What is a boiler steel pipe?
Boiler steel tubes refer to steel materials that are open at both ends and have hollow sections with a large length relative to the surrounding area. According to the production method, they can be divided into seamless steel pipes and welded steel pipes. The specifications of the steel pipes are determined by the external dimensions (such as outer diameter or side length) and Wall thickness is expressed in a wide range of sizes, from capillary tubes with very small diameters to large diameter tubes with diameters of several meters. Steel pipes can be used in pipelines, thermal equipment, the machinery industry, petroleum geological exploration, containers, the chemical industry, and special purposes.
Applications of boiler steel pipes:
The pipes used in industrial boilers are mainly seamless steel pipes because the performance indicators of seamless steel pipes can fully meet the requirements of boiler applications. Although the cost is high, their safety and reliability are high. Welded steel pipes are generally used as low-pressure fluid transportation pipes within 2Mpa. High-temperature and high-pressure equipment such as industrial boilers must use seamless steel pipes, and the thickness of the pipe wall is correspondingly thickened. Welded steel pipes are now also used in medium and low-pressure boilers, thanks to the rapid improvement of welding technology. For example, when pipes are butt-welded to friction-welded steel pipes, the microstructure of the joints is no different. Moreover, after the pipe seams are remelted through butt joints and corner joints, it is difficult to observe the seam marks with the naked eye. The microstructure of its parts has become the same as that of friction-welded steel pipes. It’s the same as at the seam.
