Qhov kev hloov kho microstructural no ua rau muaj txiaj ntsig zoo rau cov khoom siv lub zog creep rupture thaum lub sij hawm ntev - kev pabcuam ntawm qhov kub siab tshaj 600 degree, ua rau nws zoo tagnrho rau kev siv xws li petrochemical cracking furnace tubes thiab heater tubes.
Kev Paub Txog Engineering tiag tiag thiab teeb meem
Refinery Rauv Tubes Case
Hauv ethylene cracking furnaces, engineers feem ntau qhia tias:
316 stainless hlab tsis nyob rau hauv lub hlis nyob rau hauv thermal cycling
Incoloy 800H ncua kev pab cuam lub neej mus rau 3-8 xyoo nyob ntawm kev ua haujlwm nyuaj
Peb siv 800-series alloy, yog li vim li cas nws tsis ua haujlwm?
Feem ntau, nws los rau qhov sib txawv me ntsis ntawm Incoloy 800 thiab 800H. Nws tsis yog cov khoom siv xwb -nws yog qhov nws tau kub li cas- kho thiab nws ua li cas nws tswj cov kev ntxhov siab hauv koj qhov chaw tshwj xeeb.
Common Field Issues Tshaj Tawm:
1. Kev npaj txhij txog creep deformation nyob rau hauv cov tub rauv
Ua rau: siv tus qauv 800 tsis yog 800H
2. Weld tawg thaum lub sij hawm kaw
Yog vim li cas: tsis zoo muab tub lim xaiv
3. Scaling thiab oxidation ntawm 750℃+
Ua rau: tsis txaus alloy thickness los yog qib tsis raug
Yuav ntsuas li cas siab -kub oxidation thiab carburization tsis kam ntawm Incoloy 800H kav hauv petrochemical chav hloov pauv?
Hauv chav methane hloov kho (SMR) thiab kev ua haujlwm ntawm lub cub tawg, cov chromium - nplua nuj oxide zaj duab xis nyob rau saum npoo ntawm 800H piping zoo inhibits sab hauv diffusion ntawm carbon atoms. Kev ntsuam xyuas yuav tsum tsom mus rau qhov kub thiab txias hloov pauv, cov pa roj carbon zoo ntawm cov cua, thiab cov phab ntsa thickness uniformity los xyuas kom meej tias qhov tsis ua hauj lwm ntxov vim oxide scale spallation tsis tshwm sim thaum lub sij hawm siab - kub thermal cycling.
Puas yog koj tab tom qhia txog txoj cai "H-Qib" rau koj daim ntawv thov siab -temp?
Kuv tau pom ntau txoj haujlwm ua rau muaj kev cuam tshuam rau kev yuav khoom lossis, qhov phem dua, kev ua haujlwm tsis zoo vim tias tsis muaj qhov pom tseeb ntawm cov kev txwv carbon thiab cov qoob loo loj. Ntawm 1100℃F thiab siab dua, chemistry tseem ceeb:
✅ 800H (UNS N08810): Tswj cov pa roj carbon monoxide rau kev nkag siab zoo dua.
✅ 800HT (UNS N08811): Txwv Al+Ti qib kom muaj kev ntxhov siab ntau tshaj - kev ua haujlwm tawg.
Cov tswv yim engineers:
- Nco ntsoov xyuas UNS N08810 (800H) vs N08800 (800)
- Tsis txhob hloov cov hlau tsis muaj steel 310S rau lub sijhawm ntev - qhov kev pab cuam rauv taws
