1. Qhov loj dua lub tank cia, lub thicker lub tank plastered yog qhov tshaj li lub tank. Quantitative thickness yog xam los ntawm theoretical calculation.
2. Raw khoom yam ntawm lub tank. Cov tshuab hluav taws xob muaj zog ntau heev yog thinner dua cov roj tso pa uas tsis yog xim hlau uas tsis muaj zog. Nws kuj muaj qee qhov kev xuab zeb corrosion thicknesses txhua txhua xyoo hauv qee yam kev mob.
3. Cia lub tank ceev khoom. Qhov ntau dua qhov ua haujlwm siab, qhov loj dua qhov thickness ntawm cog lub tank. Lub sijhawm ntawd, cov hlau cia tau txais ntau dua. Cov pa roj carbon monoxide uas tsis yog xim hlau txais tsawg dua lossis tsuas siv tau rau qhov atmospheric siab xwb.
4. Tank kub qhov tseem ceeb. Feem ntau, cov hlau cia cov hlau thiab lub qhov quav hlau raug xaiv ntawm qhov kub siab. Lub sijhawm ua haujlwm ntawm lub tank cia siab dua, cov ntaub ntawv npaj yuav tsum tiv taus kom sov, thiab lub thickness ntawm lub tank cia yog thicker dua li qub kub. Cov khoom tsis muaj xim hlau uas tsis yog xim hlau tau txais tsawg dua kub.
5. Corrosion yam ntawm cov ntaub ntawv loaded. Corrosive, muaj ib txwm ib qho tas li ntawm corrosion qhov tas li, lub thickness ntawm lub tank yuav tsum thickened.
6. Environmental conditions. Cov kais hlau cov hlau cia tau tuaj yeem ua rau qhov chaw tsis zoo thiab qhov ntuj tsim, xws li cov xim tsis muaj xim lossis xim tsis zoo.
7. Lwm yam. Raws li cov qauv thiab txheej txheem ntawm lub tank cia, cov neeg kho tshuab thauj khoom-kabmob feem ntau tseem yuav tsum tau los ua ib co thickened thiab ntxiv dag zog. Piv txwv li, ob lub hau ntawm kab rov tav taub yog cov thicker dua lub cev lub cev, vim lub taub hau yuav hloov thaum lub taub hau yog khoov.
