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.

Which types of pipe are commonly used staircase handrail seamless or nonseamless?
Seamless pipe is very expensive, and is only used in certain applications, such as steam condensate return, where ERW (seamed) pipe would not last as long. For a handrail, go with the ERW.
What is the difference between seamless and welded pipe fittings?
Seamless (SMLS) pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. Seamless pipe withstands pressure better than other types, and is often more easily available than welded pipe.Welded pipe is formed by rolling plate and welding the seam. The weld flash can be removed from the outside or inside surfaces using a scarfing blade. The weld zone can also be heat treated to make the seam less visible.

Difference between ERW and SAW welding?
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.
What is difference between ERW and CRW Pipes?
ERW: Electric Resistance Welding tube - tubes are rolled and joined With welding - fin cut is there CRW: Cold Drawn tube - without fin cut - Draw process
Difference between ERW and Seamless pipes grades?
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.
Difference between ms pipe and erw pipe?
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.

What will happen if seamless pipe is used in place of erw pipes?
It increases only cost..
