ASTM A213 T9, yomwe imadziwikanso kuti ASME SA213 T9, ndi yolimba kwambirichubu chachitsulo chopanda msokoamagwiritsidwa ntchito pa ma boiler, ma superheater, ndi ma heat exchangers.
T9 ndi aloyi ya chromium-molybdenum yokhala ndi 8.00–10.00% chromium ndi 0.90–1.10% molybdenum. Ili ndi mphamvu yocheperako yogwira ntchito ya 415 MPa ndi mphamvu yocheperako yogwira ntchito ya 205 MPa. Ndi mphamvu yake yabwino kwambiri yogwira ntchito kutentha kwambiri, kukana okosijeni, komanso kukana kukwawa, T9 imagwira ntchito bwino kwambiri pakakhala kutentha kwambiri komanso kuthamanga kwambiri.
Monga katswiri wopereka chitoliro chachitsulo cha alloy komanso wogulitsa zinthu zambiri ku China,Chitsulo cha BotopIkhoza kupereka mapaipi achitsulo a T9 mwachangu pamapulojekiti anu, okhala ndi khalidwe lodalirika komanso mitengo yopikisana.
Katundu woperekedwa ku ASTM A213 ayenera kutsatira zofunikira za ASTM A1016, kuphatikizapo zofunikira zina zowonjezera zomwe zafotokozedwa mu oda yogulira.
ASTM A1016: Mafotokozedwe Okhazikika a Zofunikira Zonse za Ferritic Alloy Steel, Austenitic Alloy Steel, ndi Stainless Steel Tubes
Wopanga ndi Mkhalidwe
Mapaipi achitsulo a ASTM A213 T9 ayenera kupangidwa ndi njira yopanda msoko ndipo ayenera kumalizidwa kutentha kapena kumalizidwa ozizira, monga momwe zafotokozedwera.
Kutentha Chithandizo
Mapaipi achitsulo a T9 ayenera kutenthedwanso kuti atenthedwe motsatira njira zotsatirazi, ndipo kutentha kuyenera kuchitidwa padera komanso kuwonjezera pa kutentha kuti apange kutentha.

Akayikidwa mu boiler kapena chubu, machubuwo ayenera kupirira kukula ndi kupangika kwa mikanda popanda kuwonetsa ming'alu kapena zolakwika zilizonse. Machubu a Superheater, akagwiritsidwa ntchito bwino, ayenera kupirira ntchito zonse zopangira, kuwotcherera, ndi kupindika zomwe zimafunika kuti zigwiritsidwe ntchito popanda kukhala ndi zolakwika.
ASTM A213 T9 ndi chubu chopanda msoko cha Cr-Mo chomwe chimadziwika ndi mphamvu zake zabwino kwambiri zotentha kwambiri, kukana kugwedezeka, komanso kukana dzimbiri lotentha kwambiri. Chimagwiritsidwa ntchito kwambiri m'malo otentha kwambiri komanso opanikizika kwambiri. Ntchito zambiri zimaphatikizapo:
Amagwiritsidwa ntchito m'mizere ya nthunzi yotentha kwambiri, malo otenthetsera a boiler, zotsika, zokwezera, ndi zigawo zina zomwe zimagwira ntchito kutentha kwambiri komanso kupanikizika kosalekeza.
2. Machubu Otenthetsera ndi Otenthetsera Zinthu
Yabwino kwambiri potenthetsa kwambiri ndi kubwezeretsanso kutentha chifukwa cha kukana kwake kukwera komanso kugwira ntchito bwino kwambiri.
3. Machubu Osinthira Kutentha
Imagwiritsidwa ntchito m'mafakitale oyeretsera, mafakitale opanga mankhwala, ndi mafakitale opanga magetsi kuti igwiritsidwe ntchito posinthana kutentha kwambiri.
4. Makampani Ogulitsa Mafuta
Amagwiritsidwa ntchito m'machubu ophwanyika otentha kwambiri, machubu a hydrotreater reactor, machubu a ng'anjo, ndi mayunitsi ena opangira kutentha kwambiri.
5. Malo Opangira Magetsi
Yoyenera kugwiritsa ntchito mapaipi okhala ndi mphamvu yamphamvu komanso kutentha kwambiri m'mafakitale opanga magetsi opangidwa ndi malasha, m'mafakitale opanga mphamvu zotayira zinyalala, komanso m'malo opangira magetsi okhala ndi biomass.
6. Ng'anjo Zamakampani
Amagwiritsidwa ntchito pa machubu owala ndi machubu a uvuni omwe amafuna kukana kutentha kwambiri.
