Standard wedge wire wrapped screen pipe (external circumferential wire and axial internal support rods) with smooth external screen is a kind of strainers that flow from outside to inside filtration.
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.
The different types of wedge wire filter pipe:
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.

Advantages
1. The application of wedge wire on the filter element forms a V-shaped opening between the gaps of the screen tube. Due to the inherent advantages of the design, it can operate more efficiently than other types of filtration products, not only ensuring the smoothness of water resource filtration, but also the flow rate of the wedge wire filter pipe is three times that of the bridge filter pipe in terms of working efficiency. 9 times the slit water filter!
2. Structural advantages of wire winding. The arrangement of the longitudinal support rods according to actual needs and the form of the continuous gap of the screen tube make the product more
High compression resistance. The T-shaped wire and all longitudinal support rods are combined by electric welding, which is sturdy and durable, with a longer working life cycle and low comprehensive cost.
3. Large gap in the filter tube. Any sieve tube gap size with a gap between 0.02mm-60mm can be made according to actual needs to meet different application conditions.
4. The winding wire and all supporting wires are connected by electric welding, which is strong and durable, and the working life cycle is longer.
5. The longitudinal arrangement of the support wire and the form of the continuous gap of the screen tube according to the actual needs make the product have higher compression performance.
6. The advantages of this product have improved the working efficiency and service life of the well, making this product a leader in water filtration equipment.
Screen pipe connection:
Because the wedge-shaped filter tube is welded with metal wire, it can be connected by various connectors such as flange and electric welding. Wide application range and low comprehensive cost.
