Deluge system couplings
Deluge system couplings
(OP)
Is there a difference in 300# rolled grooves and what I know as Victaulic couplings? Has anyone done comparison test on performance in overpressure situations. No doubt, screw couplings are problematic; you have to go one schedule higher to ensure adequate wall thickness after the threads are cut and the threads are notorious as start points for significant corrosion over time.
If grooved is stronger than threaded, perhaps I should consider changing to grooved where we currently allow threaded, I won’t budge off butt welded flange for larger than 2” unless some really good data is available.
Any information is appreciated.

The piping for Fire Suppression has higher testing standards as well. ASTM 795.
I can understand then flange requirement somewhat. But I think you will again find great comparison when using roll grooved.
I used to have a copy of the groove testing standard. I believe UL 213..?
Victaulic if the Father, so we generally just say "Vic" coupling when speaking about them even thought they may be made by someone else.
Most of the grooved stuff we use is rated to #300, but they may be some stragglers out there. The UL and or FM mark will tell the tale.
