316L stainless hlau tau txais kev pom zoo thoob plaws hauv kev lag luam tshuaj thiab dej-kho kev lag luam vim muaj qhov sib npaug ntawm kev tiv thaiv corrosion thiab kev tsim cov nqi tsim khoom. Thaum xub thawj tsim rau cov kev pabcuam aqueous huv si, cov hlau no feem ntau siv rau hauv cov voj voog ncig uas nqa cov khoom raug tshem tawm zoo, suav nrog cov dej khib nyiab ua ntej kev kho mob, cov txheej txheem dej ntxhia nplua nuj thiab agitated batch reacted tanks. Ntau tus tsim cov cuab yeej siv tsuas yog ntsuas cov kua dej ntshiab huv, tsis quav ntsej txog kev sib xyaw ua ke-corrosion txaus ntshai uas tshwm sim los ntawm cov kua dej ob-theem ntws, uas ua rau lub neej ua haujlwm luv luv.
Erosion-corrosion yog ib hom kev puas tsuaj uas tsis yog qhov yooj yim superposition ntawm txhua yam hnav thiab electrochemical corrosion. High-speed ntws cov khoom tsis tu ncua cuam tshuam cov hlau nto, tshem tawm ib feem ntawm chromium-nplua nuj passive zaj duab xis hauv zos. Cov khoom siv hlau tshiab yog tom qab ntawd raug rau cov txheej txheem corrosive kua. Cov zaj duab xis passive tshiab yuav rov tsim dua, tab sis rov ua dua qhov cuam tshuam ua rau rhuav tshem cov txheej txheem tiv thaiv. Cov txheej txheem cyclic hnav-repassivation no ua kom ceev cov ntaub ntawv tshem tawm kom deb dhau ntawm tus kheej cov txheej txheem. Kev puas tsuaj yog tsom rau ntawm qhov chaw ntws-ntsej muag ntawm cov cua sov sheath, tsim cov grooved nto morphology.
Ntawm qhov chaw tsim khoom, qhov kev tsis ua haujlwm no tshwm sim hauv kev sib xyaw tso tsheb hlau luam, cov kav dej ntws siab thiab cov tshuab ntxhua khaub ncaws ntxhia. Cov neeg khiav dej num feem ntau saib maj mam ua kom sov lub zog poob thiab qhov tsis sib xws ntawm qhov chaw puas. Cov tsos mob zoo li no tau yooj yim ntaus nqi rau ib txwm siv tshuab. Txij li thaum cov ntaub ntawv poob tsim hauv zos, txo phab ntsa-thickness tuaj yeem ua sai sai yam tsis muaj qhov pom tseeb xeb. Thaum cov phab ntsa seem seem poob qis dua qhov kev nyab xeeb, cov dej xau tawm thiab ua rau cov khoom tsis tau npaj tseg.
Muaj ntau qhov kev siv tshuab ua haujlwm kom txo tau kev yaig-corrosion. Optimize pipeline layout thiab baffle tsim kom txo tau ncaj qha particle cuam tshuam tshaj tawm tiv thaiv lub rhaub nto. Tsim nyog nce sheath phab ntsa thickness rau ob-theem khiav kev pab cuam. Tswj cov khoom particle concentration los ntawm cov dej ntws tawm. Ua raws li kev ntsuas ultrasonic thickness tsis tu ncua tsom rau thaj chaw txaus ntshai.
| Cua sov hom | Erosion-Corrosion Risk nyob rau hauv Particle-Bearing Flow | Core Degradation Mechanism | Early-stage Diagnostic Feature | Qhov Tseem Ceeb Mitigation Engineering Measure |
|---|---|---|---|---|
| 316L Stainless hlau | Siab | Cov khoom tsis tu ncua abrade tiv thaiv passive zaj duab xis; cyclic hnav-repassivation accelerates localized hlau dissolution | Streamlined nto grooving; localized phab ntsa-thickness thinning yam tsis muaj xeb loj heev | Kev ua kom zoo dua qub; tso zis filtration; tsom thickness soj ntsuam |
| Titanium | Nruab nrab | Hard particles ua rau txhua yam nto abrasion; passive zaj duab xis tseem muab kev tiv thaiv ib nrab tom qab kev cuam tshuam | Matte cuam tshuam-fab qhov chaw; me ntsis khoom poob | Flow ceev txwv; periodic deg mob xyuas |
| Fused Quartz | Siab | Particle cuam tshuam tsim micro-scratches; khawb los ua kev ntxhov siab qhov chaw rau thermal tawg | Fine uniform nto hazy abrasion nyob rau hauv kev pom kev pom | Txo ntws impingement; solid-removal filtration |
| PFA-Jacketed | Nruab nrab-siab | Cov khoom tawv tawv tsim cov txheej txheem polymer nto scuffing, maj mam thinning tsho tiv thaiv txheej | Local gloss disappearance thiab faint nto qhab nia | Tsis txhob ncaj jet impingement; tsis tu ncua pom qhov chaw soj ntsuam |
Los xaus, kev sib tsoo-corrosion kev sib koom ua ke hnyav txwv 316L kev pabcuam lub neej nyob rau hauv cov kua dej ob-theem ntws. Laboratory corrosion cov ntaub ntawv los ntawm cov tshuaj tsis muaj particle tsis tuaj yeem cuam tshuam kev ua haujlwm tiag tiag hauv ntiaj teb. Flow qauv optimization thiab cov khoom tiv thaiv kab mob yog indispensable tiv thaiv kev ntsuas.
