What is a Raised Face Flange?
A raised face flange features a raised surface around the bore, providing a larger contact area for the gasket. This design enhances sealing capability, making it suitable for high-pressure and high-temperature applications. The raised face design is widely used in industries requiring leak-proof connections in piping systems.
Key Benefits of Raised Face Flanges
- Enhanced Sealing – The raised face design allows for greater gasket compression, ensuring a tighter, more secure seal.
- Leak Prevention – Suitable for high-pressure applications where maintaining a secure connection is critical.
- Versatility – Compatible with various gasket types, including ring and full-face gaskets, allowing for flexibility in different environments.
- Corrosion Resistance – When manufactured from specialty metals, raised face flanges offer superior resistance to corrosive elements found in industrial operations.

Raised Face Flanges vs. Flat Face Flanges
Raised face flanges and flat face flanges serve similar functions but are used in different applications:
- Raised Face Flanges – Designed for high-pressure systems where superior sealing is required. The raised surface ensures better gasket compression.
- Flat Face Flanges – Commonly used in lower-pressure systems where load distribution across the entire flange face is necessary. They are often required in cast iron and fiberglass piping systems to avoid uneven stress.
