Manufactured from PE100 grade HDPE—the material of choice for pressurized water applications under EN 12201-1:2024—this coupler creates permanent, homogenous joints that eliminate leakage risks associated with mechanical fittings. Available in size combinations from 20mm×16mm up to 315mm×250mm, it provides a seamless flow transition between main lines and service connections, maintaining hydraulic efficiency in municipal, commercial, and industrial water networks. Its fusion-welded design ensures a service life exceeding 50 years, outperforming traditional metal reducers that suffer from corrosion and leakage over time.
The coupler is designed for electrofusion or butt fusion installation, creating molecular bonds between the fitting and pipes that are stronger than the pipe material itself. This eliminates potential leak paths found in threaded or gasketed fittings, reducing maintenance costs over the system’s lifetime. The fusion process is controlled via barcode-scanned parameters, ensuring consistent joint quality across installations .
Featuring a gradual diameter transition with a 5° taper angle, the coupler minimizes pressure loss and turbulence, maintaining flow rates within 3% of straight pipe performance. The smooth inner surface (Ra <0.005mm) prevents scaling and bacterial growth, critical for maintaining water quality in potable systems. Computational fluid dynamics (CFD) analysis ensures optimal flow characteristics across all size combinations.
Certified for 16 bar (PN16) working pressure at 20°C, the coupler meets the demands of medium-pressure water supply systems. It retains pressure integrity at temperatures up to 40°C (common in warm climate water mains) and exhibits creep resistance under sustained pressure—maintaining 90% of its strength after 10,000 hours of continuous operation .
This fused reducing coupler excels in water supply transition scenarios:
Municipal Distribution: Connects large-diameter main lines to smaller service lines in urban water networks.
Industrial Facilities: Transitions between process water mains and equipment supply lines in manufacturing plants.
Commercial Complexes: Reduces pipe size from building main lines to floor distribution systems in hotels and shopping centers.
Water Treatment: Links filtration system outlets to distribution mains, maintaining pressure through diameter transitions .
Fused joints create a homogenous bond between fitting and pipe, eliminating leakage risks and providing better resistance to ground movement, temperature fluctuations, and pressure surges compared to mechanical couplings.
Electrofusion models include barcode-encoded welding parameters that are scanned by fusion equipment, ensuring precise temperature and pressure control during installation. This minimizes human error and guarantees consistent joint quality.
Yes. The PE100 HDPE material meets EN 12201-1 requirements for potable water contact, with no leaching of harmful substances and resistance to bacterial growth on inner surfaces.
The coupler is available in standard size reductions including 20mm×16mm, 32mm×25mm, 63mm×50mm, 110mm×90mm, 200mm×160mm, and 315mm×250mm, covering most water supply transition needs. Custom sizes can be manufactured for specialized applications.
