  • Patent number: 8925969
    Abstract: A spray shield for the pipe connection flange of pipes carrying hazardous fluids. A band composed of metal or other suitable material encompasses a pipe flange and supports a spray diffusion mesh or device so that any spray of pressurized leaked fluid is coalesced to drops or streams of leaked fluid which descend by gravity for collection rather than being sprayed into the environment in the vicinity of the leaking flange joint. The spray shield band is secured about the flange by an over-center latch mechanism that tightens the band and spray diffusion mesh around the flange connection. A locking pin or lockout device is inserted through aligned holes of the latch mechanism when closed and functions to secure the latch against release and movement from its latched position.

    Abstract: A pipe clamp that includes a band, tightening mechanism for the band, a split sleeve within the band, and gasket located inside a circumferential channel in the split sleeve. The split sleeve includes a tongue-and-groove joint in which the tongue has at least one side edge that confronts and engages a side edge of the groove during penetration of the tongue into the groove in response to tightening of the outer band using the fastening mechanism. This provides a metal-to-metal seal at the tongue-and-groove joint. The relative construction of the tongue and groove is such that during penetration of the tongue into the groove, there are areas of spaced separation between the confronting side edges of the tongue and groove. Also, during tightening, the gasket is forced into these areas of spaced separation which provides a second, gasketed seal at the tongue-and-groove joint.

An annular groove is formed at the end 36 of the layer 14 abutting the end part of the hose 10. An elastic impermeable material is placed in the groove which is compressed by the pipe upon insertion. The companion pipe 18 has a protuberance 22 which rests at a position between the end 36 of resin layer 14 and the clamping member so that a seal is formed by elastic compression of the outer surface of companion pipe 18 against the end part of the hose.

  • Patent number: 7093862
    Abstract: A ring member and ring members made of metal are tightened and installed to the outer circumferential surface of a body made of a resin material. Accordingly, the body is prevented from outward deformation. When a tube joint is used in a high temperature atmosphere, even if any force acts on a fluid tube in the direction to cause detachment from the tube joint due to any external force or the pressure fluid flowing through the inside of the tube joint, then the fluid tube and a connecting member inserted into the body are reliably prevented from disengagement.

  • Patent number: 7090255
    Abstract: A clamp locator for hose assemblies is provided. The clamp locator includes releasable connections for holding hose clamps during assembly of a hose to a hose fitting. The releasable connections comprise generally elastic fingers that hold the clamps to the locator. As the hose clamps are crimped and closed over the hose the clamps are pulled from the fingers and released from the locator. The locator includes a reference locating tab protruding from the body of the locator. The tab corresponds to a reference locating groove in a fitting to which the hose is to be attached. The locator, with clamps attached, is first slid over an end of the hose and the fitting is inserted into the hose end. A ramp on the fitting leads the tab to the groove in the fitting as the fitting is inserted into the hose end. The tab will snap into the groove, indicating that the hose, fitting and clamps are properly aligned. The clamps are then crimped over the hose and the locator released for proper disposal.

  • Patent number: 6899360
    Abstract: A hose and clamp assembly comprises a hose, a band-type clamp encircling the hose, and an elastomeric envelope bonded to the hose and attaching the clamp to the hose along a section of the clamp band. The elastomeric envelope is provided with at least one discontinuity to define a removable center section whereby the removable center section can be separated along the at least one discontinuity to form an open channel in the envelope and enable removal of the clamp. The at least one discontinuity can comprise a groove or a plurality of perforations. The at least one discontinuity can comprise parallel grooves aligned with the edges of the clamp band to define the removable center section. A channel is formed in the envelope by the removal of the removable center section and the clamp to provide a receptacle for proper positioning of the replacement clamp on the hose.

  • Patent number: 6874822
    Abstract: A resinous tube has opposite ends into one of which a mating member is fitted and with which the mating member is connected, and includes a sealing ring, a fastening cap, and a clamp. The sealing ring is disposed on an inner peripheral surface of the opposite end, and contacts elastically with an outer peripheral surface of the mating member. The fastening cap is disposed on the inner peripheral surface of the opposite end on an outer end side thereof with respect to the sealing ring, and contacts elastically with the outer peripheral surface of the mating member. The clamp is disposed on an outer peripheral surface of the opposite end, which is provided with the fastening cap on the inner peripheral surface, and tightens the fastening cap. The resinous tube exhibits good sealing and fastening abilities, requires less component parts, and can be connected with any mating members.

  • Patent number: 6824169
    Abstract: A clamp subassembly includes an annular clamp and a clip attached to the clamp. A hose and clamp assembly includes a hose having an outer surface and an opposing sealing surface and includes the clamp subassembly. The clamp surrounds the hose and has an inner surface with an adjustable diameter. The clip includes a tang having a free end embedded in the hose providing attachment of the clamp subassembly to the hose, wherein no portion of the clamp and no portion of the clip interferes with the sealing surface of the hose. A method for attaching an annular clamp to a hose includes attaching a clip to the clamp, wherein the clip includes a tang having a free end. The clamp is disposed to surround the hose. The free end of the tang is embedded in the hose. In a different embodiment, for the assembly and the subassembly, the clamp and the tang together define a monolithic structure.
