Abstract

A screen for intake of fluid. The screen includes parallel and spaced rods, filtration material, a fitting, and structural members. The rods may be distributed in a cylindrical configuration. The filtration material, in some embodiments spirally wrapped wire, is disposed around the rods to define an interior volume. The fitting is disposed at an end of the rods and adjacent to the filtration material. Each structural member, which in some embodiments are elongated bars, is interposed between adjacent rods. The structural members are welded to the adjacent rods, and the adjacent rods and the structural members are welded to the fitting to increase the effective weld area, the tensile strength of the connection, and potentially the overall strength of the screen. The screen may be used for a variety of fluids and installations, and is particularly suited to use in water wells.
