Face Type: Tongue Design
Tongue and Groove flanges feature a raised ring with machined depression for creating watertight connections in industrial fluid and gas transport systems.
Material Performance
- Carbon Steel Tongue and Groove Flanges offer moderate strength with higher carbon content
- Reliable performance across high temperature and pressure conditions
Flange Type: Weld Neck (WN)
Weld neck flanges effectively transfer stress to connected pipes, reducing high-stress concentration at the flange base. Manufactured through forging process and welded directly to piping systems.
