what is a high-pressure boiler tube?

High-pressure boiler tubes belong to the category of seamless steel pipes, such as seamless carbon steel boiler tubes, which have very high requirements on the tightness of the steel pipes. The method of production is the same as that of seamless tubes, and the requirements are basically the same. However, the requirements for high-pressure boiler tubes are It is more demanding than ordinary boiler tubes. Because high-pressure boilers often operate in high-temperature and high-pressure environments, ordinary steel pipes cannot meet the operating requirements. This is one of the major reasons why special boiler tubes for high-pressure boiler tubes were born.

High-pressure boiler tubes not only require high temperature and high pressure resistance, but also require high-pressure boiler tubes to have good anti-corrosion and oxidation resistance. Because high-pressure boilers often come in contact with corrosive liquids, ordinary steel and more corrosive liquids or water and steam will have a certain degree of oxidation and corrosion, which consumes very high materials. In order to reduce the cost of building materials, Generally, when selecting materials at the beginning, they are more inclined to choose anti-corrosion and anti-oxidation materials. The rigidity and elasticity requirements of the product are very high, because this type of instrument often produces great vibration and impact during work, and ordinary steel pipes cannot meet the requirements of the operation.

High-pressure boiler tubes have a wide range of uses. They are mainly used in the manufacture of water-cooled wall tubes and steam tubes with excessively high temperature. High-pressure boiler tubes must be used for parts with excessively high temperatures such as engines in motor vehicles. Overheated steam and liquid will have certain effects on ordinary pipes. In addition, high-pressure boiler tubes are often used to make ducts and air ducts in high-pressure and ultra-high-pressure boilers, which have very good heat and gas conduction effects. The hardness of the high-pressure boiler tube is also very strong, and it is often used in the environment of industrial testing.
