ansi smacna- anyone familiar w
cody company sent us their co-lox "button lock" furnace pipe for strong pipe.
the cody co-lox system consists of button punches on the crimped ends that "snap" into place behind an inside hem on the uncrimped ends of all pipe, elbows and fittings in 4-14" dia. strong, permanent field joints can be made in a minimum of time using sheet metal snips, a hand crimping tool and a hand snaplock punching tool. for increased strength and durability, additional beads have been added to the pipe at intervals of 6" from crimp hem 12"-12"-12" center 6" from bottom of pipe.
my question: anyone ever uses this product before? does cody company's product meet the smacna standards? how can you verify?
thank you very much.
