Pressure rating and applications of boiler steel pipe

The pressure rating of boiler steel pipes indicates the highest operating pressure that the pipes can endure. Boiler steel pipes are typically classified into three pressure categories based on international standards: low-pressure, medium-pressure, and high-pressure.

Low-pressure boiler steel pipes:

These pipes are designed for boilers operating at pressures not exceeding 2.5MPa. Common pressure ratings for low-pressure boiler steel pipes include: 0.8MPa, 1.0MPa, 1.25MPa, and 1.6MPa.

Medium-pressure boiler steel pipes:

Suitable for boilers with operating pressures ranging from 2.5MPa to 9.8MPa. Typical pressure ratings for medium-pressure boiler steel pipes are: 2.5MPa, 4.0MPa, 6.4MPa, and 9.8MPa.

High-pressure boiler steel pipes:

Intended for boilers with operating pressures above 9.8MPa. Common pressure ratings for high-pressure boiler steel pipes are: 13.7MPa, 15.9MPa, 20.0MPa, 24.0MPa, and 32.0MPa.

Application of Boiler Steel Pipes with Different Pressure Ratings

- Low-pressure boiler steel pipes:

Ideal for specific applications such as hot water supply systems in hospitals, schools, hotels, etc., where lower pressure levels are sufficient for the needs of these settings.

- Medium-pressure boiler steel pipes:

Well-suited for boiler systems in general industrial and civil buildings, including hot water boilers and steam boilers. These pipes offer a balanced pressure level and cost-effectiveness, meeting the requirements for standard production and living needs.

- High-pressure boiler steel pipes:

Extensively used in industries like chemical, electric power, and petroleum, where high-temperature and high-pressure steam is necessary for production processes. High-pressure boiler steel pipes can withstand such conditions, ensuring the smooth operation of these processes.

In summary, the selection of the appropriate pressure rating for boiler steel pipes should be based on the actual operating pressure to guarantee the safe and stable functioning of the system. It is crucial to install, use, and maintain boiler steel pipes in strict accordance with their pressure rating specifications to ensure their safety and reliability.
