The continuous-slot water well screen pipe 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 water well screen is made by winding cold-rolled wire, approximately triangular 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.
