1. Small opening diameter: Smaller opening diameter provides finer filtration
2. No additional filter material required: The finished product directly completes the process of adding the filter material, which greatly facilitates the construction.
3. High pipeline strength: Double pipe support, with more resistance to pressure.
4. Tube type thin: The pipe wall is light and convenient for engineering transportation. The pipe wall is thin but the pressure resistance is strong. It is an ideal filter pipe.
