high press boiler tube

Boiler tube is a kind of seamless tube manufacturing methods and seamless tube are the same, but the grade of steel used in the manufacturing steel pipe have strict requirements According to the use of temperature can be divided into general boiler tube and high pressure boiler tube, the mechanical properties of two kinds of boiler tube steel is eventually use (mechanical properties) of the important performance indicators, it depends on the chemical composition of the steel and heat treatment system In the steel pipe standard, according to different use requirements, stipulated the tensile properties (tensile strength yield strength or yield point elongation) and hardness and toughness indicators, as well as user requirements of high and low temperature performance.
