Abstract: A filter element is provided with a cartridge locating system. The filter element includes a closed end cap and an open end cap with a tubular ring of filter media disposed between the end caps. The filter element includes an annular seal that can seal to round and non-round sealing surfaces and acts to block fluid flow between the open end cap and a pipe assembly in a pressure vessel assembly. A support bar is enclosed by the filter media and has a key. The filter element has a key receptacle to receive the key of the support bar. The user knows that the seal between the filter element and the pipe assembly is fully aligned and engaged when the key from the support bar fully enters the key receptacle of the filter element.

Abstract: A pipeline contaminant monitoring apparatus that includes a filter housing and probe configured to isokinetically sample a portion of a pipeline gas stream. The filter housing has a filter configured to trap solid contaminants within the gas stream. A first pressure sensor is located upstream of the filter and a second pressure sensor is located downstream of the filter. A processor is coupled to the first and second pressure sensors. The processor is configured to determine a solid contaminant concentration level in the gas stream based on a rate of change of the pressure drop sensed across the filter.

Abstract: Improvements to filtration and vessels such as for filtration and coalescing of gas streams are shown. A filter element with a partial treated region and untreated region such as providing different surface energies or other filtration characteristics are provided. Various keying arrangements for compatibility and /or rotational locking are shown between the filtration vessel, a tubular coalescing baffle, and/or filter element. The tubular coalescing baffle also may include non-louvered pore structure, which provides for more even flow in a two stage type filtration vessel to prevent premature exiting and reduction of flow velocities along the second stage, and/or may additionally or alternatively include drainage apertures such as drain slot formed along a gravitational bottom or otherwise to facilitate additional drainage of coalesced liquid as opposed to letting such liquid be forced through fluid velocity toward the open end of the tubular baffle.

Abstract: There is disclosed a liquid filter system that includes a liquid filter apparatus configured to self-clean without removal of the filter apparatus from the filter system. The filter apparatus uses both a filter media for filtering solids as well as a spin motion imparted to fluid being filtered so that centrifugal force can remove solids from the liquid being filtered. The liquid filter system also includes a gas pulse nozzle in fluid communication with the liquid filter apparatus and is configured to flow gas into the filter media to expel water and debris trapped in the filter media without removing the filter media from the filter system.

Abstract: A removable, reusable, pleated woven wire filter comprising: (a) a stainless steel perforated core having one-half-inch stainless steel round bar reinforcement rings welded to one-half-inch stainless steel round bar cross bars to create bar-ring junctures, and having 11-gauge stainless steel attachment clips welded to each end of the perforated core; (b) a three-layer stainless steel pleated woven wire filter media wrapped around the perforated core, the filter media having spaced apart pleats with external peaks, and an external filter media surface comprising the external peaks of the pleats; (c) a stainless steel flattened expanded metal shroud adjacent to and encircling the external peaks, and (d) a stainless steel top end cap base and a stainless steel bottom end cap base connected to the metal shroud, both cap bases sealed against top and bottom ends of the filter media with a stainless steel adhesive sealant rated at 2,000 degrees Fahrenheit.

Abstract: Multi-stage filtration apparatus is provided. A fluid is forced through different filter stage elements allowing for removal of various contaminants from the fluid.

Abstract: A filter formed essentially from a staple fiber is provided. A nonwoven staple fiber is compressed in to a mat or sheet of selected porosity. The mat or sheet does not include a binder or bicomponent fibers. The staple fibers may be heat treated. The sheet is formed into a selected geometric shape and the staple fibers are thermally fused to bind the staple fibers into a porous filter element. The preferred shape is a helically wound tube or plural sheets, each sheet being self-overlapped and compressed to overlap another sheet. Each sheet is preferably heated and compressed individually and the sheets may be selected to have different porosities and densities.

Abstract: A single support core for a filter media assembly. The single support core includes a single longitudinal tube extending between a first end and a second end. A plurality of orifices are defined in the tube, the orifices align circumferentially along the longitudinal length of the tube. A first plurality of portions defined between the first end and an intermediate annular ring joint and a second plurality of portions defined between the intermediate annular ring joint and the second end. The orifices in each of the first portions and second portions are equidistance circumferentially from each other defining rings. The rings are equidistant longitudinally from each other in each of the portions and the rings are longitudinally spaced differentially in the adjacent portions. The plurality of orifices direct fluid flow through the tube to yield a high flow velocity in predetermined areas along the length of the filter assembly.
