Stainless Steel EFW Welded Pipe Types
Why use x-rays welding for EFW Pipes?
Stainless steel and other metallic pipes are in use in many industries and applications. The metal pipes are made through various processes. There are hot rolling, cold drawing, electric resistance welding and electric fusion welding procedures. The electric fusion welding is done by heating up the metal in the electrode through electric fusion until it melts and then making up the pipe.
Since the material is fully melted, pressurization is not required after the process. X ray welding is relatively new in the electric fusion welding technology. X-rays require special conditions to be used. So the room requirements are higher and costly with X-ray welding. But as a compliment, the X-rays focus on smaller spot with accuracy and can melt the metal faster. This allows the impacted zone to be as minimal as possible.
So the mechanical properties of the material remain intact for the most part. Usually with electric fusion welding there could be a small deformation of the pipes. With X-rays, the deformation is little to none. So the pipe does not need additional treatments in terms of wall thickness, absolute roughness or the shape. For these reasons, manufacturers are turning to X-ray welding for EFW Pipes.
