Manufactured by Xieyu (S.H \/ HIEH), a world-class developer of high-performance thermoplastic flow control, these heavy-duty PPH (Polypropylene Homopolymer) unions are engineered to withstand continuous operating pressures up to 1.25 MPa (181 PSI) and temperatures from -20°C to 100°C.\n\u003c\/p\u003e\n\u003cp\u003e\n  Featuring standard parallel socket depths and a heavy-duty outer union locking nut, this union coupler series is highly compatible with industrial chemical pipelines, acid pickling loops, electroplating lines, waste gas scrubbers, waste acid recovery, and wastewater treatment.\n\u003c\/p\u003e\n\n\u003ch3\u003eThree-Piece Detachable Union Design for Flexible Maintenance\u003c\/h3\u003e\n\u003cp\u003e\n  In continuous industrial pipeline manifolds, joining pipe sections permanently with standard couplings means you must cut and destroy the pipes if a pump, sensor, or valve down the line needs maintenance. Our specialized \u003cstrong\u003eTrue Union Joint\u003c\/strong\u003e features an integrated three-piece design: two symmetrical socket-fusion ends and a central heavy-duty threaded locking collar nut. Inside, a high-flexibility rubber O-ring seal is compressed to secure a watertight mechanical lock. This allows you to easily unscrew the union nut and separate the pipe runs cleanly without any cutting or pipe damage, significantly reducing long-term maintenance costs and pipeline downtime.\n\u003c\/p\u003e\n\n\u003ch3\u003eHigh-Integrity PPH Material Qualities\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChemical \u0026amp; Abrasive Wear Resistance:\u003c\/strong\u003e Molded from high-purity Homopolymer Polypropylene, these S5-rated unions offer superior chemical resistance to highly corrosive media, organic solvents, strong alkalis, and mineral acids.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSafe \u0026amp; Potable Certified:\u003c\/strong\u003e PPH is entirely non-toxic, lead-free, and odorless, making these socket fusion unions completely safe for drinking water pipelines, pharmaceutical loops, and food processing lines.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEasy Molecular Fusion:\u003c\/strong\u003e The smooth, precision-machined internal socket ends are designed for hot-melt fusion welding, forming a unified, leak-proof molecular system.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003e⚠️ Sizing \u0026amp; Socket Fusion Guidelines\u003c\/h3\u003e\n\u003cp\u003e\n  \u003cstrong\u003eNominal pipe dimensions are based on standard outer diameters.

If you need to service an inline pump, instrument, or valve, you would have to cut the pipes. A Union Joint allows you to simply unscrew the central locking nut by hand, cleanly separating the pipe runs without any pipe damage or cutting, making it the essential choice for modular maintenance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can this PPH union joint withstand highly acidic environments?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Yes. PPH Homopolymer offers superior crystalline density, making it exceptionally resistant to pickling acids, waste acids, alkaline wash solutions, and high-purity industrial effluents up to 100°C. It is widely preferred over PVC in tough industrial environments.\u003c\/p\u003e\n\n\u003c!-- Recommended System Bundles \u0026 Cross-Linking (Strictly 3 Links, Chinese placeholders inside href) --\u003e\n\u003cdiv style=\"background-color: #fcfcfc; border: 1px solid #e5e5e5; padding: 15px; border-radius: 6px; margin-top: 30px;\"\u003e\n  \u003cp style=\"margin: 0 0 10px 0; font-size: 15px; font-weight: bold; color: #333;\"\u003eRecommended System Bundles \u0026amp; Companion Products:\u003c\/p\u003e\n  \u003cul style=\"margin: 0; padding-left: 20px; font-size: 14px; color: #555;\"\u003e\n    \u003cli style=\"margin-bottom: 8px;\"\u003e\n      \u003cstrong\u003eFor Flanged Valve Control:\u003c\/strong\u003e To integrate heavy-duty flanged ball valves into your pipeline runs, explore our matching \n      \u003ca href=\"https:\/\/atradesen.com\/collections\/pph-hot-melt-fittings\/products\/s-h-pph-flanged-true-union-ball-valve-s5-1-25mpa-chemical-grade-double-union-bolt-face-valve-1-2-4\" style=\"text-decoration: underline; font-weight: bold; color: #0056b3;\"\u003eXieyu S.H PPH Flanged True Union Ball Valves\u003c\/a\u003e.\n    \u003c\/li\u003e\n    \u003cli style=\"margin-bottom: 8px;\"\u003e\n      \u003cstrong\u003eFor Symmetrical Flange Connections:\u003c\/strong\u003e Bolt these union pipelines securely to metal pumps or tanks using our \n      \u003ca href=\"https:\/\/atradesen.com\/collections\/pph-hot-melt-fittings\/products\/s-h-pph-socket-fusion-one-piece-flange-with-gasket-pp-s5-1-25mpa-chemical-grade-gusseted-flange-adapter-20mm-110mm\" style=\"text-decoration: underline; font-weight: bold; color: #0056b3;\"\u003eXieyu S.H PPH Socket Fusion One-Piece Flanges\u003c\/a\u003e.\n    \u003c\/li\u003e\n    \u003cli style=\"margin-bottom: 0;\"\u003e\n      \u003cstrong\u003eFor Large-to-Small Inline Coupling:\u003c\/strong\u003e Transition your suction pipe runs directly between different sizes using our matching \n      \u003ca href=\"https:\/\/atradesen.com\/collections\/pph-hot-melt-fittings\/products\/s-h-pph-socket-fusion-reducing-coupling-s5-1-25mpa-chemical-grade-hot-melt-pipe-reducer-connector-25mm-110mm\" style=\"text-decoration: underline; font-weight: bold; color: #0056b3;\"\u003eXieyu S.H PPH Socket Fusion Reducing Couplings\u003c\/a\u003e.\n    \u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Atradesen","offers":[{"title":"20mm (DN15)","offer_id":56835835101350,"sku":null,"price":1.56,"currency_code":"USD","in_stock":true},{"title":"25mm (DN20)","offer_id":56835835134118,"sku":null,"price":2.16,"currency_code":"USD","in_stock":true},{"title":"32mm (DN25)","offer_id":56835835166886,"sku":null,"price":3.06,"currency_code":"USD","in_stock":true},{"title":"40mm (DN32)","offer_id":56835835199654,"sku":null,"price":4.56,"currency_code":"USD","in_stock":true},{"title":"50mm (DN40)","offer_id":56835835232422,"sku":null,"price":6.66,"currency_code":"USD","in_stock":true},{"title":"63mm (DN50)","offer_id":56835835265190,"sku":null,"price":8.96,"currency_code":"USD","in_stock":true},{"title":"75mm (DN65)","offer_id":56835835297958,"sku":null,"price":22.56,"currency_code":"USD","in_stock":true},{"title":"90mm (DN80)","offer_id":56835835330726,"sku":null,"price":28.36,"currency_code":"USD","in_stock":true},{"title":"110mm (DN100)","offer_id":56835835363494,"sku":null,"price":50.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0739\/2588\/6118\/files\/S.H_PPH_Socket_Fusion_Union_Joint_S5_1.25MPa_Chemical-Grade_Hot-Melt_True_Union_Coupling_Fitting_20mm_-_110mm_-005.png?v=1784512109","url":"https:\/\/atradesen.com\/products\/s-h-pph-socket-fusion-union-joint-s5-1-25mpa-chemical-grade-hot-melt-true-union-coupling-fitting-20mm-110mm","provider":"Atradesen","version":"1.0","type":"link"}
