Polyvinyl Chloride or PVC is a flammable material with a melting point of 160 degrees C. Melting begins at about 140 degrees C. The building code does not allow PVC piping to be used as a dryer vent because it can catch fire at fairly low temperatures. The Uniform building code is written for safety considering the worst case scenario...like when the vent pipe gets blocked....a child shoves a Coke can into the vent...etc. PVC is used on some high efficacy furnaces and water heaters because the exhausting gasses are cool by the time the get to the PVC pipe. Please don'the risk burning your house down by using dryer vent materials that are not code approved and US approved for dryer vent use.
