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 performance of the steel tubes. The production method is the same as that of seamless pipes, and the requirements are basically the same. However, the requirements for high-pressure boiler tubes are more stringent than ordinary boiler tubes. Since high-pressure boilers often operate in high-temperature and high-pressure environments, ordinary steel pipes cannot meet operating requirements. This is one of the main reasons for the birth of special boiler tubes for high-pressure boiler tubes.

High-pressure boiler tubes are not only required to be resistant to high temperature and high pressure, but also have good anti-corrosion and anti-oxidation properties. Since high-pressure boilers are often in contact with corrosive liquids, ordinary steel and more corrosive liquids or water or steam will produce a certain degree of oxidative corrosion, resulting in very high material consumption. In order to reduce the cost of building materials, anti-corrosion and anti-oxidation materials are generally preferred when selecting materials. The rigidity and elasticity requirements of the product are very high, because such instruments often produce large vibrations and impacts during operation, and ordinary steel pipes cannot meet the operational requirements.

High pressure boiler tubes have a wide range of uses. Mainly used for manufacturing water-cooled wall pipes and steam pipes with excessive temperatures. High-pressure boiler tubes must be used in parts where temperatures are too high, such as motor vehicle engines. Superheated steam and liquids will have certain effects on ordinary pipes. In addition, high-pressure boiler tubes are often used to make air ducts and air ducts in high-pressure and ultra-high-pressure boilers, and have very good heat and gas conduction effects. High-pressure boiler tubes are also very hard and are often used in industrial testing environments.
