Description

Our company is a professional mnufacturer of well screen.my *: *@********************m







I'm Joanna sun from hengshui China guangxing screen Co.ltd 







A well screen is a filtering device that serves as the intake portion of wells constructed in 







unconsolidated or semi-consolidated aquifers.  The screen permits water to enter the well 







from the saturated aquifer,  prevents sediment from entering the well, and serves 







structurally to support the aquifer material.  The importance of a proper well screen cannot 







be overemphasized when considering the efficiency of a well and the log-term cost to its 







owner. 







Well screens are manufactured from a variety of materials and range from crude handmade contrivances to highly efficient and long-life models made on machines.  The value 







of a screen depends on how effectively it contributes to the success of a well.  Important 







screen criteria and functions include: 







Criteria: 







1. large percentage of open area 







2. non clogging slots 







3. resistant to corrosion 







4. sufficient column and collapse strength 







Functions: 







1. easily developed 







2. minimal incrusting tendency 







3. low head loss through the screen 







4. control sand pumping in all types of aquifers
