Puas yog qhov tseemceeb vim yog cov nta ntxiv rau cov kav dej txawv-molybdenum kav, suav nrog cov khoom raj, suav nrog cov khoom siv raj, nrog rau cov khoom siv crorm, nrog rau cov khoom siv boron, thiab tungsten. Cov kawm qib no muaj nyob rau 92-122, 23-24, thiab siab dua li ntau. Cov CSA cov hlau yog txawv, raws li P (T) 91. Nrog rau cov ntsiab lus chromium ntau dua, hlau yog cov tshuaj sib txawv ntau nyob hauv ntau yam kev siv. Yog li ntawd nws feem ntau hu rau kev pab tseem ceeb nrog kev saib xyuas zoo dua.
Forged flangesAlloy Steel F9 Xov Flanges yog 100% rov ua dua tshiab, qhov twg 50% ntawm cov hlau tshiab yog tsim kev siv cov khoom siv tshiab muag hlau siv nws cov khoom siv eco. Muaj cov chav kawm sib txawv los qhia lub siab ntawm cov flanges. Cov li A182 F9 RTJ Flanges yog hom kev sib tw tshwj xeeb vim tias lawv tuaj nyob rau hauv ob ntu uas muaj ob lub nplhaib uas muaj ob kab ntawv uas tau coj mus ua ke los ntawm vuam.
Tus mlom
Lub vuam caj dab flanges muaj nyob thoob plaws cov ntaub ntawv. Cov ntaub ntawv no yuav tau ua raws li cov qauv txheej txheem. Cov ntaub ntawv tseem yuav tsum yog ib qho zoo ntawm ASTM lossis ASME cov qauv.ASME SA335 Qib P91 Yeeb NkabPeb muab F9 Alloy Steel Flanges uas muaj Superor corrosion tsis kam thiab ductility vim yog tus nqi me me ntawm chromium thiab molybdenum. A182 F9 Alloy Alloy Steel Flanges yog rau siv hauv qhov loj me thiab cov twj siab piping tshuab. Vim yog cov nqi me me ntawm chromium thiab molybdenum nws muaj superior corrosion tsis kam thiab ductility.
Tus mlom
Lub Flange Txuas hom feem ntau yog los nrog ob chav nyob, nrog gasket thiab qee qhov bolts & ceev txuas sib txuas. (Cov kav dej ua ntej yog welded ntawm cov flanges, tom qab ntawd li qub thiab lwm yam khoom siv tuaj yeem ntsia tau ntawm cov flanges.)
Tus mlom
Qib P91 yog muaj zog dua nws cov neeg ua ntej, T22 lossis P22 lossis P22 lossis P22 lossis tuaj yeem tiv taus kub txog li 600 ° C. Cov tuam txhab tsim khoom tuaj yeem nce cov ntsuas kub ua haujlwm rau qib ntau dua, nce qib kev ua haujlwm thiab ua rau muaj kev qaug zog qaug zog lub neej uas yuav luag kaum zaus siab dua. Ib qho ntxiv, thowner ntsiab tau tsim txij li cov kev txwv kub oxidation yog siab dua. Alloy P91 yeeb nkab feem ntau tso cai tsawg kawg 2-rau-1 txo qis hauv phab ntsa thickness. Ib lub phab ntsa thinner siv cov chaw muab tub lim hlau tsawg dua, lub sijhawm vuam muag, thiab cov khau khiab ntau. Cov txiaj ntsig zoo no tau ua tau los ntawm cov hlau lub siab chromium concentration. Qib 91 muaj 9% chromium thiab 1% molybdenum, thaum tus qib P22 tom ntej muaj 2.5% chromium.
