FAQ
- The maximum working pressure of a Class 600 flange at ambient temperature is 600 psi. The specific pressure-temperature ratings can be found in the ASME B16.5 standard.
- Selection criteria:
- Raised Face (RF): Suitable for general conditions.
- Flat Face (FF): Used for low-pressure and non-critical applications.
- Ring-Type Joint (RTJ): Used for high-pressure and high-temperature applications.
- Common materials include carbon steel (e.g., ASTM A105), stainless steel (e.g., ASTM A182), and alloy steel (e.g., ASTM A182 F11).
- Installation considerations:
- Ensure proper alignment of the pipe and flange to avoid stress concentration.
- Use appropriate gaskets and bolts, and tighten to the specified torque.
- Perform leak tests to ensure sealing integrity.
- The main differences are in pressure rating and wall thickness:
- Class 600 flanges are suitable for high-pressure environments and have thicker walls.
- Class 150 flanges are suitable for low-pressure environments and have thinner walls.
- Yes, but it is necessary to ensure that custom flanges meet the strength and sealing requirements of the ASME B16.5 standard and provide relevant test reports.
