Product Description
Boiler tube identifies a steel with open ends and a hollow section, and its length is bigger than that of its environment. According to the manufacturing process, it may be divided into seamless steel pipes and welded steel pipes. The specifications of the steel pipes utilize external dimensions (like outer diameter or side length) and Wall thickness signifies a broad assortment of measurements, from capillary tubes with a small diameter to large-diameter tubes with a diameter of several meters. Steel pipes may be used for pipelines, thermal equipment, machinery industry, petroleum geological exploration, containers, chemical industry and specific functions.

Production Process and Feature
The boiler tube is a type of seamless tube. The manufacturing method is just like that of seamless pipes, but there are stringent requirements on the steel grades used in the production of steel pipes. According to the operating temperature, it may be divided into general boiler tubes and high-pressure boiler tubes.
The mechanical components of the boiler tube is an important index to guarantee the last usage performance (mechanical properties) of the steel, and it is based upon the chemical composition of the steel and the heat treatment system. From the steel pipe standard, based on different application requirements, the electrical properties (tensile strength, yield strength or yield point, elongation), hardness, toughness indicators, and low and high temperature properties demanded by users are defined.
Application
①General boiler tubes are mainly used to create water wall tubes, boiling water tubes, superheated steam tubes, superheated steam tubes for locomotive boilers, big and little smoke tubes and arched brick tubes.
②High-pressure boiler tubes are mainly used to manufacture superheater tubes, heater tubes, air guide tubes, main steam tubes, etc. . high-pressure and ultra-high-pressure boilers. The supply and demand tendency of the high-pressure boiler tube business are generally secure, but the supply and demand situation of each particular sub-industry will be further split. Industry insiders pointed out that the most crucial link is the use and marketing of new energy-saving insulation 20g high-pressure boiler tubing equipment.
