Smart seismic expansion loop
The Seismic BreakAway coupling is designed for seismic events when hanger rods are too short to allow the full-rated movement of seismic expansion loops.
Metraflex’s Seismic BreakAway coupling is designed for seismic events when hanger rods are too short to allow the full-rated movement of seismic expansion loops. The coupling is designed to separate at a preset load greater than the seismic joint’s static weight. This allows the loop to move freely, preventing further damage. After activation, the reusable coupling can be reset and used again with the seismic joint. In nested loop installations, multiple BreakAway couplings can be used to support long return bends. The couplings can also be used with saddles to prevent long flexible legs on large seismic loops from sagging.
