446 Ipayipi lensimbi engagqwali
Incazelo emfushane:
Thola amapayipi ensimbi angama-446 angenasici ngokumelana okuphezulu okuphezulu nokugqwala. Ilungele izinhlelo zokusebenza zezimboni.
Ukuhlolwa Kwensimbi Engagqwali:
446 Ipayipi lensimbi engagqwali liyinsimbi engenacala elingenacala elibonakaliswa okuqukethwe kwalo okuphezulu kwe-chromium, enikeza ukumelana nokuvimbela i-oxidation ephezulu kakhulu kanye nokuphikiswa kokugqwala. Ngenxa yokwakheka kwayo okuhlukile kwe-alloy, ipayipi lensimbi engenasici lisebenza kahle ngaphansi kwezimo zokushisa ezedlulele, okwenza kusetshenziswe kabanzi kumishini yezimboni ephezulu, ama-boilers, amakamelo okushisa kanye namakamelo okushisa. Ngokwengeziwe, ngenxa yokumelana kwayo okunamandla okukhulu, ipayipi lensimbi engenasici livame ukusetshenziswa kwizicelo zobunjiniyela zamakhemikhali, zikaphethiloli. Ngokukhetha ipayipi lensimbi engu-446 engenasici, uzothola ikhwalithi yomkhiqizo evelele nokusebenza okuthembekile ukuze uhlangabezane nezidingo zezicelo ezahlukahlukene ezinzima.

Izicelo ezingama-446 zensimbi ezingagqwali:
446 Amapayipi ensimbi engagqwali asetshenziswa kabanzi ezindaweni ezahlukahlukene ezifunwayo ngenxa yokungamelana nokushiswa kokushisa okuphezulu kakhulu nokugqwala. Emishini yezimboni, zivame ukusetshenziswa emampandeni, abashiseli bokushisa, nama-boilers. Ezimbonini zamakhemikhali kanye ne-petrochemical, zilungele ukuthutha uketshezi olushisa kakhulu. Umkhakha wamandla uwasebenzisa ezitshalweni zamandla kanye nemboni yenuzi. E-Marine Engineering, amapayipi ensimbi angama-446 asetshenziswa ezinhlelweni zamanzi olwandle namapulatifomu aphesheya. Ngaphezu kwalokho, badlala indima enkulu ekwakheni, izimoto, i-aerospace, kanye nezimboni zokuphuza izimboni, ukuba yinto elungele ukubulawa kwabantu okushisa kanye nokuhamba okushisayo koketshezi. Lezi zici zibenza babe ukukhetha okuthembekile kwezicelo ezahlukahlukene eziphezulu.
