Johnson Well Screen
Johnson well screen is also called wedge wire screen or continuous slot screen, which consists of wedge-shape profile wire and the longitudinal support rods. Each intersecting point of these wires is fusion welded. So water well screen has sturdy constriction and good mechanical property. The wedge-shape section plane can avoid blockage, and make sure of the unimpeded water. The consecutive slot have more open area, and water well screen can reduce the speed of the water entering to avoid the sand entering the screen under the great pressure, so wedge wire water well screen pipes can filter sand better. Meanwhile ,the slot can change according to the real condition of the earth.
