High pressure boiler tube is among the boiler tube, belonging to the seamless steel tube kind. Seamless tube and manufacturing procedures will be exactly the same, but have strict request for fabricating steel utilized in the steel. High pressure boiler tubes are frequently in high pressure conditions and high temperature, when utilizing the pipe underneath the action of water vapor and high-temperature flue gas, oxidisation and corrosion may happen. Necessities of steel pipe high oxidation corrosion resistance, with high rupture strength, and have good organizational stability. High pressure boiler tube is principally used to make high-stress and ultrahigh-strain boiler superheater tubes, reheater tube such as steam pipe. High pressure boiler tubes are generally in high-pressure conditions and heat, when utilizing the pipe below the action of high temperature flue gas and water vapor, oxidization and corrosion will happen. Prerequisites of seamless metal pipe with large rupture strength, high oxidation corrosion resistance, and have good organizational stability. High pressure boiler tube is mainly used to produce high pressure and ultra-high-strain boiler superheater tubes, reheater tube, airway, like steam pipe. High-pressure boiler tubes apparent depth. Change the results of unsaturated resin; chlorinated unsaturated polyester resin having a high amount of firmness, excellent high temperature oxidizing acids and damp chlorine and other oxidizing medium, outstanding resistance to chlorine remedy medium and heat-resistance, higher order under pressure to work with, often regarded heating surface tube design is quite thick. Depth of the high-pressure boiler tubes shan't exceed the nominal wall thickness of the unfavorable prejudice, its clean up of the particular wall thickness of the wall thickness shall not be less compared to the minimum enabled. Prevent high-pressure boiler in the fire quickly warming deformed slump, its actions are varied, the important thing would be to take a different strategy depending on the circumstances, such as the utilization of insulation, refractory steel impediment direct flame burning, decrease the rate of heat transfer delayed metal temperature, power becomes feeble time. But regardless of what method adopted, the theory is exactly the same. Due to impurity components have an effect on the quality of the high pressure boiler, elevated levels of damaging elements in steel products and inclusion of control has very strict requirements, to attempt different impurity elements must control at really low levels, frequently in production using secondary refining the production process as a way to safeguard its cleanliness. First, high pressure boiler conduit installation is tough, particularly in Supercritical no drum, raising heat pipe systems the starting method, rigid beam volume than standard essential boilers substantial, measure, and each of the heating surface welding, installation hard. Commonly in high pressure boiler tubes when using the conduit beneath the action of high temperature fuel and water vapor, heat and pressure conditions, oxidization and corrosion will happen.
