Abstract
Forsegling av polymermateriale og beregnet for å tette et hull l en rør- ledning eller i en polymerkappe utenpå et rør e.l., særlig i forbindelse med fordelingssystemer for fjernvarme. For- seglingen av polymermateriale omfatter et støttelag (2), et varmeaktiverbart bindelag (4) for å feste forseglingen til den kappe eller det beskyttelsesrør som skal tettes, og et elektrisk opp- varmbart lag som kan være et separat lag eller inngå i bindelaget (4). Et ytter- ligere lag (8) av polymermateriale kan være lagt inn i forseglingen lengst unna støttelaget (2) når det substrat som skal tettes tselv ikke er av polymermate- riale. Lagene kan ha sin separate funk- sjon eller ett av lagene kan ha flere funksjoner. Et verktøy (22, 24, 26 - fig. 5) kan også være anordnet for even- tuelt, å forbedre tetningen av hullet i substratet ved hjelp av forseglingen og en tilhørende fremgangsmåte for bruken av denne.Sealing of polymeric material and intended to seal a hole in a pipeline or in a polymer sheath on the outside of a pipe or the like, especially in connection with district heating distribution systems. The polymer material sealing comprises a support layer (2), a heat-activatable adhesive layer (4) for attaching the seal to the sheath or protective tube to be sealed, and an electrically heatable layer which may be a separate layer or form part of the adhesive layer ( 4). An additional layer (8) of polymeric material may be inserted into the seal furthest from the backing layer (2) when the substrate to be sealed itself is not of polymeric material. The teams may have their separate function or one of the teams may have several functions. A tool (22, 24, 26 - Fig. 5) may also be provided for optionally improving the sealing of the hole in the substrate by means of the seal and an associated method for its use.
