  • 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.
    Type: Grant

  • Apparatus and methods of improving riser weld fatigue
    Patent number: 7897267
    Abstract: A tubular assembly comprising a first iron based tubular having a first non-cladded inner surface; and a second iron based tubular having a second non-cladded inner surface, wherein the first tubular is connected to the second tubular using a non-iron based bonding material. Preferably, the non-iron based bonding material has a lower crack growth rate than the iron based tubulars.
