Difference between ASTM A928 UNS S31803 ERW and EFW pipe
| Property | ERW | EFW |
|---|---|---|
| Welding Method | Electric Resistance Welding | Electric Fusion Welding |
| Weld Quality | Low weld quality compared to EFW | High weld quality with fewer defects |
| Diameter Range | Available in wide range of diameters but Small diameters | Larger diameters and thick-walled pipes. |
| Manufacturing Process | By applying pressure and an electric current to the pipe edges, welds are formed. | The process of welding involves melting the pipe's edges and connecting them with an electric arc. |
| Applications | utilised in less demanding situations when the quality of the weld is not as important. | High pressure and temperature applications due to stronger welds. |
| Strength | Low yield and tensile strength compared to EFW | High yield and tensile strength due to the complete fusion of the weld. |
| Cost | Less | More |
| Surface Finish | Imperfections and irregularities surface finish | Smoother surface finish |
| Inspection | More extensive inspection and testing than EFW | Less extensive inspection than ERW |
