Long-pressure boiler tubes for precision steel plant transformation grab market opportunities. October 2014, Babcock & Wilcox Company formally Polygram Liaocheng Steel Pipe Manufacturing Co. ordered within a length of 14 to 18.3 m long threaded pipe of 217 tons for the supercritical boiler manufacturing plant. 2008, I plant high-pressure boiler tube long tube production to achieve a length of steel two major shift production from only 12-16 meters in length carbon steel pipe, into the energy production of 21.5 m long threaded alloy steel, and has successfully developed a series of products, domestic and foreign user's attention and affirmation stainless steel pipe specifications, continue to lead the female domestic production operations. In March 2009, through the optimization of cold drawing dies improvement and pickling, lubrication, heat treatment and other supporting technology, as well as the ability to improve equipment, precision steel pipe production plant long has been extended eight grades, the maximum length of 22.51 m. At the same time, carry out research and application of long tube to pull within a molding of new materials, so that the service life of the ordinary in the mold of 8 times. In 2009, Babcock & Wilcox Company won the bid Vietnam Weng shore boiler plant 600,000 kilowatts 304 stainless steel prices, Liaocheng, Shandong Steel Pipe Manufacturing Co., Polygram provide long pipe for the project has played an important role in the final production. At present, Shandong Liaocheng Polygram Pipe Manufacturing Co. to produce 24 m long tube T91, T22 high-grade steel products, products exported to many countries, Russia, South Korea, India and other stainless steel tube, the praise of users. Ten thousand tons of cash, instant ordering, free delivery, with the original materials and third-party inspection reports elemental analysis, quality assurance. Liaocheng in Shandong Steel Pipe Manufacturing Co., Polygram to ensure the best quality, the fastest speed to the customer, the customer will not delay required! Welcome to order! Seamless operated varieties, superior quality 304 stainless steel tube reasonable price point was designated as the China Petrochemical distribution units, sales center in North China and domestic specialty steel seamless pipe Standard: 1. Structural seamless ( GB / T8162-2008) is used for seamless general structural and mechanical structure. 2 fluid seamless pipe (GB / T8163-2008) is generally seamless pipe used for conveying water, oil, gas and other fluids. 3. The low-pressure boiler seamless pipe (GB3087-2008) is used in the manufacture of various structural low and medium pressure boiler superheated steam pipes, boiling water pipes and superheated steam locomotive boiler tubes, opium pipe, small pipe and brick arch effective high-quality carbon structural steel hot-rolled and cold drawn (rolled) seamless. 4. The high-pressure boiler quality carbon steel seamless pipe (GB5310-2008) is used to manufacture high-pressure and more pressure water tube boiler heating surface with steel, alloy steel and heat-resistant stainless steel seamless pipe. 5. fertilizer equipment, high pressure seamless pipe (GB6479-2000) is applicable to operating temperature -40 ~ 400 ℃, working pressure of high-quality carbon structural steel and alloy steel 10 ~ 30Ma of chemical equipment and piping seamless. Liaocheng in Shandong Steel Pipe Manufacturing Co., Polygram teach you how to distinguish between true and false distinction between the ordinary high-pressure boiler seamless steel pipe and seamless pipe GB5310 between high pressure boiler seamless steel pipe GB5310 high pressure boiler tube Uses: Suitable for high pressure The minimum wall thickness of Seamless Carbon Steel Boiler and Superheater pipe. GB5310 seamless steel Dimension Tolerance: Type diameter pipe (D) wall thickness (S) diameter size (mm) tolerance (mm) diameter size (mm) tolerance (mm) hot-rolled tubes ≤101.6 + 0.4 ~ - 0.876 ~ 168.3 + 28% ~ 0> 101.6 ~ 168.3 + 0.4 -1.2 drawn tube <25.4 + 0.10≤38.1 + 20% ~ 025.4 ~ 38.1 + 0.15> 38.1 ~ <50.8 + 0.20> 38.1 + 22% ~ 0 Ordinary fluid seamless steel material containing impurities, the density of steel is small, and the size tolerance serious, so in the absence of a vernier caliper case, you can check it weighed. No ordinary seamless steel metallic luster, pale red or similar color pig iron, ordinary and small factories producing seamless seamless rolling temperature is not standard, they are visually steel temperature, so can not be prescribed normalizing temperature, the natural properties of the steel can not meet the strength requirements of the country, shoddy seamless steel prone to folding. Folding is formed on the surface of a variety of seamless fold, this defect often throughout the product vertical. The reason is due to shoddy manufacturers of folding the pursuit of high efficiency, reduction is too large, resulting in the ears, it creates a rolling when folded down, it will crack when folded products bending, the strength of steel big drop.
