Kwi-ASTM A213, ukongeza kwiimfuno zeempawu zokuxinana kunye nobunzima, kufuneka ezi mvavanyo zilandelayo: Uvavanyo lokuTyatya kunye novavanyo lokuFlaring.
I-ASTM A213 T11(ASME SA213 T11) yi-alloy ephantsiityhubhu yentsimbi engenamthungoequlethe i-1.00–1.50% Cr kunye ne-0.44–0.65% Mo, eneempawu ezintle zokumelana nobushushu, ezifanelekileyo ukusetyenziswa kubushushu obuphezulu kunye noxinzelelo oluphezulu.
I-T11 isetyenziswa kakhulu kwi-iibhoyila, ii-superheater, kunye nezitshintshi zobushushu.Inombolo ye-UNS: K11597.
Umenzi kunye neMeko
Imibhobho yentsimbi ye-ASTM A213 T11 mayiyenziwe ngenkqubo engenamthungo kwaye mayigqitywe ngokushisa okanye ngokubandayo, njengoko kuchaziwe.
Unyango lobushushu
Imibhobho yentsimbi ye-T11 kufuneka ifudunyezwe ukuze ifudunyezwe ngokweendlela ezilandelayo, kwaye unyango lobushushu kufuneka lwenziwe ngokwahlukeneyo kwaye ukongeza ekufudunyezweni ukuze kwenziwe ubushushu.

Ezinye Izinto zoVavanyo
Uluhlu lweMilinganiselo
Ubukhulu beetyhubhu ze-ASTM A213 T11 kunye nobukhulu bodonga zihlala zixhotyiswe ngobubanzi bangaphakathi obuqala kwi-3.2 mm ukuya kububanzi bangaphandle obuyi-127 mm, kunye nobukhulu bodonga obuncinci obuqala kwi-0.4 mm ukuya kwi-12.7 mm.
Ezinye iisayizi zeepayipi zentsimbi ze-T11 nazo zinokubonelelwa, ukuba nje zonke ezinye iimfuno ze-ASTM A213 ziyafezekiswa.
Ukunyamezelana koBungqingqwa bodonga
Ukunyamezelana kobukhulu bodonga kufuneka kumiselwe ngokusekelwe kwiimeko ezimbini ezilandelayo: nokuba umyalelo uchazwe ngokwenani elincinci lodonga okanye ubungakanani bodonga obuqhelekileyo.
1.Ubuncinci bobukhulu bodonga: Iya kuthobela iimfuno ezifanelekileyo zeCandelo 9 le-ASTM A1016.

2.Ubukhulu obuphakathi bodonga: Kwiityhubhu ezenziwe ngokubanda, umahluko ovumelekileyo yi-±10%; kwiityhubhu ezenziwe ngokubanda, ngaphandle kokuba kuchazwe ngenye indlela, iimfuno mazihambelane netheyibhile elandelayo.
