1.The Water Well Drill Pipe Cylinder is composed of rod strips and V shaped wires
through manufacturing on specialized welding machine.
2.The rib strips and V shaped wires will be welded by resistance welding, has enough
welding strength, equally slot gap, high corrosion resistance, large filter area, good permeability, simple structure
1.Each slot opening of sand control screen between adjacent wires is V-shaped,
resulting from the special shape of the wire used to form the screen surface.
2.The V-shaped opens, designed to be nonclogging, are narrowest
at the outer face and widen inwardly.
3.Continuous-slot Johnson deep well screens provide more intake
area per unit area of screen surface than any other type.
4.For any given slot size, this type of screen has maximum open area.
