Crafted from PE100 grade HDPE certified under EN 12201-1:2024—the latest standard for polyethylene pressure piping—this coupler accommodates pipe sizes from 50mm to 400mm OD, addressing the needs of municipal infrastructure and industrial projects. Rated for 16 bar (232 psi) working pressure at 20°C, it outperforms traditional metal couplings by eliminating corrosion risks and reducing long-term maintenance costs by up to 50%. The one-piece molded design ensures uniform wall thickness with ±0.2mm tolerances, providing consistent performance across all size ranges. Its fusion-welded construction creates a homogenous bond that maintains the full pressure rating of the pipeline system, ensuring a service life exceeding 50 years in buried and above-ground installations .
Designed specifically for butt fusion in sizes ≥110mm and electrofusion for smaller diameters (50-110mm), the coupler forms molecular bonds between pipe ends that eliminate potential leak paths. Butt fusion models feature precision-machined fusion surfaces with alignment markers to ensure proper joint formation. Electrofusion models include embedded resistance wires with barcode-encoded welding parameters that ensure precise temperature control (190±5°C) and cooling times, minimizing installation errors in critical infrastructure projects .
The PE100 material retains 90% of its strength at 40°C, making it suitable for tempered water applications in municipal and industrial systems. It exhibits exceptional creep resistance, maintaining pressure integrity after 10,000 hours of continuous operation at 20°C and 16 bar—equivalent to 50 years of service in typical conditions . The coupler’s flexibility absorbs water hammer shocks up to 25 bar, preventing joint failure in pressure surge scenarios common in large-diameter systems.
Unlike metal couplings that suffer from galvanic corrosion, the HDPE construction provides complete resistance to chlorinated water, soil chemicals, and common plumbing disinfectants. Formulated with 2.5% carbon black additive, it offers superior UV stability for above-ground installations, preventing photo-oxidation in direct sunlight. The material remains flexible at temperatures as low as -40°C and stable up to 60°C, ensuring reliable performance in extreme climates .
This high-capacity fused coupler solves large-diameter connection challenges in:
• Municipal Water Mains: Joins sections of HDPE water distribution pipes in urban expansion projects and pipeline replacement initiatives.
• Wastewater Systems: Connects pressure sewer lines and force mains in municipal wastewater collection networks.
• Industrial Piping: Links large-diameter HDPE process lines in chemical plants, power stations, and manufacturing facilities.
• Water Treatment: Installs HDPE pipelines in desalination plants, reservoir connections, and wastewater treatment facilities .
The coupler is available for pipe sizes from 50mm OD to 400mm OD, with specific models optimized for each size range to ensure proper fusion and pressure performance.
Fusion welding creates a permanent, homogenous bond at the molecular level, eliminating gaskets or threads that are common failure points in mechanical couplings. This provides superior resistance to ground movement and pressure surges .
Sizes ≥110mm require a hydraulic butt fusion machine with temperature-controlled heating plates (190±10°C). Professional certification in large-diameter fusion is recommended to ensure proper joint formation.
Yes. The coupler accommodates standard SDR (Standard Dimension Ratio) variations, including SDR 11 (PN16), SDR 17 (PN10), and SDR 21 (PN6) pipes, making it versatile for system modifications and repairs.
