Groove & Tongue Flanges are widely used in critical and non-critical applications where tight sealing and structural integrity are necessary. These flanges are manufactured as per ANSI B16.5, ANSI B16.47, and MSS SP-44 standards, making them highly suitable for both high-pressure and atmospheric conditions. sunriseindustries provides these flanges in various face types, including large and small tongue & groove profiles, ensuring perfect compatibility with custom fittings and pipes.
We offer Groove & Tongue Flanges in an extensive range of materials such as Stainless Steel, Carbon Steel, Alloy Steel, Duplex and Super Duplex Steel, Inconel, Monel, Hastelloy, Titanium, and Copper Nickel. These materials are chosen for their mechanical strength, corrosion resistance, and pressure-bearing capabilities, allowing our flanges to perform reliably in demanding environments like offshore platforms and refineries.
All Groove & Tongue Flanges by sunriseindustries are available in various pressure ratings ranging from Class 150 to 2500 and DIN ND standards. With sizes from ½” NB to 60” NB, we accommodate a wide spectrum of industrial requirements. These flanges are also available with Raised Face (RF), Ring Type Joint (RTJ), and customized face types as per project needs. Our in-house engineering team ensures all products are dimensionally accurate and fully inspected before dispatch.
sunriseindustries specializes in supplying Groove & Tongue Flanges for industries requiring secure and strong pipeline connections under fluctuating temperatures and high pressure. Unlike traditional flanges, these flanges provide better sealing without the need for additional gaskets. Their design supports easy assembly and disassembly, making them highly cost-effective over long-term operations in maintenance-heavy facilities.
