Hengyuan designs and builds water well screens in a vast array of sizes, shapes and materials. Hengyuan's wedge wire screens are generally made from stainless steel, galvanized steel. Slots as narrow as 0.1mm and up to a maximum of 15mm allow precise matching of the screen opening size to the materials to be filtered. These well screens are typically used in water wells, oil wells and geothermal wells. The maximum screen length can reach up to 6 m.

Bottom Line for the Water Well Screens
1. A well screen is a piece of pipe with slots around its length. Rigid construction, a maximum open area up to 60% and precise slot openings suit the wedge wire screen for use in fine and silty sand aquifers.
2. A wedge wire design reduces the risk of clogging and is easy to backwash.
3. Large screen areas increase the chance of clean water entering the well while still keeping impurities out. This means more water can easily enter the well, keeping pumping costs low. The water also undergoes less of a pressure drop, which reduces the energy consumption through the pumping process.
4. Water enters at a low speed, under a low pressure, which reduces erosion on the screen surface and improves the screen's service life.
5. For the given length, diameter and slot opening size, Hengyuan's filter screens allow for a flow rate that is 3 times higher than the bridge slot screen, and 9 times that of a louvered well screen.
6. Customers can choose the slot opening size anywhere between 0.1 to 6mm, based on specific application requirements.

Applications for the Water Well Screen
Hengyuan's wedge wire screen works well with deep well and submersible pumps. It is also commonly used in vertical wells, deviated wells, and directional wells.
