As the title says, I'm starting to install 6" spiral duct (26ga) - (right now its collecting dust on the outside (on the ground) vs installed)
I wanted to know people's experience with installing Spiral pipe. Should I avoid crimping the pipe ends where needed?
I believe I've read that crimping can add a small amount of resistance, not sure if it'd be significant enough to worry but should I always use couplings instead of crimping ?
I can get (and have bought a few) of the proper couplings from my HVAC supplier. I've attached a picture. These aren't overly expensive, but these along with all other fittings, the $$$ is adding up.
In the pic, if the air is following the arrow, I was thinking also to cut off, or flatten the crimping on the Left side, to reduce as much resistance. I believe without the crimping, I can still get the pipe over the coupling.
I guess what I'm asking is, if I use these couplings, am I adding just as much resistance as crimping the pipe itself.?
Is it worth worrying over? Thanks for any and all feedback.
