Features of Class 300 Socket Weld Flange
- Pressure Rating: Class 300, suitable for medium-pressure systems, with specific pressure values varying with temperature.
- Size Range: Typically ranges from 1/2 inch to 3 inches, with specific sizes selected based on pipeline requirements.
- Materials: Common materials include carbon steel, stainless steel, alloy steel, etc., chosen based on the application environment.
- Sealing Performance: The socket weld design provides excellent sealing, making it suitable for high-pressure or high-vibration environments.
- High Strength: The welded connection ensures a robust joint between the flange and the pipe.
The ANSI/ASME B16.5 Class 300 Socket Weld Flange is a standardized socket weld flange suitable for medium-pressure and small-diameter piping systems. It offers excellent sealing and high strength, making it widely used in industries such as oil and gas, chemical, and power.

FAQ
- Excellent sealing: Ideal for high-pressure or high-vibration environments.
- High strength: Welded connection ensures a robust joint.
- Suitable for small-diameter pipes: Typically used for pipes 2 inches and below.
- Socket Weld Flanges provide better sealing and strength, making them suitable for high-pressure or high-vibration applications.
- Slip On Flanges are easier to install and more cost-effective but are generally used for lower-pressure applications.
- Consider the following factors:
- Pipe size and schedule
- Pressure and temperature requirements
- Material compatibility with the fluid or gas
- Industry standards and regulations.
