The Black HDPE 45° Elbow is a specialized fitting designed to optimize rainwater drainage systems with its precise angle and high-density polyethylene (HDPE) construction. Unlike 90° elbows that can cause flow restriction, the 45° angle reduces turbulence and pressure loss, ensuring efficient water flow in rain gutters, downspouts, and stormwater pipelines. Its black color contains carbon black additives that enhance UV resistance and heat stability, making it ideal for outdoor and underground installations. Available in sizes from 32mm to 250mm OD, this elbow meets EN 1519 standards for drainage systems, combining flexibility, durability, and cost-effectiveness for both residential and municipal rainwater management .
The 45° angle minimizes flow resistance compared to sharper elbows, reducing the risk of clogs from leaves, debris, and sediment in rainwater systems. The smooth inner wall (Ra <0.01mm) further enhances drainage efficiency, allowing water to flow at higher velocities without turbulence.
Formulated with 2–3% carbon black additive, the HDPE material resists UV degradation, ensuring long-term performance in direct sunlight. This protection extends to chemical resistance against acidic rain (pH 4–6) and soil contaminants, making it suitable for underground installations where corrosion destroys metal fittings . The elbow retains flexibility in temperatures as low as -40°C, preventing cracking in freezing conditions, and remains stable up to 95°C .
Manufactured from PE80/PE100 grade HDPE (per IS 14333), the elbow withstands external pressure from soil and traffic loads, making it suitable for buried stormwater lines. Its one-piece molded design eliminates weak points, with impact resistance sufficient to survive accidental backfilling damage during installation. The material’s flexibility allows minor ground movement without cracking, a critical advantage in earthquake-prone areas.
This elbow is indispensable in rainwater management systems:
Residential Drainage: Connects gutters to downspouts and directs rainwater away from foundations, preventing flooding.
Municipal Stormwater Systems: Links underground pipelines in streets and parks, handling large volumes of runoff during heavy rains .
Industrial Sites: Manages roof drainage in factories and warehouses, withstanding exposure to industrial pollutants in rainwater.
Infrastructure Projects: Used in bridge and overpass drainage systems, where UV resistance and impact strength are critical .
The 45° angle reduces flow turbulence and pressure loss, allowing debris-laden rainwater to pass through without clogging. This minimizes maintenance needs compared to 90° elbows, which often trap leaves and sediment.
Yes. The PE100 HDPE construction withstands soil pressure and chemical exposure, making it ideal for buried stormwater lines. It is often installed using trenchless technology to minimize surface disruption.
The carbon black additive in the HDPE blocks UV radiation, preventing material degradation in outdoor applications. It also absorbs heat, reducing condensation in cold weather and preventing ice buildup in winter.
Sizes range from 32mm to 250mm OD, matching standard rainwater pipe diameters. Selection depends on the expected flow volume: smaller sizes (32–63mm) for residential use, larger sizes (110–250mm) for commercial or municipal systems .
