Kana vagadziri vanoda kuvandudza mhando yePlapeline, saka zvinoparadzanisa corrostion idambudziko rekukundwa mupombi yekugadzira pombi.

Isu tinonyatsowana rudzi rusingaoneki rwechirwere chekushambadzira chinodaidzwa kuyamwiswa corrostion (IGC) kuti tinzwisise kuti kupindira sei kupindirana kwekuita uye kuongorora uye kuderedza kukuvara.

Chii chinogunun'una corroson?

Muzvishandiso zvemhando yepamusoro, kuyaruka corrostion (IGC), kunozivikanwawo sekurwiswa kwekunyepedzera (IGA), chimiro cheuto uko miganhu yezvinyorwa zvacho zvinowanzoshamisira kupfuura zvoga. Kubatanidza Corrostion (zvakare kunozivikanwa kuora) kunokanganisa simbi isina tsvina pane imwe nhanho uye inogona kusaratidza zviratidzo zvinooneka zvekukuvara kusvikira kuenderera mberi kwakanyanya.

Nei kuwirirana kuenderana kukaitika?

Muchidimbu, kupindirana kurongeka kunokonzerwa neWalking yePIPES, kurapa kwakashata kupisa, uye kufumurwa pakati pe245 uye 870 degrees celsius.

Kana simbi mukudziya kweiyi renji, inoshanduka pane imwe nzvimbo yekuumbwa. Iyo Chromium iripo muAlloy inobata neCarbon yekugadzira Chromdius carbide pedyo neiyo gidhi muganho. Iyi fomu yekuumbwa ine carbidaly inoshandura muganho muAnode masero. Crystal zvimedu mukati meCathode Masero, uye Corrosion Kutanga.

Nzira dzekuderedza kuyamwisa corroson?

Kurapa kwehunyanzvi kunogona kugadziriswa nedambudziko, kuunza chimiro chesimbi kumashure kusvika padyo neyekutanga mamiriro.

Annealing kana kudzima inzira inoshanda yekudzosera kukanganisa kwekushambadzira muAustenitic Stainless STEL.

Maitiro aya akaipisa simbi kusvika pakati pe1060 ℃ uye 1120 ℃. Akambotsiurwa, pombi yesimbi isina kupisa, yakakurumidza kutonhora kusimbisa zviyo uye chimiro. Uku kuwedzerwa kunowanzoshandiswa muzvikamu zvakakwira zveindasitiri
