HDPE Butt Fusion P-Trap for Siphonic Drainage

Key Features

• 50mm Water Seal: Meets building drainage code requirements, effectively blocking sewer gases and preventing insects from entering indoors.
• Butt Fusion Joints: Both ends are butt fusion compatible, forming a homogeneous monolithic structure with HDPE pipes after fusion, zero leakage.
• P-Type Configuration: Horizontal outlet suitable for connecting to horizontal drain pipes along walls, saving space.
• Smooth Interior: HDPE material provides smooth inner walls resistant to scaling and clogging, ensuring unobstructed flow.
• High Durability: Resistant to chemical attack and environmental degradation.

Production Technology

• Manufactured by HDPE injection molding or pipe bending
• Water seal depth is precisely controlled in the mold
• Both end faces are flat with sufficient clamping length for butt fusion

Critical Process Parameters

• Precise control of 50mm ± 2mm water seal height
• Uniform wall thickness in the bend area to eliminate weak points
• Flatness and perpendicularity of both end faces

Typical Applications

• Trap for sanitary fixtures such as washbasins and sinks in bathrooms
• Odor prevention for air conditioning condensate drain pipes
• Water seal device below floor drains
• Water seal nodes requiring horizontal outlet

Application Scenarios

• Bathroom drainage systems in high-rise buildings
• Commercial kitchen and restaurant drainage
• Hospitals, laboratories, and other high-sanitation areas
