Imininingwane Yomkhiqizo
Imikhono ye-Stellite alloy valve isetshenziswa kakhulu emkhakheni wokumba i-petroleum. Indawo yokusebenza nezimo zemboni yokumba i-petroleum zinzima kakhulu. Ngokuqondile, amanzi, amagesi ahlukahlukene, i-wax, isihlabathi nezinye izinto ezigqwala kakhulu ngokuvamile zikhona emithonjeni ekhiqiza isihlabathi, imithombo kawoyela esindayo kanye nemithombo yegesi elwa nokucindezela okuphezulu kwe-condensate. Amaphampu wemithombo kawoyela ayadingeka ukuze kukhishwe uwoyela ekujuleni okungamakhulu noma izinkulungwane zamamitha, okubeka izidingo eziqinile ezingxenyeni zawo ukuze kufakwe uphawu oluhle kakhulu, ukumelana nokugqoka kanye nokumelana nokugqwala. Imikhono yevalvu ye-Stellite alloy ekhiqizwa ngokunemba kokucindezela komkhathi, ukukhishwa kwe-vacuum ngokunemba kanye nezinqubo ze-powder metallurgy zingahlangabezana ngokugcwele nezimfuneko zesevisi ezinzima ezingenhla.
Izinkambu Zohlelo
Imikhono ye-Stellite alloy valve isetshenziswa kakhulu kumavalvu afana nama-ball valve, ama-oil pump valve kanye nama-fluid valves.
Izinzuzo kanye Nezinsizakalo
Inkampani yethu yamukela ukunemba kokusakazwa kanye nezinqubo ze-powder metallurgy zokukhiqiza ngobuningi bemikhiqizo yemikhono yamavalvu. Le mikhiqizo ifaka ukusebenza okuzinzile kanye nempilo ende yesevisi, okusiza ukunciphisa isikhathi sokungasebenzi kwemishini kanye nezindleko zokunakekela eziphansi.
