Stainless Steel 304l 14" Johnson Wire Screen For Water Well Drilling
Stainless Steel 304L Well Screen For Water Well Drilling
Well Screen , also called Water well screens, Vee wire well screens, are made of V or wedge shaped wires around an internal array of longitudinal support rods. It is designed to serve as the intake portion of wells constructed in unconsolidated or semi-consolidated aquifers. This design supplies a continuous slot openings, which allows water to enter the well freely in ample quantities and keeps the majority of sand and gravels out of the well at the same time.

Advantages of Well Screen:
1.Better filter function. The V-shape section plane of well screens(Johnson screens) creates the continuous slot, which can avoid blockage and make sure of the unimpeded water.
2. Prolong life of well. The consecutive slot of well screens(Johnson screens) have wider open area, and it can reduce the speed of the water entering to avoid the sand entering the screen under the great pressure, so it can control sand better, which can increase the water yield and prolong service time of the well.
3.Long service life. Wire and support rods are all-welded, which makes well screens(Johnson screens) more robust and longer life.
4.High pressure-resistant. The longitudinal support rods and the continuous slot make the well screens(Johnson screens) have more excellent pressure-resistant performance.
5.Customized. Specifications and end connections of well screen(Johnson screens) can be fabricated according to customers' requirements.
