Dab tsi yog ASTM A182 F316 khoom?

Stm A182 F316 tsim cov qib ntawm Austenitic Stainless hlau tsim, cov qauv siv hluav taws xob sib xyaw ua ke, thiab lwm yam khoom siv hluav taws xob, thiab cov ferless fittings, thiab li qub thiab seem rau Kev pab kub-kub-kub), F316 muaj npe rau nws cov kev ua kom zoo dua, siab siv cov kev siv muaj kev lag luam hauv kev lag luam inventions {8}

A182 F316 specification:

ASTM A182: Qhov no yog cov txheej txheem overarching uas piav txog cov kev cai tshuaj lom neeg lub zog.}}}}}}}} Kuv yeej ua kom cov khoom siv kub ua kom zoo sib xws thiab muaj kev ntseeg siab .

F316: Tus qauv ua ntej qhia tias nws yog ib qho kev txiav txim siab tsis pub dhau ntawm A182 qhov kev tsim qauv) molybdenum .

Cov yam ntxwv tseem ceeb ntawm Astm A182 F316:

• Txhim kho corrosion resistance: kev txhais cov ntsiab lus ntawm F316 (thiab nws cov countrepart, 316) yog qhov sib ntxiv ntawm {{3 Qhov no txhim kho kom tiv taus:

1. Pitting thiab crevice corrosion: tseem ceeb nyob rau hauv ib puag ncig muaj chlorides (zoo li dej hiav txwv, ntsev-ris cov txheej txheem dej, tshuaj lom neeg ntws).
2. General corrosion: tshwj xeeb hauv acidic ib puag ncig zoo li sulfuric ib puag ncig zoo li sulfuric, acetic, formic, thiab tartaric acids {}}
3. Nws muaj zoo dua tag nrho cov corrosion tsis kam piv rau F304 / F304L cov qib.

• Kev siv kub siab: tswj lub zog zoo thiab oxidation tiv thaiv nyob rau ntawm cov chaw thov kub siab nyob hauv nws cov kev txwv kub thiab txias.
• Formancion & Weldability: Zoo li lwm cov roj av tsis muaj zog, F316 qhov kev ua kom zoo nkauj thiab kev tawm tsam zoo li ASME Seem IX.
• Tsis muaj sib nqus: nyob rau hauv anealed mob, nws yog qhov tseem ceeb tsis muaj hlau nplaum.}} ua rau qee qhov kev teb txias {}}
• Toughness: Tswj kom zoo toughness thiab ductility nqes rau cryogenic kub .

Tshuaj lom neeg cov tshuaj:

Cov Khoom Siv Neeg Kho Tshuab:

NCO TSEG: Cov nqi tsawg kawg yog nyob ntawm daim ntawv thiab loj; Xa mus rau ASTM A182 rau tag nrho cov ntsiab lus .} Qhov kev cia siab thiab qhov kev cia siab ib txwm yog.

Cov kev siv cov kev siv ntawm ASTM A182 F316:

1. Tshuaj lom neeg & petrochemical ua: reactors, vessels tshav kub ua kom huv si thiab acids .
2. Roj & Roj Refining: Downhole cov cuab yeej siv, fittings, flanges nthuav tawm cov kev pab cuam muaj txiaj ntsig rau kev txwv tsis pub dhau los ntawm kev txwv tsis pub dhau los ntawm kev txwv
3. Kws Tshuaj & Khoom Noj Ua Si: Cov khoom siv tu qoob loo
4. Tubrogrog & Ntug dej: cov twj, cov roj, cov fittings, fasteners, fasteners, ceev ceev}
5. Lub Zog Hluav Taws Xob: Boiler Dej Thaib teb, Condenser Tubes, Flanges nyob rau hauv tsis-siab-kub ntu.
6. Pulp & Daim Ntawv Kev Lag Luam: Cov khoom siv tshuaj ua kom dawb huv, zom, piping .
7. Dej tshuaj: Desalination Nroj Tsuag, Kho Kom Kho Kom Qhuav In0.

F316 vs . F316L:

• F316: Qib qib nrog Max 0 {.}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} muaj ntau dua qhov kub tshaj F316L.
• F316L: Qhov "l" txhais tau tias tsawg carbon (Max 0 {} Qhov no} Qhov no} Qhov no muaj qhov tsis txaus ntseeg (ua rau mob corrosion tsis kam nyob rau hauv lub haz). F316L feem ntau nyiam rau:

1. Lub ntsuas hnyav ntawm Welded Cheebtsam .
2. Cov ntawv thov uas muaj feem cuam tshuam ntev li ntev ntev (kwv yees}}}℃f / 425℃{{} degree).
3. Kev tiv thaiv loj heev, tshwj xeeb tshaj yog xa peb .
4. Cov ntawv thov yuav tsum tau ua raws li txoj hlua khi ntawm txoj hlua khi cov qauv (NACE MR0175 / ISO 15156).

Vim li cas thiaj hais kom meej A182 F316?

Xaiv cov Cheebtsam tsim tawm rau ASTM A182 F316 muab kev ntsuas ntawm:

1. Khoom Siv Zoo: Cov khoom siv ua ke nruj thiab cov khoom yuav tsum tau ua tiav yog li cas .
2. Traceability: Cov ntaub ntawv xeem ntawv hauv MST / MST / ntawv pov thawj ntawm kev sib raug zoo) muab tag nrho traceeability .
3. Cov txheej txheem tswj: Kev txiav txim siab Forging kev coj ua thiab kev kho cua sov (tov annealing yog qhov yuav tsum tau) ua kom pom micrittration thiab khoom .
4. Kev Ua Haujlwm Kev Ntseeg Tau: muaj pov thawj kev ua tau zoo hauv kev yaum corrosive thiab kub-kub ib cheeb tsam.
5. Kev lees txais: Siv lub nkoj siab thiab cov piping ua siab loj xws li asme b31 (b31.3 (pawv roj boiler thiab siab vessel code (seem viii, div 1).
