Seismic protection for Fire Sprinkler Systems

New from Metraflex, the leader in seismic pipe protection, Metraflex® Fireloop® expansion joint provides seismic protection and is UL listed for sprinkler systems.

The new Fireloop® expansion joint is capable of movement in all directions, and should be installed anywhere building or pipe movement is expected, including seismic, thermal growth and building settlement.

UL listed for fire sprinkler systems, the Fireloop has the unique ability to handle movement in all directions, bringing the same seismic protection offered in the regular Metraloop expansion joint to this critical, life-saving application. Extremely compact, it simplifies sprinkler system design and eliminates the need for multiple, convoluted joints or grooved couplings fabricated on site.

In seismic applications, the Fireloop is positioned anywhere movement is expected, such as the building's seismic joint. When the loop is installed vertically or horizontally, the 180-degree return bend of the loop must be supported to allow the entire Fireloop to move freely.

Already installed in thousands of seismic applications for fire sprinkler systems, the Fireloop expansion joint is significantly more compact than grooved pipe loop arrangements.
