Stainless Steel Screen Pipe

Description

Johnson water well screen consists of V-shape profile wire and the longitudinal support rods. Each intersecting point of these wires is fusion welded. So this quality screen 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 avoid the sand entering the screen under the great pressure. So it can filter sand better. Meanwile, the slot can change according to the real condition of the earth.

It is widely used throughout the world for water, oil, and gas wells, and is the dominant screen type used in the water well industry.

Specification

Technical parameters of Screen pipe

Character:

1. Screens with high open area are more suitable for the constructioni of high-quality water wells, oil wells and gas wells.
2. Low cost operation Screens with high open area shall favor groundwater infiltration. Abundant water shall reduce the water level’s down, thus to save energy consumption.
3. Reduce the abrasion of the pump under the same condition, high open area can make the speed of groundwater’s entering into the screen much slower than any other filtration apparatus, which will avoid sand’s entering into screen because of high pressure, thus reduce the abrasion of the pump.
