The Light Blue PP 90° Elbow for Water Supply is a precision-engineered plumbing fitting designed to create smooth 90-degree turns in residential, commercial, and irrigation water distribution systems. Manufactured from high-strength PP-R copolymer compliant with ASTM F2389-24a and NSF/ANSI 61 standards, this elbow provides a pressure-resistant turn that minimizes flow disruption while maintaining system integrity. Its distinctive light blue color enables quick identification of water supply lines, simplifying system maintenance and compliance verification in complex plumbing networks .
Available in sizes from 20mm to 110mm OD, the elbow maintains 10 bar (145 psi) working pressure at 20°C, with stable performance at 6 bar (87 psi) for water temperatures up to 60°C. The one-piece molded construction eliminates potential leak paths, while the optimized internal radius (1.5× pipe diameter) reduces pressure loss to less than 4% at design flow rates—verified through computational fluid dynamics (CFD) analysis. With a service life exceeding 50 years in both above-ground and buried installations, it outperforms metal elbows by eliminating corrosion and scaling issues .
The elbow features a long-radius design with a smooth internal curve that minimizes turbulence and pressure loss at the turn, maintaining consistent flow rates through the system. The inner surface finish (Ra <0.01mm) prevents sediment buildup and biofilm formation, ensuring water quality in potable systems. CFD simulations confirm that pressure loss remains below 4% across all size ranges at flow velocities up to 2 m/s .
Formulated with 2% UV stabilizers and heat-resistant additives, the PP-R material maintains flexibility and strength in temperatures ranging from -10°C to 70°C, preventing cracking in extreme conditions. It exhibits exceptional chemical resistance to chlorinated water, disinfectants, and mineral deposits commonly found in municipal water supplies. The material’s impact strength (10 kJ/m² at 23°C) exceeds industry standards, resisting damage during installation and operation .
Designed for socket fusion installation, the elbow features precision-machined fusion sockets with clearly marked heating indicators (260±10°C) and insertion depth lines. The fusion zones are reinforced with 20% thicker walls to maintain pressure integrity at the critical bend area. Post-fusion testing shows joint strength exceeding the parent pipe strength by 15%, ensuring leak-free performance even under system pressure fluctuations .
This hydraulic-efficient elbow solves directional challenges in diverse water supply scenarios:
• Residential Plumbing: Creates turns in cold and hot water lines in kitchens, bathrooms, and utility rooms of homes and apartments.
• Commercial Buildings: Manages water flow direction in hotels, hospitals, and office complexes with high-volume water demands.
• Irrigation Systems: Directs water flow in agricultural, landscape, and greenhouse irrigation networks, maintaining pressure across turns.
• Municipal Service Lines: Connects main water lines to residential and commercial service connections with minimal pressure loss .
Long-radius elbows (1.5× pipe diameter) reduce pressure loss by up to 60% compared to standard short-radius elbows, maintaining better flow rates and reducing energy consumption for pump systems .
Standard sizes include 20mm, 25mm, 32mm, 40mm, 50mm, 63mm, 75mm, 90mm, and 110mm OD, matching common pipe dimensions in residential and light commercial plumbing systems.
Yes. The PP-R copolymer material is certified to NSF/ANSI 61 standards for potable water contact, ensuring no leaching of harmful substances into drinking water supplies .
Absolutely. It maintains full pressure rating at ambient temperatures and is rated for 6 bar working pressure at 60°C, making it suitable for both cold water lines and tempered hot water applications up to 60°C .
