Wedge Wire screen cylinders / filter drum / Rotary Drum Screen
Product Name: v wire water well screen, wire wrapped screen pipe,
Johnson specialty screen, spiral screen tube, strainer pipe, rod
based continuous slot wedge wire screen, drilling well screen,
reversed rolled slot well screens, screen cylinders,
continuous-slot well screen, Well screen, water filter, filteration
Wedge Wire screen cylinders can be designed with slot openings and
wires running radially on the outside surface of the screen
cylinder (above left) or they can be positioned axially on the
inside of the cylinder (above right) Screen cylinders are
manufactured in various diameters from 1/2" pipe size to 35"
Screen cylinders (above right) can be fabricated into larger
diameters. Each intersection of wedge wire and support rod is
welded for strength and durability.Various wedge wire and support
rod combinations can be used to produce the best screen design.
Rotary Screens typically use wedge wire for the screening media.
The above externally fed unit has a spiral wound wedge wire screen
drum 36" OD x 120" long.

Screen Cylinders from vee shaped wire for filtration. A V shaped
wire is spirally wound and welded on a cage of longitudinal wedge
shaped or trapezoidal shaped rods. Each and every intersection
between vee shaped wire and the wedge wire is welded automatically.
This creates a continuous spiral slot. These screen tubes cylinders
are also known as continuous vee slot tubes.
Different types of construction are available such as
Rod base construction : Outside to Inside Flow
Wire Base Construction : Inside to Outside flow
Inverted Wire Base : Inside to Outside flow
External Axial Wire : Outside to Inside Flow
Internal Axial Wire : Inside to Outside Flow
External Circumferential Wire : Outside to Inside Flow
Internal Circumferential Wire : Inside to Outside Flow
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.
