This is a demonstration of the comparative flammability of polypropylene pipe (PP), reinforced concrete pipe (RCP), and high density polyethylene pipe (HDPE). Dry hay is ignited in three 18 in. by 18 in. pipes and allowed to burn. This is an unedited test conducted on October 21, 2015.

  1. Great demo! I recall many? Years ago that one child died when a fire started in an ashaltic lined CMP caught on fire. The pipe access was when it discharged to a concreted channel. Happened in Tucson, AZ. Kids were playing in the pipe.

  2. I see you guys are ready for ISIS. Great Job showing us the danger that exists.
    Must be a slow day at the pipe plant.
