PVC Pressure Pipe Fittings & Flanges
Polyvinyl chloride, or PVC, pipe fittings and flanges connect with pipe to transport potable water, corrosive liquids, and sewage in industrial and commercial applications. Pressure-rated fittings have a numbered schedule rating. The higher schedule number indicates a thicker, stronger wall to handle higher pressures. Schedule 80 fittings have thicker walls than Schedule 40, but not as thick as Schedule 100. PVC is a strong thermoplastic that resists ultraviolet (UV), acids, alkalis, oils, and many corrosive inorganic chemicals, making it resistant to the corrosive effects of sewage. Lightweight PVC is nonflammable with good electrical insulation properties, and its smooth interior walls resist scaling. PVC fittings and flanges come in a variety of shapes and sizes.
