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 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.

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 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 pipe for connecting to a similar adjacent pipe. The pipe has a male end with a plurality of rigid fingers extending from within and out of at least one exterior circumferential groove disposed on its exterior surface. On the female end is at least one interior circumferential groove sized and positioned to receive the plurality of rigid fingers from a corresponding exterior circumferential groove on the male end of an adjacent pipe. The number of exterior circumferential grooves on the male end typically corresponds to the number of interior circumferential grooves on the female end. When the male end of the pipe inserts into the female end of a similar adjacent pipe, the plurality of rigid fingers is received within a corresponding interior circumferential groove on the female end, thereby preventing the male end of the pipe from being withdrawn from the female end of the similar adjacent pipe.

摘要： Apparatus and related method for coupling adjacent pipe lengths, for example, a drop pipe assembly that utilize an intermediate coupling member to prevent rotational disengagement of adjacent pipe lengths under the influence of rotational torque. The coupling member can comprise an internal key feature that physically engages a keyed end on at least one end of a length of pipe. The internal key feature can include key members located on each coupling end of the coupling member such that the key members engage corresponding keyed ends of adjacent lengths of pipe such that the coupling member prevents rotation of the adjacent pipe length relative to each other.

摘要： A vacuum sewage system includes a sump pit for receiving sewage, a valve pit, a valve, a sensor-controller, a first sensor pipe, a sump breather and a second sensor pipe. The sensor-controller activates the valve so as to discharge sewage from the sump pit. The first sensor pipe communicates pressure to the sensor-controller as the level of sewage rises within the sump pit. The second sensor pipe communicates pressure to the sump breather to move the sump breather from a first state to a second state to prevent sewage from entering the sensor-controller and valve. Alternatively, the system may be provided with a single sensor pipe that communicates pressure to both the sensor-controller and to the sump breather.

摘要： A support grid assembly for use in a pressure vessel includes one or more screen panel assemblies that are flexibly, fluidly coupled to a central fluid manifold. Each screen panel assembly is operably slidably inserted into a central fluid manifold, whereby a flexible connection fluidly individually seals each screen panel assembly to the central fluid manifold. Through the use of a flexible connection, each screen panel assembly can individually slide, rotate or otherwise shift relative to the central fluid manifold and into engagement with a vessel floor regardless of inconsistencies in the vessel floor.

摘要： Screen intake assemblies and related methods of fabrication and operation that improve both operational performance and structural strength. The screen intake assembly can include one or more screen portions that run substantially and continually along the length of the screen assembly to provide increase fluid intake and uniform flow. The screen intake assembly can comprise a central manifold having an exterior manifold screen portion to provide additional filtering capacity. The screen intake assembly can be used alone or in combination with internal flow modifier structures to increase fluid intake and uniformity. Internal flow modifiers can include a perforated flow modifier pipe, an internal flow modifier pipe, and/or converging flow modifiers. The screen intake assembly can include cleaning systems that operate continuously or on demand.

摘要： A utility conduit and related methods of assembling lengths of utility conduit with a mechanical spline connector. The utility conduit includes opposed male and female ends, wherein the male end is slidably insertable into the female end of adjacent conduits. The female end includes one or more circumferential sealing channels into which a seal member is positionable and an internal spline groove that is circumferentially defined inside the conduit. The female end includes a wall bore through a conduit wall that intersects with the internal spline groove. The male end includes an exterior spline groove on an exterior of the conduit. A spline can be inserted through the wall bore and into a space cooperatively defined by the internal spline groove and the external spline groove. The spline is inserted such that the spline occupies the space cooperatively defined by the internal spline groove and the external spline groove.
