Smart clamp device for connecting tubing

Номер: US20120126534A1
Автор: Daniel B. Gentle, John E. Morton
Принадлежит: HITCO Inc

A hinged clamp provides quick connection and disconnection of sections of fluid tubing. Some embodiments include a spring-loaded catch mechanism that enables the clamp to be loosely latched, and a winding mechanism that can retract the catch to a securely latched condition. Other embodiments provide a hinged shaft that pivots about an end of the upper clamp ring. A middle section of the shaft can be inserted into a slotted opening in the lower clamp ring, and the winding mechanism can move an engagement surface against the lower clamp ring to securely latch the clamp. An adjustment mechanism is included in these embodiments which can adjust the amount of winding required to engage the clamp. In various embodiments, less than one turn or less than one-half turn is required to engage/disengage the clamp. The clamp can be openable only just enough for insertion of flanged ends of the tubing sections.

Pivoting Pipe Coupling Having a Movable Gripping Body

Номер: US20120256415A1
Автор: Douglas R. Dole
Принадлежит: Victaulic Co

A coupling for securing pipe elements together in end-to-end relation has segments joined at one end by a pivot attachment and at an opposite end by an adjustable connection member. The segments surround a central space which receives the pipe elements. A gripping body is captured between the segments. The segments have angularly oriented reaction surfaces. The gripping body has angularly oriented contact surfaces which interface with the reaction surfaces. When the segments are drawn toward each other by the connection members, interaction between the reaction surfaces and the contact surfaces forces the gripping body radially inwardly. Inwardly facing arcuate surfaces on the segments and the gripping body engage and retain the pipe elements. A method of inserting pipe elements into the coupling while the segments and the gripping body are supported on a seal is also disclosed.

The invention relates to an improved O-ring seal for use as a high vacuum seal. A limitation of standard O-rig seals is the permeation of water through the O-ring. Especially for instruments in which parts are kept at a cryogenic temperature, such as a cryogenic electron microscope, the presence of water in the vacuum is a problem, as this results in ice growth on the cryogenic parts. As a solution often a double O-ring seal is used, or a metal seal. Both of these solutions have severe draw-backs. 1. A method of providing a seal to maintain a vacuum between a first part and a second part , comprising:positioning an O-ring between the first part and the second part, the O-ring having a vacuum facing side and a non-vacuum facing side; andexposing the non-vacuum facing side of the O-ring to dry gas, the dry gas reducing the amount of moisture permeating through the O-ring from the non-vacuum-facing side to the vacuum facing side.2. The method of in which positioning an O-ring between the first part and the second part comprises positioning an O-ring comprising a polymer.3. The method of in which exposing the non-vacuum facing side of the O-ring to dry gas includes exposing the non-vacuum facing side of the O-ring to gas having a water content of less than 0.1 g/m3.4.

Devices, systems, and methods are directed to automated techniques for fitting flanges to tubular sections used to form tubular structures, such as large-scale structures used in industrial applications (e.g., wind towers and pipelines). As compared to manual techniques for fitting flanges to tubular sections, the devices, systems, and methods of the present disclosure facilitate faster attachment of flanges, which may be useful for achieving cost-effective throughput. By way of further comparison to manual techniques, the devices, systems, and methods of the present disclosure may, further or instead, facilitate achieving tighter dimensional tolerances. In turn, such tighter dimensional tolerances may be useful for forming thinner-walled, lighter, and lower cost tubular structures. Still further or in the alternative, automated techniques for fitting flanges to tubular sections may facilitate attachment of multipiece flanges or other non-traditional flange geometries. 1. A system comprising:a plurality of tube rollers upon which a tubular section is supportable as the tubular section rotates in a rotation direction;a fitting unit including a locating roller and a pusher roller spaced relative to one another to define therebetween a pinch through which a flange is rotatable in the rotation direction;a sensing unit including one or more sensors positioned relative to the pinch to detect a radial offset of the flange and the tubular section moving in the rotation direction; anda controller in communication with the sensing unit and the fitting unit, the controller configured to receive one or more signals indicative of the radial offset, to compare the one or more signals indicative of the radial offset to a target value, and, based at least in part on the comparison, to move the locating roller to adjust the radial offset between the flange and the tubular section moving in the rotation direction.2.

Sealing apparatus for applying corrosion prevention compound in the gap between flanges without using heat consists of 3 units including hydraulic power unit, compound injection cylinder unit, and flange belt unit. The present invention is used to apply corrosion prevention compound in the gap between flanges without using heat for melting the compound before sealing. The compound injection cylinder unit comprises two integrally formed cylinders sharing one connecting rod wherein the lower cylinder defines the hydraulic cylinder and the upper cylinder defines the compound injection cylinder. The compound injection cylinder unit is vertically formed on a pushcart provided with wheels for manual transportation. A threaded coupler is provided on top of the lid of the compound injection cylinder for connection with a hose for transferring the compound to the inlet on the flange belt unit. The flange belt unit is provided in various diameters from 2-24 inches. The application of corrosion prevention compound in the gap between flanges is carried out by applying the pressure from the hydraulic cylinder powered by the hydraulic power unit to inject the compound in the cylinder through the hose into the gap between the flanges of pipes.
