Wedge Wire Screen
Wedge Wire Screen Tube is manufactured by wrapping and welding
stainless steel V-shaped profile wire cylindrically around support
rods under automatic specialized wedge wire screen machine. Each
profile wire and support rod is contacted by resistance welding.
This screen tube is with features of firm in structure, good
mechanical properties, high strength, rigidity and load capacity.
For the section of profile wire is V shaped, the screen slot is
narrow in the above and wide in the below, and thus be easy to
leakage,wear and corrosion resistance, avoiding clogging and ensure
smooth filtration. It is widely used in oil-water separation, water
treatment, sugar process, rotating pulping.
Materials: carbon steel and stainless steel (302, 304, 304L, 316, 316L, etc).
Characteristics: The welded stainless steel water well 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). Water well
screens have a structure and high open area, as well as accurate
slot dimension. At the same time, water well screen have
heat-resisting, anti-corrosive, good machine capability, last long,
safety and reliability and so on characteristics. It can be used in
many kinds of medium filtering.
Features of products:
1) Screens with high open area are more suitable for the
construction of high-quality water wells, oil wells and gas wells.
2) Low cost operation
Screens with high open area shall favor groundwater infiltration.
Abundant water shall reduce the water level’s down, thus to save
3) Reduce the abrasion of the pump
Under the same condition, high open area can make the speed of
groundwater’s entering into the screen much slower than any other
filtration apparatus, which will avoid sand’s entering into screen
because of high pressure, thus reduce the abrasion of the pump.
4) Extend the life span of wells
Comparatively, groundwater’s entering into screen with higher open
area is much easier than the entering into lower open area screen.
The slow water flow shall extend the life span of wells.
A continuous slot opening which significantly increases the
available open area, thus providing greater access to the water
A “V”shaped profile wire which avoids clogging and ensures an
A uniform and efficient well development due to the continuous slot
Ladder-like wire welded screens have a strong structure and high
open area, as well as accurate slot dimension.
Ladder-like wire welded screens have the features of easy
backwashing, last long, safety and reliability as well as low
Uses: The strainer is a kind of filtered water tubing with the
perforation .it can use with the deep well pump, dive the water
pump, also may use in the water-treating equipment, the
environmental protection, the sea water transforms into the
industrial water and life use water desalination treatment, running
water treatment, water softening treatment, the petroleum industry:
The petroleum product terminal filters and the chemical acid, the
alkali liquid filters, the ethyl alcohol and so on the organic
solution recycling filters.
