Applications of ANSI / ASME B16.5 Class 400 Blind Flange
- Sealing the end of the pipeline: Used to seal the end of a pipeline where no connection is required or where the flow needs to be stopped, facilitating inspection and maintenance.
- High-pressure systems: Class 400 blind flanges are used to withstand medium to high-pressure systems and are widely used in industries such as oil, gas, chemicals, power, and water treatment.
- Temporary pipe closure: Used to temporarily close pipelines during testing, maintenance, or expansion, ensuring that no fluid leaks.
ANSI / ASME B16.5 Class 400 Blind Flange is a flange used to seal the end of a pipeline. It is commonly used in systems where no equipment needs to be connected or where periodic access is required for inspection and maintenance. It has no through-hole, effectively sealing the pipe and preventing leakage of liquids or gases. Class 400 indicates that the flange can withstand a maximum working pressure of about 400 pounds per square inch (psi), depending on the temperature and material.

Tanya Jawab Umum
- Choose the appropriate material based on the application environment and the corrosiveness of the medium, such as carbon steel, stainless steel, or alloy steel, ensuring the flange has sufficient corrosion resistance and strength.
- Class 400 blind flanges can withstand a maximum working pressure of about 400 psi at room temperature, but the actual pressure will vary with temperature and material. You should confirm the pressure based on the specific operating conditions.
- Yes, especially in high-pressure or high-temperature environments, regular inspection of the flange and gasket for wear or corrosion is necessary to ensure long-term reliable sealing performance.
