Johnson Slotted Water Well Screen Pipe
Well Screen Pipe
 Can be fully customized to meet any specific
well application. They feature strong assemblies,
are resistant to erosion, and cannot be plugged
by fines or produced solids.
 An exclusive slip-ring design isolates the water
well screent from mechanical loads applied to
the screen assembly; i.e., compression, tension,
or torque, while maintaining efficient sand
control.
 The typical screen unit arrangements are 32 ft
of jacket on 38 ft of base pipe and 16 ft of
jacket on 20 ft of base pipe, but any length of
handling area for torque tongues can be ordered. The protective shroud can be perforated
or louvered and is designed to accommodate a fiber-optic cable.
 The first three digits of these codes designate the width of the wire in thousandths of one
inch, and the last three digits designate the height, also in thousandths of one inch. The wire
is available in either stainless steel material or Alloy or carton steel material
 For special applications, direct wrap (also known as shrink fit) can be made available with
the same metal options as the slip-on wrap. In this case, the longitudinal ribs are mounted
to the base pipe, and the jacket is wrapped and welded directly over this assembly,
providing a very tight shrink fit. This process eliminates the requirement of welding to the
base pipe, while creating a base pipe and jacket arrangement that behaves like a single part.

Well Screen Pipe Characteristics
 A continuous slot opening which significantly increases the available open area, thus
providing greater access to the water-bearing zone.
 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.
 Ladder-like wire welded screens have a strong structure and high open area, as well as an
accurate slot dimension.
 5. Ladder-like wire welded screens have the features of easy backwashing, last long, safety,
and reliability as well as low comprehensive cost.
 Compared with the perforated tube, the wedge wire screen filter element is more suitable
for application in the filter equipment with many impurities and backwash required.
Features of Well Screen Pipe
 Screens with the large open areas are more suitable for the construction of high-quality
water wells, oil wells, and gas wells.
 Low-cost operation
Screens with large open area shall favor groundwater filtration. Abundant water will reduce
the water level’s down, thus saving energy consumption.
 Under the same condition, large open area can make the speed of groundwater’s enter into
the screen much slower than any other filtration apparatus, which will avoid sand entering
into the screen because of high pressure, which reduces the abrasion of the pump.
 Extending the service life of wells
Comparatively, groundwater entering into a screen with the larger open area is much easier
than that entering into smaller open area screens.
 The slow water flow will extend the service life of the wells.
