Boiler steel pipe refers to the two ends of the open and has a hollow section, the length and the surrounding relatively large steel, according to the production method can be divided into seamless steel pipe and welded steel pipe, boiler 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. Steel pipes can be used in pipelines, thermal equipment, machinery industry, petroleum geological exploration, containers, chemical industry and special purposes.

PRODUCT PARAMETER

Boiler steel pipe is a kind of seamless pipe. 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 steel 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.

1. Overview

(1) Manufacturing method:

① The general boiler tube temperature is below 450℃, and the domestic pipe is mainly made of No. 10, No. 20 carbon-bound steel hot-rolled pipe or cold-drawn pipe.

When the high-pressure boiler steel pipe is used, it is often under high temperature and high pressure conditions, and the pipe will oxidize and corrode under the action of high temperature flue gas and water vapor. The steel pipe is required to have high durable strength, high oxidation corrosion resistance, and good organizational stability.

(2) Use:

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.
