Thaum xaiv cov ntaub ntawv hlau cov nplais rau kom ntseeg tau tias cov kev xaiv Fibers ua tau raws li cov ntaub ntawv tshwj xeeb ntawm cov raj xa dej hauv ntau yam xwm txheej. Ua ntej, hom thiab loj ntawm cov hlau steel yog qhov tseem ceeb me ntsis los txiav txim siab thaum xaiv. Txawv ntau hom steel fibers sib txawv sib txawv ntawm cov kev cuam tshuam zoo, kev coj tsis zoo, yog li ntawd nws yog qhov tsim nyog los xaiv cov raj xa dej uas tsim nyog raws li cov kev xav tau. Qhov loj ntawm cov fibers ncaj qha cuam tshuam lawv cov xa tawm thiab cov khoom siv mechanical ntawm cov pob zeb ua. Ntev dua steel fibers tuaj yeem txhim kho cov khoom siv tensile lub zog thiab tawv, txhim kho lub raj xa hluav taws xob tsis kam thiab cuam tshuam tsis kam. Txawm li cas los xij, cov txiaj ntsig ntev kuj tseem nce cov khoom siv cov khoom siv ntev, yog qhov sib npaug yuav tsum tau ua ntawm kev txhim kho kev ua haujlwm thiab cov nqi tswj hwm.
Qhov txoj kab uas hla ntawm cov ntoo steel kuj tseem muaj kev cuam tshuam tseem ceeb ntawm cov raj xa dej ua haujlwm. Coarser steel fibers pab txhim kho lub zog compressive ntawm cov pob zeb ua, ua kom cov raj xa dej kom zoo dua nrog kev tawm sab nraud. Coarse cov fibers feem ntau yog siv nyob rau hauv cov xwm txheej nrog lub zog siab dua, tab sis qhov no kuj nce cov nqi khoom siv. Yog li ntawd, txoj kab uas hla yuav tsum tau xaiv raws li cov raj xa dej ua haujlwm siab, ib puag ncig cov kev mob, thiab tus nqi ua haujlwm zoo.
Corrosion tsis kam yog lwm qhov tseem ceeb ntawm kev xaiv cov hlau fibers rau pipelines. Cov kav dej feem ntau siv los thauj ntau yam kua dej, suav nrog cov khoom siv corrosive xws li cov roj av, thiab cov khoom lag luam ruaj khov ua haujlwm ntev. Stainless hlau fibers thiab alloy steel fibers feem ntau muaj kev tiv thaiv corrosion thiab oxidation tsis kam los ntawm xeb lossis xeb thaum lub sijhawm. Yog li ntawd, xaiv cov khoom haum corrosion-resistant cov ntaub ntawv tuaj yeem txhim kho cov raj xa dej thiab kev nyab xeeb.
Tsis tas li ntawd, cov txheej txheem ntau lawm ntawm cov khoom siv hlau thiab zoo ntawm cov ntaub ntawv raw yog qhov tseem ceeb rau kev ua tau zoo ntawm cov ntoo steel. Cov txheej txheem tsim cov txheej txheem txiav txim siab qhov kev sib xws thiab lub zog ntawm cov khoom siv tau ncaj qha cuam tshuam ncaj qha rau cov fibers. Thaum xaiv cov khoom siv hlau steel, nws yog qhov tseem ceeb kom ntseeg tau tias tus neeg xa khoom muab cov txheej txheem zoo uas ua kom paub tseeb tias cov txheej txheem steel ua tau kom tau raws li cov raj xa hluav taws xob tuaj yeem ntsib cov raj xa dej.
Hauv kev xaus, thaum xaiv cov raj hlau cov fibers rau cov kav dej, nws yog qhov tsim nyog los txiav txim siab, thiab kev xaiv tau zoo raws li cov kev thov tshwj xeeb. Los ntawm kev nkag siab cov ntsiab lus, nws yog qhov ua tau kom ntseeg tau tias cov khoom siv steel xaiv tau raws li kev ua tau zoo thaum xav tau cov khoom siv thiab txhim kho cov txiaj ntsig zoo.
