Patent number: 11619331Abstract: Gasket seals for high pressure applications include retaining elements with inner diameter seal elements that interlock with the retaining element to provide resistance to movement in both axial and radial directions between the retaining element and seal element. High pressure sealing may be accomplished using a metallic core retaining element to which an electrically isolating material is bonded on either or both sides. Sealing is achieved through an inner diameter dielectric sealing element, such as a polytetrafluoroethylene (PTFE) inner diameter sealing ring. Flanges of a joint in a fluid flow ling may be bolted together with the gasket seal interposed therebetween. In the event of pressure changes, the inner diameter seal resists being drawn into the flow line, and resists axial movement relative to the retaining element, through dual locking members that secure the seal to the retaining element.Type: GrantFiled: January 28, 2021Date of Patent: April 4, 2023Assignee: Garlock Pipeline Technologies, Inc.Inventors: Ian Brown, Ryan M. Buttimer, T. Scott Tanner, Christopher Remley

Patent number: 10184603Abstract: A pipe end fitting assembly that includes an outer body having an outer surface, an inner surface defining a first bore, and an end surface, and an inner body having an inner surface defining a second bore and an outer surface. A portion of the inner body outer surface is secured to the outer body inner surface. A passage formed in the outer body includes a first portion extending from the end surface and parallel to the first bore, and a second portion extending from the outer body outer surface to the passage first portion. A pipe end is disposed around and secured to a portion of the inner body outer surface. A jacket is disposed around the pipe and has an end secured to the outer body outer surface. The passage portions are in fluid communication with each other and a space between the jacket and the pipe.Type: GrantFiled: October 4, 2012Date of Patent: January 22, 2019Assignee: FLEXSTEEL PIPELINE TECHNOLOGIES, INC.Inventors: Matthew Allen Hegler, Andrew James Heaton

Patent number: 8985496Abstract: A drum assembly having a post, and first and second spoke frames. Each of the first and second spoke frames includes expandable spokes and immovable spokes, extending away from the post. Each expandable spoke includes a distal end movable between a retracted position and an extended position. A plurality of first drum segments each are mounted to the distal end of one of the expandable spokes of the first spoke frame and to the distal end of one of the expandable spokes of the second spoke frame. A plurality of second drum segments each mounted to an end of one of the immovable spokes of the first spoke frame and to an end of one of the immovable spokes of the second spoke frame. Mechanical actuators, extending between the post and either the expandable spokes or the first drum segments, move the expandable spokes between the retracted and extended positions.Type: GrantFiled: January 9, 2013Date of Patent: March 24, 2015Assignee: FlexSteel Pipeline Technologies, Inc.Inventors: Brian Dillinger, Jagtar Thethy

Publication number: 20150059810Abstract: An improved apparatus, system, and method for removing debris from lightweight components are disclosed. The improved apparatus can include an air mover, a cyclonic chamber in fluid communication with the air mover, an enclosure component operably attached with the cyclonic chamber, and a debris collection component in fluid communication with the cyclonic chamber. The lightweight components positioned inside the cyclonic chamber can be moved, rotated, or carried by cyclonic airflow, causing the lightweight components to hit against one another or against the sidewall, so as to separate the debris clung thereto.Type: ApplicationFiled: September 4, 2013Publication date: March 5, 2015Applicant: GARLOCK PIPELINE TECHNOLOGIES, INC.Inventor: Ian W.

Patent number: 8678398Abstract: Sealing systems for high pressure applications that provide electrical isolation between joined elements as well as enhanced resistance to leakage of media during a fire. High pressure sealing is accomplished using a metallic core to which an electrically isolating material is bonded on either or both sides. Sealing is achieved through a dielectric sealing element, such as a spring-loaded polytetrafluoroethylene (PTFE) ring. Flanges of the joint may be bolted together with the seal interposed therebetween, and the flanges bolted together. In the event of a fire, heat may be generated that is at a high enough temperature to burn away the isolating material and PTFE ring. Systems of various embodiments provide a metal core backup seal and a compression limiter, which, respectively, prevent the media from leaking from the joint and maintain bolt load at the flanges.Type: GrantFiled: July 11, 2011Date of Patent: March 25, 2014Assignee: Garlock Pipeline Technologies, Inc.Inventors: Thornton J. Anderson, Ben D. Kramer, Sigfrid Ruz, T. Scott Tanner

Patent number: 6170533Abstract: A pipe has a wiremesh reinforcement-plastic composite construction that includes a first and second spiral reinforcing wire layer. The first spiral reinforcing layer has grooves formed at selected intervals, and the second spiral reinforcing wire layer is pressed into the grooves. The first and second spiral reinforcing wire layers are deformed and joined together by pressure to form a wiremesh reinforcement. The two spiral reinforcing wire layers have a left and right spiral angle &agr;1 and &agr;2 respectively relative to the central line, the left and right spiral angles &agr;1 and &agr;2 can change in the range of 0° to 90°. Thermoplastic penetrates the wiremesh reinforcement and fills both sides of the wiremesh reinforcement to form the composite pipe or component.Type: GrantFiled: June 15, 1998Date of Patent: January 9, 2001Assignee: Starway Pipelines Technology Inc.Inventor: Yi Liang He

Patent number: 5987990Abstract: A flaw detection system for a prestressed concrete cylinder pipe uses hydrophones inserted into valves in the pipe while the pipe is in use. The hydrophones listen for sounds that are consistent with the breaking of the pre-tensioned reinforcements and the sliding and re-anchoring of broken ends. Detecting the sound at two or more locations and establishing precise time differentiation allows the precise calculation of the location of the defect. Global positioning system (GPS) satellite receivers provide precise timing of reception of the targeted sound events in milliseconds. The location of each of the hydrophones is established using GPS. Each hydrophone is connected to a box, which includes a pre-amplifier, a signal processor, a memory, an output and a GPS receiver. The hydrophone, or box, or both, are tunes to recognize a significant sound that emanates from a breaking, moving or re-anchoring reinforcement. The precise time of arrival of that sound is recorded in the boxes using the GPS time signals.Type: GrantFiled: November 4, 1997Date of Patent: November 23, 1999Assignee: Pipeline Technologies, Inc.Inventors: Henry W.
