Composition

The QWX 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 QWX Fire Collar has built in fixing lugs which are used to secure it to the structure.

Durability

QWX Fire Collars are expected to last the lifetime of the building.

Application / installation


QWX Fire Collars should be used where a large diameter plastic pipe penetrates a fire rated wall or floor.
For vertical pipework, one unit should be installed to the underside of the floor, and for the QWX350 and QWX400 one units should be fitted on both sides of the concrete floor. For horizontal pipework one unit should be fitted to each side of the wall.

The soffit of the floor or the face of the wall must be smooth and where there are irregularities in the surface, the space between the flange of the unit and floor or the wall should be made good using QSS QuelStop CE Marked Intumescent Acoustic Acrylic Sealant.

The QWX Fire Collar should be fed around the plastic pipe, securing the ends together by passing the tongues on one end through the slots on the other end. The tongues should then be bent back and the unit secured to the structure using the integral fixing lugs.

The QWX Fire Collar must be secured to concrete and masonry construction using steel sleeve anchors.
