Description
Johnson Screen
Johnson Screen mostly refers to V - Wire Water Well Screen.
Welded Johnson Screens are made from V shaped profile wire, which is spirally wound around a cage of longitudinal support rods. Each intersecting point of these wires is fusion welded, with an unique welding process. The pitch of winding gives different spacing between two adjacent turns of wire. This spacing gives passage for water to enter. The entire process is completed on fully computerized machines. Johnson screen offers great strength, precision, long service life and a wide range of applications in the field of process and engineering such as sugar juice filtration, waste water treatment, crude oil and natural gas production and vessel internals solving problems of solid / liquid and solid / gas separation, filtration of oils, greases, paints, food products, water, fuels, liquid cooling agents, chemicals etc.
Advantages including:
Johnson screen has a continuous slot opening which significantly increases the available open area, thus providing greater access to the water bearing zone (the aquifer)
A "V" shaped profile wire which avoids clogging and ensures an uninterrupted flow.
A uniform and efficient well development due to the continuous slot opening.
