The ASTM Standard UPVC 90° Elbow is a heavy-duty directional fitting engineered to execute sharp, precise 90° turns in piping layouts while maintaining system pressure and hydraulic efficiency. Designed to absorb stress concentrations caused by thermal movement and fluid impulse, this elbow offers exceptional structural stability across indoor and outdoor piping systems.
Technical & Design Advantages:
Hydrodynamic Flow Geometry: Smoothly contoured interior curvature minimizes turbulence and head loss, reducing overall pumping energy requirements for long-distance water transmission.
Heavy-Wall Stress Resistance: Reinforced wall thickness at outer bend zones effectively counteracts water-hammer shocks and sudden pressure spikes.
Advanced UV & Weather Resistance: Formulated with premium UV stabilizers and titanium dioxide to prevent plastic degradation, color loss, and embrittlement under direct sunlight exposure.
Applications:
HVAC chilled water loops and industrial cooling towers.
Swimming pool filtration and water feature circulation lines.
Residential plumbing and underground supply lines.
Water treatment and reverse osmosis plant piping.
