  1. TRYKFAST PAKNING TIL DUKTILT JERN
    1. Fremgangsmåde til dannelse af en rørsamling, hvilken fremgangsmåde omfatter følgende trin: tilvejebringelse af et væskerørledningssystem, som indbefatter en række afsnit af duktile jernrør (17, 19), idet hvert af rørene (17) har en udvidet ende i én udstrækning med en mundregion (15), der støder op til en endeåbning deraf, hvor mundregionen (15) har en ringformet rille (13) deri, idet endeåbningen er dimensioneret til at modtage et tilsvarende inderrør (19) med en inderflade (21) og en yderflade (23); montering af en tætningspakning (11) i den ringformede rille (13), der er tilvejebragt i endeåbningen af den udvidede rørende, idet tætningspakningen (11) har en ringformet pakningskrop (25), som er fremstillet af et elastisk elastomert materiale med en defineret hårdhed, hvor den ringformede pakningskrop (25) har en forreste næseregion (27), en indre periferisk region (29) og en ydre periferisk region (31), idet den ringformede pakningskrop (25) er monteret i den ringformede rille (13), der er tilvejebragt i mundregionen (15) af det duktile jernrør (17), således at den ydre periferiske region (31) danner en tætning med den udvidede rørmundregion (15), og den indre periferisk region (29) danner en tætningsflade for yderfladen (23) af det tilsvarende duktile hanjernrør (19); hvor en flerhed af kileformede holderindsatser (37, 39) med højere hårdhed, hvilke indsatser er dannet ud fra et plastmateriale med en forholdsvis hårdere hårdhed end det elastomere materiale i den resterende pakningskrop (25), er monteret flytbart i og strækker sig udad fra den ringformede pakningskrop (25) langs den forreste næseregion (27) deraf med en forudbestemt afstand, som strækker sig omkring periferien af den ringformede pakningskrop (25), idet afstanden er tilstrækkelig til at tillade, at pakningskroppen (25) bøjes med henblik på at gøre montering af pakningskroppen (25) i den ringformede rille (13), der er tilvejebragt i mundåbningen af den udvidede rørende, nemmere; og hvor hver af de kileformede holderindsatser (37, 39) har en generelt kileformet næsedel (41) med modsatstillede skrånende sider, hvor de modsatstillede sider er dannet som glatte overflader, idet den kileformede næsedel (41) strækker sig udad fra den forreste næseregion (27) af pakningskroppen (25) til en apex set i tværsnit, og en bageste skafteregion (43), der udgør en fleksibel holderdel (45) til indsatsen (37, 39), idet den bageste skafteregion (43) har mindst to tapformede tilbageholdelsesstænger, der er monteret i egnede holderåbninger (47, 49) i næseregionen (27) af den ringformede pakningskrop (25) ved at trykke de tapformede tilbageholdelsesstænger ind i åbningerne (47, 49), hvorved der kan monteres alternative holderindsatser (37, 39) i den samme ringformede pakningskrop (25).
  2. 2. Fremgangsmåde ifølge krav 1, der endvidere omfatter de trin, at der derefter monteres et tilsvarende inderrør (19) i endeåbningen af mundregionen (15) i den udvidede rørende, idet tætningspakningen (11) berører den ydre flade af det tilsvarende inderrør (19) med henblik på at danne en tætnet forbindelse for rørene (17, 19) og danne en sikker samling.
  3. 3. Fremgangsmåde ifølge krav 2, hvor det tilsvarende inderrør (19) har en forreste næseregion (53), og hvor den forreste næseregion (53) af det tilsvarende inderrør (19) berører holderindsatserne (37, 39) inden berøring med resten af den elastomere pakningskrop (25).
  4. 4. Fremgangsmåde ifølge krav 3, hvor holderindsatserne (37, 39) er dannet af et af acrylonitrilbutadienstyren fremstillet plastmateriale med en Shore A-hårdhed i intervallet fra 75 til 95, hvorved holderelementerne (37, 39) fungerer med henblik på at forhindre pakningskroppen (25) i at blive blæst ud af den udvidede rørende under højt tryk.
