A flange is a protruding, flat, or raised rim used in engineering and plumbing applications. It serves as a connecting point for pipes, valves, or equipment, allowing for secure and leak-resistant connections. Flanges come in various shapes and sizes to accommodate different industrial needs.
- FF stands for Flat Face.
- RF stands for Raised Face.
- RTJ stands for Ring Type Joint.
These terms describe the surface finish and sealing characteristics of flanges. FF has a flat, smooth face, RF has a raised face with a gasket sealing surface, and RTJ has a groove to accommodate a ring gasket for high-pressure applications.
