Publication number: 20120043752Abstract: The invention is a pipe joint for joining pipes composed of materials that are difficult to adhere. The major elements are an extrudable adhesive; a first pipe having a socket with an inside diameter, where said socket has a mouth, a self-centering bottom with a gasket, a cylindrical wall with a plurality of ports, and an inner annular channel. A second pipe has an insertion section with an squared-off end and a rolled groove. The second pipe having an outside diameter that is less than the inside diameter of the socket, where the difference defines a coaxial cavity with a width. The rolled groove serves as a distribution channel while the adhesive is a liquid, and upon curing the solid adhesive functions as a retaining ring. A flanged annular ring, potentially aided by a compression apparatus, caps the cavity, centers the insertion section, and maintains compression. The adhesive includes alkyl-borane-adhesives.Type: ApplicationFiled: October 31, 2011Publication date: February 23, 2012Applicant: IPS, Corporation - Weld-On DivisionInventor: TERRY R. MCPHERSON

Patent number: 8042576Abstract: The present invention provides a test plug for use with a clean-out that extends at an angle from a pipe section of a pipe system. In general, the test plug includes a sealing assembly that is actuated by an actuating member extending at an angle from the sealing assembly. The sealing assembly includes a first plate, a second plate, a valve that is configured to draw the first and second plates together, and a ring-shaped sealing member located between the first and second plates. In various embodiments, the actuating member is configured to move the valve between an open position, in which test media may be communicated through at least one opening in the first plate and through at least one opening in the second plate, and a closed position, in which the valve seals the opening of the first plate and in which the sealing member extends outwardly to seal against an internal surface of the pipe section.Type: GrantFiled: March 26, 2009Date of Patent: October 25, 2011Assignee: IPS CorporationInventors: Stephen Peterson, Richard Larson

Patent number: 7597118Abstract: The present invention provides a pneumatic test plug that seals a portion of a pipe section having a generally cylindrical internal pipe wall. In general, the pneumatic test plug includes an inflation valve mounted in the bladder wall of an inflatable bladder. The inflation valve includes a main air passageway through which air is introduced into the bladder and a separate release channel. The separate release channel includes an inlet disposed toward an interior end of the inflation valve and an outlet in fluid communication with an exterior environment outside the bladder. When in a sealed position, a sealing portion of the bladder engages the interior end of the inflation valve and sealingly closes the inlet of the release channel. When the sealing portion is elastically deflected by overinflation of the bladder, the sealing portion uncovers the inlet of the release channel to allow air to escape from the interior area of the bladder through the release channel to the exterior environment.Type: GrantFiled: March 26, 2009Date of Patent: October 6, 2009Assignee: IPS CorporationInventors: Stephen Peterson, Richard Larson

Publication number: 20090014121Abstract: The invention is a pipe joint that is particularly suitable for joining pipes composed of materials having a low surface energy and excellent resistance to solvents. The major components are an extrudable adhesive; a first pipe having a socket with an inside diameter, where said socket has a mouth, a self-centering bottom, and a substantially cylindrical wall with an inlet, an outlet, and an inner annular channel; a second pipe having an insertion section with an end and an outer annular channel, said second pipe having an outside diameter that is less than the inside diameter of the socket, where the difference in diameters defines a cap and where the outer annular channel lines up with the inner annular channel therein forming an interlocking keyway; and a flanged annular ring, where said annular ring has an inside diameter that enables it to be slid over the second pipe and a thickness that is comparable to the gap, and where the flange has a width that is sufficient to cap the mouth of the socket.Type: ApplicationFiled: March 10, 2008Publication date: January 15, 2009Applicant: IPS, CORPORATION - WELD-ON DIVISIONInventor: Terry R.

Patent number: 7464727Abstract: The present invention addresses provides a clean-out plug that seals a pipe system clean-out that includes a clean-out end and an inner surface, a portion of which is threaded. In general, the clean-out plug includes a compressible sealing member that is retained by the clean-out plug and that seals against an inner surface of the clean-out and/or the back side of the threaded portion of the clean-out. The clean-out plug may also include a cover plate that is secured to the clean-out plug via a second retaining member that engages a first retaining member of the clean-out plug. By sealing against the inner surface and/or back side of the threaded portion of the clean-out, various embodiments of the present invention do not seal within the treaded portion of the clean-out, which is often damaged by cross-threading from previous removals and reinsertions of threaded clean-out plugs.Type: GrantFiled: October 22, 2007Date of Patent: December 16, 2008Assignee: IPS CorporationInventors: Richard E. Larson, Steven S. Peterson
