  • Patent number: 11543059
    Abstract: A clamping system for connecting a first and a second tube whose opposite ends have clamping surfaces protruding from the cylindrical outer surface of the tubes. The system includes a collar having a belt able to be clamped around the clamping surfaces. The belt includes a first and a second flank between which an internal recess able to receive the clamping surfaces is delimited. The collar carries an external retaining device having a retaining bar, which protrudes axially from the first flank while being oriented transversely to the axis of the collar and which has a transverse retaining ridge, the bar being able, from a rest situation in which the retaining ridge projects towards the axis of the collar relative to the edge of the first flank in the unclamped situation of the collar, to be elastically deformed to space the retaining ridge away from the axis of the collar.

    Abstract: System is a pipe joint restraint for restraining two coupled pipe ends or a pipe end and at least one fitting. The system is used in conjunction with a hubless coupling designed for drainage and sewer pipes of no pressure or low pressure. At least two adjustable circumferential bands with an abrasive grit material adhesively attached to the interior contact portion of the bands are situated one on each side of the hubless coupling; and are fixedly joined by a plurality of spread restrictor braces. The spread restrictor braces contain 45-degree upward bends to create a space between the adjustable circumferential bands and the pipe for the coupling, which serve to prevent separation of the pipe connection under pressure conditions. The pipe joint restraint assembly may be tightened by a fastener assembly containing fully threaded bolts, a barrel nut, and a trunnion.

    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.

The segments surround a central space which receives the pipe elements. One or more gripping bodies are captured between the segments. The gripping bodies are arranged opposite to each other. When the segments are drawn toward each other by the connection members, interaction between the reaction surfaces and the contact surfaces forces the gripping bodies radially inwardly. Inwardly facing arcuate surfaces on the segments and the gripping bodies engage and retain the pipe elements.

    Abstract: A metal clamp with a plastic sleeve, includes a clamp body made of metal, wherein the plastic sleeve is disposed at the clamp body to locate the clamp body. The plastic sleeve can be classified into an integral plastic sleeve and a split type plastic sleeve. The clamp body is fixed to the plastic sleeve by a circumferential groove on the plastic sleeve. The present invention has the advantage as follows. A shaking of the metal clamp in construction is avoided, the plastic pipe and the pipe fitting is able to achieve firm connection. In addition, fittings between the inner diameter on both ends of the plastic sleeve and the plastic pipe is capable of keeping a relative position among the metal clamp, the plastic pipe and the pipe fitting.

  • Patent number: 8464986
    Abstract: A clamp for a tubular hose or cable is disclosed. The clamp comprises a first clamp half, a second clamp half, and a hinge pin. The first clamp half has a first end and a second end and defines a first concave semi-cylindrical face. The first end of the first clamp half carries means for mounting the clamp. The second clamp half has a first end and a second end and defines a second concave semi-cylindrical face. The first clamp half and the second clamp half come together along a parting line and are retained together by a hinge pin. The clamp halves are provided with snap-in liners for easy use. Alternative mounts for mounting the clamp on subsea wire line or tubulars is also disclosed.

  • Patent number: 8448993
    Abstract: A pipe coupling for connecting pipes of the same or different diameters. The coupling has a barrel sleeve with clamping rings on each end. The clamping rings each carry nested seals. An inner portion of each nested seal may be removed so as to adapt the clamping ring to different pipe diameters. Each clamping ring is hinged, but becomes iron-bound upon tightening, so that each ring eventually bends as a unitary ring member.

  • Patent number: 8439408
    Abstract: A pipe repair clamp includes a flexible strap having ends that are brought together when the clamp is closed. A thrust plate is secured near the first end of the flexible strap. A lug is secured to the thrust plate. A lug plate is secured near the second end of the strap. A threaded stud is secured to the lug plate and is used to tighten the clamp. A lug cover plate is secured to the lug and the thrust plate and receives the threaded stud. The lug cover plate includes a curved end portion covering at least a portion of the lug. A locking plate receives the threaded stud. The locking plate slides along a top surface of the lug and over the lug cover plate when the first and second ends of the strap are pulled toward each other when the clamp is tightened around a pipe.

  • Patent number: 8430432
    Abstract: A pipe coupling with an anchoring arrangement for locking the pipes together axially. The anchoring arrangement comprises a tubular casing, a frusto-conical gripping ring with inwardly projecting gripping teeth and tensioning bolts for tightening the casing about the frusto-conical gripping ring. The frusto-conical gripping ring is formed of a plurality of arcuate segments which overlap to form a complete ring. By forming the gripping ring of segments, the gripping ring is able to adapt to pipes that are not truly circular in cross section and a better grip on the pipe may be achieved than with a single-piece gripping ring.

  • Publication number: 20130032110
    Abstract: A sealing collar is provided on a body in which the body has a cylindrical wall on which a hole emerges and a fluid situated in the body is able to escape through the hole. The sealing collar includes a fixing band entirely surrounding the cylindrical wall. The fixing band has a sealing portion to sealedly obturate the hole and a means for closing and tightening the fixing band. The fixing band is provided with at least one claw extending in the direction of the cylindrical wall so that on closing and tightening of the fixing band around the cylindrical wall, the hole is sealedly obturated and the claw is pressed against the cylindrical wall and contributes to immobilizing the sealing collar on the body.
