What is 15CrMoG threaded seamless boiler, high pressure boiler tube steel pipe Shaanxi, 15crmoG 15crmoG alloy tube alloy tube for low and medium pressure boiler (working pressure is generally not more than 5.88Mpa, working temperature below 450 ℃) of heating surface of the tube; for high-pressure boilers (above 9.8Mpa working pressure in general, the working temperature between 450 ℃ ~ 650 ℃) of heating surface tubes, economizer, superheater, reheater, petrochemical industrial pipe. 15crmoG alloy pipe is not a pipe, its performance is much higher than the average of seamless steel tubes, which contain Cr steel because it is more, its high temperature resistance, corrosion resistance is smaller than other seamless steel pipe, so alloy pipe in the petroleum, chemical, electric power, boiler and other industries more extensive use. 15CrMo steel is steel is widely used in the power industry, at 500 ℃ -550 ℃ use with high thermal strength properties. When the temperature is higher than 550 ℃ Guizhou steel pipe, significantly reducing its heat resistant properties. Typically 15CrMo steel is mainly used for high pressure piping steam parameters of 510 ℃, the steam conduit, the wall temperature of 550 ℃ heat pipe and so on. Similar foreign steel types, the former Soviet Union 15XM, US grade T12, P12, Japanese brands STBA22, STPA22 and Germany 13CrMo44 cards and so on. At present, China's large-diameter alloy steel pipe consumption accounts for half of the total proportion of developed countries only, alloy pipe expanding field of use to provide a broader space for development of the industry. According to the research branch of China Steel Association alloy tube, the future needs of the average annual growth of China's large-diameter alloy long steel pipe up to 10-12%. Shandong Liaocheng Polygram Pipe Manufacturing Co. provides you with Polygram Liaocheng Steel Pipe Manufacturing Co. teach you how to distinguish between true and false distinction between high-pressure boiler seamless steel pipe between the ordinary high-pressure seamless steel seamless pipe GB5310 high pressure boiler tube boiler tubes GB5310 Purpose: Suitable for high pressure with a 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 in Inner Mongolia is too large steel pipe, resulting in the ears, it creates a rolling when folded down, it will crack when folded products bending, the strength of steel big drop.
