Johnson screens(V-shape wire slot screen pipe) Johnson screens consist of V-shape profile wire and the longitudinal support rods. Material: carbon steel and stainless steel (302,304,304L,316,316L etc). Each intersecting point of these wires is fusion welded. So it has sturdy constriction and good mechanical property. The V-shape section plane can avoid blockage, and make sure of the unimpeded water. Providing more open area, these non-plugging well screens have a tight slot tolerance, effective sand control and a lower entrance velocity. so it can filter sand better. We can produce length up to 20’ (6.096m), Meanwhile, the slot can change according to the real condition of the earth.
