Abstract
En ekspanderbar pakning som inneholder et svellende lag (22) beskrives. Det svellende lag kan tildannes integrert med eller festet til et ekspansjonselement (18) eller det kan være bundet eller på annen måte festet til en spindel (16). Etter ekspansjon med fluid (26), ekspanderer elementet til tettende kontakt med et omgivende rør eller borehull. Fluidet absorberes eller reagerer gjensidig med det svellende lag, slik at i en foretrukket utførelsesform bibeholdes det totalt opptatte volum av det svellende lag og fluidet etter sammenføringen, hvor svellingen av laget virker til å opprettholde tetningen av det ekspanderbare element selv om det opptrer et problem i tetningselementet.
