Alloy 600 yog tsis muaj kev sib nqus, muaj cov tshuab ua ke zoo heev thiab ua ke ntawm lub zog siab thiab ua haujlwm zoo thiab muaj kev sib tw zoo thiab muaj kev sib tw zoo.

Monel K-500 sib txuas ua ke ntawm kev tiv thaiv corrosion zoo tshaj plaws ntawm monel 400 nrog cov txiaj ntsig ntxiv ntawm siab dua lub zog thiab Hardness. Kev ua tau zoo tuaj yeem txhim kho los ntawm kev ntxiv txhuas thiab titanium rau cov neeg muaj kuab lom thiab los ntawm kev tswj hwm ntawm cov neeg lom zem ntawm NI 3 (ti, al).

Kev nthuav dav zoo li qhov no tau ntsib cov kev kho mob thaum muaj cua sov uas tau txuas nrog lorication.

Alloy 347 (Unsen S34700) yog columbium stabilized ustenitic steelion steelion tsis kam thiab qee qhov zoo dua nyob rau hauv cov mob oxidizing zoo tshaj 321 (unc unical S32100).

Lub alloy 800 series (Incoloy 800, 800H thiab 800HT) yog siv tshuaj lom neeg lub zog ntawm Nickidation, carburization thiab lwm hom kev mob siab corrosion. Alloy 800 (tsis yog N08800), Alloy 800h (tsis yog N08810) thiab Alloy 800HT (0.85 rau 1.2%) kom paub meej cov kev ua tau zoo tshaj plaws.

Inconel 718 muaj cov npe menyuam yaus (52%). Alloy cov ntsiab suav nrog hlau (19%), chromium (18%), molybdenum (0.9%), molybdenum (0.9%), Cobalt, Tooj, Manganese thiab silicon.

Pipelines rau kev sib sau ua ke sour roj tau ua tiav nrog cov khoom (lossis clad) inconel? 625 alloy thiab siv nyob rau hauv dej hiav txwv sib pauv hluav taws xob hauv kev ua kom huv, cov nroj tsuag hluav taws xob, thiab offshore cov kev pab cuam sab saum toj uas feem ntau xav tau cov khoom no.

Lub hnub nyoog sluggish hnub nyoog-hardening teb ntawm alloy 718 tso cai annealing thiab vuam yam tsis muaj tseeb thaum cua sov thiab cua txias.

cov neeg siv khoom siv tau. Peb kuj tseem tuaj yeem muab tshem tawm tau tso ua haujlwm tso ua haujlwm, suav nrog cov qauv ntawm cov raj xa dej txiav, bevelling, sib dhos thiab

Txog kev pab cuam uas yuav tsum tau siv tau zoo tshaj plaws thiab tawg khoom, incoloy 800h lossis 800 ht siv. Cov ntsiab lus siab ntawm npib tsib xee thiab chromium hauv cov alloys kuj muab cov tshuaj tiv thaiv corrosion.

625 Yuav luag yuav luag tiav txoj kev ywj pheej los ntawm chloride induced kev ntxhov siab corrosion.

Yog li no, kev txhim kho ntawm cov npleem-ntawm cov flanges yog qhov yooj yim dua. Txawm li cas los xij, lub zog ntawm cov flanges-ntawm flanges yog ob-feem peb ntawm weld necked flanges, hauv qab kev ntxhov siab vim ntws. Lwm qhov tsis zoo ntawm cov npleem-ntawm flanges yog tias nws tsis yooj yim sua kom txhim kho lub lauj tshib lossis kho lub ntsej muag zoo nkauj rau lub ntsej muag zoo kawg nkaus ntawm cov fittings tsis ncaj. Qhov thib peb flange pab pawg yog lub qhov (socket) weld flanges. Cov flanges no tau siv rau cov kav dej me uas yuav tsum tau cog lus siab. Lub zog ntawm lub qhov (socket) weld flanges tawm tsam kev ntxhov siab sab hauv yog sib npaug ntawm cov flanges.

Al6xn muaj ntau dua tensile muaj zog tshaj li cov neeg tsis muaj qhov sib txawv, thaum khaws cov nqi siab dua thiab cuam tshuam lub zog.

Txawm li cas los xij, lawv txoj kev nkees nkees yog siab dua li cov flanges. Qhov teeb meem loj ntawm lub qhov (socket) weld flanges yog kev pheej hmoo corrosion. Ib qho sib txawv ntawm flange thiab haum lossis cov yeeb nkab yuav tsum tau tswj ua ntej vuam. Corrosive kua los yog av noo tuaj yeem nrhiav hauv cov chaw no. Yog li, cov kua-khov kho no yuav ua rau lub cev xeb ntawm lub cev.

Hastelloy B2 tiv thaiv kev tsim ntawm cov qoob loo ciam teb carbide precipitates nyob rau hauv lub weld cua sov cuam tshuam rau thaj chaw kev siv tshuaj nyob rau hauv cov txheej txheem kev siv tshuaj lom neeg. Cov cua sov cuam tshuam weld cheeb tsam txo cov nag lossis daus ntawm carbides thiab lwm yam theem kom ntseeg tau corrosion tsis kam.

Monel 400 cov tshuaj alloy tuaj yeem ua haujlwm txias los ntawm kev ua haujlwm txias, tab sis tuaj yeem ua haujlwm txias lossis ua haujlwm txias rau hauv cov txheej txheem vuam uas tsim nyog.

Raws li pib ntawm kev tsim khoom, txhua yam yuav tsum tau cim txhawm rau kom nce cov tshuaj ntawm cov ntaub ntawv. Cov kev ua haujlwm khij cov haujlwm tuaj yeem siv vim muaj tus naj npawb ntawm cov khoom siv. Ntxiv mus, txhua qhov ntev ntawm cov kav dej cov kab nyias yuav tsum tau cim rau lawv tus kheej. Cov kab ntawv ntawm cov cheebtsam yuav tsum tsis txhob paug cov khoom siv tuaj yeem ua rau cov khoom muaj thiab qhov no yuav ua rau muaj teeb meem loj.

Lub stainless hlau fab sib txaws cov spool yog pab rau cov neeg siv khoom uas lawv tsis nco qab ib feem twg thiab lawv tshem tawm cov teeb meem ntawm cov khoom seem.

Alloy B-2 muaj kev ua tsis zoo rau oxidizing ib puag ncig, yog li nws tsis pom zoo rau kev siv hlau lossis tooj liab, uas yuav ua rau muaj kev ua tsis tiav.

Hastelloy yog ib lub corrosion-resistant nickel alloy uas muaj lwm yam tshuaj lom neeg xws li chromium thiab molybdenum. Cov khoom siv no muaj qhov kub siab ua rau muaj kev kub ntxhov thiab zoo heev corrosion. Hastelloy C276 yog ib qib Hastelloy siv rau hauv cov roj thiab roj kev lag luam.
