Ku-ASTM A213, ngaphezu kwezidingo zezakhiwo zokubopha kanye nokuqina, kudingeka nokuhlolwa okulandelayo: Ukuhlolwa Kokugoba kanye Nokuhlolwa Kokuvutha.
I-ASTM A213 T11(ASME SA213 T11) iyi-alloy ephansiipayipi lensimbi elingenamthungoequkethe i-1.00–1.50% Cr kanye ne-0.44–0.65% Mo, enezakhiwo ezinhle kakhulu zokumelana nokushisa, ezifanele ukusetshenziswa kwezinga lokushisa eliphezulu kanye nengcindezi ephezulu.
I-T11 ivame ukusetshenziswa ku-amabhoyila, ama-superheater, kanye nama-heat exchanger.Inombolo ye-UNS: K11597.
Umkhiqizi kanye Nesimo
Amapayipi ensimbi e-ASTM A213 T11 kumele enziwe ngenqubo engenamthungo futhi kufanele aqedwe ngokushisa noma ngokubandayo, njengoba kuchaziwe.
Ukwelashwa Kokushisa
Amapayipi ensimbi e-T11 kufanele aphinde afudunyezwe ukuze kulungiswe ukushisa ngokwezindlela ezilandelayo, futhi ukwelashwa kokushisa kufanele kwenziwe ngokwehlukana futhi ngaphezu kokushisa ukuze kulungiswe ukushisa.

Ezinye Izinto Zokuhlola
Ububanzi Bobukhulu
Ubukhulu bamapayipi e-ASTM A213 T11 kanye nobukhulu bodonga ngokuvamile kufakwe ububanzi bangaphakathi obusukela ku-3.2 mm kuya kububanzi bangaphandle obungu-127 mm, kanye nobukhulu bodonga obuncane obusukela ku-0.4 mm kuya ku-12.7 mm.
Amanye amasayizi amapayipi ensimbi e-T11 nawo anganikezwa, uma nje zonke ezinye izidingo ze-ASTM A213 zihlangatshezwa.
Ukubekezelelana Kokujiya Kodonga
Ukubekezelela ukujiya kodonga kufanele kunqunywe ngokusekelwe ezimweni ezimbili ezilandelayo: ukuthi i-oda lichazwe ngokuya ngokujiya kodonga okuncane noma ukujiya kodonga okumaphakathi.
1.Ubukhulu bodonga obuncane: Kuzohambisana nezidingo ezifanele zeSigaba 9 se-ASTM A1016.
