The Applications Of Different Pressure Ratings Of Carbon Steel Flanges

The Applications of Different Pressure Ratings of Carbon Steel Flanges

 

Carbon steel flanges are classified according to pressure ratings, and they serve different functions in industrial piping systems depending on their rating. Pressure ratings are based on the maximum pressure that a flange can withstand without failure.

 

1. Class 150 Carbon Steel Flanges

These flanges have a pressure rating of 150 pounds or 2.0 megapascals (MPa). They are suitable for low-pressure systems such as potable water supplies and low-pressure air lines. These flanges are common in construction, power generation, and oil and gas industries.

 

2. Class 300 Carbon Steel Flanges

These flanges have a pressure rating of 300 pounds or 5.0 MPa. They are suitable for medium-pressure systems such as medium-pressure water lines and chemical processing pipelines. They are common in industries such as water treatment, petrochemicals, and coal gas and oil.

 

3. Class 600 Carbon Steel Flanges

These flanges have a pressure rating of 600 pounds or 10.0 MPa. They are suitable for high-pressure systems such as oil and gas transportation and refining. They are widely used in high-temperature, high-pressure, and high-viscosity applications.

 

4. Class 900Carbon Steel Flanges

These flanges have a pressure rating of 900 pounds or 15.0 MPa. They are primarily used in high-pressure petrochemicals, natural gas, and metallurgy industries. They are commonly used for high-pressure gases and liquids, which are processed and extracted.

 

5. Class 1500 Carbon Steel Flanges

These flanges have a pressure rating of 1500 pounds or 25.0 MPa. They are suitable for higher pressure systems, such as high-pressure steam environments for SAGD and heavy oil extraction. They are also commonly used in natural gas transmission pipelines and gas-sealing equipment.

 

In conclusion, the choice of carbon steel flange is typically based on the required pressure rating for the system and the application scenario. The correct selection and use of carbon steel flanges can ensure system reliability and long-term performance.
