![]() Why You Need Corrosion Resistant Electrical Conduit ![]() For specific applications which are not covered in this guide, and may require screening tests to evaluate resin system suitability, consultation with Champion Fiberglass is recommended.) (The information provided in the epoxy chemical resistance chart is to be used solely as a guide since it is impossible to anticipate all individual site conditions. ![]() A very severe test, it has been shown that Champion Duct® can often be used for chemicals listed as “Not Recommended” (NR) as real cases often are limited to fumes, vapors and occasional splashes at the temperatures indicated. The corrosion guideline tests were performed by immersing epoxy coupons for 30 days in each chemical at designated temperatures. Our Chemical Resistance Guide documents epoxy chemical test results in a chart format. This process ensures that fiberglass conduit comprised of epoxy resin is much more corrosion resistant than PVC conduit and polyester and vinyl ester resins.įiberglass Chemical Resistance Guide Illustrates Corrosion Testing ResultsĬhampion Fiberglass Ⓡ conduit has been tested with strict protocols against hundreds of chemicals. They are then cured under high temperature, creating a conduit product with flexural strength that also resists chemicals and corrosion. The strands are laid in a precise pattern and impregnated with epoxy resin as they are wound onto a straight mandrel. Fiberglass conduit is created by tension-winding strands of fiberglass over a rotating mandrel. This is due in part to its unique fabrication processes. Fiberglass conduit is a wise choice for harsh, challenging environments because of its epoxy chemical resistance. Made in the USA, fiberglass electrical conduit is available now with shorter lead times and lower prices than PVC SCH 40 conduit. Plus, it is not subject to the current PVC shortage. While PVC electrical conduit is often the choice for corrosive environments, fiberglass conduit provides similar chemical protection. Depending on the project needs, conduit types to choose from include galvanized rigid steel (GRC), PVC SCH 40, PVC SCH 80, PVC-coated steel, aluminum conduit and epoxy fiberglass conduit. Simply put, electrical conduit chemical resistance equals corrosion protection.Ĭorrosion-Resistant Electrical Conduit with Shorter Lead Times, Lower PricesĮngineers and contractors have a wide array of electrical conduit materials to select from for industrial projects. Think of chemical resistance as strength to resist a chemical attack. In industrial construction, there’s exposure to thousands of chemical compounds, and some of the more common include saltwater, petrochemicals and bleach. Subsequently, a compromised conduit and cable system has the potential to impact municipal water supplies.Ĭhemical resistance is the ability of a material to resist the destructive properties of harsh compounds without degrading. If electrical conduit does not provide ample chemical resistance, it fails to provide corrosion protection, leaving the conduit, wire and cable subject to compromise. With extreme chemicals and unrelenting temperatures, it's a damp and caustic environment with maintenance and construction that demands durable materials. ![]() In the US, close to 15,000 wastewater treatment plants provide the critical infrastructure required to maintain public health. ![]() Conduit provides mechanical protection, and caustic environments demand corrosion protection through chemical resistance. As a building material, electrical conduit is used in a wide range of applications across industrial construction, from bridges and data centers to utilities and wastewater treatment plants, where it serves to organize and protect cables and wires in raceways. ![]()
