Boiler Tube open at both ends and has a hollow section, its length with the surrounding steel production methods can be divided into a seamless and welded steel pipe, steel pipe specifications Dimensions (such as outside diameter or side length) andwall thickness, said the size of a very wide range, from a very small diameter capillary tube until the diameter of a few meters of large diameter.
Boiler Tube use
1, Boiler Tube is mainly used to manufacture water wall tubes, tubes in boiling water and superheated steam pipe, superheated steam locomotive boiler tubes, large and small smoke pipe, and arched brick pipe.
2, high-pressure Boiler Tube is mainly used to manufacture high pressure and ultra-high pressure boiler superheater tubes, reheater tubes, airway, the main steam pipe.
Boiler Tube production methods
Boiler Tube is a kind of seamless pipe. Manufacturing methods and seamless pipe, but stringent requirements for manufacture of steel pipes used in the steel. According to the temperature level is divided into the two kinds of general Boiler of Tube and High Pressure Boiler of Tube.
The mechanical properties of steel is to ensure that an important indicator of the steel end-use properties (mechanical properties), it depends on the chemical composition and heat treatment of steel. Steel standards, according to different requirements, the provisions of the tensile properties (tensile strength, yield strength or yield point elongation) and hardness, toughness, user requirements, high and low temperature performance.
