Boiler steel pipe refers to a steel product with openings at both ends and a hollow section, and the ratio of its length to the surrounding area is large. According to the production method, it can be divided into seamless pipes and welded steel pipes. The specifications of boiler steel pipes are represented by external dimensions (such as outer diameter or side length) and wall thickness, and their size ranges from a small capillary tube to a large diameter tube with a diameter of several meters. Steel pipes can be used in pipelines, thermal equipment, machinery industry, petroleum geological exploration, containers, chemical industry and special purposes.
1. Manufacturing method of boiler tube:
① Generally, boiler tubes are used at a temperature below 450°C and are made of carbon steel hot-rolled or cold-drawn tubes.
②High-pressure boiler steel pipes are often under high temperature and high pressure conditions during use, and the pipes will be oxidized and corroded under the action of high-temperature flue gas and water vapor. Steel pipes are required to have high durable strength, high resistance to oxidation and corrosion, and good structural stability.
2. The purpose of the boiler tube:
①General 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 arch brick tubes, etc.
②High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, gas guide tubes, main steam tubes, etc. of high-pressure and ultra-high pressure boilers.
3. Types of boiler tubes
Boiler steel tubes are divided into general boiler tubes and high-pressure boiler tubes according to their high temperature performance. Regardless of general boiler tubes or high-pressure boiler tubes, they can be divided into various steel tubes according to their application requirements.
