I-Offshore Floating Storage Vessel (FPSO) sisixhobo se-oyile esisebenza kude nonxweme esidibanisa ukugcinwa, ukwahlula kunye nokuthuthwa kweemveliso ze-oyile ekrwada. I-oyile ekrwada eveliswa kumaqula angaphantsi kolwandle ifunyanwa ngemibhobho engaphantsi kolwandle, isetyenzwe ebhodini ize igcinwe kumatanki omthwalo, apho ithi ekugqibeleni ithuthwe isiwe kwiinqwelo zeetanki ezithuthwayo ngenkqubo yokothula.
I-Super duplex steel stainless inomxholo ophezulu we-molybdenum, ophucula kakhulu ukuxhathisa kwe-corrosion yensimbi engenasici, efanelekileyo kakhulu ekusebenziseni ixesha elide kwiindawo ezinomxholo ophezulu we-ion ye-chloride, njengamanzi olwandle, kwaye isetyenziswa ngokubanzi kwiivalvu zokhuseleko, imibhobho. , iinqaba ze-desulfurization kunye namanye amacandelo kwiimodyuli zeFPSO.
Abaxumi abanjalo ngokubanzi banezi mfuno zilandelayo kwiipropathi zetsimbi ze-welding ze-welding consumables ze-super duplex steel stainless (isiseko esihambelana ne-metal UNS S32750 / S32760, njl.):
| Amandla okuqina (Mpa) | Ubude be-tensile (%) | Ferrite (Vavanya) | Ukubola kombhobho (40℃*24h) I-ASTM G48A | Ukuqina HV10 | isalathisi sokubhoboza I-PREN |

Ngeempawu zokuwelda kunye neemfuno zobuchwepheshe ezinxulumene ne-super duplex yensimbi engenasici, inkampani yethu inezixhobo ezihambelana ne-welding ezihambelanayo, ezichazwe ngolu hlobo lulandelayo:
