Claims (10)
1. Rør (1) omfattende en ytre kappe (3),
karakterisert ved at den ytre kappen (3) er arrangert i en avstand rundt røret (1), slik at det dannes et ringrom (4) mellom røret og kappen, og ved at ringrommet (4) omfatter granulært materiale (5) med en egenvekt høyere enn vann, idet ringrommet er kontinuerlig slik at det granulære materialet kan fordeles likt rundt røret, og ved at sentrerende elementer (7) er arrangert mellom røret og kappen, ved hver ende av kappen (3).
2. Rør i samsvar med krav 1, karakterisert ved at kappen er et annet rør.
3. Rør i samsvar med krav 1 eller 2, karakterisert ved at rørene er fremstilt av polyetylen, fortrinnsvis med en tetthet over 0.9.
4. Rør i samsvar med krav 1, karakterisert ved at avstanden mellom kappen og røret bør være minst to ganger gjennomsnittlig størrelse av det granulære materialet, fortrinnsvis minst 3 ganger gjennomsnittlig størrelse.
5. Rør i samsvar med et av de foregående krav, karakterisert ved at gjennomsnittlig størrelse av det granulære materialet er 2-6 mm.
6. Rør i samsvar med et av de foregående krav, karakterisert ved at det granulære materialet er et mineral, fortrinnsvis Olivine og/eller barytt.
7. Rør i samsvar med et av de foregående krav, karakterisert ved at et endestykke (6) er kombinert med de sentrerende elementene (7), og arrangert ved hver ende av kappen (3)
8. Framgangsmåte for å justere vekten av et rør i samsvar med et av kravene 1-7, idet framgangsmåten omfatter følgende trinn:
i) åpne en inngang til ringrommet (4),
ii) fjerne eller tilføre granulært materiale (5) til ringrommet (4), og
iii) lukke inngangen til ringrommet.
9. Framgangsmåte i samsvar med krav 8, idet røret har et endestykke (6) kombinert med sentrerende elementer (7), framgangsmåten omfatter ytterligere trinn for å - innføre sentrerende elementer mellom røret og kappen før trinn ii), og - fjerne sentrerende elementer etter trinn ii).
10. Framgangsmåte i samsvar med krav 8, idet trinnet for å tilføre granulært materiale til ringrommet, omfatter blåsing.
