Ehlobo elishisayo, imboni imatasa ikhiqiza imisebenzi ehlukahlukene yamavalvu. Ezinsukwini ezimbalwa ezedlule, ifekthri yakwaJinbin iqedele elinye i-task order elivela e-Iraq. Leli qoqo lesango lamanzi liyinsimbi engagqwali engu-304isango le-sluice manual, ephelezelwa ubhasikidi we-stainless steel drain 304 onomzila wesitimela wamamitha angu-3.6. I-welding ye-valve stem ihlanzwa nge-ultrasonic acid ukususa amabala.

Ukusetshenziswa kwezinto ezingama-304 zensimbi engagqwali ukwenzai-penstockinezinzuzo ezilandelayo:

304 insimbi engagqwali iqukethe ingxenye ephezulu ye-chromium ne-nickel, engamelana nokuguguleka kwemithombo yezindaba yamakhemikhali ehlukahlukene, okuhlanganisa ama-asidi, ama-alkali, nosawoti. Ilungele ikakhulukazi izindawo ezingase zihlangane nendle namanzi olwandle, futhi ingagcina ukuqina kwesakhiwo kanye nezakhiwo zemishini ezindaweni ezishisayo, okuyenza ifaneleke izimo zokusebenza ezisezingeni eliphezulu.

Insimbi engagqwali engu-304 kulula ukuyicubungula nokubunjwa, ifanele ukukhiqiza amasango ahlukahlukene anomumo oyinkimbinkimbi, futhi kulula ukuhlangabezana nezidingo zokuklama kobunjiniyela. Le nto inokumelana nokugqokwa okuhle, ingamelana nokugqoka nokuklwebheka, igcine ubushelelezi bendawo kanye nobuhle, futhi inamandla aphezulu kanye nokuqina endaweni yokushisa yasekamelweni, iqinisekisa ukwethembeka nokuphepha kwesango ezinhlelweni ezihlukahlukene zobunjiniyela.

Ubuso bensimbi engagqwali engu-304 bushelelezi futhi bufana, bunezici ezinhle zokuhlobisa nezobuhle, ezifanele izinhlelo zokusebenza ezinezidingo eziphezulu zokubukeka. Ingenza ifilimu ye-oxide eminyene ebusweni emoyeni, ivimbele ngempumelelo i-oxidation yensimbi nokugqwala, futhi yandise impilo yesevisi. Ayiqukethe izakhi zensimbi ezisindayo eziyingozi emzimbeni womuntu, ihlangabezana nezindinganiso zenhlanzeko nokuphepha, ifanele ukucubungula ukudla, izinsiza zezokwelapha nezinye izinkambu, iwumsebenzi ongasetshenziswa kabusha, ivumelana nemvelo, futhi ivumelana nomqondo wentuthuko esimeme. Ngenxa yokumelana nokugqwala nokumelana nokugqoka kwensimbi engagqwali engu-304, izindleko zokugcinwa kwesango ziphansi kakhulu.

Lezi zinzuzo zenza insimbi engagqwali engu-304 ibe inketho ekahle yokukhiqizaama-valve odonga lwe-penstock, ikakhulukazi kubunjiniyela be-hydraulic, ukuthuthwa kwendle, kanye nezindawo zasolwandle, ukuqinisekisa ukusebenza okuzinzile kwesikhathi eside kanye nezidingo eziphansi zokugcinwa kwamasango. Uma unayoisango le-sluiceizidingo zempahla ye-valve, sicela usithinte ngezansi futhi uzothola impendulo kungakapheli amahora angama-24.
