High pressure boiler tube is among the boiler tube, from the the seamless steel tube kind. Production approaches and seamless tube would be the exact same, but have stringent request for making steel used in the steel. High pressure boiler tubes are frequently in high temperature and high-pressure conditions, when utilizing the conduit underneath the action of high temperature flue gas and water vapor, oxidization and corrosion will happen. Demands of steel conduit oxidation corrosion resistance that is high, with high rupture strength, and also have good organizational stability. High pressure boiler tube is mainly used to produce high-pressure and ultrahigh-pressure boiler superheater tubes, reheater tube including steam pipe. High pressure boiler tubes are often in high temperature and high-pressure conditions, when using the conduit beneath the action of high temperature flue gas and aqueous vapor, oxidation and corrosion will occur. Requirements of seamless steel pipe high oxidation corrosion resistance, with high rupture strength, and also have great organizational stability. High pressure boiler tube is especially used to make high pressure and ultra-high-strain boiler superheater tubes, reheater tube such as steam pipe. High-pressure boiler tubes depth that is apparent. Prevent high pressure boiler in the fire rapidly warming deformed slump, its steps are varied, the key will be to take an alternate strategy with respect to the circumstances, like the utilization of insulation, refractory steel barrier direct flame burning, reduce the speed of heat-transfer delayed metal temperature, strength becomes weak time. But regardless of what process adopted, the theory is the same. Fire retardant coating is a fireplace in recent years more sophisticated measures that are technical. Because of impurity elements have an effect on the grade of the high pressure boiler, elevated rates of damaging components in steel goods and inclusion of control has quite strict requirements, to strive various impurity elements are required to command at really low levels, frequently in creation using secondary refining the generation process in order to guard its cleanliness. First, high pressure boiler conduit installation is tough, especially in Supercritical no drum, raising heat conduit systems the starting system, stiff ray volume than normal essential boilers large, quantity, and all of the warming surface welding, installation difficult. Often in high pressure boiler tubes when when utilizing high temperature and pressure circumstances, the pipe underneath the action of high-temperature fuel and aqueous vapor, oxidisation and corrosion will occur. Boiler warming surface tubes working cooling conditions worsen, dry, so that the surprising increase in the temporary wall temperature, the temperature reaches a critical point (Ac1) above, a sharp decrease in the tensile strength of high-pressure boiler tube, pipe stress exceeds the yield limit, resulting in shear fracture and burst pipes, busted pipes called this short burst overtemperature.
