The design and working pressure of high-pressure boiler tubes in Jiangsu depend on specific applications and requirements, so different types of high-pressure boiler tubes may have different pressure levels. Generally speaking, the pressure of high-pressure boiler tubes can be divided into the following common levels:

Low pressure boiler tube: Low pressure boilers are usually designed to operate at lower pressures, typically within the range of 0.1 to 2.5 megapascals (MPa). These boilers are mainly used for heating, hot water, and some industrial processes.

Medium pressure boiler tube: Medium pressure boilers operate at medium pressure, typically within the range of 2.5 to 6.0 MPa. They are used in some industrial applications to generate steam, such as in the chemical industry.

High pressure boiler tubes: High pressure boiler tubes are designed to operate at relatively high pressures, typically in the range of 6.0 to 13.0 MPa or higher. These boilers are typically used in large power plants and industrial processes to generate high-temperature and high-pressure steam.

Ultra high pressure boiler tubes: Ultra high pressure boilers operate at very high pressures, usually above 13.0 MPa. These boilers are typically used for special industrial applications, such as nuclear power plants.

The manufacturer of high-pressure boiler tubes suggests that it should be noted that the working pressure of high-pressure boiler tubes must be designed and manufactured in accordance with relevant standards and regulations to ensure safety and reliability. The selection and use of high-pressure boiler tubes should comply with relevant international and national standards and specifications to ensure compliance with laws, regulations, and safety requirements. Therefore, when selecting and using high-pressure boiler tubes, relevant professionals should be consulted and applicable regulations and standards should be followed.
