Boiler pipe is a kind of steel with hollow section and open at both ends. Its length is larger than the surrounding steel. According to the production method, it can be divided into seamless steel tube and welded steel tube. The caliber tube. Steel pipes can be used for pipelines, thermal equipment, machinery industry, petroleum geological exploration, containers, chemical industry and special purposes.
Boiler pipe is one kind of seamless pipe. The manufacturing method is the same as seamless pipe, but there are strict requirements for the steel used for manufacturing the steel pipe. According to the use of temperature, it can be divided into two types: general boiler pipe and high pressure boiler pipe.
The mechanical property of boiler pipe is an important index to ensure the ultimate performance of steel, which depends on the chemical composition of steel and heat treatment system. In the steel pipe standard, according to different use requirements, the tensile properties (tensile strength, yield strength or yield point, elongation) as well as the hardness and toughness indicators, as well as the high and low temperature performance required by users are stipulated.
