Johnson screens are used for oil and water exploiting.They consist of Vshape profile wire and the longitudinal support rods. Each intersecting pointThe Vshape 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 of these wires is fusion welded ,so it has sturdy constriction and good mechanical property. Avoid 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.
Advantage:
1. OD(outside diameter):usually 6-5/8" 7" 8-5/8" 9-5/8" 10-3/4" 12" 12-3/4" by our customers' requirements.
2. Material:carbon steel or stainless steel(201,304,304L,316, 316L)
3. Slot size:given by customers. We can do 0.05-2mm.
4. Open area:a maximum open area of 60% is offered facilitating high flow capacity and low inlet resistance resulting in extended well life.
5. Wire and rod dimensions:obtained through well depth, or collapse strength and tensile strength, which are furnished by customers.
6. Connection types:usually STC threads or a passage of welded ring ( plainend or beveled end), both of them are welded together with the portion of screen
