Cov ob chav hlau laj kab muaj cov txheej txheem yooj yim, cov khoom siv tsawg, cov nqi ua haujlwm tsawg, thiab yooj yim rau kev thauj mus los ntev, yog li tus nqi tsim nyog tsawg; hauv qab ntawm lub laj kab thiab cov phab ntsa cib-pob zeb yog ua los ntawm tag nrho, uas zoo kov yeej qhov tsis muaj rigidity ntawm lub vas thiab txhim kho kev tiv thaiv kev ua haujlwm. Tam sim no nws tau txais dav los ntawm cov neeg siv khoom nrog cov ntim loj. Hais txog lub rusty tsos ntawm ob sab hlau laj kab, lub ntsiab yog vim li cas yog hais tias cov tsos tau ua ib tug loj theem ntawm corrosion, xws li baffle, stud txav, los yog lwm yam thiab qhov tseem ceeb ntawm kev siv lub system.
Tsawg-hydrogen electrode yog siv rau monotonous thiab tshem tawm cov roj thiab xeb ntawm qhov chaw vuam, preheating ua ntej vuam thiab kev kho cua sov tom qab vuam. Yuav ua li cas nws thiaj li qeeb qeeb xeb, tiv thaiv xeb, thiab ua kom ntev kev pab cuam lub neej. Raws li cov ntaub ntawv raw, txhawm rau siv ob sab ntawm lub laj kab hlau, xaiv cov ntaub ntawv siv ntau dua, thiab tom qab ntawd mus los ntawm kev tiv thaiv corrosion xws li txheej txheej, dipping, thiab kub-dip galvanizing.
Cov khoom no muaj ntau dua nyob rau hauv tsos, ntev nyob rau hauv kev siv, thiab ntau dua nyob rau hauv kev siv. Cement cua: Vim tias cov pa cement yog ib qho nyuaj, peb xaiv cov khoom siv drilling, tseem hu ua cov khoom siv hauv av, uas yog welded flange nyob rau hauv qab ntawm kem, laum qhov rau hauv av, thiab ces ncaj qha siv cov expansion screws rau laum lub qhov. Cov hom ntawv muaj feem cuam tshuam nrog kev sib tsoo, yog li tsawg tus neeg xaiv.
