divided screen tube and screen plate,they also called V-shape slot filter screen.
The V-shape slot filter screen is made up of rods and profile wire. The rod can be round wire,triangular wire or （wedge）trapezoid wire. The profile wire is triangular wire(V-shaped wire).
The screens have a structure and high open area, as well as accurate slot dimension.At the same time, screen have heat-resisting,anti corrosive,good machine capability,last long,safety and reliability and so on characteristics.Screen
tube with high open area shall favor groundwater infiltration. Abundant water shall reduce the water level’s down,thus to save energy consumption. Under the same condition,high open area can make the speed of groundwater’s entering
into the screen much slower than any other filtration apparatus,which will avoid sand’s entering into screen because of high pressure,thus reduce the abrasion of the pump.Comparatively,groundwater’s entering into screen with higher
open area is much easier than the entering into lower open area screen. The slow water flow shall extend the life span of wells.
The screens are widely used in oil and gas wells, as well as in chemical,mining, paper-making,environmental protection,metallurgy,food,and water purification industries, and the screen plate used in the coal industry.
