Component of Swivel Flange
Forged Outer Ring
- Rotates around the pipe to allow precise alignment with mating flanges.
- Ensures easy installation without moving the pipe.
- Provides a bolt connection surface compatible with standard flange patterns.
Heavy Forged Welding Hub
- Forms the structural connection to the pipe through welding or threading.
- Provides strength and stability under high-pressure and high-temperature conditions.
- Supports rotational movement of the outer ring without compromising integrity.
Gasket
- Sits between the flange faces to create a leak-proof seal.
- Available in materials suitable for specific fluids, temperatures, and pressures.
- Can be flat, raised, or ring type, depending on flange design.
