  • Publication number: 20150008669
    Abstract: A pipe joint is connected with a connecting pipe, and includes a pipe joint body and a nut member. When the connecting pipe formed with a bead expanded in the radial direction is connected with this pipe joint, a male thread of the pipe joint body is engaged with a female thread of the nut member to hold the bead between a tapered face and a tapered face. In addition, the joined portion between the bead and the tapered face forms a first sealed portion, and a joined portion between the bead and the tapered face forms a second sealed portion. Still further, a tapered face of the pipe joint body is joined with the tapered face of the nut member to form a third sealed portion.

  • Publication number: 20140110936
    Abstract: Provided are a fixing device for a lower-stage member which facilitates a leveling operation for making upper surfaces of lower-stage members coplanar, and can further enhance a vibration absorbing effect generated by an elastic member, and a fluid control device which includes the fixing device. A fixing device for a lower-stage member is configured such that respective lower-stage members are fixed once and, thereafter, a desired lower-stage member is moved upwardly against an elastic force so as to finely adjust positions of upper surfaces of a plurality of lower-stage members. The elastic member is formed of an annular body made of rubber or a synthetic resin. A cutout which imparts the elastic deformation by bending when a force in the vertical direction is applied to the elastic member is formed on an upper portion and a lower portion of an inner peripheral surface of the elastic member.

  • Patent number: 6695357
    Abstract: A connection for threaded pipes and other tubular sections including a gasket for interposition between a first and an opposing second interface surface of the connection. The gasket includes a retainer and a generally annular seal element received in a groove formed into at least one side of the retainer. Such retainer side further is formed as having one or more channels extending extend radially through the groove and the inner or outer perimeter of the retainer. Each such channel defines a vent for relieving hydrostatic fluid pressure as the gasket is compressed between the interface surfaces.

  • Patent number: 6527304
    Abstract: A connector (10) for sealing an elongated tube (14) to a body (22) comprises a nut (12) concentrically about the tube (14) proximate the flared end (16). The nut (12) has a threaded exterior portion (34) and an abutting face (42) proximate to and concentric with the exterior face (32) of the flared end (16). A non-linear spring (44) between the exterior face (32) of the flared end (16) and the abutting face(42) of the nut (12), and is displaced upon tightening of the nut (12) to the body (22) to generate a substantially constant restorative force over a portion of the displacement to urge the interior face (30) of the flared end (16) into sealing engagement with and against the shoulder (38) of the body (22).

  • Patent number: 6481762
    Abstract: A pipe coupling for attachment to a pipe includes a sleeve. One end of the sleeve is configured to receive a pipe end. The pipe coupling also includes an annular gasket disposed within the end of the sleeve for encircling the pipe end. The coupling includes a flanged assembly for compressing the annular gasket to form a seal between the pipe and the sleeve. The sleeve and the gasket are configured so as to define a leak path between an axially inner portion of the gasket and the inner surface of the sleeve, whereby pressurized fluid from the pipe may pass along the leak path so as to pressurize a radially outer surface of the gasket and urge the gasket against the compression flange to enhance the seal between the gasket and the sleeve.

  • Patent number: 6447028
    Abstract: A fitting for connecting two components is described. The fitting may be explosion proof for use in hazardous environments. The fitting may swivel allowing fast and easy connection to fixed components, thus minimizing the time required for installation and periodic maintenance, while maintaining the integrity of the explosion proof fitting. In this way, components—such as electrical conduits containing conductors or wires—can be installed and maintained without the use of damming material. Also described is a method of installing an explosion proof fitting for use in hazardous environments.

  • Patent number: 5842817
    Abstract: A compression or jacking ring includes a first component constructed of two layers of a material that is comparatively non-elastic and has a Poisson's ratio preferably not greater than 0.3. A second component that is comparatively elastic and has a comparatively high Poisson's ratio is sandwiched between sections of the first component. The compression ring is sized and shaped to be positioned between facing surfaces of pipe sections in a string of pipe sections utilized for forming a pipe within a pipe receiving tunnel. In particular, the compression ring is constructed to transfer a load between adjacent pipes during insertion of the pipes into a tunnel so as to spread the load over a comparatively large surface area if the pipe sections become non-axially aligned relative to one another during insertion so as to reduce the likelihood of breakage.

  • Patent number: RE36206
    Abstract: An improved expandable gasket, sealed joint and method of forming a sealed joint which includes a gasket having at least 5% by weight unexpanded or unexfoliated graphite. The graphite material is preferably a mixture of expanded and unexpanded graphite compressed in a sheet or other shape affixed to a metal plate. The preferred composition is 5 to 70% by weight of unexpanded graphite and 30 to 95% expanded graphite, wherein the percentage of unexpanded graphite is controlled to provide the desired gasket expansion. A more preferred composition includes at least 10% by weight unexfoliated graphite or more preferably 15 to 50% by weight. The gasket is placed between the surfaces to be sealed and clamped in place. When the joint is heated, the unexpanded graphite exfoliates, causing the gasket to swell or expand, tightly sealing the joint.
