Boiler steel pipe  

Boiler tube is a kind of steel with hollow section and openings at both ends. It can be divided into seamless steel pipe and welded steel pipe according to the production method. The specification of steel pipe is expressed by its shape size (such as outer diameter or side length) and wall thickness. Its size range is very wide, ranging from small capillary pipe to large diameter pipe up to several meters. Steel pipes can be used in pipelines, thermal equipment, machinery industry, petroleum geological exploration, containers, chemical industry and special uses.
