- Concave Face (FM)
- Convex Face (MF)
- Tongue and Groove (TG)
- Ring Joint (RJ)
Designed for direct pipe welding with superior structural integrity. Capable of withstanding high temperatures, pressure fluctuations, and repeated stress cycles. Nominal pressure range: 0.25-2.5Mpa with concave-convex sealing surfaces.
Ideal for carbon steel pipe connections up to 2.5Mpa. Available in smooth, concave-convex, and tongue-groove sealing types. Cost-effective solution for mild service conditions including low-pressure air and water systems.
Perfect for corrosive environments where the flange contact surface requires corrosion-resistant materials while maintaining structural integrity with carbon steel backing.
