Product description of Continuous slot 8-5/8" water well drilling wire wrapped screens
Continuous slot wire wrapped screens are made by winding cold-rolled wire,approximately triangular in cross section, around a circular array of the longitudinal rods. The wire is attached to rods by welding, producing rigid one-piece units having high strength characteristics at minimum weights. Advantages of the flat welded Johnson type screens/the water well screens/wedge wire screens are as follows:
- Better filter function. The V-shape section plane of flat welded Johnson type screens/water well screens/wedge wire screens creates the continuous slot, which can avoid blockage and make sure of the unimpeded water.
- Prolong life of well. The consecutive slot of flat welded Johnson type 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.
- Long service life. Wire and support rods are all-welded, which makes flat welded Johnson type screens/water well screens/wedge wire screens more robust and longer life.
- High pressure-resistant. The longitudinal support rods and the continuous slot make flat welded Johnson type screens/water well screens/wedge wire screens have more excellent pressure-resistant performance.
- Customized. Specifications and end connections of flat welded Johnson type screens/water well screens/wedge wire screens can be fabricated according to customers’ requirements.
