PPH Pipe Fittings

PPH pipe fittings are manufactured from polypropylene homopolymer (PPH), a high-crystallinity plastic prized for its outstanding chemical resistance and rigidity, making it a preferred material for corrosive fluid handling where standard PPR is not suitable. As a specialized PPH pipe fittings supplier, we produce threaded and union-style fittings designed for demanding chemical and industrial environments.
PPH fitting range covers three main types: threaded elbow and tee fittings for directional and branch connections in threaded piping runs; threaded coupling fittings (female and male thread) for straight-line pipe-to-pipe or pipe-to-equipment connections; and union fittings, including universal unions and union connectors, which allow sections of pipe to be quickly disconnected for maintenance without cutting the line. All PPH fittings share the base material's key characteristics: strong resistance to acids, alkalis, and organic solvents, higher rigidity and load-bearing capacity than standard polypropylene, good resistance to stress cracking, and stable performance across a wide temperature range.
Main applications include acid/alkali waste drainage, chemical dosing and process lines, laboratory and electroplating plant piping, and industrial ventilation ducting. Industries served include chemical processing plants, electroplating and metal-finishing facilities, laboratories, semiconductor and electronics manufacturing, and wastewater treatment — any setting that requires pipe fittings capable of withstanding aggressive chemical media.
