SAW welding is a type of arc welding while ERW welding is spot or seam welding. SAW stand for submerged arc welding while ERW stands for electric resistance welding.
ERW (Electric Resistance Welding) pipe is manufactured by rolling metal and then welding it longitudinally across its length. Seamless pipe is manufactured by extruding the metal to the desired length; hence ERW pipe has a welded joint in its cross-section, while seamless pipe does not have any joint in its cross-section through-out its length.
EFW: Electric Fusion Welding is a more general term which includes Electric resistance welding (ERW) and other types of welding such as Arc welding.
Sch 40 electric resistance welded pipe is generally used for utility lines such as compressed air and water lines.
A CEW pipe stands for a cold drawn electrically wielded pipe. Pipes can be made in a number of ways. One such method is to make pipes from sheet steel. The sheet is cut to the required width and rolled along the length. The ends are to be joined so that is forms a pipe. When they are welded using resistance then they are called ERW pipes and when they are electrically welded they are cold drawn electrically welded pipes or CEW pipes.
One pipe is electric resistance welded (erw) the other is extruded through a thimble. In other words one has a seam the other doesn't.
low pressure lines
MS pipe refers to mild steel pipe and ERW pipe is electric resistance welding pipe. The difference is ERW is made of very fine hard steel, while MS (black pipe) is made of malleable steel.
ERW pipes are round pipes welded from steel plates with longitudinal welds. It is used to transport oil, natural gas and other vapor-liquid objects, and can meet various requirements of high and low pressure.
