Environmentally friendly AIPPR Standard IGC351-18 from Pipe Lining Supply provides for the noninvasive rehabilitation of drain, waste and vent piping in sizes of 1.5- through 15-inch-diameter pipe. The process uses non-VOC polyurea resin applied to cast iron, galvanized, clay, PVC, and ABS piping to seal leaks, prevent future scale from forming, and restore the pipe to a new 50-year design life. The resin is applied by brushes that serve two purposes: to mix the resin where it is delivered in the pipe and to spread it over the surface of the pipe by applying a 1/2 mm of material per coat, allowing the applicator to build to a design thickness to achieve the quantity needed for the rehabilitation. A 50-linear-foot line can be coated to a 3 mm thickness in about an hour from start to finish. 888-354-6464; www.pipeliningsupply.com.
