Water Well Drilling 304L Wire Wrapped Johnson Screens China
The v-wire wedge wire screen pipe 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). V-wirewedge wire screen pipes have a robust structure and large open area, as well as accurate slot dimension.
At the same time, V -wire water well screens 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.
Features of stainless steel Johnson Screens
1.Screens with large open area are more suitable for the construction of high-quality
water wells, oil wells and gas wells.
2. Low cost operation
Screens with large open area shall favor groundwater filtration. Abundant water will reduce the water level’s down, thus to save energy consumption.
3.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 screen because of high
pressure, which reduce the abrasion of the pump.
4. Extending the service life of wells
Comparatively, groundwater’s entering into screen with larger open area is much easier than that entering into smaller open area screen.
The slow water flow will extend the service life of the wells.
Advantage of Stainless Steel Johnson Screens Pipe
·Continuous slot opening significantly increases the available open
area, thus providing greater access to the water bearing zone.
· A “V”shaped profile wire avoids clogging and ensures an
· V-wire welded screens have a robust structure and large open area, as well as accurate slot dimension.
· V-wire welded water well screens have the features of easy
backwashing, long service life, high safety and reliability and
