Water Well V Wedge Johnson Wire Screen Filter Strainers / Sand Filtration Media

Water well drilling is a rugged business. The stresses of installation along with the pressures and corrosion that are encountered downhole require a tough screen. At Delta Screens we manufacture our wedge wire stainless steel screens with some of the industry's most experienced screen craftsmen and the most advanced screen-building technology in the world. You can have the utmost confidence that our stainless steel screens will stand the test of time with your water well application, whether it's a small domestic well or a large municipal installation.

Our stainless steel telescope screens and pipe size screens are available in 304 or 316 grade stainless steel in a wide range of diameters.

Hengyuan offers water well screens made from Stainless Steel SS 304. The screens are manufactured by wrapping a wire around longitudinal rods. The wire is welded to the rods by resistance welding producing a cage-shaped cylindrical configuration.

There are several advantages a water well screen offers:

• The water well screen is a key component for controlling the sand entering the water bore circuit. The slot design of the screen resists plugging and prevents sand from damaging the pumps. The slots in the water well screens are unique in shape. The inwardly widening shape from the very edge of the slot allows only two point contact with any grain outside it. If the grain size is even marginally smaller, it slips right through without facing any resistance and is then removed out of the well with the water. The larger grains however remain outside. This design feature makes these screens non clogging type.
• While the slotted UPVC pipes have least open area 10%-15%, the 'V' wire wound screen has highest possible open area (14%-50%). The high open area allows for water to enter the well freely resulting in minimal drawdown and less energy usage by pump.
• The wire and rod construction offers required strength for specified well depth.
• The unique water well screen design allows for lower entrance velocity of the water, reducing the encrustation rate.
• As the screen is made from stainless steel it offers maximum corrosion resistance for water chemistry.
• The right selection of slot size is made after below ground sand sample analysis. The slot size, diameter, and the length of the screen can be customized to suit the requirement of the well.
