A pipe coupling for connecting adjacent pipes. The pipe coupling has a connection type at each end that may be male or female. A female end may have an interior surface defining a receiving chamber. An interior circumferential groove is formed in the interior surface in which a band is seated. A plurality of rigid fingers is extends from the band into the receiving chamber. The receiving chamber receives a male end of an adjacent pipe, the male end having an exterior surface. An exterior circumferential groove is defined on the exterior surface to receive the plurality of rigid fingers. A variety of connection types and combinations are disclosed. The female end may define a sight window to permit viewing of the position of a male end of an adjacent pipe. The receiving chamber may have a reduced diameter proximate to the middle of the coupling to improve sealing.

Pipe coupling

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, which can be 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 can be 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.

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.
