Ib qho ntawm cov txiaj ntsig tseem ceeb tshaj plaws ntawm cov hlau carbon phaj kub dov yog lawv lub peev xwm los tiv taus qhov kub siab, ua rau lawv haum rau cov ntawv thov uas muaj kev raug cua sov. Tsis tas li ntawd, lawv muab kev sib txuas zoo heev, ua rau cov txheej txheem tsim khoom yooj yim dua thiab ua haujlwm tau zoo.
Cov ntawv hlau dov txias, ntawm qhov tod tes, yog tsim los ntawm cov txheej txheem uas cuam tshuam nrog kev tshem tawm cov nplai thiab kev ua tiav ntxiv ntawmCov hlau kub dov carbon phajCov txheej txheem ntxiv no txhim kho qhov chaw tiav thiab muab qhov ntev raug, ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau kev zoo nkauj thiab kev raug. Cov ntawv hlau txias-kuav feem ntau siv rau hauv cov lag luam zoo xws li kev lag luam tsheb thiab khoom siv.
Thaum nws los txog rau cov hlau kub dov tshwj xeeb,s235jr s355jr cov hlau carbon me me kub dovyog qhov xav tau heev vim lawv cov khoom siv kho tshuab zoo heev. Cov ntawv no muaj lub zog zoo heev thiab qib siab ntawm kev tiv thaiv corrosion, ua rau lawv haum rau cov qauv siv hauv ntau yam lag luam. Tsis tas li ntawd, cov hlau kub dov zoo tshaj plaws lav qhov zoo tshaj plaws thiab kev ua haujlwm tas mus li, ua kom cov neeg siv khoom txaus siab thiab lub neej ntev.
s335 hlau kub dov phaj yog lwm qhov kev xaiv nrov, tshwj xeeb tshaj yog nyob rau hauv cov lag luam hnyav xws li kev tsim kho thiab kev tsim khoom. Paub txog lawv qhov ruaj khov thiab kev ntseeg tau, cov vaj huam sib luag no muaj lub zog thiab kev tawv tsis sib xws, ua rau lawv muaj nqis rau cov qauv thauj khoom thiab cov tshuab hnyav.

Hauv kev xaus lus, ob qho tib si cov hlau carbon steel phaj kub dov thiab cov hlau phaj txias dov muaj lawv tus kheej qhov zoo. Qhov qub qhov kev hloov pauv tau yooj yim, kev siv nyiaj tsim nyog thiab kev sib txuas ua rau nws yog qhov kev xaiv txhim khu kev qha rau ntau yam kev siv. Qhov kawg, ntawm qhov tod tes, muab qhov ua tiav zoo dua thiab qhov ntev thiab feem ntau yog thawj qhov kev xaiv hauv kev lag luam uas qhov zoo yog qhov tseem ceeb. Kev nkag siab txog qhov sib txawv ntawm ob hom hlau phaj no tuaj yeem pab kev lag luam ua qhov kev xaiv zoo raws li lawv cov kev xav tau tshwj xeeb thiab cov txiaj ntsig kawg xav tau. Txawm hais tias nws yog hlau phaj kub dov lossis hlau phaj txias dov, cov neeg muab khoom hlau txhim khu kev qha tuaj yeem muab cov kev xaiv zoo los ua kom tau raws li qhov xav tau ntawm txhua qhov kev lag luam.
