Cov kav hlau steel ua lub luag haujlwm tseem ceeb ua cov khoom siv hauv cov haujlwm engineering. Tab sis kev siv lub neej ntawm cov yeeb nkab steel yuav raug cuam tshuam vim lawv qhov chaw ua haujlwm thiab kev ua haujlwm. Txhawm rau kom muaj kev ruaj ntseg engineer peev, peb xav kom txuas cov kav dej siv lub neej los ntawm cov hauv qab no,
a) Kev tiv thaiv corrosion
Cov kav hlau muaj qhov ua rau corrosion nyob rau hauv qhov chaw ntub thiab corrosive, yog li txo lawv lub neej kev pab. Kev siv los tiv thaiv kev tiv thaiv kev tiv thaiv tuaj yeem tiv thaiv corrosion thiab txuas ntxiv lub neej kev pab cuam ntawm cov kav hlau. Cov txheej txheem los tiv thaiv corrosion feem ntau suav nrog kev txau cov tshuaj tiv thaiv corrosion, kub-dipped galvanizing, 3LPE txheej, thiab lwm yam, thiab cov txheej txheem tiv thaiv corrosion tsim nyog raug xaiv raws li qhov chaw tshwj xeeb.

b) Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua
Kev tshuaj xyuas tsis tu ncua ntawm cov kav hlau steel, kev tshawb nrhiav raws sij hawm thiab tuav cov teeb meem muaj peev xwm, tuaj yeem tiv thaiv qhov teeb meem tsis zoo ntxiv. Kev soj ntsuam tsom xam suav nrog kev sib txuas ntawm cov kav dej, welds, corrosion kuj, thiab lwm yam. Thaum pom cov xwm txheej txawv txav, kev tswj xyuas raws sij hawm yuav tsum tau ua kom tswj tau qhov zoo ntawm cov yeeb nkab steel.
c) Tswj kev siv ib puag ncig
Kev siv ib puag ncig ntawm cov kav dej steel muaj qhov cuam tshuam tseem ceeb rau lawv lub neej. Kev zam kom tsis txhob cuam tshuam ntev rau qhov chaw corrosive xws li ya raws, kua qaub, thiab alkali tuaj yeem ua rau qeeb ntawm corrosion ntawm cov kav hlau thiab ua rau lawv lub neej ua haujlwm. Yog tias ua tau, kev ntsuas cais xws li siv cov txheej txheem tiv thaiv lossis cov ntaub ntawv rwb thaiv tsev yuav tsum tau coj los txo qhov cuam tshuam ntawm ib puag ncig sab nraud ntawm cov yeeb nkab steel.
d) Kev xaiv cov khoom siv
Thaum xaiv cov kav dej steel, xav txog kev siv ib puag ncig thiab cov kev xav tau, thiab xaiv cov khoom tsim nyog tuaj yeem cuam tshuam rau lub neej kev pabcuam ntawm cov kav hlau. Cov khoom sib txawv ntawm cov yeeb nkab steel muaj qhov sib txawv corrosion kuj thiab cov khoom siv kho tshuab, thiab xaiv cov khoom tsim nyog tuaj yeem txhim kho lub neej kev pab cuam ntawm cov yeeb nkab steel.
