Optimizing Your Piping System with Socket Weld Flanges
Fortune Fittings Pvt. Ltd. is a leading manufacturer and supplier of high-quality Socket Weld Flanges, essential for ensuring reliable connections in piping systems. Our extensive range includes ASME B16.5 and ASME B16.47 Socket Weld Flanges, catering to diverse industrial applications with precision and durability.
Understanding Socket Weld Flanges
Socket Weld Flanges are designed to provide a robust and leak-proof connection by welding a pipe into a socket within the flange. This type of flange is commonly used in high-pressure and high-temperature environments due to its superior strength and ease of installation. The pipe is inserted into the flange’s socket, and a fillet weld is applied around the joint’s perimeter, ensuring a secure fit.
Features and Benefits
- High Strength: Crafted from premium stainless steel materials, our Socket Weld Flanges offer exceptional strength and durability, making them ideal for demanding applications.
- Corrosion Resistance: Stainless steel construction provides excellent corrosion resistance, ensuring longevity and reliability in corrosive environments.
- Ease of Installation: The socket weld connection simplifies installation, allowing pipes to be inserted into the flange socket and securely welded for a leak-proof joint.
- Versatile Applications: Socket Weld Flanges find applications in diverse industries, including oil and gas, chemical processing, power generation, and automotive engineering (SAE applications).
