| Feature | Socket Weld Fittings | Threaded Fittings |
|---|---|---|
| Connection Method | Pipe end inserted into socket, joined by fillet welding | Pipes screwed together via internal/external threads |
| Strength & Reliability | Strong, permanent, leak-proof joint; resists vibration and stress | Less secure, can loosen with vibration or thermal expansion |
| Pressure & Temperature | Suitable for high-pressure, high-temperature applications | Best for low to medium pressure and moderate temperatures |
| Installation | Requires welding; skilled labor and equipment needed | Easy installation with basic tools; no welding required |
| Maintenance | Permanent connection; difficult to disassemble | Easily disassembled for maintenance or modification |
| Leakage Risk | Low risk due to welded joint | Higher risk; threads may leak over time or with vibration |
| Cost | Higher installation cost (labor, equipment) | Lower installation cost |
| Typical Applications | Oil & gas, chemical, power plants, critical piping systems | Plumbing, HVAC, small industrial systems, frequent maintenance |
| Internal Flow | Smooth surface, less turbulence and pressure drop | Threads cause flow restrictions and potential particulate traps |
| Durability | More durable, suitable for thicker pipe walls | Less durable, not ideal for thick-walled pipes |
