Socket Weld Flange

Socket Weld Flange (SW Flange)

Socket Weld Flange is a high-strength pipe flange designed for small and medium diameter piping systems where reliable sealing and pressure resistance are required. The pipe is inserted into the socket section of the flange and secured by fillet welding, creating a compact and durable connection.

With its accurate positioning structure and excellent sealing performance, Socket Weld Flange is widely used in high-pressure industrial piping systems, especially for applications requiring stable connections and limited installation space.

Product Features

• Socket Welding Design
The pipe is inserted into the flange socket before welding, providing accurate alignment and reducing installation difficulty.

• High Pressure Performance
Suitable for pressure applications from Class 150 to Class 2500, offering reliable performance in demanding piping environments.

• Compact Structure
Compared with Weld Neck Flanges, Socket Weld Flanges have a shorter overall design, making them suitable for pipelines with limited space.

• Excellent Sealing Reliability
The combination of socket connection and welding reduces leakage risks and ensures stable operation.
