20090050228 | STABILIZED FLEXIBLE PIPE FOR TRANSPORTING HYDROCARBONS - The invention relates to a flexible pipe for transporting hydrocarbons, comprising the following, from the inside towards the outside: a cylindrical structural set adapted in such a way that it can withstand radial stress and at least one first armure lap, said first armure lap comprising a plurality of armure threads wherein the armure threads consist of formed and flattened metal threads, the width of said armure I being greater than the thickness e when they are wound in parallel in the form of a spiral with a longitudinal pitch around the structure set, said threads forming an angle of less than 60° angle with the generators (G) of said structural set, and the width/thickness ratio of the armure threads is greater than 4. | 02-26-2009 |
20100018717 | FLEXIBLE RISER PIPE INSTALLATION FOR CONVEYING HYDROCARBONS - The invention relates to a riser pipe installation that comprises a flexible duct of the non-bound type, the duct being vertically arranged between a mechanical connection with a submerged buoy at the stub on the one hand, and a mechanical connection with the seabed at the bottom on the other hand, wherein fluid connections are provided at the stub and at the bottom for connecting the riser pipe with surface equipment on the one hand and bottom equipment on the other hand; the bottom of the pipe is located at a depth of at least 1000 m where it is submitted to a computable maximum reverse bottom effect F, while the buoy is oversized in order to generate at the bottom of the riser pipe a reaction tension T higher than at least 50% or even 100% of the computable maximum reverse bottom effect F applied at the bottom of the pipe. | 01-28-2010 |
20100089481 | FLEXIBLE PIPE HAVING HIGH RESISTANCE TO AXIAL COMPRESSION AND METHOD OF MANUFACTURING SUCH A PIPE - A flexible pipe and a method of producing it. The pipe has two tubular structures, internal and external, and a tubular axial blocking layer. The tubular blocking layer comprises two section wires each having a trapezoidal cross section. The trapezoidal cross section defines a base and two sloping lateral flanks. The base of one of the two section wires is oriented toward the internal tubular structure. The base of the other section wire is oriented in the opposite direction. The section wires are wound side by side forming contiguous coils. The internal tubular structure comprises a wire having a wound structure to form transversely blocked coils. One of said two section wires is wound against said structure coils. | 04-15-2010 |
