Kuv puas xav tau kev txhawj xeeb txog kev sib cais disimility corrosion yog tias kuv xaiv aGrooved Zas Hlau Coupling? Peb yuav piav qhia tau li cas dissimilarat corrosion tshwm sim thiab yog vim li cas xaiv aGrooved Neeg Kho Tshuab Yeeb KoomKev daws yog qhov zoo tagnrho rau koom nrog stainless hlau thiab tooj liab piping tshuab.
Lub zog, corrosion kuj, thiab tus nqi qis ntawm kev saib xyuas yog txhua qhov laj thawj uas cov kev pabcuam tshuab cov khoom lag luam. Tab sis yuav ua li cas yuav tsum cov hlau stainless tau koom ua ke? Thiab
Nyob rau hauv dissimilar hlau corrosion, qhov kev tawm tsam hnyav tshaj plaws tshwm sim ntawm cov hlau uas muaj qhov sib txawv ntau dua hauv cov txheeb ze. Piv txwv li, titanium thiab txhuas yuav muaj kev tawm tsam ntau dua lossis hnyav dua, nyob rau hauv ib qho xwm txheej tsis sib xws, tsis tooj liab thiab tooj dag. Qhov no yog vim qhov tseeb tias titanium thiab txhuas muaj qhov sib txawv ntau dua thaum sib piv tooj liab thiab tooj dag.
Dab tsi yog cov electrolyte raws li nws cuam tshuam rau hlau corrosion?
Txhawm rau kom nkag siab li cas thiab vim li cas "kev tawm tsam" tshwm sim ntawm kev sib cais me me, peb yuav saib cov dej ntws los ntawm ib hlau mus rau lwm tus.
Txhua cov hlau muaj cov feem cuam tshuam hluav taws xob. When metals of different electrical potentials are in contact in the presence of an electrolyte, a low energy electrical current flows from the anodic metal to the cathodic metal. Raws li tau hais dhau los, ntau cov hlau puab tsaig hlau yog cathodic; Cov hlau uas muaj cov noble yog anodic thiab muaj peev xwm ntau dua rau corode txheeb ze rau corrodic hlau uas nws muaj kev sib cuag nrog.
Kuv puas tuaj yeem siv cov grooved hlau txuas rau ntawm cov yeeb nkab steel?
Yog lawm, koj tuaj yeem siv cov hlau stainless couplings ntawm cov yeeb nkab stainless hlau; Txawm li cas los xij, nws yuav raug nqi thiab tsis tsim nyog rau qee cov ntawv thov. Qee qhov haujlwm yuav qhia kom meej cov raj hlau stainless hlau vim yog ib puag ncig sab nraud ib puag ncig cov pas dej piping. Thaum cov kua dej ua kua yog cais nrog kev sib cuag nrog cov tsev sib txuas los ntawm cov gasket, cov yeeb nkab yuav tsum tau tiv thaiv los ntawm cov dej sab nrauv.
Cov xwm txheej uas muaj cov dej nyab sab nrauv tuaj yeem tsim thiab qhov twg cov tsis sib xws tau sib chwv nrog:
- YEEB tawm hws
- faus cov ntawv thov
- Cov ntawv thov submerged
Ua tsaug rau koj saib.
