Claims (13)
1. Fleksibelt rør for transportering av en petroleumseffluent omfattende vann og minst en sur forbindelse fra karbondioksid CO2 og hydrogensulfid H2S, nevnte rør omfatter minst ett mekanisk forsterkende metallelement (3, 5) og en trykkmantel (2), nevnte metallelement (3, 5) er anbragt på utsiden av nevnte trykkmantel (2), en diffusjonsbarriere (B) er anbragt mellom nevnte mantel for motstand mot trykk (2) og nevnte mekanisk forsterkende metallelement (3, 5), karakterisert ved at nevnte diffusjonsbarriere (B) omfatter minst ett metallbånd (F) viklet rundt nevnte mantel for motstand mot trykk (2) for slik å tilveiebringe en metalloverlapping over en avstand på mellom 35 % og 75 % av bredden av nevnte metallbånd (F) og ved at et polymermateriale (P) er innsatt i denne overlappingen.
2. Rør ifølge krav 1, hvori nevnte metallbånd (F) er dekket, i det minste delvis, med et lag av nevnte polymermateriale (P) på minst én flate.
3. Rør ifølge krav 1, hvori nevnte diffusjonsbarriere (B) er dannet av nevnte metallbånd (F) og av et bånd av nevnte polymermateriale (P).
4. Rør ifølge krav 3, hvori nevnte bånd av nevnte polymermateriale (P) har en bredde som er hovedsakelig lik bredden av nevnte metallbånd (F).
5. Rør ifølge et av de foregående kravene, hvori nevnte metallbånd (F) er laget av rustfritt stål, laget av karbonstål eller laget av legering av nikkel, titan eller aluminium.
6. Rør ifølge et av de foregående kravene, hvori nevnte polymermateriale (P) i nevnte diffusjonsbarriere (B) er en elastomer eller en termoplastisk polymer valgt fra følgende klasser: NBR (butadien/akrylnitril-kopolymer), CR (polykloropren, neopren), EPDM (etylen/propylen/dien-monomer), CO (polyklormetyloksiran), TFE (tetrafluoretylen), PU (polyuretan), silikon, PE (polyetylen), PA (polyamid) eller PVDF (polyvinylidenfluorid).
7. Rør ifølge et av de foregående kravene, hvori nevnte diffusjonsbarriere (B) omfatter minst to lag av metallbånd (F) viklet flatt, hvor det andre laget av metallbånd (F) danner nevnte overlapping.
8. Rør ifølge et av kravene 1 til 6, hvori nevnte diffusjonsbarriere (B) omfatter minst ett lag av metallbånd (F) viklet på S-måte for å danne nevnte overlapping.
9. Rør ifølge et av kravene 1 til 6, hvori nevnte diffusjonsbarriere (B) omfatter minst ett lag av metallbånd (F) viklet på "dobbel S"-måte for å danne nevnte overlapping.
10. Rør ifølge et av de foregående krav, hvori nevnte diffusjonssperre (B) har en bredde på mellom 25 og 150 mm.
11. Rør ifølge et av de foregående krav, hvori laget av nevnte polymermateriale (P) av nevnte diffusjonsbarriere har en tykkelse på mellom 0,5 mm og 4 mm.
12. Rør ifølge et av de foregående kravene, hvori nevnte metallbånd (F) av nevnte diffusjonsbarriere (B) har en tykkelse på mellom 0,2 mm og 2 mm.
13. Rør ifølge et av kravene, hvori et elastomerlag er innført mellom nevnte diffusjonsbarriere (B) og nevnte mekanisk forsterkende metallelement (3, 5).
