Fire/Smoke Containment Pipe Applications

GF Harvel FlameTech has been developed for use as containment piping in visual leak detection systems in areas where flame spread and smoke generation are of concern (i.e., containment piping installed in return air plenum applications). Major building and mechanical codes require that combustible piping installed within an air plenum must have a maximum flame spread of 25 and a maximum smoke development rating of 50. Based on large-scale burn testing of finished piping products conducted by ULC, GF Harvel FlameTech piping meets this fire performance requirement and is Listed by ULC for surface burning characteristics.

In addition to excellent fire performance properties, GF Harvel FlameTech translucent piping offers good optical qualities. This enables its use as containment piping for high-purity piping runs where quick identification of primary tubing and visual leak detection are critical. Primary tubing can be readily identified and inspected visually through the pipe wall. Utilizing a flashlight or alternate light source greatly enhances this unique attribute.
