Boiler pipe refers to the steel with open ends and hollow cross-section, and its length is larger than that of the surrounding. According to the production method, it can be divided into seamless steel pipe and welded steel pipe. The specifications of the steel pipe use external dimensions (such as outer diameter or side length) and Wall thickness means a wide range of sizes, from capillary tubes with a small diameter to large-diameter tubes with a diameter of several meters. Steel pipes can be used for pipelines, thermal equipment, machinery industry, petroleum geological exploration, containers, chemical industry and special purposes.
The boiler pipe is a kind of seamless tube. The manufacturing method is the same as that of seamless pipes, but there are strict requirements on the steel grades used to manufacture steel pipes. According to the operating temperature, it can be divided into general boiler tubes and high pressure boiler tubes.
The mechanical properties of the boiler tube is an important index to ensure the final use performance (mechanical properties) of the steel, and it depends on the chemical composition of the steel and the heat treatment system. In the steel pipe standard, according to different application requirements, the tensile properties (tensile strength, yield strength or yield point, elongation), hardness, toughness indexes, and high and low temperature properties required by users are specified.
1. General boiler tubes are mainly used to manufacture water wall tubes, boiling water tubes, superheated steam tubes, superheated steam tubes for locomotive boilers, large and small smoke tubes and arched brick tubes.
2. High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air guide tubes, main steam tubes, etc. of high-pressure and ultra-high-pressure boilers. The supply and demand trend of the high-pressure boiler tube industry is generally stable, but the supply and demand situation of each specific sub-industry will be further divided. Industry insiders pointed out that the most critical link is the use and promotion of new energy-saving insulation 20g high-pressure boiler tube equipment.
New energy-saving 20g high-pressure boiler pipe products are gradually increasing in the market, such as green paint, energy-saving water-saving sanitary products, environmentally friendly stone, environmentally friendly external cement foam insulation board, etc., energy-saving and environmentally friendly products in the broad market of 20g high-pressure boiler tube industry The prospects in China are promising.
