Tianjin No. 45 seamless pipes seamless pipes factory in Wuxi No. 45 No. 45 thick-walled seamless steel higher strength than the 15th, rarely quenching, no temper brittleness. Cold deformation on the crack-prone high plasticity, usually for bending, welding performance rolling, curved edges and hammer arch processing, arc welding and contact welding, gas welding small thickness, shape requires strict or complex shape parts. Machinability drawn or normalizing state than the annealed condition is good, generally used for manufacturing large discontinuity toughness requirements. Advanced production and testing equipment is necessary to ensure manufacturing quality precision seamless steel tubes, the company attaches great importance to the modernization of production equipment to ensure the leading level in the industry. Using advanced technology to produce seamless cold-rolled production equipment, high precision mill, producing a wide range of standard models and flexible, more advanced than the general automatic cold rolling units, while the configuration of advanced automation and control systems and on-line quality inspection system. Ensure stable and reliable product quality. Our production of precision seamless bright bright color system looks smooth, uniform thickness, no oxide layer, high precision. Seamless inner hole can be divided into round, spline type, plum-type and other widely used in automobiles, motorcycles, hydraulic, petrochemical, shipbuilding, aerospace, bearings, pneumatic components, fuel tanks, boiler equipment, medical equipment, fitness equipment and other industries . Pipe Category: 20 # high precision seamless, precision steel 45 #, GCr15 bearing steel, 20Cr precision steel, 16Mn seamless steel, 40Cr steel and other precision tubing and casing. Non-standard precision tubes can be customized according to user needs.
