Tongue and groove flanges are widely used in industries requiring secure, high-pressure, and leak-proof connections. These flanges are designed with matching raised surfaces—one with a protruding tongue and the other with a matching groove—ensuring a tight, self-aligning seal. At Piyush Steel, we manufacture and supply SS 304 tongue and groove flanges, SS 316 flanges, Inconel 625 flanges, Duplex 2205 flanges, and Titanium flanges, meeting global industry standards.
Applications of Tongue and Groove Flanges
1. Oil & Gas Industry
In high-pressure pipelines, tongue and groove flange applications include secure sealing for oil refineries, offshore drilling platforms, and petrochemical plants. Inconel 625 flanges are preferred due to their exceptional corrosion resistance.
2. Chemical Processing Plants
These flanges are ideal for handling corrosive chemicals and high-temperature processes. SS 316 tongue and groove flanges offer superior resistance to harsh chemical environments, ensuring durability and safety.
3. Power Generation
Used in steam, nuclear, and thermal power plants, Duplex 2205 tongue and groove flanges provide excellent mechanical strength and resistance to thermal stress, making them ideal for boiler and turbine applications.
4. Marine & Shipbuilding Industry
Marine pipelines require leak-proof and corrosion-resistant flange connections. Titanium tongue and groove flanges are commonly used in seawater applications due to their high strength and oxidation resistance.
5. Aerospace & Defense
In high-performance aerospace applications, SS 304 and Inconel 718 tongue and groove flanges are used in fuel systems, hydraulic lines, and structural components, ensuring reliable, high-strength connections.
Tongue and Groove Flange Design
The tongue and groove flange design consists of a raised tongue on one flange and a matching groove on the other. This design ensures precise alignment, reducing stress concentration and preventing leaks. It allows the use of gaskets, metallic seals, and soft materials, enhancing joint reliability under high-pressure and high-temperature conditions.
