  • Patent number: 10707658
    Abstract: A saddle for supporting elongated bodies has a body with a quadrangular section, on the opposite sides of which wedge-inserted coupling members are provided, to couple the saddle with another saddle, so as to have the reciprocal stacking of these saddles on a support. A saddle according to the invention offers the advantage over known saddles of being stacked on previously installed saddles due to the presence of incorporated members which allow their connection, without resorting to the use of tools or similar auxiliary equipment.

  • Patent number: 8561647
    Abstract: A pressure-relieving safety assembly, comprising a sleeve and collar, protects against human injury and loss of life by blocking flow of fluid from a ruptured high pressure conduit and provides pressure relief for escaping fluid. This pressure-relieving assembly includes a sleeve that encircles the high-pressure line and is secured to, at one or both ends of the line, a coupling. The sleeve is secured to the coupling(s) by a collar having raised portions that provides a path for fluid that has escaped from the conduit at a burst or pin-hole failure location, to flow towards the ends of the conduit, indicating to the user that a conduit failure has occurred. The sleeve lowers the fluid velocity while the path provided by the collar prevents the fluid pressure from building up behind the sleeve.

An electrical cable having insulated electrical conductors embedded within an elastomeric jacket extends longitudinally through the interior passage of the tubing. Body members are placed around the outer periphery of the electrical cable, and the body members are compressed onto the electrical cable through the use of an anchor assembly. The anchor assembly is held in a compressed state through the use of frangible support elements. Once the electrical cable is in place within the coiled tubing, the user applies an external force to cause the support elements to fail, thereby releasing the anchor assembly from its compressed state. The anchor assembly contacts the inner wall of the coiled tubing, such that the weight of the electrical cable is transferred to coiled tubing.

  • Patent number: 7905295
    Abstract: Submersible pump power cable is inserted into a length of tubing. The device comprises an anchoring system attachable to the cable affixed to the tubing inner surface. The anchoring system includes an anchoring sleeve slideable over the cable and insertable into the tubing. Coiling the tubing with the cable and anchoring system inside energizes the sleeve into an anchoring configuration to anchor the cable within the tubing. The anchoring system continues to anchor the cable after uncoiling the tubing and inserting it into a wellbore.

    Abstract: An insulated and refrigerated beverage transport line provides enhanced temperature control of one or more beverages conveyed through the transport line. A plurality of coolant lines carrying a re-circulated coolant makes contact with the one or more product lines. One or more empty lines, referred to as packers, may be placed between the coolant lines and the product lines to provide a dimensionally stable and tight group of lines that are bundled together. An external insulation is provided over the bundle of lines to further enhance insulation for the beverage being transported through the product lines. At least one dedicated coolant return line may be placed remote from the other lines. The dedicated coolant return line carries the highest temperature coolant found in a beverage transport system. Independent and separate insulation of this dedicated coolant return line prevents inadvertent heat transfer to the one or more product lines.

  • Patent number: 7854240
    Abstract: The foam tube for pipe insulations has an external surface and an internal surface. The internal surface is provided with an adhesively bonded layer of fibers. The fibers are a material having a melt temperature that is higher than that of the polymeric foam. The fibers are adhesively bonded to the internal surface such as to stand up from the internal surface. The fibers are substantially uniformly distributed over the internal surface providing a surface coverage of 2 to 20 percent. Further, the fibers have a linear density of 0.5 to 25 dtex and a length of 0.2 to 5 mm. With this fiber layer the polymeric foam tube has an improved thermal resistance and thermal conductivity.

  • Patent number: 7849928
    Abstract: ESP power cable is inserted into a length of tubing disposed in a wellbore. The device comprises a support attachable to the cable that is in frictional sliding contact with the tubing inner surface. The frictional sliding contact between the support and the tubing reduces axial stress in the cable. Support devices are added at intervals on the cable length, thereby distributing the cable axial stress along the cable.

  • Patent number: 7829819
    Abstract: A method for securing a component to a tank includes forming the tank having a wall of multiple layers of polymer material with an opening in the wall, outer layers of polymer, and an inner layer of polymer having an inner surface whose color is dark relative to a natural color of the outer layers. The component is formed with a mounting surface of polymer. The tube wall opening is used to install the component in the tank such that the mounting surface contacts the inner surface. Energy is transmitted onto an area of a surface of the tank wall where the mounting surface contacts the inner surface. The transmitted energy is use to produce a weld between the mounting surface and the tank wall.
