High precision DIN2391 series hydraulic seamless steel tube

　　The distinctive features of high precision DIN291 series hydraulic seamless steel tube is high precision, high finish. Due to the use of special without oxidation bright heat treatment process NBK, steel tube inside and outside the wall does not produce oxide layer after heat treatment, steel pipe, high cleanness of the outer wall; Excellent mechanical performance of steel tube, steel tube can be used in a variety of environments without leaking under high pressure and cold bending deformation, flaring, flattening without cracks.

　　On the dimensional accuracy and surface roughness index than the German DIN standard, European EN standards and the United States ASTM standard series, product quality can be equivalent to that of Germany, Sweden, similar products.At present has formed a series of DIN, EN series high precision precision seamless steel tube, precision steel tube, EP grade stainless steel tube, double roll tube welding four big series products.

　　We have adopted advanced production equipment and technologies to manufacture our fluid pipe and line pipe, which can not only improve product quality, but also save raw materials. Our products have high strength, good toughness and resistance to corrosion.

　　With standard import steel tube and steel tube has been widely substitute used in hydraulic system piping, automobile manufacture piping, military industry, engineering machinery, railway locomotive, aerospace, shipbuilding, injection molding machine, die-casting machine, machine tools, diesel engine, oil chemical industry, power plant, boiler equipment and so on all walks of life, won praise users.
