HDPE Butt Fusion 45° Elbow for Siphonic Drainage

Key Features

• Low-Angle Turn: Local loss coefficient significantly lower than 90° elbows; smooth flow transition reduces turbulence and pressure drop.
• Butt Fusion Joints: Flat end faces allow homogeneous fusion with pipes, creating joints with strength equal to the pipe itself.
• Flexible Combination: Two 45° elbows can be combined to create a 90° large-radius turn, further reducing head loss.
• Compact Structure: Shorter lay length than 90° elbows, easier to install in confined spaces.

Production Technology

• Injection molded with precision-controlled wall thickness
• Mold design ensures uniform wall thickness in the bend

Critical Process Parameters

• Control of wall thinning in the bend area (≤10%)
• Angle accuracy: 45° ± 1° between end centerlines

Typical Applications

• Minor slope adjustments in suspended pipelines
• Pipeline offsets to clear small obstructions
• Used with 45° wyes to create streamlined branch entries
• Directional changes in industrial drainage systems

Application Scenarios

• Nodes requiring gradual directional change in siphonic lines
• Commercial building roof drainage systems
• Residential high-rise drainage networks
