Teb:
Teem sijhawm 80 cov kav dej yog tuab dua -walled dua li Schedule 40 cov kav dej, muab ntau yam zoo rau cov khoom siv roj turbine:
Ua kom muaj zog thiab ua haujlwm ntev: Cov phab ntsa tuab ntawm Teem 80 cov kav dej ua rau lawv tiv taus ntau dua rau lub siab sab hauv thiab sab nraud kev ntxhov siab, uas yog qhov tseem ceeb hauv siab - kev ntxhov siab ib puag ncig xws li roj turbines.
Kev ntsuas siab dua: Teem sijhawm 80 cov kav dej muaj qhov ntsuas siab dua, tso cai rau lawv tuaj yeem tiv taus qhov kub siab thiab kev ua haujlwm hnyav uas pom hauv cov roj turbines.
Kev tiv thaiv zoo dua rau kev qaug zog: Cov phab ntsa tuab muab kev tiv thaiv ntxiv rau thermal cycling thiab qaug zog, ua kom lub neej ntev kev pab cuam thiab kev ntseeg siab nyob rau hauv cov huab cua huab cua turbines.
Txhim kho Leak Resistance: Cov phab ntsa tuab ntxiv muab kev tiv thaiv zoo rau cov dej ntws los yog kev tawg, uas yog qhov tseem ceeb hauv kev tiv thaiv kev ua tsis tiav hauv cov roj turbine.
4. Dab tsi yog cov kev siv ntawm Inconel 600 kav dej hauv cov roj turbines?
Teb:
Inconel 600 kav, tshwj xeeb tshaj yog cov ua rau ASTM B167 UNS N06600 cov qauv, feem ntau yog siv nyob rau hauv ntau yam roj turbine Cheebtsam vim lawv zoo heev zog nyob rau hauv kub thiab kev ntxhov siab. Cov ntawv thov ib txwm muaj xws li:
Turbine Exhaust Systems: Inconel 600 kav yog siv nyob rau hauv lub tso pa system ntawm cov pa turbines, qhov twg kub thiab corrosive tso pa gases muaj ntau.
Thaum tshav kub kub Exchanger Tubes: Lawv feem ntau siv nyob rau hauv lub tshav kub exchangers nyob rau hauv cov roj turbine xyaw, uas ua hauj lwm nyob rau hauv siab thermal stress thiab xav tau cov ntaub ntawv uas yuav tiv taus oxidation thiab thermal qaug zog.
Combustion Chambers: Inconel 600 muaj peev xwm tiv taus qhov kub thiab txias thiab corrosion ua rau nws zoo tagnrho rau cov khoom uas raug tshav kub thiab combustion gases.
Gas Turbine Cooling Systems: Vim lawv muaj kev tiv thaiv siab rau thermal qaug zog, Inconel 600 kav yog siv rau hauv cov tshuab cua txias uas yuav tsum tau muaj zog thiab kub tsis kam.
5. Yuav ua li cas ASTM B167 UNS N06600 Inconel 600 piv rau lwm yam ntaub ntawv, xws li stainless hlau, rau roj turbine siv?
Teb:
Piv rau stainless hlau, Inconel 600 muaj ntau qhov zoo rau kev siv roj turbine:
Kev kub siab dua: Thaum cov hlau tsis muaj steel feem ntau tuaj yeem tiv taus qhov kub txog li 1,500℃F (815 degree), Inconel 600 tuaj yeem ua haujlwm tau zoo ntawm qhov kub txog 2,000℃F (1,093 degree), ua rau nws haum rau cov huab cua huab cua.
