Producr Information
wedge wire screen pipe is used throughout the world for water, oil, and gas wells, and for environmental well completions. It is the dominant screen type used in the water well industry. this type of screen is constructed by winding cold rolled triangular V-shaped wire around a circular array of longitudinal rods. the wire is welded to the rods and produces a rigid unit that has high strength and minimum weight.

wedge wire screens have V-shaped openings that narrowest at the outer face and widen inwardly, thus, oversized particles are retained outside the screen and particles passing through the narrow outside opening can enter the screen

By using a wedge wire screen, savings can be achieved in pumping costs. Lower through-slot velocities mean that pressure drops are minimized, therefore;
Drawdowns are reduced.
Less energy is needed for pumping.
Flow rates are increased.
Less sand in the water reduces wear on the pumps

Technical Parameter
The wedge wire screen can be made in different height and width to address various strength application, meanwhile, the spacing of individual slots can be varied during fabrication if geologic conditions require these variations in a screen's construction
