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.
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.
