Cov khoom sib txuam yog li pib nrog cov txheej txheem chemistry es tsis yog cov ntawv teev npe dav dav. Rau kev pabcuam sulfuric nyob rau hauv ib puag ncig, tag nrho tua cov pa roj carbon steel qib xws li ASTM A516 Gr. 70 nrog rau kev tiv thaiv corrosion tseem nyob hauv kev lag luam, muab kev tsim qauv ua raws li kev tsim thiab tshuaj xyuas cov lus qhia ntawm NACE SP0294-2025. Thaum cov kua qaub poob, cov chlorides tshwm sim, lossis kub nce, 316L stainless (2-3% molybdenum) cov khoom siv ntau dua pitting tsis kam; Cov ntaub ntawv pov thawj acetic-acid tank kev tshawb fawb thiab cog PMI cov ntaub ntawv lees paub nws qhov zoo tshaj 304 qib. Qhov twg impurities los yog fluctuating concentrations ntxiv nqaim lub qhov rais muaj kev ruaj ntseg, duplex 2205 los yog Alloy 20 ncua lub stability ntau yam tsis tam sim ntawd invoking nickel{14}}alloy nqi. Hybrid txoj hauv kev-carbon-steel shells tiv thaiv los ntawm epoxy-novolac los yog roj hmab hauv ob sab phlu-muab qhov nruab nrab nqi-kev ua tau zoo tshuav nyiaj li cas thaum muaj kev soj ntsuam tas mus li.
Lub sijhawm ntev - kev ncaj ncees nyob ntawm ntau dua li kev xaiv alloy. Factory-passivated modular 316L kev tsim kho tshem tawm ntau qhov cua sov- thaj chaw cuam tshuam uas tom qab dhau los ua kev ntxhov siab- qhov chaw pib corrosion, ib qho taw qhia rov ua dua tshiab hauv seismic-cov nroj tsuag Asian nyiam ua rau API 650 lossis AWWA D103 cov hauv paus ntsiab lus. Kev tshawb fawb ultrasonic thickness tsis tu ncua thiab kev kuaj xyuas cov khoom zoo (PMI), teem caij raws li lub sijhawm soj ntsuam pom zoo hauv NACE SP0294-2025, kuaj xyuas cov phab ntsa thaum ntxov ua ntej kev tsim tawm. Kev tiv thaiv Cathodic ntawm qhov tsawg tam sim no tseem tau rov qab ua haujlwm hauv ntau lub Gulf Coast 316L cov hlab ntsha uas tau pib rau hauv qhov los ntawm inhibitor-derived chlorides.
Kev hloov kho qhov project ua raws li kev pom zoo. Concentrated-acid bulk tanks nyiam carbon-steel shells nrog tswj kev tiv thaiv corrosion thiab sab nraud galvanized lossis coated structural kev txhawb nqa; dilute los yog tov-acid lub luag hauj lwm hloov mus rau 316L los yog duplex hlab ntsha, feem ntau clad los yog lined. Thib ob thiab cov yeeb nkab-txhawb cov thav duab nyob ib puag ncig cov tso tsheb hlau luam no tau txais txiaj ntsig los ntawm kev pleev xim ua ntej lossis nano-coated galvanized kauj, uas tiv thaiv cov txaws thiab vapor thaum tseem tsim tau rau cov hlua thiab cov kev taug kev. Qhov no zoning mus kom ze, kos los ntawm cross-cov ntaub ntawv hauv cheeb tsam tshuaj xyuas, txo ob qho tib si qhov tshwm sim thiab tus nqi ntawm lub neej.
Rau cov khoom siv coil thiab cov ntawv uas haum rau lub plhaub tank, cov ntaub ntawv, thiab cov qauv kev txhawb nqa hauv cov kev pabcuam acid, tshuaj xyuas cov khoom muaj316 prepainted stainless hlau kauj, nano anti-corrosion rwb thaiv tsev board rau cov nroj tsuag muaj, thiabprepainted galvanized steel kauj. Muab cov kua qaub ntau, qhov kub thiab txias, thiab cov ntaub ntawv tsis huv kom tau txais daim ntawv pov thawj zeb thiab qhov project -cov lus pom zoo tshwj xeeb uas ua kom pom tseeb qhov tseem ceeb ntawm cov pa tawm -dawb, ntev - ua haujlwm ntev.
