Abstract

Fremgangsmåte for å isolere en invendig del av en rørledning fra en annen innvendig del av rørledningen. Et legeme av frysbart, gelet hydro-karbon som omfatter voks, innføres i rørledningen, legemet transporteres gjennom rørledningen til et sted ved, eller nær ved, den ønskede innvendige del av rørledningen og legemet fryses ved anvendelse av frysemidler slik at det dannes en plugg av fryst mate-riale.Method for isolating an inner part of a pipeline from another inner part of the pipeline. A body of freeze-gelled hydrocarbon comprising wax is introduced into the pipeline, the body is transported through the pipeline to a location near, or near, the desired inner portion of the pipeline and the body is frozen using freezing agents to form a plug of frozen material.
