  • Conduit system and method of use thereof
    Patent number: 10400936
    Abstract: Conduit system for conveying fluids is described. The conduit system comprises a conduit, a tubular, and a sealing component. The tubular is positioned radially interior of an inner surface of the conduit along a length. The tubular comprises a polymeric material. The sealing component is positioned proximate the distal end of the tubular in an annulus formed between an outer surface of the tubular and the inner surface of the conduit, the sealing component constructed and arranged to seal the annulus. Methods for reducing corrosion of or providing pressure integrity to a conduit are also described.
    Type: Grant
    Filed: March 8, 2018
    Date of Patent: September 3, 2019
    Assignee: ExxonMobil Upstream Research Company

  • Flexible pipe with corrosion resistant layer
    Patent number: 10207455
    Abstract: The present techniques are directed to a flexible pipe. An inner carcass layer forms the innermost layer of the flexible pipe. An inner sheath layer and an outer sheath layer are disposed externally of the inner carcass layer. A layer of corrosion resistant alloy is disposed at any location between the inner carcass layer and the outer sheath layer. At least one armor layer is disposed internally of the outer sheath layer.

  • Method and System For Inspecting A Pipe
    Publication number: 20170176343
    Abstract: Methods and systems for identifying defects in pipes are provided. An example method for inspecting one or more metal structures in a pipe includes heating the pipe and placing an infrared (IR) sensor proximate to a surface of the pipe to obtain IR images of the pipe. Any defects are identified in at least one of the one or more metal structures in the IR images.
