Ko Offshore Floating Storage Vessel (FPSO) he tipu hinu o waho o te takutai e whakakotahi ana i te rokiroki, te wehe me te kawe i nga hua hinu hinu. Ko te hinu hinu mai i nga puna o raro o te moana ka riro mai i roto i nga paipa o raro o te moana, ka tukatukahia i runga i te kaipuke, ka penapena ki roto i nga taika utauta, ki reira ka haria atu ki nga waka taika ma te punaha whakaheke.
Super duplex kowiri tira he nui te ihirangi molybdenum, e tino whakapai ake i te parenga waikura o te kowiri tira, e tino pai ana mo te whakamahi mo te wa roa i roto i nga taiao me te ihirangi katote chloride teitei, penei i te wai moana, a ka whakamahia nuitia i roto i nga waahi haumaru, pipeline. , pourewa desulfurization me etahi atu waahanga i roto i nga waahanga FPSO.
Ko enei kaihoko ko nga whakaritenga e whai ake nei mo te whakaurunga o nga taonga whakarewa o nga taonga whakarewa o te super duplex kowiri tira (whakaritea te whakarewa turanga UNS S32750/S32760, etc.):
| Te kaha tensile（Mpa） | Te roa tensile (%) | Ferrite (Whakamātautau) | Te waikura poka (40℃*24h) ASTM G48A | Te pakeke HV10 | taupū rua PREN |
| ≥750 | ≥20 | 35-65% | ≤4g/m2 | ≤330 | ≥40 |
Mo nga ahuatanga whakahiato me nga whakaritenga hangarau e pa ana ki te super duplex kowiri tira, kei ta maatau kamupene nga taonga taapiri e rite ana ki te whakarite, e whakaahuahia ana e whai ake nei:
