Izinkambu zokufaka izicelo zama-alloys akhethekile embonini ye-petroleum:
Ukuhlola nokuthuthukiswa kwe-petroleum kuyimboni enezigwegwe eziningi, edinga kakhulu ubuchwepheshe futhi idinga imali eningi edinga ukudla inani elikhulu lezinto zensimbi nemikhiqizo enezakhiwo nokusetshenziswa okuhlukile. Ngokuthuthukiswa kwemithombo ye-ultra-deep ne-ultra-inclined kawoyela negesi kanye nezinkambu zikawoyela negesi eziqukethe i-H2S, i-CO2 ne-Cl -, ukusetshenziswa kwezinto zensimbi engagqwali ezinezidingo zokusebenza kwe-anti-corrosion kuyanda.
Ukuthuthukiswa kwemboni ye-petrochemical kanye nokuvuselelwa kwemishini ye-petrochemical kubeke phambili izidingo eziphakeme zekhwalithi nokusebenza kwensimbi engagqwali. Izidingo zokumelana nokugqwala, ukumelana nokushisa okuphezulu nokumelana nokushisa okuphansi kwensimbi engagqwali akukhululekile kodwa kuqinile. Ngesikhathi esifanayo, imboni ye-petrochemical nayo iyizinga lokushisa eliphezulu, ingcindezi ephezulu kanye nemboni enobuthi, ehlukile kwezinye izimboni. Imiphumela yokuxuba izinto azibonakali. Lapho ikhwalithi yezinto zensimbi engagqwali embonini ye-petrochemical ayinakuqinisekiswa, imiphumela izoba yinto engacabangeki, Ngakho-ke, amabhizinisi ensimbi engenasici, ikakhulukazi amabhizinisi amapayipi ensimbi, kufanele athuthukise okuqukethwe kwezobuchwepheshe kanye nenani elengeziwe lemikhiqizo ngokushesha ngangokunokwenzeka imakethe yemikhiqizo ephezulu.
Okuvame ukusetshenziswa kuma-reactor kumishini ye-petrochemical, amashubhu omthombo kawoyela, izinduku ezipholishiwe emithonjeni kawoyela egqwala, amashubhu asondekile ezithandweni ze-petrochemical, kanye nezingxenye kanye nezingxenye kumishini yokumba kawoyela negesi.
Ama-alloys akhethekile avame ukusetshenziswa embonini ye-petroleum:
