Socketed welding flange
- Detail
-
Socket Weld Flange (SW Flange) is a high-performance pipe fitting designed for permanent, leak-tight connections in industrial piping systems. Characterized by its socketed end—where the pipe is inserted into the flange bore before welding—it delivers exceptional structural integrity and sealing reliability, making it ideal for medium-to-high pressure and temperature applications.
Core Features & Benefits
- Superior Connection Stability
The socket design ensures full circumferential contact between the pipe and flange, distributing stress evenly across the joint. Two fillet welds (inner and outer) reinforce the connection, preventing leakage even under cyclic pressure or vibration.
- Compact & Space-Saving
Compared to weld neck flanges, socket weld flanges have a shorter face-to-bore length, making them perfect for tight installations where space is limited (e.g., crowded equipment skids or confined pipelines).
- Efficient Installation
No need for precise pipe end beveling—simply insert the pipe into the socket (leaving a small gap for weld penetration) and weld. Reduces installation time and labor costs while ensuring consistent joint quality.
- Excellent Corrosion Resistance
Manufactured from high-grade stainless steel and carbon steel, the flange resists corrosion, oxidation, and chemical erosion, extending service life in harsh environments.
- High Pressure/Temperature Rating
Engineered to withstand working pressures up to ANSI Class 2500 and temperatures ranging from -29°C (-20°F) to 538°C (1000°F), adapting to diverse industrial conditions.
