Dab tsi yog ASTM A182?
Yog tias koj ua haujlwm nrog cov kav dej nrog cov kav dej, flanges, lossis fittings nyob rau hauv kev lag luam xws li kev lag luam, koj yuav muaj tshuaj lom neeg ATTM A {}} Tsis yog lwm cov ntaub ntawv ua ke; Nws yog qhov tseem ceeb qhia kev tsim kho los ntawm Astm thoob ntiaj teb . nws txoj haujlwm? Los txhais cov kev cai kom muaj rau forged lossis rolling alloy thiab siab} Cov ntaub ntawv tsim nyog cov khoom tseem ceeb, thiab siv cov khoom siv tsis zoo, thiab kuaj kom raug, thiab ntsuas kom muaj kev nyab xeeb thiab kev ntseeg tau nyob rau hauv cov kev mob xav . nws yog lub pob zeb ua kom muaj kev nyab xeeb thiab kev ntseeg siab hauv cov ceg txheem loj.
Cov ntaub ntawv dab tsi ASTM A182 npog?
ASTM A182 muab ntau cov tsev neeg ntawm cov cuab yeej tseem ceeb, kev tiv thaiv kom sov thiab corrosion. Cov pab pawg tseem ceeb yog:
- Ferritic thiab martensitic stainless hlau: cov no muaj lub zog zoo, feem ntau siv rau kev kub siab thiab qhov tseeb ntawm F6 (FORT HEEV
- Austenitic Stainless hlau: Cov no yog cov yeej ntawm corrosion tsis kam thiab ua kom muaj kev sib nqus thiab yooj yim} Lawv tsis muaj kev sib nqus thiab muaj kev sib nqus, f321, thiab f {348.
- Nickel-based alloys: rau qhov tsis tshua muaj cua sov - asoy 20 1 20s like like like like, lossis F62 (Alloy 825) {} Cov alloys tseem kim heev tab sis Qhov tseem ceeb rau cov ntawv thov tseem ceeb .
Nkag siab ATM A182 Qib
Hauv txhua cov khoom siv pab pawg, Astm A182 txhais tau tias yog tus lej "F91, f44, f44, f44, f4,}
- Lub cev muaj tshuaj lom neeg:Ntau npaum li cas chromium, npib tsib, molybdenum, carbon, thiab lwm cov ntsiab lus yuav tsum yog lub zog, thiab nws coj li cas thaum muaj siab kub.
- Yuav tsum muaj neeg kho tshuab cov khoom:Qhov tsawg kawg nkaus lub zog (ntau npaum li cas yuam nws tuaj yeem siv ua ntej khoov lossis tawg ua ntej kev ua txhaum kev ua kom muaj kev sib tw ua ntej
- Kev Kho Cua Sov:Cov cua sov tshwj xeeb thiab cov txheej txheem cua txias (zoo li annealing, quenching thiab ntsuas anevering) yuav tsum tau ua tiav micruction microstructure thiab cov khoom rau qib ntawd.
ASTM A182 xav tau thiab kuaj
Ua kom meej qhov sib ntsib ANTM A182 tsis yog kev twv; Nws cuam tshuam cov kev cai nruj thiab sim . tus qauv ua tiav:
- Tshuaj Ntsuam Xyuas Tshuaj: Ib qho qauv los ntawm txhua qhov kub ntawm Moly Steel (lossis tus tswv Alloy rau kev paub txog cov tshuaj lom neeg ua tau raws li cov kev xav tau qib tshwj xeeb {}}
- Kev Kuaj Txhua Yam: Cov qauv raug coj los ntawm kev ntsuas ntau yam (lossis lub zog ua kom zoo tib yam
- Kev Kho Cua Sov: Txhua qhov kev zam txim yuav tsum yauv kho cov txheej txheem sov (kub, lub sijhawm, cov ntaub ntawv txias rau kev ua tiav rau kev ua kom muaj kev kho cua sov kom raug yog qhov yuav tsum tau ua kom sov kub yog qhov yuam kev.
- Kev kuaj xyuas zoo & tshuaj xyuas: Cov qauv qhia ntawv yuav tsum tau kuaj pom tseeb (txhua qhov xav tau kev soj ntsuam kom pom tseeb), thiab cov cim cua sov}
Yuav ua li cas ANTM A182 ntu
ASTM A182 pib li cov blocks tawv lossis cov khoom siv cua sov (zoo li cov cua sov (zoo li cov yas ua kom pom tseeb) thiab yog ib qho tseem ceeb heev (zoo li cov cua sov) hlau, raws li cov nplej ntws kom ua raws li lub denser, muaj zog, thiab ua tiav qhov kev zam txim ntawm kev ua kom yooj yim, thiab ua tiav qhov kev ua kom tiav ntawm kev ua kom sov, thiab ua tiav qhov kev ua kom tau muaj zog, thiab Microstructure {{}} nruj kev tswj hwm thoob plaws tus txheej txheem ua kom ua raws li kev ua raws li.
ASTM A182 Cov Khoom Siv Khoom Siv
Koj yuav pom ASTM A182 dhau txhua qhov chaw xav tau kev ua haujlwm nyob rau hauv lub siab thiab tshav kub yog qhov tseem ceeb:
- Roj Thiab Roj:Cov Pipelines High-Wellheads, Christmas ntoo, Offshore platforms, Refshore platforms, Refinines, hloov pauv cua sov) .
- Lub zog tiam:Cov roj hmab, chav dej, tshuab, thiab cov tshuab ntsuas hauv cov roj pob zeb thiab cov hluav taws xob nuclear {}}
- Tshuaj thiab Petrochemical:Reactors, cov kab ua kom sov
- Kev Kub Siab Kub:Cov cuab yeej siv nyob rau hauv kev lag luam zoo li cov tshuaj, ua zaub mov noj (kom tsis muaj menyuam), qhov twg kub thiab siab yog qhov tseem ceeb {}}
- General siab cov kev pab:Tej yam system uas cov khoom siv yuav tsum muaj cov kua lossis roj ntxiv rau hauv cov siab tseem ceeb, tshwj xeeb nrog cov siab kub .
Vim li cas ATM A182 yog qhov tseem ceeb
Hauv cov ntsiab lus yooj yim, ANTM A182 muab cov lus qhia ua ke thiab kev kho kom muaj zog, thiab cua sov} qhov {{{}}} los ntawm kev xav tau kev tiv thaiv nruj, kev ua tsis taus pa, thiab kev ua kom muaj kev sib raug zoo, thiab kev ua kom muaj kev sib raug zoo, thiab kev ua kom muaj kev sib raug zoo, thiab kev ua kom muaj kev sib raug zoo, thiab kev ua kom muaj kev sib raug zoo, thiab kev ua kom muaj kev sib raug zoo thoob ntiaj teb. Thaum koj pom ASTM A182 ntawm cov ntawv pov thawj khoom lossis ib feem cim, nws qhia tias muaj kev sib xyaw ua ke los nrog cov kev mob hnyav tshaj.
