ASTM A533 Boiler steel phaj Cov lus piav qhia
ASTM A533 boiler nkoj phaj yog manganese-molybdenum thiab manganese-molybdenum-nickel alloy steel phaj haum rau siv nyob rau hauv welded siab hlab ntsha.ASTM A533 boiler nkoj steel muaj nyob rau hauv tsib qib sib txawv zog: Class A, B, C, D, thiab E . Cov hlau muaj nyob rau hauv peb qib: Qib 1, 2, thiab 3. Txhua chav kawm muaj peb qib ntxiv: Chav Kawm 1, Chav Kawm 2, thiab Chav Kawm 3. Txhua ASTM A533 boiler nkoj phaj muaj qhov tuab yam tsawg kawg nkaus ntawm 0 .25 nti, los yog 6.5mm.
Lub thickness ntawm sab sauv txwv rau Chav Kawm 1 thiab Chav Kawm 2 ASTM A533 boiler nkoj phaj tsuas yog txwv los ntawm lub peev xwm ntawm cov tshuaj muaj pes tsawg leeg kom tau raws li cov kev cai ntawm cov cuab yeej cuab tam. Txawm li cas los xij, tam sim no feem ntau txwv qhov tuab ntawm Chav Kawm A / B / C / D ASTM A533 boiler phaj rau 12 ntiv tes, piv txwv li, 300 hli, thiab txwv cov thickness ntawm Class E ASTM A533 boiler phaj rau 7 ntiv tes, piv txwv li, 180 mm.
Rau Chav Kawm 3 ASTM A533 boiler phaj, qhov siab tshaj plaws ntawm Chav Kawm A / B / C / D phaj yog 2.5 ntiv tes, lossis 65 hli, thiab cov tuab ntawm Chav Kawm E phaj yog txog 2 ntiv tes, lossis 50 hli.
ASTM A533 boiler nkoj phaj muaj qhov zoo heev uas tsis tshua muaj kev kub ntxhov thiab cov khoom siv kho tshuab, feem ntau yog siv rau hauv qhov kub thiab txias.ASTM A533 boiler nkoj phaj yog dav siv nyob rau hauv qis kub sib cais thiab ua, liquefied gas cia thiab lwm yam teb, xws li loj. -scale nqus tsev vacuum low-temperature liquefied natural gas (LNG) cia khoom. Lub caij no, ASTM A533 boiler nkoj phaj feem ntau yog siv nyob rau hauv thaj tsam banded ntawm nuclear reactor hlab ntsha, qhov twg cov khoom siv yuav cuam tshuam los ntawm cov hluav taws xob muaj zog.
