Johnson screen type wedge wrapped wire screen

1.The Johnson wedge wire screen is used throughout the world for water, oil, and gas wells, and for environmental well completions. It is the dominant screen type used in the water well industry.
2.This type of screen made up of rods and warp.the rod can be round wire,triangular wire and trapezoid wire.
3.The wire is welded to the rods and produces a rigid unit that has high strength and minimum weight.
4.The warp is triangular wire(v-shape wire).The water well screens have structure and high open area;as well as accurate slot dimension.
5.Johnson.Wedge wire screen have heat -resising, anti-corrosive,good machine capability,last long, safety and reliability and so on.
