Champion Flame Shield® Phenolic Conduit


 

What kinds of joints are available, and how many will I need?

The Phenolic Joining System includes the Adhesive Joint, which is the straight socket joint combined with the appropriate adhesive. The adhesive is applied to the spigot end of the conduit. Various straight socket expansion joints are also available; expansion fittings should be provided to compensate for thermal expansion and contraction. You can find more information on the Phenolic Joining System in our Champion Flame Shield® catalog.

What are the main differences between epoxy and phenolic RTRC conduits?

The main difference is fire resistance. Epoxy RTRC conduit has an operating range of -60°F to 250°F whereas phenolic (Flame Shield®) RTRC can be exposed to temperatures up to 1,850°F for two (2) hours. Phenolic conduit also meets the elevated temperatures requirements for exposed conduits of both the National Fire Protection Association (NFPA 130) and the American Society for Testing and Materials (ASTM E136). This allows Flame Shield® to be in compliance when surface mounted. Epoxy fiberglass conduit is in compliance only when encased in concrete. In addition, Flame Shield® has met the increased temperature and duration demands of the National Fire Protection Association (NFPA 502).

What is the UL 2196 test?

The UL 2196 test is designed to evaluate the performance of electrical circuit protective systems in severe fire events. UL 2196 is designed to evaluate the functionality of electrical circuit systems when exposed to fire for 2 hours followed by the mechanical shock of a fire hose stream. RSCC and Champion Fiberglass partnered to develop a cost-effective solution that would continue to function while being exposed to the severe fire requirements of UL 2196.

Testing concluded that the system as described and installed continued to function throughout the entire test. For a copy of the test report, please contact Champion Fiberglass.
