What Are 20G High Pressure Boiler Tubes?
Many of the high-quality 20G high-pressure boilers in the city use a lot of high-quality carbon steel. It can effectively improve the mechanical properties of steel, so that its energy consumption is very low and its service life is very long. High pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air ducts and main steam pipes of high-pressure and ultra-high-pressure boilers.
20G high pressure boiler tube is a kind of seamless tube. The manufacturing method is the same as that of seamless pipe, but there are strict requirements for the steel grade used in the manufacture of steel pipe. According to the temperature, it can be divided into general boiler tube and high pressure boiler tube. 20G high-pressure boiler tubes are often used in high temperature and high pressure conditions. Under the action of high-temperature flue gas and water vapor, the tubes will be oxidized and corroded. The steel pipe should have high endurance strength, high oxidation resistance and corrosion resistance, and good structure stability. Then the following small series for you is about the 20G high pressure boiler tube related information.

High pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air ducts and main steam pipes of high-pressure and ultra-high-pressure boilers.
20G high pressure boiler tube is made of steel for pressure parts of boiler, which is usually used in boilers below 39 kg. The heating surface tube is often designed to be very thick. 16Mng can be used under high pressure. 16Mng is widely used in order to reduce thermal resistance, save steel, ensure the safety of high, high pressure boiler steel, and reduce the amount of steel. At the same time, there are also special steels added with rare earth, magnesium, other metal and non-metallic materials. It will improve the performance of boiler steel, reduce the consumption of steel and thermal resistance.
1. Overview
(1) Manufacturing method:
① Generally, the service temperature of boiler tubes is below 450 ℃, and the domestic tubes are mainly made of 10 and 20 carbon steel hot rolled or cold drawn tubes.
② High pressure boiler tubes are often in high temperature and high pressure conditions when they are used. Under the action of high temperature flue gas and steam, oxidation and corrosion will occur. The steel pipe needs high endurance strength, high oxidation resistance and corrosion resistance, and good structure stability.
(2) Application:
① General boiler tubes are mainly used to make water wall tubes, boiling water tubes, superheated steam tubes, superheated steam tubes for locomotive boilers, large and small smoke tubes, arch brick tubes, etc.
② High pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air ducts and main steam pipes of high-pressure and ultra-high-pressure boilers.
2. Types
According to their high-temperature performance, boiler tubes are divided into general boiler tubes and high-pressure boiler tubes. Both general boiler tube and high pressure boiler tube, they can be divided into various kinds of steel pipe according to different application requirements.
