Offshore Floating Storage Vessel (FPSO) ndi chomera chamafuta chakunyanja chomwe chimaphatikizira kusungirako, kulekanitsa ndi kunyamula zinthu zamafuta opanda mafuta.Mafuta osakhwima opangidwa kuchokera ku zitsime zapansi pa nyanja amalandiridwa kudzera m'mapaipi apansi pa nyanja, amakonzedwa m'botimo ndikusungidwa m'matangi onyamula katundu, komwe amatumizidwa ku akasinja oyenda kudzera panjira yotsitsa.
Super duplex zitsulo zosapanga dzimbiri zimakhala ndi molybdenum, zomwe zimathandizira kwambiri kukana kwa dzimbiri kwa chitsulo chosapanga dzimbiri, chomwe ndi choyenera kwambiri kuti chigwiritsidwe ntchito nthawi yayitali m'malo okhala ndi ayoni ambiri a chloride, monga madzi a m'nyanja, ndipo amagwiritsidwa ntchito kwambiri mu mavavu otetezedwa, mapaipi. , nsanja za desulfurization ndi zigawo zina mu ma module a FPSO.
Makasitomala otere nthawi zambiri amakhala ndi zofunikira pakuyika zitsulo zazitsulo zowotcherera za super duplex zitsulo zosapanga dzimbiri (zofananira m'munsi zitsulo UNS S32750/S32760, etc.):

Pazinthu zowotcherera ndi zofunikira zaukadaulo za super duplex chitsulo chosapanga dzimbiri, kampani yathu ili ndi zowotcherera zofananira kuti zigwirizane, zomwe zikufotokozedwa motere:
