Product Details

Product Description

Product Description
The Johnson wedge wire screen tubes are manufactured by a v or wedge shaped wire around an internal array of longitudinal support rods. Each intersection point of these wires is fusion welded. The v or wedge shaped profile wire wraps around the support rods over the full length of the screen creating a continuous slot opening,hence the screen allows water (oil) to enter your well freely in ample quantities, while at the same time keeps the majority of sand and gravel out of the well. And the Johnson screens wedge wire screen tubes are popularly used in making of water well screen.
Edge type of wedge wire filter pipe:
1) Standard type: There is no edge on the wedge wire filter pipe.
End ring type. The end rings are welded onto the wedge wire screen cylinder.
2)Flange type. The flange is welded onto the wedge wire screen cylinder and there are two types of flange for your choice.
Features:
1. Screens with the 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 area shall favor groundwater infiltration. Abundant water shall reduce the water level’s down, thus to save energy consumption
3. Reduce the abrasion of the pump 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 entering into the screen because of high pressure, thus reduce 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.
