AI Technical Summary
The existing design of U-shaped elbows fails to fully consider on-site construction conditions, resulting in complex installation and insufficient structural strength under high pressure, which may lead to cracking or deformation and poor sealing.
The U-shaped elbow body is made of malleable iron and equipped with pipe clamp components and adjustable clamp structure. The outer surface is coated with an anti-corrosion coating. Combined with rubber fitting gaskets and double pipe clamp design, it enhances structural stability and sealing.
It improves installation efficiency, enhances pressure resistance and service life, adapts to various working conditions, and meets the needs of rapid on-site installation and maintenance.
