How to select the steel material of industrial boiler

Industrial boiler is made of steel and other materials,the property and quality of steel has a direct relationship with the manufacturing process of industrial boiler,even,it affects the quality and safety of the project.Therefore,it is an important work to select the different kinds of steel,boiler steel has the following four requirements from the considerations of design:

Sufficient strength and rigidity

Boiler structure has no contact with the high temperature flue gas,generally,room temperature is the main basis for calculating the strength,the requirement of rigidity should be satisfied at the same time.

Paying attention to the purpose and performance

Generally,the plate beams and columns adopt alloy steel,the rest of the components basically use ordinary low-carbon steel.

Good welding performance

The framework generally adopts welding processing way,because the size of the framework is restricted by working conditions,the weld preheating and post weld heat treatment are very difficult,so,we should select the steel of good welding performance.

Appropriate brittle transition temperature

Sometimes,the working temperature of framework is very low,so,the brittle transition temperature of the steel should not be too high,it should be lower than the local lowest temperature.

The reasonable choice of steel,not only guarantees the bearing capacity of industrial boiler,but also ensures the normal operation of production,for Zhengzhou Boiler Co., Ltd.,it is also one of the important reasons why the industrial boilers here are reliable and cost-efficient.Many industrial boilers have been sold at home and aboard since 1945,for more details,please feel free to contact us!
