Standard Pipe Showdown: Continuous Weld vs. Electric Resistance Weld

Nick LaMonto, piping superintendent at Chicago-based Atomatic Mechanical Services, threads pipe every day. As an experienced piping professional, he knows the importance of tool longevity and what it can cost when working with an inferior product.

We put Nick’s machines to the test, threading both types of steel standard pipe: continuous weld and electric resistance weld.

 

First up, Nick threads continuous weld standard pipe.

“It cuts awful nice,” Nick said, “without any hard spots.”

It’s a relief to Nick, who knows hard sports in the pipe will break the cutting wheel and he can’t afford to beat up his threaders and dyes.

“I need those expensive pipe machines to last,” Nick said.

Nick has no problem getting the fitting on. After three full turns, he’s done and confident that his seal will last.

 

Next up, Nick works with the import ERW pipe.

He first notices things aren’t going as planned when the first three threads tear.

“I probably won’t be able to get a fitting on here either,” Nick said. “That’s not going to seal. The threads have been torn off and it’s not even tapered– a pipe thread needs to be tapered before it seals.”

He knows this pipe will leak, leaving it unusable. 

 

See it for yoursellf. Watch the Standard Pipe Showdown video to learn why CW pipe is superior to import ERW, direct from a Chicago piping professional who uses it on every job.

Additional facts about CW Pipe:

  • 100% American made steel
  • Heated to a temperature of 2,450 °F
  • The heated edges are fused to form a smooth seam that’s free of flash from the weld
  • Finished with an annealing process that creates pipe with a uniform grain structure

The result: stronger and more ductile pipe that bends, cuts and threads easier.
