Continuous-slot well screen
The continuous-slot screen is widely used throughout the world for water,oil,and gas wells,and is the dominant screen type used in the water well industry. Continuous-slot screen is made by winding cold-rolled wire,approximately trianngular in cross section,around a circular array of the longitudinal rods. The wire is attached to the rods by welding, producing rigid one-piece units having high strength characteristics at minimum weights. Slot opening for continuous screens are manufactured by spacing successive turns of the outer wire to produce the desired slot size. All slots should be clean and free of burns and cuttings. Advanced solid construction suitable for installation to depths of ±400 meters. Completely corrosion free eliminating electrolysis reaction. Screens are provided with threaded female ends and connected by means of a separate nipple (adaptor) retaining length and internal and external smoothness. A maximum open area of 60% is offered facilitating high flow capacity and low inlet resistance resulting in extended well life. The hydraulic advantages afforded by screen 2000 make it also suitable for low yield water bearing strata. Lightweight easy to handle. Competitively priced.
