The PN16 PPH union tees are high-performance piping components engineered for precise corrosive fluid handling in industrial systems. Manufactured from high-purity polypropylene homopolymer (PPH) via advanced extrusion and injection molding processes, these corrosion resistant PPH tees deliver exceptional durability and reliability in harsh operating environments. The union design features a detachable middle section, enabling quick disassembly, inspection, and maintenance without cutting pipelines. Rated for PN16 (16 bar) at 20°C, these industrial PPH pipe tees ensure leak-free connections even under frequent pressure fluctuations, making them indispensable for critical fluid transfer applications.
Our PPH tee fittings undergo rigorous testing to withstand 98% sulfuric acid, 50% sodium hydroxide, and chlorinated solvents for over 10,000 hours without measurable weight loss or structural degradation. They outperform 316 stainless steel in chloride-rich environments, eliminating the risk of corrosion-related failures and reducing replacement costs.
Operating reliably from -20°C to 100°C, these high pressure PPH tees maintain structural stability under 16 bar working pressure, with a burst pressure exceeding 48 bar — three times the maximum operating pressure. Their low thermal expansion coefficient (≤100×10⁻⁶/°C) minimizes dimensional changes during rapid temperature cycles, preventing joint loosening and leakage.
The union design allows for tool-free disassembly of individual sections, cutting maintenance time by 50% compared to welded tees. They support both socket fusion welding for permanent connections and mechanical union joints with EPDM gaskets for removable setups, offering flexibility for different installation requirements.

For permanent installations, use socket fusion welding at 260°C ±5°C following EN ISO 10931 guidelines. Allow 3-5 minutes of cooling time for 2" diameter pipes to ensure seamless, leak-proof bonds. For removable connections, tighten union nuts evenly to avoid gasket distortion. These tees are fully compatible with metal pipes via ISO 7-1 threaded adapters with PPH-to-metal transition joints, preventing galvanic corrosion.
