S32205 yog lub duplex stainless hlau nrog ob zaug lub zog ntawm Anustenitic Stainless hlau. Duplex stainless hlau muaj txog 21% chromium, 2.5% molybdenum thiab 4.5% npib tsib xee-nitrogen alloy. Nws muaj lub zog siab, cuam tshuam zoo heev nruj thiab zoo tag nrho thiab kev ntxhov siab hauv cheeb tsam kev tiv thaiv. Cov txiaj ntsig lub zog ntawm ob lub stlexs stainless hlau yog ob zaug uas ntawm Austenitic stainless hlau, ib qho kev tsim tawm thaum tsim cov khoom lag luam, ua rau cov khoom lag luam uas muaj peev xwm ua rau muaj 316, 317l. Cov alloy no yog tsim nyog rau kev siv nyob rau hauv cov -50¡ÃF \ / + 600¡Ãf kub. Rau cov ntawv thov sab nraum qhov kub thiab txias no, tab sis muaj qee qhov kev txwv, tshwj xeeb tshaj yog thaum siv rau welded qauv. Duplex Stainless hlau muaj ob zaug lub compressive lub zog piv rau antenitic stainless hlau, thiab cov tsim qauv tuaj yeem txo nws qhov hnyav piv rau 316L thiab 317L. Alloy 2205 yog qhov tshwj xeeb rau kev siv nyob rau hauv the -50¡ÃF \ / tseem siv tau ntawm qhov chaw kub qis dua nyob rau hauv kev txwv hnyav nyob rau hauv kev txwv hnyav (tshwj xeeb yog rau welded qauv).
Peb tus TI Qib 2 Flange, Carbon Steel A694 F60 F65 (TTM ARB, ASTM A182 S32750 Stad Bolt yog qhov tshiab hauv thev naus laus zis thiab tsim nyog hauv cov qauv. Lawv muag tau zoo nyob hauv tsev thiab txawv tebchaws thiab tau txais tos los ntawm cov neeg siv feem ntau. Los ntawm kev ua haujlwm zoo, peb vam tias yuav ua rau muaj kev loj hlob ua kom muaj kev loj hlob ntawm kev tswj hwm ib puag ncig thiab qhov tseem ceeb ntawm cov muaj zog tib neeg cov peev txheej. Tam sim no, peb tab tom siv zog ntxiv rau hauv qhov tshiab ib txwm, cia siab tsim kho tus qauv tshiab ntawm lub tuam txhab kev txhim kho hauv kev coj tshiab. Thaum nkag siab cov ntsiab lus tseem ceeb ntawm kev siv tshuab, lub tuam txhab them ntau dua los muab cov khoom lag luam thiab cov kev pabcuam zoo dua. Cov cuab yeej siv tau zoo heev, cov txuj ci kws tshaj lij, cov kev pab ntau lawm, kev lees paub zoo thiab raws sijhawm tau peb cov neeg siv khoom.
Lub corrosion resistance ntawm sa 335 P91 seamonless yeeb nkab yog ntau dua li cov tshuaj carbon. Qib P91 yog siv rau cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau alloy. Tus hlau chromium-molybdenum hlau, cov tshuaj lom neeg muaj kuab lom ntawm Astm A335 P91 Alloy Steel Yeeb muaj 9% chromium thiab 1% molybdenum thiab vanadium.
ASTM A193 Qib B7 yog cov khoom siv cov khoom siv chromium rau lub zog hlau-molybdenum rau siab, siab siv tau, thiab cov ntaub ntawv tshwj xeeb. Qib B7 yog ib qho cua sov kho chromium molybdenum yuav tsum tau ntawm 100 ksi, muaj zog tsawg kawg ntawm 75 ksi thiab lub siab kawg ntawm 35 hrc. Lub ATTM A193 Cov Kev Siv Tshwj Xeeb Tshwj Xeeb rau Tshuaj Muaj Tshuaj, Cov Khoom Siv Txhua Yam, Hardness, Kev Kho Mob Cua Sov, thiab Pom zoo Cov Txiv Ntseej rau Chav B7 Rasteners. ASTM A193 Qib B7 yog qhov nthuav dav rau kev tawm tswv yim rau cov fasteners, feem ntau pom nyob hauv bolts lossis kav dej, li qub, flanges thiab fittings.
Piv rau lwm cov txheej txheem tsim kev tsim khoom, ASTM A182 F22 Kev Forging Mas Horging yog tsom rau kev ua tau ntawm cov khoom muaj zog tshaj plaws. Nws tsis yog tsuas yog txwv rau cov hlau thiab cov hlau forging tab sis thiab nrog rau lwm cov hlau kuj.
Cov khoom siv tuaj yeem yog cov cua sov kho rau anneal thiab normalize hauv huab cua, lossis quench thiab temper hauv polymer lossis roj. Alloy 4130 muaj cov ntsiab lus txo cov ntsiab lus ntawm 0.28% - 0.33% thiab me ntsis siab dua ntawm lwm cov khoom. Thiab cov khoom siv tau yooj yim rau cov txheej txheem. 4140 Tsawg Alloy Steel muaj ntau ntawm 2. 375 "txog 12.750" Od nrog cov phab ntsa thicknesses txij li 0.375 "rau 1.5". Alloy 4145 muaj cov ntsiab lus muaj roj carbon ntau dua li 4140 thiab 4130 hom cov kav dej.
ASTM A335 Qib P11 tseem yog cov npe hu ua ASME Sa335 Qib Pipes, nws yog ib daim ntawv siv seamless ferritic alloy-steel hlau uas feem ntau muaj cov ntawv thov kub siab. Kev tsim qauv tsis ua haujlwm rau qib kawm no P11 yog K11597.
