Cov kav hlau loj-txheej yas-coated steel kav yog tsim los ntawm cov kav hlau kav hlau lossis cov kav dej seamless steel raws li cov khoom siv hauv paus. Nws tsis pom zoo kom siv cov kav dej ncaj nraim welded. Ncaj-seam welded kav feem ntau tsis zoo li kauv steel kav nyob rau hauv cov nqe lus ntawm siab bearing, thiab tus nqi yog siab dua li ntawm kauv steel kav. Yog li ntawd, cov kav dej loj-txheej yas-coated steel kav tau pom zoo kom siv cov kav hlau kav hlau ua cov khoom siv hauv paus, thiab cov kav dej seamless steel siv thaum qhov kev thov siab dua.

Cov cheeb tsam tseem ceeb ntawm cov kav dej loj-txheej yas-coated steel kav yog muab faib rau hauv HVAC, nroog, kev lag luam, dej phwj tuaj, thiab lwm yam. Hauv thaj chaw ntawm HVAC thiab hauv nroog, cov kav dej loj-txheej yas-coated steel kav daws cov teeb meem ntawm xeb yooj yim, yooj yim scaling, thiab yooj yim muaj kuab paug ntawm cov kav hlau zoo tib yam. Tsis tas li ntawd, kev pabcuam lub neej ntawm cov kav dej loj-txheej yas-coated steel kav yog 5-10 npaug ntev dua li cov kav hlau ib txwm, uas txo cov nqi ntawm kev teeb tsa ua ntej thiab cov kav dej ua ntej faus, tus nqi ntawm kev kho tom qab, thiab tus nqi ntawm reinstallation thiab hloov tom qab lub neej kev pab cuam mus txog.

Hauv kev lag luam thiab cov dej phwj tuaj, cov khoom feem ntau tawm thiab thauj mus los muaj qee qhov pH nqi. Raws li cov txiaj ntsig ntawm oxidation mus sij hawm ntev, tus nqi corrosion ntawm cov kav hlau zoo tib yam yog kaum ob zaug sai dua li qhov qub. Tus nqi ntawm cov kav hlau loj loj yog siab heev, thiab kev xeb sai ua rau tus nqi nce siab. Qhov kev xav tau tsis tuaj yeem ua tiav, thiab daim duab loj poob rau qhov me. Kev siv cov kav dej loj-txheej yas-coated steel kav tsis txo qhov siab ntawm cov yeeb nkab nws tus kheej, thiab corrosion ntawm cov yeeb nkab hauv pH thiab ntev oxidation nyob rau hauv cov huab cua yog txo kom zero.

Yog li ntawd, kev pab cuam lub neej ntawm cov yeeb nkab yog nce los ntawm ob peb xyoos mus rau kaum xyoo. Lub neej kev pabcuam tau nce kaum npaug, tab sis tus nqi yuav luag tib yam.

Loj-inch yas-coated steel kav tau yeej qhov kev nyiam ntawm feem ntau ntawm cov neeg siv hauv HVAC, nroog, kev lag luam, dej phwj tuaj, thiab lwm yam kev lag luam nrog kev ua tau zoo, kev ua haujlwm siab, txuag hluav taws xob thiab kev tiv thaiv ib puag ncig, tu, thiab kev nyab xeeb.
