characteristics1. Water Well screens are manufactured with V-shaped profile wire which is spirally wound around a cage of longitudinal support rods.The "V" or wedge shaped profile wire wraps around support rods over the full length of the screen creating a continuous slot opening, hence the screen allows water (oil) to enter your well freely in ample quantities, while at the same time keeps the majority of sand and gravel out of the well.2. Continuous slot: opening significantly increases the available open area. Providing greater access to the water-bearing zone.3. Non clogging: "V" shaped profile wire, avoids clogging, is self-cleaning and ensures an uninterrupted flow. Sand grains make only two point contact and don't wedge in the screen's inwardly enlarging slot.4. Large Open Area: This allows more water to enter at much lesser frictional head loss and the efficiency of well is improved appreciably.Johnson treatment of the company—-a brilliant century Company financial saving,innovative and flexible and integrated,providing a wide range of diverse foms Industrial Water Treatment of solutions,applicable to different areas of the supply of efficient,durable Products,the implementation of maintenance-free policy.

Material: Low carton,low carton galvanized steel (LCG),steel treated with plastic spraying,stainless steel (304, 302, 304L, 316, 316L stainless steel wire, or galvanized steel wire.)2. Length: lengths up to 6 meters.3. Diameter ranging from 25mm to 800mm4. End connection: Plain beveled ends for butt welding or threaded.Johnson screens consist of V-shape profile wire and the longitudinal support rods. 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. The consecutive slot have more open area, and it can reduce the speed of the water entering to aviod the sand entering the screen under the great pressure, so it can filter sand better. Meanwhile, the slot can change according to the real condition of the earth.
