I-Offshore Floating Storage Vessel (FPSO) iyisikhungo sikawoyela esingasogwini esihlanganisa ukugcinwa, ukuhlukaniswa kanye nokuthuthwa kwemikhiqizo kawoyela ongahluziwe. Uwoyela ongahluziwe okhiqizwa emithonjeni engaphansi kolwandle utholwa ngamapayipi angaphansi kolwandle, ucutshungulwe ebhodini futhi ugcinwe emathangeni ezimpahla, lapho ekugcineni uthuthwa uyiswe ezinqoleni ezithutha amathangi ngohlelo lokuthulula.
Insimbi engagqwali eyi-Super duplex inokuqukethwe okuphezulu kwe-molybdenum, ethuthukisa kakhulu ukumelana nokugqwala kwensimbi engagqwali, efaneleka kakhulu ukusetshenziswa isikhathi eside ezindaweni ezinokuqukethwe kwe-ion ye-chloride ephezulu, njengamanzi olwandle, futhi isetshenziswa kabanzi kuma-valve okuphepha, amapayipi. , imibhoshongo ye-desulfurization nezinye izingxenye kumamojula we-FPSO.
Amakhasimende anjalo ngokuvamile anezidingo ezilandelayo zezakhiwo zensimbi zokubeka izinto ezisetshenziswayo zokushisela zensimbi engagqwali eyi-duplex (isisekelo sensimbi ehambisana ne-UNS S32750/S32760, njll.):
| Amandla okuqina (Mpa) | Ubude be-tensile (%) | I-Ferrite (Hlola) | Ukugqwala komgodi (40℃*24h) I-ASTM G48A | Ukuqina I-HV10 | inkomba ye-pitting I-PREN |
| ≥750 | ≥20 | 35-65% | ≤4g/m2 | ≤330 | ≥40 |
Ngezimpawu zokushisela kanye nezidingo zobuchwepheshe ezihlobene ze-super duplex insimbi engagqwali, inkampani yethu inezinto ezisetshenziswayo zokushisela ezihambisanayo ukuze zifane, ezichazwe kanje:
