Dab tsi yog Pressure Vessel Steel Phaj?
Lub nkoj siab steel phaj npog ntau yam ntawm cov qib steel uas yog tsim los siv rau hauv cov hlab ntsha siab, boilers, hloov hluav taws xob thiab lwm yam hlab ntsha uas muaj cov roj los yog kua ntawm lub siab. Cov piv txwv paub muaj xws li lub tog raj kheej roj rau kev ua noj thiab rau vuam, lub tog raj kheej oxygen rau kev dhia dej thiab ntau lub tank loj loj uas koj pom hauv cov roj refinery lossis cov nroj tsuag tshuaj. Muaj ntau ntau yam tshuaj sib txawv thiab cov kua uas khaws cia thiab ua tiav raws li qhov siab. Cov no muaj xws li benign tshuaj xws li mis nyuj thiab xibtes roj rau cov roj crude thiab natural gas thiab lawv distillates rau cov acids thiab tshuaj lom neeg xws li methyl isocyanate. Yog li ntawm cov txheej txheem no xav tau cov roj los yog kua ua kom kub heev, thaum lwm tus muaj qhov kub thiab txias. Raws li qhov tshwm sim muaj ntau yam sib txawv ntawm cov hlab ntsha steel qib uas ua tau raws li qhov sib txawv siv.
Feem ntau cov no tuaj yeem muab faib ua peb pawg. Muaj ib pab pawg ntawm carbon steel siab hlab ntsha qib. Cov no yog cov qauv steels thiab tuaj yeem tiv nrog ntau daim ntawv thov uas tsis tshua muaj corrosion thiab tsis tshua muaj cua sov. Raws li cov cua sov thiab corrosion muaj qhov cuam tshuam ntau dua ntawm cov hlau phaj chromium, molybdenum thiab npib tsib xee ntxiv los muab kev tiv thaiv ntxiv. Thaum kawg raws li cov% ntawm chromium, npib tsib xee thiab molybdenum nce koj muaj cov hlau tsis muaj zog tiv taus cov hlau uas siv rau hauv cov ntawv thov tseem ceeb thiab qhov twg oxide yuav tsum tau zam - xws li hauv cov khoom noj thiab tshuaj lag luam.
