A U-shaped pipe section in P-traps that creates a water seal to prevent sewer gases from entering buildings.
The U-bend section is a critical hydraulic component in plumbing P-traps, featuring a precisely engineered U-shaped configuration that maintains a permanent water barrier. This component functions as a mechanical seal by retaining a specific volume of water in its lower curve, effectively blocking the backflow of sewer gases, vermin, and contaminants while allowing wastewater to flow through via hydraulic displacement principles. Its geometry is optimized for minimal flow resistance while ensuring reliable seal maintenance under varying pressure conditions.

这些分值是采购评估维度示例，不代表真实客户评分、具体国家买家反馈或实时询盘。
According to plumbing codes, U-bends must maintain a minimum water seal depth of 50mm (2 inches) to effectively block sewer gases under normal pressure differentials.
Larger diameters (≥100mm) reduce flow velocity, increasing sedimentation risk, while smaller diameters (<50mm) may cause excessive turbulence and seal loss. Optimal diameter depends on flow rate and solid content.
No, U-bends must maintain vertical orientation to ensure proper water seal formation. Horizontal installation compromises the hydraulic barrier and violates plumbing standards.
