Applications of seamless boiler tubes with different pressure ratings

The pressure rating of seamless boiler tubes indicates the maximum operational pressure that these pipes can endure. In accordance with international standards, the pressure ratings for seamless boiler tubes are typically divided into three categories: low-pressure, medium-pressure, and high-pressure.

Low-pressure seamless boiler tubes:

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

Medium-pressure seamless boiler tubes:

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

High-pressure seamless boiler tubes:

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

Applications of Seamless Boiler Tubes with Different Pressure Ratings

- Low-pressure seamless boiler tube:

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

- Medium-pressure seamless boiler tube:

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

- High-pressure seamless boiler tube:

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

In summary, the selection of the appropriate pressure rating for seamless boiler tubes 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 seamless boiler tubes in strict accordance with their pressure rating specifications to ensure their safety and reliability.
