Quelfire Fire Collars

Quelfire QWR CE Marked Fire Collars prevent the spread of fire through PVC, HDPE, PP & ABS pipes where they penetrate fire compartment walls and floors. The QWR CE Marked Fire Collars consist of a continuous pressed stainless steel flexible shell containing high performance graphite based intumescent material which reacts under the influence of heat to exert pressure on the pipe as it softens to form a carbonaceous char which provides an effective insulation plug thus preventing smoke and fire passing through to the adjoining compartment. The QWR CE Marked Fire Collar has built in fixing lugs which are used to secure it to the structure.
