Why Polypropylene is Ideal for Chemical Waste Piping Applications
Chemical resistant piping systems are designed to transmit chemical waste to dilution tank or neutralization basin before entering sanitary waste system. The acidity and corrosiveness of the chemical in the waste tank may harm the piping, this is the reason why the material used is very important. The common materials used for chemical piping system are glass, CPVC, polypropylene, and PVDF. Chemical resistant piping system can be found in school laboratories, manufacturing plants, research facilities, and hospitals.
KL Lab had been using polypropylene to produce chemical resistant piping. Polypropylene (PP) is a light weight piping material with very good chemical resistance. When polypropylene is applied in piping system, heat and retardant stabilizers are added to PP to retard flammability and thermal aging. Unlike PVC, PP is also used in many corrosive and high temperature applications. In the market, the PP pipe is available in 20' standard lengths, with the size ranging from ½" to 40". PP is made in schedule 80 and schedule 40 to support different working pressure. It is applied in several usages, such as chemical drainage systems, industrial process, high purity water, hot and cold water distribution, and gravity sewer systems.
