PPH Backing Rings are important components for flange connections in industrial thermoplastic piping systems. They are typically used together with PPH stub ends or flanges to provide mechanical support and distribute bolt loads evenly across the connection. Manufactured from high-performance Polypropylene Homopolymer (PPH) or used as part of a steel-plastic flange assembly, backing rings help create stable and reliable pipeline connections.
PPH Backing Rings are widely used in chemical processing, wastewater treatment, electroplating, pharmaceutical manufacturing, semiconductor production, environmental engineering, and industrial water treatment. Their corrosion resistance, dimensional stability, and compatibility with thermoplastic piping make them suitable for demanding industrial environments.
