ASTM A285 / A285M specification npog qis rau nruab nrab tensile lub zog carbon steel daim hlau uas tuaj yeem ua los ntawm cov kua qaub-tua, semi-dig muag, coated, lossis flange steel. Cov phaj no yog tsim los rau welded siab hlab ntsha. Cov ntawv feem ntau yog muab dov. Cov hlau yuav tsum ua kom tau raws li qhov xav tau ntawm cov tshuaj muaj pes tsawg leeg. Cov phaj xa tuaj raws li cov qauv ntsuas tensile yuav tsum ua tau raws li cov cuab yeej cuab yeej cuab tam. Txuj hauv paus steel qib ASTM A285 / A285M: ASTM A285 Qib A, B, C (A285GRA, B, C).

Dab tsi yog steel phaj rau cov hlab ntsha siab?
Pressure Vessel Steel Phaj npog ntau yam ntawm cov qib steel uas yog tsim los siv rau hauv cov hlab ntsha siab, boilers, kub exchangers thiab lwm lub nkoj uas muaj roj los yog kua. Cov piv txwv paub muaj xws li cov thooj av roj rau kev ua noj thiab vuam, lub tog raj kheej oxygen rau kev dhia dej, thiab ntau lub tank hlau loj uas koj pom nyob rau hauv cov roj refinery lossis cov nroj tsuag tshuaj. Muaj ntau ntau yam tshuaj sib txawv thiab cov kua dej uas khaws cia thiab ua tiav raws li qhov siab. Lawv txawv los ntawm cov khoom tsis zoo xws li mis nyuj thiab xibtes roj, rau cov roj av thiab cov nkev thiab lawv cov distillates, mus rau cov kua qaub thiab tshuaj lom neeg xws li methyl isocyanate. Yog li, cov txheej txheem no xav kom cov roj los yog kua ua kom kub heev, thaum lwm tus ua kom lawv nyob rau qhov kub thiab txias. Raws li qhov tshwm sim, muaj ntau yam sib txawv ntawm qib siab ntawm cov hlab ntsha steel muaj kom haum rau ntau yam kev siv.
