Yog tias koj ua haujlwm nrog cov kav dej, cov li qub, twj, lossis cov hlab ntsha siab nyob rau hauv kev thov cov khoom lag luam thiab roj offshore roj & roj, koj yuav tau ntsib A182 F316. Qhov kev tsim qauv no tseem ceeb heev rau kev qhia txoj cai ntawm cov hlau uas muaj ntsaws rau kev ua kom haum thiab cov kev pabcuam siab. Tab sis dab tsi raws nraim li A182 F316 tus qauv entail? Cov lus qhia no piav qhia txog cov tseev kom tseem ceeb hauv cov ntsiab lus meej.
ASTM A182 F316.
ASTM A182 F316 yog cov ntaub ntawv tshwj xeeb tsim los ntawm Astm International. Nws txhais cov kev xav tau rau cov kev xav tau rau forged lossis rollated alloy thiab stainless hlau yeeb nkab flanges, forging fittings, li qub, thiab lwm yam kev siab siab. Lub "F316" ib feem tshwj xeeb yog hais txog cov lus zam txim tau los ntawm "316" qib ntawm Austenitic Stainless hlau. Qhov tseem ceeb, A182 F316 qhia cov tuam ntxhab puas yog dab tsi uas tau hais txog cov hom phiaj 316 stainless hlau yuav tsum tau ua kom haum rau qhov kev ua kom haum corrosion thiab lub zog yog qhov tseem ceeb.
A182 F316 Kev Siv Tshuaj
Lub corrosion tsis kam ntawm A182 F316 stems feem ntau los ntawm nws cov tshuaj pleev kom zoo pleev. Nyiam hom qauv 316 stainless hlau ntawv lossis phaj (them los ntawm A240), A182 F316 nyob ntawm peb lub ntsiab tseem ceeb:
- High Chromium (CR):Yam tsawg kawg 16. 0%. Chromium cov ntaub ntawv pom qhov pom, kev kho tus kheej kho cov roj oxide rau saum npoo (passivation), muab cov "stainless" stainless.
- Txaus nickel (ni):Yam tsawg kawg 1 0. 0%. Nickel ruaj khov lub cev siv leustenic crystal crystal, kom ntseeg tau zoo, formability, thiab weldability, txawm tias thaum kub kub.
- Ntxiv molybdenum (mo):Yam tsawg kawg 2. 0%. Nov yog tus tseem ceeb sib txawv los ntawm 304 stainless hlau. Molybdenum tseem ceeb boosts tsis kam rau pitting thiab crevice corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig muaj chlorides (zoo li dej hiav txwv, ntsev, tshuaj dawb) lossis cov kua qaub tsis muaj zog) lossis cov kua qaub tsis muaj zog) lossis cov kua qaub tsis muaj zog) lossis cov kua qaub tsis muaj zog) lossis cov kua qaub tsis muaj zog) lossis cov kua qaub tsis muaj zog) lossis cov kua qaub tsis muaj zog) lossis cov kua qaub tsis muaj zog) lossis cov kua qaub tsis muaj zog) lossis cov kua qaub tsis muaj zog) lossis cov kua qaub tsis muaj zog) lossis cov kua qaub tsis zoo
Tus qauv muab nruj me ntsis tsis sib xws los yog qhov tseem ceeb tshaj plaws rau lwm cov penbon (c), phosphorus (n), thiab muaj xws li tooj liab (CU). Cov pa roj carbon tsawg (A182 F316L) muaj rau cov ntawv thov uas yog vuam lossis raug rau kev kub ntxhov tuaj yeem ua rau mob carbide ntau. Qhov tseeb chemical muaj kev txwv yog qhov yuav tsum tau ua yog qhov yuav tsum tau ua thiab qhia tau los ntawm kev sim ntawm lub foundry thiab zeb tsim cov forging Tshuag.
A182 F316 Cov Khoom Siv Neeg Kho Tshuab
ASTM A182 F316 tsis yog hais txog kev siv tshuaj lom; Nws txhais qhov tsawg kawg ntawm kev ua kom muaj zog thiab ductility ua tiav kev zam txim thiab ua kom txias dua tshiab kom yaj thiab rov kho cov carbides thiab kho kom haum corrosion). Cov khoom tseem ceeb xws li muaj:
- Lub zog tensile: qhov kev ntsuas no qhov siab tshaj plaws yuam cov khoom tuaj yeem tiv thaiv thaum lub zog ua ntej tawg. ASTM A182 F316 feem ntau yuav tsum muaj lub zog tsawg kawg nkaus li ntawm 70 ksi (485 mpa).
- Tos lub zog: Qhov no qhia tias lub zog quab yuam uas cov khoom pib mus tas li deform (ncab) hauv qab kev thauj khoom. Nws qhia koj lub zog yam tsawg kawg nkaus uas yuav tsum tau khoov rau ib feem. Qhov tsawg kawg nkaus tau lees lub zog rau A182 F316 feem ntau yog 25 ksi (170 MPa) lossis siab dua. Qhov no yog qhov tseem ceeb rau cov khoom siv siab siab.
- Kev Tshawb Fawb: Qhov ntsuas no feem pua nce ntxiv nyob rau hauv qhov ntev ib daim ntawv xeem dhau los ua ntej kev kuaj mob Tensile. Qhov tsawg kawg nkaus elongation (piv txwv li, 30% lossis 40% lossis 40% los ntawm Bar Loj Thickness) kom cov khoom siv tau txaus du. Ductility yog qhov tseem ceeb heev vim tias nws tso cai rau cov khoom kom nqus lub zog tsis muaj dab tsi sai li sai, qhov uas tseem ceeb rau kev nyab xeeb.
- Hardness: Thaum tsis tas ib qho kev lees paub tseem ceeb hauv Base Feedification (feem ntau yog siv rau kev siv cov khoom siv kom ntseeg tau (NACE MR0175 \/ ISO 15156). Hardness yog cov kev sim ua ib txwm muaj raws li nws tau qhia nrawm ntawm cov khoom.
A182 F316 APPS
Tso cai lub rooj sib tham t182 f316 yog tseem ceeb heev rau hauv cov tshuab yuav tsum muaj lub zog siab, siab tiv thaiv corrosion. Raug siv suav nrog:
- Yeeb nkab flanges: Txuas kav nqa cov kua ntshav lossis roj roj hauv siab. (Teev raws li ib feem ntawm Flange cov sib tham hauv qab ASME B16.5 \/ B16.47).
- Forged yeeb nkab: lauj tshib, tus nqi, cov tsev ua tsev ua ke, cov cuab yeej ua ke, kev hloov ntawm cov yeeb nkab khiav hauv cov kev pabcuam corrosive. (Feem ntau teev nyob rau hauv Asme B16.11).
- Valve lub cev thiab cov kav: Cov khoom siv tseem ceeb tswj tau kua dej ntws. Lub F316 cov khoom tau tiv thaiv ob qho tib si lub siab thiab cov kua dej tau ua.
- Cheebtsam siab: lub cev tsis muaj zog, cov nyom, thiab lwm yam forged txuas ntawm tso tsheb hlau tso tso tsheb hlau luam thiab reactors.
- Twj tso kua mis thiab compressor Casings \/ Qhov: Cheebtsam raug kom ntws tawm cov xov xwm corrosive hauv siab.
- Cov roj offshore thiab roj: cov khoom siv tshwm sim rau cov neeg muaj dej hiav txwv.
- Tshuaj lom neeg thiab petrochemical ua: siv cov kua qaub, alkalis, cov kuab tshuaj, thiab lwm yam tshuaj txhoj puab heev.
- Kws ua lag luam thiab kev ua khoom noj: qhov twg corrosion tsis kam thiab huv yog qhov tseem ceeb tshaj plaws.
