摘要： 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 possible. 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.

摘要： 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.

摘要： An underdrain assembly for filtering particulates from a fluid having an upper structure connected to a bottom plate. At least one flow control vane is positioned between the upper structure and the bottom plate for directing and managing fluid flow through the assembly. The upper structure can have first and second filtration members, the second filtration member positioned between the first filtration member and the bottom plate. The second filtration member can have a shape that restricts fluid flow within the underdrain. The underdrain can have air and water inlets. The water inlet can have an end with a plate covering an upper portion thereof. The end can also include an opening having an angular cut forming an angle with respect to a longitudinal axis of the water inlet. Thus arranged, air is prevented from migrating out the water line. A resilient mounting arrangement for the underdrain is also disclosed.

摘要： A screen intake system has a body with an open end and a chamber. A flat screen is disposed at the open end of the body. To keep the screen clear of debris, an airburst system has pipes disposed in the chamber. The pipes dispose parallel to one another adjacent the flat screen, and each of the pipes has orifices in a side facing the flat screen. Directors are disposed along the backs of the pipes in a lattice, and each of the directors has a channel in which the pipe disposes. Compressed air released by valves from a tank dispersed from the pipe's orifices. Each of the directors directs the resulting water/airburst from the orifices toward the adjacent flat screen to clear it of debris.

摘要： A screen assembly including at least upper and lower portions each with screen elements having different orientations. The upper portion includes a first plurality of screen elements and the lower portion includes a second plurality of screen elements. The upper and lower portions are coupled together to form a truncated conical arrangement. At least one screen element of the first plurality of screen elements has a different angular orientation relative to a plane that is perpendicular to the central longitudinal axis than at least one screen element of the second plurality of screen elements has relative to the plane. In some such embodiments, the screen elements of the second plurality of screen elements are each oriented to be in a respective plane that is substantially perpendicular to the central longitudinal axis. The screen assembly may be configured to separate a liquid component and a solid component from a slurry.

摘要： An intake screen assembly including an intake member, a screen support member, and a screen member coupled to the screen support member. The screen member may be formed from a material, such as copper-nickel, that is different from a material, such as stainless steel, used to form the intake member and/or the screen support member. The intake screen assembly may include corrosion protection members for preventing contact between the components of the screen assembly that are formed from dissimilar materials. The assembly may be formed by coupling the screen support member to the intake member, and coupling the screen member to the screen support member.

摘要： An adjustable nozzle assembly for a sieve box and a sieve box including same, including a support assembly and nozzles. A pair of elongated support members may be received through openings in support collars. Nozzles may be operatively connected to the collars. The support assembly, which may include collars and rods, are configured to provide at least one of lateral movement and rotational movement of the nozzles. At least one of the first elongated support member and the second elongated support member may be configured to move when coupled to the sieve box to adjust a spray angle of the nozzles. Pivoting of the one rod about the other rod adjusts the angle at which the nozzles are disposed. The rods may be externally threaded, and the collars may be internally threaded, such that when the rods are rotated, the collars translate laterally along the rods to move the nozzles.
