20060207672 - Method and a device for slowing down and disintegrating a plug of liquid plunging forward in a duct: A device for slowing down and disintegrating a plug of liquid plunging forward in a duct includes a container having a bottom and an opposite inlet, which is connectable to the duct and through which the plug of liquid can be directed into a central, axial trajectory in the container....

20060207673 - Vacuum insulated assured flow piping: An assured flow conduit has an inner conduit having an inner diameter sized to accommodate a flow of warm fluid and an outer diameter. The inner conduit is formed from a material having a low hydrogen content. An outer conduit encloses the inner conduit and has an inner diameter larger...

20060201564 - Riser installation from offshore floating procuction unit: A method for installing risers so they extend from a FPU (floating production unit) to multiple subsea hydrocarbon wells of an oil field, which avoids damage to the pipe sections and that is economical. As pipe sections are connected to a near end (56) of a pipe string portion (68B-68D)...

20060201565 - Pipe system: The invention relates to a pipe system comprising four pipes or tubes each with external corrugations. The pipes also have an end sleeve or connector joint. As in the first embodiment, the pipes of the system are supported in a desired array by an initially separate support, comprising in use...

20060201566 - Hose with integral coupling and method for producing the same: The invention relates to a hose that comprises at least one inner layer (1) produced from an elastomer material, an embedded reinforcement carcass produced from a textile and/or metal material, an outer layer produced from an elastomer material and a coupling having a flange section inside the hose end. The...

20060201567 - Corrugated pipe with outer layer: A pipe having an axially extending bore is defined by a pipe wall including a corrugated outer wall having axially adjacent annular outwardly-extending crests separated by valleys. The pipe wall also includes a non-linear outer layer having adjacent concave portions and convex portions. The concave portions are aligned with the...

20060201568 - Flexible, tubular device e.g. a bellows: The present invention concerns a flexible, tubular device e.g. a bellows with an internal diameter up to 60 millimeters, said device comprising one or more corrugated convolutions (2), said convolutions having an overall bell-like shape with rounded top portions (T) and rounded bottom portions (B,B′). The novel aspects involve that...

20060201569 - Hose made of thermoplastic polymer: The invention relates to a hose made of a thermoplastic polymer comprising a core and a cover provided with a reinforcement, in particular in the form of a multilayer reinforcing structure, wherein each core and cover consists of a thermoplastic polymer and wherein, according to the invention, an intermediate coupling...

20060201570 - Methods and systems for enhanced fluid transport: Methods and systems for a flexible hose assembly are provided. The flexible hose assembly includes a core tube including a substantially fluid-impervious body including an inner surface and an outer surface, and an aramid sleeve including aramid yarn, the aramid sleeve circumferentially covering the core tube....

20060196568 - Flexible, compression resistant and highly insulating systems: A system for insulating and providing structural support to pipelines is presented. The system is lightweight and can be constructed to withstand large compressive forces and is applicable to transport of hydrocarbons such as crude oil, gas and LNG including sub-sea applications....
