Stainless Steel Screens
Well screen performance is depended on several factors, including
wire and rod shape, construction, steel grade and micro structure,
as well as slot accuracy over the full length of the screen. To
meet the most demanding requests, Johnson type Screens continues to
engineer and manufacture stainless steel screens from 2 ft / 0.7 m
to 40 ft. / 12.2 m. In recent years, we have more than doubled our
manufacturing capacity by adding new equipment and expanding our
Johnson type stainless steel well screens can be constructed out of
304, 304L, 316L and 302 stainless steel. Other corrosion-resistant
alloys are available upon request.
Made of V-shape profile wire and longitudinal support rod, each
intersecting point of the wires is fusion welded, so it has sturdy
constriction and good mechanical property.
The V-shape section can avoid blockage and make sure of the
unimpeded water. And the continuous slot have flexiable open area,
that can reduce the speed of the water entering to avoid the sand
entering the screen under the pressure, so it can filter sand
And also the slot size can changed according to different
It is widely used for water, oil, and gas wells, and is the
dominant water well screen used in the water well industry.
