  • Patent number: 4421136
    Abstract: A drain pipe arrangement for draining water from a floating roof of a storage reservoir includes a flexible drain pipe connected to the roof, and a flexible heating element within the drain pipe. The flexible heating element takes the form of two rigid metal tubes twisted on each other and having their upper ends connected together. A pump and heater provide for circulating heated fluid through the tubes to prevent drain water from freezing in the drain pipe.

  • Patent number: 4377186
    Abstract: A flexible buoyant conduit which includes a thermoplastic pressure-resistant stratum. The pressure resistant stratum is formed by spirally winding, and overlapping, a belt or band the cross-section of which is in the form of an elongated S-shape having a groove in the bottom wall of each channel.

  • Patent number: 4344462
    Abstract: A flexible conduit has an undulating liquid tight inner tube portion and layers of metal reinforcing wound around the tube. The layers include a burst resisting layer adjacent the tube, then traction and pressure resisting layers, and an outer sheath. The undulations in the interior of the tube can be filled with packing or the tube can be lined with a spiral strip to lessen resistance to fluid flow through the conduit.

  • Patent number: 4332509
    Abstract: A piping or conduit system in which conduits to receive flow lines or flexible pipe can be connected end to end to form a riser assembly, and thereafter, the flow lines can be inserted through individual conduits of the assembly. The section contains a low density foam to impart essentially zero negative and positive buoyancy, and the foam is filled into areas surrounding the individual conduits of the sections. Suitable reinforcing and tension stress resisting elements are provided so that each section is essentially self sustaining.
