What is High-Pressure Boiler Tube

High-pressure boiler tubes belong to the category of seamless steel tubes, such as seamless carbon steel boiler tubes, which have very high requirements for the sealing of steel tubes. The production method is the same as seamless tube and the requirements are basically the same. However, the requirements of high-pressure boiler tubes are more demanding than those of ordinary boiler tubes. Since high-pressure boilers are often operated in high-temperature and high-pressure environments, ordinary steel tubes cannot meet the operational requirements. This is one of the main reasons for the birth of special boiler tubes for high pressure boiler tubes.

High-pressure boiler tube is not only required to resist high temperature and high pressure, but also requires high-pressure boiler tube with good corrosion and oxidation resistance. As high-pressure boilers are often in contact with corrosive liquids, ordinary steel and corrosive liquids or water, steam will produce a certain degree of oxidative corrosion, material consumption is very high. In order to reduce the cost of construction materials, generally at the beginning of the selection of materials, more inclined to choose corrosion, oxidation-resistant materials. The rigidity and elasticity of the products are required to be very high, because these instruments often produce great vibration and shock when working, and ordinary steel pipes cannot meet the requirements of operation.

High pressure boiler tubes have a wide range of applications. They are mainly used for the manufacture of water-cooled wall tubes and excessively hot steam tubes. High-pressure boiler tubes must be used for components with excessive temperatures, such as the engines of motor vehicles. Excessively hot vapors and liquids can have an effect on ordinary pipes. In addition, high pressure boiler tubes are commonly used to make air ducts and ducts in high pressure and ultra high pressure boilers, which have very good heat and air conductivity. High-pressure boiler tubes are also very hard and are commonly used in industrial testing environments.
