 The high-pressure boiler tubes is the kind of boiler tubes are seamless steel pipe category. Manufacturing methods and seamless pipe, but stringent requirements for manufacture of steel pipes used in the steel. High pressure boiler tube use, often in conditions of high temperature and high pressure pipe, the effect of high temperature flue gas and water vapor, oxidation and corrosion. Steel pipe with high rupture strength, high resistance to oxidative corrosion and have good organizational stability. High Pressure Boiler Tube is mainly used to manufacture high pressure and ultra-high pressure boiler superheater tubes, reheater tubes, windpipe, the main steam pipe. 
 High-pressure boiler tube use and classification 
 For low-pressure boiler (working pressure is generally not more than 5.88Mpa operating temperature below 450 ℃) of heating surface tubes; for high-pressure boiler (working pressure is generally more than 9.8Mpa, the working temperature of 450 ℃ ~ 650 ℃ room) heating surface tubes, economizer, superheater, reheater, the petrochemical industry pipe and so on. 
 High pressure boiler tube standard 
 - Chinese national standards (low and medium pressure boiler seamless steel tubes) 
 - China's national standard high-pressure boiler tube (high-pressure boiler seamless steel pipes) 
 Boiler tubes using steel 
 (1) high-quality carbon structural steel 
 (2) alloy structural steel 
 (3) rust heat-resistant steel boiler tubes to ensure the chemical composition and mechanical properties by the root, do the hydrostatic test, to make flaring, flattening test. Steel pipe to the heat treatment delivery. 
 In addition, the finished steel microstructure, grain size, decarburized layer have certain requirements. 
 Toxic trace elements As, Sn and Pb, and Bi oxygen potential is less than the oxygen potential of the Fe is completely left in the liquid steel in the steelmaking process. To control the toxic trace elements in the steel must be controlled from the source of the steelmaking charge 
 Year round with a variety of materials of high quality steel pipe, seamless steel pipe, seamless pipe, structural tubes, transmission fluid, low and medium pressure boiler pipe, high pressure pipes, high pressure boiler tubes, fluid tubes, petroleum cracking pipe, fertilizer dedicated pipe, all kinds of alloy tube. Lianxiao clad steel, steel, smelting steel, Anshan, Baoshan, Hengyang Steel, Tin steel and other brand-name manufacturers of seamless pipe. Through years of efforts, the company has become a domestic large-scale stainless steel tube, stainless steel plate, steel pipe, carbon steel pipe sales bases. Met with the major power plants, boiler plants, petroleum, chemical, mechanical expansion of the market, has established an extensive sales network, has a certain reputation. 
 The company abide by contractual commitments to product quality and services, and is willing to work with the new and old customers sincere cooperation, create a better future.
