Ishubhu Elingenamthungo Lensimbi Engagqwali engu-309
Incazelo emfushane:
Insimbi Engagqwali 309 iyinsimbi engagqwali e-austenitic engagqwali engashisi kakhulu enokuqukethwe okuphezulu kwe-chromium kanye ne-nickel.
Ukuhlolwa kwe-Hydrostatic Pipe yensimbi engagqwali:
Insimbi Engagqwali 309 yaziwa ngokumelana kwayo nokushisa okumangalisayo, okwenza ifaneleke ukusetshenziswa lapho ukuchayeka emazingeni okushisa aphezulu kuvame khona. Ingxubevange inikeza ukumelana okuhle nokugqwala, ikakhulukazi ezindaweni ezingcolisa kancane. Okuqukethwe okuphezulu kwe-chromium kanye ne-nickel kunegalelo ekumelana nokugqwala kwengxubevange kanye namandla okushisa aphezulu. Igama elithi "okungagqwali" lisho ukuthi ithubhu likhiqizwa ngaphandle kwemithungo ehlanganisiwe. Amashubhu angenamthungo avame ukuthandwa ekusetshenzisweni okunomfutho ophezulu kanye nokushisa okuphezulu ngenxa yesakhiwo sawo esifanayo. Amashubhu angenamthungo ensimbi Engagqwali 309 athola ukusetshenziswa ezimbonini ezahlukahlukene, kufaka phakathi izindiza, ukucubungula amakhemikhali, ukucubungula ukushisa, nokuningi, lapho kuhlangana khona amazinga okushisa aphezulu kanye nezindawo ezingcolisa.
