Iinkalo zokusetyenziswa kwee-alloys ezikhethekileyo kushishino lwepetroleum:
Ukuhlolwa kwe-petroleum kunye nophuhliso luluhlu lwezinto ezininzi, iteknoloji-intensive kunye ne-capital-intensive industry kufuneka idle inani elikhulu lezinto zetsimbi kunye neemveliso ezineepropati ezahlukeneyo kunye nokusetyenziswa. Ngokuphuhliswa kwe-ultra-deep kunye ne-ultra-inclined oil and gas sources kunye ne-oyile kunye ne-gas fields equkethe i-H2S, i-CO2 kunye ne-Cl -, ukusetyenziswa kwezixhobo zensimbi ezingenasici kunye neemfuno zokusebenza ezichasene ne-corrosion ziyanda.
Uphuhliso lweshishini lepetrochemical kunye nokuhlaziywa kwezixhobo zepetrochemical zibeke phambili iimfuno eziphezulu kumgangatho kunye nokusebenza kwentsimbi engatyiwa. Iimfuno zokumelana ne-corrosion, ukumelana nobushushu obuphezulu kunye nokumelana nobushushu obuphantsi bensimbi engenasici ayiphumli kodwa ingqongqo. Ngelo xesha, imboni yepetrochemical iphinde ibe nobushushu obuphezulu, uxinzelelo oluphezulu kunye noshishino olunobuthi, olwahlukileyo kwamanye amashishini. Imiphumo yezinto zokuxuba izinto azibonakali. Nje ukuba umgangatho wezinto zensimbi ezingenasici kwishishini lepetrochemical ungaqinisekiswa, iziphumo aziyi kucingelwa, Ke ngoko, amashishini entsimbi yasekhaya, ngakumbi amashishini emibhobho yentsimbi, kufuneka aphucule umxholo wobugcisa kunye nexabiso elongeziweyo leemveliso ngokukhawuleza kangangoko kunokwenzeka ukuba athathe indawo yokuhlala. imarike yemveliso ephezulu.
Idla ngokusetyenziswa kwiireactors kwizixhobo zepetrochemical, iityhubhu zeoyile, iibhubhu ezipolishiweyo kwimithombo yeoli eyonakalisayo, iityhubhu ezijikelezayo kwiziko lepetrochemical, kunye namacandelo kunye nezixhobo zokomba ioyile nerhasi.
