Company Pipe: the most homogeneous specifications, the lowest price, best quality, best service! We welcome new and old customers to guide our company to negotiate business Liaocheng Polygram Pipe Co., Ltd. is a company specializing in special steel, special-purpose steel research and development, production and sales of large enterprises. Since inception, we have to quality services, professional quality inspection personnel, equipment to ensure the sales of each product to achieve customer satisfaction Yiyang small diameter seamless, access to many users. Shandong Liaocheng Polygram has focused on forging steel pipe, automotive structural pipe, oil well pipes, oil and gas pipelines, chemical industry, marine, boiler, nuclear power and other special pipe. Implementation of the standards are the national standard, Japanese standard, German standard, the British standard, American standard. Our products have been widely used in the hydraulic system piping, automobile manufacturing pipes, industry, construction machinery, railway locomotive, aerospace, shipbuilding, injection molding machines, die casting, machine tool, diesel, petrochemical, power plants, boiler equipment and other industries. Shandong Liaocheng Polygram steel annual sales of Chengdu Iron and Steel Group, Daye Steel Group, Baotou Steel, Baosteel Group, Anshan Iron and Steel Group, Tianjin Seamless, Xining Te steel, Wuxi Steel Plant, Hengyang Steel Plant and other major steel production all kinds of seamless steel and alloy tubes. It has formed the annual inventory turnover of more than 15,000 tons of Small-caliber seamless steel pipe, the annual sales volume of over billion. Precision stainless steel pipes and industrial grade stainless steel seamless pipe can be compared to 1 in the following aspects, industrial grade stainless steel tube material is stainless steel tube, which Huaihua shortage of small diameter seamless steel pipe, cold drawn or cold rolled after annealing and pickling It is finished stainless steel seamless pipe. The main features of industrial grade stainless steel seamless pipe is without welding seam, can withstand greater pressure, but through solid steel surface melting process (that is, we usually say that the annealing treatment) pipe can be bent, reaming and other processing. 2, precision stainless steel tube products emerged in recent years, mainly in the hole, the outer dimensions with tight tolerances, surface finish and steel have high demands. Precision stainless steel tube 1. The outer diameter of the smaller features, in general, precision stainless steel tube outer diameter of 6 mm or more in general, Wenzhou Renault tube can produce diameter 6-133 mm steel pipe. High precision can do small batch production, I plant the production of precision stainless steel tube finishing MOQ is 500KG, and special sizes and requirements can also be customized, the production of precision stainless steel pipe to meet the special requirements of different users. 3. Accuracy of relatively high precision stainless steel pipe, steel pipe and the bore diameter tolerance 6-60 of the general control within plus or minus 3-5 silk. 4. surface finish good precision stainless steel tube, inside and outside surfaces of the tube finish Ra≤0.8μm, can make to the wall thickness of 0.5mm. Then polished inner and outer surfaces of the tube finish up Ra≤0.2-0.4μm (such as a mirror). 5. The small diameter seamless steel pipe superior performance, the metal is relatively dense, steel pipe can withstand the pressure becomes larger. In short: precision stainless steel tube is for further processing in the general industrial grade stainless steel tube, precision and smoothness in the obvious strengths, but its cost is relatively teach high, high-end stainless steel tube. 20 # small diameter seamless steel pipe, small diameter seamless Changsha, small diameter seamless steel pipe provided by the Shandong Liaocheng Steel Pipe Manufacturing Co. Polygram. Liaocheng in Shandong Steel Pipe Manufacturing Co. Polygram (www.lcbljgg.com) (www.lcbljgg.com) (www.sdlcblj.com) (www.bljggzz.com) to provide "seamless Changsha, Hunan seamless Hunan low-pressure boiler tubes, Hunan alloy tube "and other business, the company has" Baosteel, Baotou, Tianjin Seamless, Chengdu "and other brands.
