Types of Copper Blind Flanges
These flanges have a raised face around the bore hole, which helps in creating a tighter seal when compressed against a gasket. The raised face provides a flat surface for the gasket to rest on, resulting in improved sealing capabilities. Unlike RF flanges, flat face flanges have a flat surface without any raised face.
- Raised Face (RF) Blind Copper Flanges: These flanges have a raised face around the bore hole, allowing for better sealing when compressed against a gasket.
- Flat Face (FF) Blind Copper Flanges: These flanges have a flat surface without any raised face.
- Ring Type Joint (RTJ) Blind Copper Flanges: RTJ flanges have a groove on the face to accommodate a metal ring gasket.
- Tongue and Groove (TG) Blind Copper Flanges: These flanges feature a tongue-like protrusion on one flange and a corresponding groove on the other.
- Lap Joint (LJ) Blind Copper Flanges: LJ flanges consist of two parts—a stub end and a backing flange.
Features of Copper Blind Flanges
- Copper has excellent corrosion resistance, making blind copper flanges suitable for applications where resistance to oxidation, moisture, and certain chemicals is required.
- Copper is known for its high thermal conductivity, allowing blind copper flanges to efficiently transfer heat in applications where heat dissipation is important.
- Copper is an excellent conductor of electricity, making blind copper flanges suitable for applications where electrical grounding or conductivity is needed.
- Copper is a highly ductile metal, which means it can be easily shaped or formed into complex flange configurations, allowing for customized designs and adaptations.
- Copper has an attractive appearance, with its characteristic reddish-brown color. Blind copper flanges can provide an aesthetic appeal in applications where the visual appearance is important.

Uses of Copper Blind Flanges
Copper's corrosion resistance and excellent thermal conductivity make blind copper flanges suitable for plumbing systems. They can be used to seal off the ends of pipes or fittings, providing a secure closure when a connection is not needed. Copper's high thermal conductivity makes blind copper flanges well-suited for heat exchangers. They can be used to close off the ends of heat exchanger tubes, ensuring proper sealing and efficient heat transfer.
Quality of Copper Blind Flange
The quality of copper used in manufacturing blind flanges is crucial. High-grade copper with the appropriate chemical composition and purity ensures better corrosion resistance and mechanical properties. Reputable manufacturers source copper from trusted suppliers and conduct quality checks to ensure the material meets required standards. The manufacturing process plays a vital role in the quality of blind copper flanges.
