What is a Socket Weld Flange?
A Socket Weld Flange is a type of pipe flange used for small-diameter, high-pressure pipelines. It has a recessed socket where the pipe is inserted and then fillet welded around the outer edge. Socket weld flanges are ideal for high-integrity, leak-proof piping systems in critical applications.
🧱 Types of Socket Weld Flanges
| Type | Description | Use Case |
| Plain Socket Weld | Standard design for small bore piping | Oilfield and gas distribution |
| Raised Face (RF) | Provides extra sealing surface for gaskets | Chemical and petrochemical plants |
| Flat Face (FF) | Even contact with gasket, often for cast equipment | Civil water pipelines, HVAC systems |
| Socket Weld Orifice | Integrated with orifice plates for flow measurement | Process piping |
🌐 Standards – ANSI & DIN Socket Weld Flanges
| Standard | Pressure Ratings | Region / Use |
| ANSI / ASME B16.5 | Class 150, 300, 600, 900, 1500, 2500 | Oilfield, marine, chemical plants |
| DIN EN 1092-1 | PN 6, PN 10, PN 16, PN 25, PN 40 | Civil works, utilities, low-pressure use |
📊 Pressure Ratings of Socket Weld Flanges
| Standard | Class / Rating | Max Pressure (approx.) |
| ANSI Class 150 | 285 psi (19.6 bar) | Water pipelines, drainage |
| ANSI Class 600 | 1480 psi (102 bar) | Oil & gas, petrochemical |
| ANSI Class 1500 | 3705 psi (255 bar) | Steam systems, offshore rigs |
| DIN PN16 | 232 psi (16 bar) | Civil HVAC, waste treatment |
| DIN PN25 | 362 psi (25 bar) | Pressurized water supply |
🛠 Materials for Socket Weld Flanges
