other Specifications Can be made Customer Request based on.

Our Workshop

Our Company is equipped with JLB250T hydraulic cold drawn machine set,LD120 precision cold rolled machine set, multiple precision straightening machine,box heat treat furnaces(8000-10000mm), advanced CNC skived and roller burnished machine SRB-6000mm, several powerful honed machine, combined cold drawn, cold rolling, heat treatment, and SRB process to produce the best quality products.

Product Process

Our Products

Honing tube and rolling tube inside and outside wall oxide layer, to withstand high pressure without leakage, high-precision, high-quality finish, cold deformation, flaring, flattening without cracks a bit, so mainly used to produce pneumatic or hydraulic components products, such as cylinder or cylinders, which can be seamless. Chemical composition of two kinds of materials are C, Si, Mn , S, P, Cr. Relatively speaking rolling tube better than honing tube good.

Application

Hydraulic cylinder tube st52 din2391 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, automotive high pressure steel pipe concrete pump, sanitation vehicle, automobile industry, shipbuilding industry, metal processing, military industry, diesel engine, the internal combustion engine, air compressor, construction machinery, forestrymachinery, etc.
