Polygram perennial sales agent in Shandong, Cheng Gang, Steel, Bao, saddle, Ye, day, Hengyang Steel and other major steel production plants: 10 #, 20 #, 45 #, 16Mn, Q345B , 27SiMn, 40Cr, 20Cr, 20CrMo, 35CrMo, 42crmo, 20crmnTi, 15crmo, 12Cr1MoV, 10CrMo910, T91, P91 and other materials seamless steel pipe, high pressure boiler pipe, oil cracking pipe, imported alloy pipe, bearing steel and long-term sales various profiles beam, angle, H steel, channel, such as sheet metal;; various Q235B, Q345B and other welded pipe, spiral pipe and geology, pipelines, chemical, power and other special pipe all products in strict accordance with the national standard, the absolute guarantee quality, may enter into contracts for the supply pipe 60 * 4, is definitely your first choice for purchasing steel. Hot-rolled (extruded seamless pipe) production technology round tube → heating → perforation → three-roll rolling, rolling or extrusion → → set off pipe diameter (or reducing) → cooling → straightening → hydrostatic test ( or testing) → mark → storage seamless steel ingot is made of perforated or solid through the capillary tube, and then by the hot-rolled, cold-rolled or cold call is made. Seamless steel pipe wall thickness mm diameter * number indicates. Hot-rolled and cold-rolled seamless steel pipe points (written) seamless steel categories. Hot-rolled seamless steel pipe generally sub, low, medium pressure boiler pipe, high pressure boiler pipe, steel pipe, stainless steel pipe, oil cracking pipe, steel and other steel and other geological. Hot-rolled seamless pipe diameter is generally greater than 32mm, wall thickness 2.5-200mm, cold-rolled seamless steel pipe at the path can go to 6mm, wall thickness can be 0.25mm, outer diameter thin-walled tube to 5mm thickness can be less than 0.25mm, cold than hot-rolled high dimensional accuracy. Seamless is 10,20,30,35,45 and other high quality carbon steel 16Mn, 5MnV low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2,40MnB and other structural steel hot-rolled or cold-rolled steel. 10,20 and other low-carbon steel seamless pipe is mainly used for fluid pipes. 45,40Cr etc. made of carbon steel seamless pipe used to manufacture mechanical parts, such as cars, tractors and the force components. General seamless steel pipes to ensure the strength and flattening test. Hot-rolled steel hot-rolled state or heat treatment delivery; hot-rolled steel, by definition, high temperature rolling, so the deformation resistance, can achieve a large deformation. The steel rolling, for example, generally slab thickness of about 230mm 8 * 1 pipe, and after a rough rolling and finish rolling, the final thickness of 1 ~ 20mm. Meanwhile, the small plate thickness ratio, size, relatively low accuracy, flatness problem is not prone to control the convexity-based. 12 * 2 * 1 steel _10 _ steel pipe provided by the Shandong Liaocheng Steel Pipe Manufacturing Co.
