The selection of boiler tube diameter needs to consider the purpose, material, pressure level and working environment. The appropriate diameter can improve the operating efficiency and safety of the boiler.

As an important part of boiler equipment, boiler tube is usually made of seamless pipe and undertake multiple tasks such as transferring heat and bearing pressure. The diameter selection of boiler tubes directly affects the performance and safety of the boiler. So, how to choose the diameter of boiler tubes?

 

Boiler tube diameter

The diameter size of boiler tubes varies, and the common ones are DN15, DN20, DN25, DN32, DN40, DN50 and other specifications. These diameter sizes are selected according to factors such as the purpose, power and working environment of the boiler. Generally speaking, large boilers need to use larger diameter boiler tubes to ensure sufficient heat transfer efficiency and pressure bearing capacity; while small boilers can choose smaller diameter boiler tubes to reduce costs and save space. This is just like in oil production, in order to ensure that crude oil can be transported over long distances and efficiently, large diameter oil casing pipe will be selected.

 

Uses of boiler tubes of different diameters

Boiler tubes of different diameters play different roles in boilers. Large-diameter boiler tubes are usually used in key parts such as main steam pipes and main feed water pipes. They need to withstand higher pressures and temperatures, and have relatively high material requirements. Small-diameter boiler tubes are often used in auxiliary parts such as branch pipes and drain pipes. They have relatively low material requirements, but they also need to have certain pressure bearing capacity and corrosion resistance.

 

Recommendations for selecting boiler tube diameters

When selecting the diameter of a boiler tube, the following factors should be considered comprehensively:

1. The purpose and power of the boiler

Choose the appropriate diameter size according to the actual needs of the boiler to ensure that the heat transfer efficiency and pressure bearing capacity meet the requirements.

2. Material and process

The material and process of the boiler tube also have a certain impact on the diameter selection. High-quality materials and processes can improve the pressure bearing capacity and service life of the boiler tube, thereby reducing maintenance costs.

3. Safety considerations

When selecting the diameter of a boiler tube, its safety should be fully considered. Too small a diameter may cause pipe blockage or insufficient pressure bearing capacity, while too large a diameter may increase costs and reduce heat transfer efficiency.

 

Summary

In summary, the selection of boiler tube diameter needs to consider multiple factors, including the purpose, power, material, process and safety of the boiler. Only by choosing the appropriate diameter can the normal operation and safety of the boiler be ensured. Therefore, when purchasing boiler tubes, it is recommended to consult a professional boiler engineer or manufacturer to ensure that the appropriate product is purchased.
