Continuous Slot Stainless Steel Wire Wrapped Casing Johnson Wire Screen
Johnson Wire Screen Description
Stainless Steel Wire Wrapped Casing Johnson Wire Screen is made up of rods and warp.
The rod can be round wire, triangular wire or trapezoid wire.The warp is triangular wire (V-shaped wire).
The welded ring sand control Water Well Screen Casing have a robust structure and large open area,
as well as accurate slot dimension.
At the same time, The Water Well Screen Casing have many advantages such as heat-resisting,
anti-corrosive, good machine capability,long service life, safety and reliability and so on.
It can be used in many kinds of medium filtering.

Johnson Wire Screen Characteristics
►V-Shaped Slots: Openings shaped like a "v" that open toward the inside of the well tend to allow the
particles that are just barely smaller than the width of the slot pass. In other shapes of openings,
these particles would get caught in the screen and clog it.
►Continuous Slots: The special design gives continuous slot opening across the periphery and
length of screen.
►Very Large Open Area: This design gives continuous slot and hence the% open area for water to
enter is more than 2 times that of conventional slotted pipes of any size and slot opening.
This allows more water to enter at much lesser frictional head loss and the efficiency of
tube well is improved appreciably.
►Better Sand Filtration: Due to specialize manufacturing process, wide range of slot opening
is available down to 0.15mm to allow proper slot selection depending upon the size of sand in
particular area. This gives better sand control and reduced pump maintenance and longer tube well life.
►Energy Saving: Due to reduce frictional head losses and increased discharge, the pump load reduces
the power required to pump same quantity of water. Power saving of around 20-25% is observed.
Johnson Wire Screen Application:
