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.
Difference between seamless and erw pipe?
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.
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
What is EFW pipe?
Electrical fusion welded pipes made by rolling plate or sheet into pipe and joined by electrical fusion welding.
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.
When was EADS EFW created?
EADS EFW was created in 1955.
What is EADS EFW's population?
EADS EFW's population is 1,143.

When was Teesside EfW plant created?
Teesside EfW plant was created in 1998.
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.

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.
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
What is a post sound check function to one direction?

Is DSAW a better weld than ERW?
Look back at the history of failures with ERW and it explains itself. The liklihood of a failure is higher and the consequences are enormous.
