Wedge wire screen pipe is widely used throughout the world for water, oil, and gas wells, and is the dominant screen type used in the water well industry. Wedge wire screen pipe is made by winding cold-rolled wire, approximately triangular in cross section, around a circular array of the longitudinal rods. The wire is attached to the rods by welding, producing rigid one-piece units having high strength characteristics at minimum weights. Slot opening for continuous-slot screens are manufactured by spacing successive turns of the outer wire to produce the desired slot size. All slots should be clean and free of burrs and cuttings. Each slot opening between adjacent wires is V-shaped, from the special shape of wire used to form the screen surface. The V-shaped openings designed to be non-clogging, are narrowest at the outer face and widen inwardly;

Types of wedge wire filter pipe:

Flanges and reinforcement rings are available depending on the application.

1. Screens with a high open area are more suitable for the construction of high-quality water wells, oil wells, and gas wells.
2. Low-cost operation Screens with high open areas shall favor groundwater infiltration. Abundant water shall reduce the water level’s down, thus saving energy consumption
3. Reduce the abrasion of the pump Under the same condition, a 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 entering into the screen because of high pressure, thus reducing the abrasion of the pump.
4. Extend the life span of wells Comparatively, groundwater’s entering into a screen with a higher open area is much easier than entering into a lower open area screen. The slow water flow shall extend the life span of wells.
