Alloy 2205 tubing kuj tseem siv rau hauv kev lag luam tsheb thiab aerospace vim lawv cov khoom siv zoo heev, lub zog, thiab kev tiv thaiv corrosion.
ASTM A928 UNS S31803 Txheem:yog ib qho kev qhia tshwj xeeb uas suav nrog hluav taws xob-fusion-welded (EFW) duplex stainless hlau yeeb nkab haum rau corrosive lossis high-temperature service. Lub duplex stainless hlau UNS S31803 2205 yog tus cwj pwm los ntawm nws ob theem microstructure, ua ke ob qho tib si austenitic thiab ferritic theem, ua rau cov kav dej uas tuaj yeem tiv taus qhov kub thiab txias, nrog rau qhov hnyav hnyav xws li cov uas pom hauv ntug dej hiav txwv. kev lag luam roj thiab roj.
Kev siv ASTM A928 UNS S31803 Duplex EFW Pipes:
1. Tshuaj thiab Petrochemical ua:
Qhov zoo heev corrosion kuj thiab lub zog ntawmA928 S31803ua kom nws zoo rau kev siv tshuaj thiab petrochemical kev lag luam. S31803 duplex tuaj yeem tiv taus qhov chaw corrosive uas muaj cov kua qaub, chlorides, thiab lwm yam khoom hnyav.
2. Kev lag luam roj thiab roj:
Duplex stainless hlau kav yog feem ntau ua hauj lwm nyob rau hauv cov roj thiab roj sector, tshwj xeeb tshaj yog nyob rau hauv cov kev siv xws li offshore platforms thiab subsea pipelines. Cov1.4462 UNS S31803Cov khoom siv tiv thaiv corrosion thiab siab zog yog qhov zoo nyob rau hauv cov kev xav tau ib puag ncig.
3. Thaum tshav kub kub Exchangers:
ASME SA928 UNS S31803 welded kavyog feem ntau siv nyob rau hauv fabrication ntawm tshav kub exchanger systems. Lub uns s31803 yeeb nkab cov khoom siv corrosion kuj thiab zoo thermal conductivity ua rau nws haum rau zoo hloov tshav kub hauv ntau yam kev lag luam.
4. Desalination Nroj Tsuag:
Muab nws cov tshuaj tiv thaiv rau chloride-induced corrosion, duplex stainless hlau yog nquag siv nyob rau hauv desalination nroj tsuag qhov twg seawater ua tiav los tsim dej tshiab.ASTM A928 alloy 2205 duplex kavtuaj yeem tiv taus cov xwm txheej hnyav cuam tshuam nrog cov txheej txheem desalination.
5. Pulp thiab Ntawv Kev Lag Luam:
Duplex 1.4462 stainless hlau yeeb nkabyog ua hauj lwm nyob rau hauv lub pulp thiab ntawv kev lag luam rau daim ntaub ntawv xws li tshuaj ua thiab cia vim nws tsis kam mus corrosion los ntawm ntau yam tshuaj siv nyob rau hauv daim ntawv ntau lawm.
6. Kev kho dej thiab cov kav dej phwj tuaj:
Lub corrosion kuj thiab durability ntawmASTM A928 Duplex 2205 Tubeua kom nws haum rau siv hauv cov chaw kho dej thiab cov kav dej phwj tuaj uas raug cov tshuaj lom neeg thiab qhov chaw muaj corrosive.
7. Kev siv tus qauv:
Hauv qee qhov kev siv cov qauv uas muaj zog thiab corrosion kuj tseem ceeb heev,ASTM A928 UNS S31803 duplex EFW welded kavtej zaum yuav ua hauj lwm. Qhov no suav nrog cov khoom tsim kho hauv qhov chaw corrosive.
8. Mechanical thiab Structure Cheebtsam:
ASME SA 928 Duplex stainless hlau welded kavnrhiav kev siv nyob rau hauv ntau yam khoom siv thiab cov khoom siv thoob plaws hauv kev lag luam vim lawv qhov sib xyaw ua ke ntawm lub zog thiab corrosion kuj.
