Boiler Tube introduction

Boiler tube refers to the two ends of the open and has a hollow section, the length and the surrounding of the relatively large steel, according to the production method can be divided into seamless steel pipe and welded steel pipe, steel pipe specifications with external dimensions (such as outer diameter or side length) and wall thickness, its size range is very wide, from a small diameter of the capillary tube to a diameter of several meters of large diameter pipe.

Production method
Boiler tube is a kind of seamless tube. The manufacturing method is the same as seamless pipe, but there are strict requirements for the steel used in the manufacture of steel pipes. According to the use of temperature is divided into general boiler tube and high pressure boiler tube two kinds.
The mechanical properties of boiler tubes are important indicators to ensure the final service performance of steel (mechanical properties), which depends on the chemical composition of steel and heat treatment system. In the steel pipe standard, according to different requirements, tensile properties (tensile strength, yield strength or yield point, elongation) and hardness, toughness indicators, as well as high and low temperature properties required by users.

Purpose
① General boiler tubes are mainly used to manufacture water wall tubes, boiling water pipes, superheated steam pipes, superheated steam pipes for locomotive boilers, large and small smoke pipes and arch brick pipes.

② High-pressure boiler tube is mainly used to manufacture superheater tube, reheater tube, airway, main steam tube, etc., of high-pressure and ultra-high-pressure boilers. The supply and demand trend of the high-pressure boiler tube industry is generally stable, but the supply and demand situation of each specific sub-industry will be further differentiated.
