HDPE Butt Fusion 90° Bend with Cleanout for Siphonic Drainage

Key Features

• Back Cleanout: Located on the outer radius, aligned with the downstream straight pipe for direct access by cleaning tools.
• Butt Fusion Joints: Both ends fuse homogeneously with pipes, creating a monolithic structure.
• Large-Radius Flow Path: Maintains low-resistance turn while integrating maintenance functionality.
• Integral Injection Seal: Cleanout port is molded as one piece with the bend body, eliminating leak paths.

Production Technology

• Complex injection molding forming the large-radius bend flow path and cleanout channel in one shot

Critical Process Parameters

• Control of wall thickness uniformity at the intersection of cleanout port and bend flow path
• Threaded area dimensional accuracy and plug sealing performance

Typical Applications

• 90° turns in siphonic systems where the downstream pipe run is long and prone to blockage
• Turn at the base of a vertical stack transitioning to horizontal discharge (critical maintenance point)
• Locations where a suspended pipe makes a right-angle turn and a cleanout is required

Application Scenarios

• Smooth bottom turns with maintenance access in large public building siphonic pipelines
• Airport, stadium, and exhibition hall drainage systems
• Commercial complex drainage networks
