PPH Steel-Plastic Flanges are widely used in industrial piping systems that require both the excellent corrosion resistance of Polypropylene Homopolymer (PPH) and the high mechanical strength of steel. By combining a PPH flange face with a galvanized or carbon steel backing ring, these composite flanges provide superior structural support, secure bolted connections, and long-term durability under demanding operating conditions.
PPH Steel-Plastic Flanges are extensively used in chemical processing, electroplating, wastewater treatment, pharmaceutical manufacturing, semiconductor facilities, environmental protection projects, and industrial water treatment systems. They are an ideal solution for corrosive media where both chemical resistance and mechanical stability are essential.
