Abstract
System for strømningssikring som omfatter et indre rør (70) anordnet i et ytre rør (50) for å sikre strømning gjennom det ytre rør (50). Under installasjon og relativ aksial bevegelse i forhold til ytre rør (50) har det indre rør (70) en tilnærmet eller helt nøytral oppdrift i fluidene i det ytre rør (50) og kan strekke seg helt eller delvis gjennom ytre rør (50). Det indre rør (70) kan være forankret ved en ende i forhold til ytre rør (50). Det indre rør (70) er fortrinnsvis et kompositt kveilrør som blir installert med et fremdriftssystem. Systemet kan tillate fluider å strømme gjennom de indre rør (70) og bli blandet med fluider i ytre rør (50) eller kan strømme gjennom indre rør (70) til utsiden av ytre rør (50). Varme fluider kan sendes gjennom indre rør (70) for å opprettholde temperaturen av fluider som strømmer i det ytre rør (50) og kjemikalier kan strømme gjennom indre rør (70) for å kondisjonere fluidene i ytre rør (50). Verktøy kan festes til enden av indre rør (70) for å gjennomføre strømningssikrende operasjoner inne i ytre rør (50).Flow protection system comprising an inner tube (70) arranged in an outer tube (50) to ensure flow through the outer tube (50). During installation and relative axial movement relative to outer tubes (50), the inner tubes (70) have an approximate or completely neutral buoyancy in the fluids of the outer tubes (50) and may extend wholly or partially through outer tubes (50). The inner tube (70) may be anchored at one end relative to the outer tube (50). The inner tube (70) is preferably a composite coiled tube which is installed with a propulsion system. The system may allow fluids to flow through the inner tubes (70) and be mixed with fluids in outer tubes (50) or may flow through inner tubes (70) to the outside of outer tubes (50). Hot fluids can be passed through inner tubes (70) to maintain the temperature of fluids flowing in the outer tubes (50) and chemicals can flow through inner tubes (70) to condition the fluids in outer tubes (50). Tools can be attached to the end of inner tubes (70) to perform flow-proofing operations inside outer tubes (50).
