SA213 ishubhu yebhoyila enomfutho ophezuluuchungechunge luyiishubhu yebhoyila enomfutho ophezuluuchungechunge. Kufanelekela amashubhu ensimbi e-ferritic ne-austenitic angenamthungo anobukhulu obuncane bodonga lwama-boiler nama-superheater kanye namashubhu ensimbi e-austenitic yama-heat exchanger.

Amapayipi okushisa angaphezulu asetshenziswa kuma-boiler aphansi naphakathi (ingcindezi yokusebenza ngokuvamile ayidluli ku-5.88Mpa, izinga lokushisa lokusebenza lingaphansi kuka-450℃); asetshenziswa kuma-boiler aphakeme (ingcindezi yokusebenza ngokuvamile ingaphezu kuka-9.8Mpa, izinga lokushisa lokusebenza liphakathi kuka-450℃ ~ 650℃) ) amapayipi okushisa angaphezulu, ama-superheater, ama-reheater, amapayipi embonini ye-petrochemical, njll.

I-ASME SA213 T12Ipayipi lensimbi ye-alloy, elihamba phambili kumapayipi ensimbi angenamthungo aseMelika, lisetshenziswa kabanzi kuphethiloli, embonini yamakhemikhali, kumandla kagesi nakwezinye izinkambu zezimboni. Lolu hlobo lwepayipi lensimbi lwenziwe ngensimbi esezingeni eliphezulu. Ngemva kokucutshungulwa ngokucophelela ezinqubweni eziningi, linamandla aphezulu kanye nokumelana nokugqwala okuphezulu. Lingahlangabezana nezidingo zokusetshenziswa ezindaweni ezahlukahlukene eziyinkimbinkimbi.

Inqubo yayo yokukhiqiza iyinkimbinkimbi futhi iyamangalisa, okuhlanganisa ukuncibilikisa, ukugoqa, ukubhoboza, ukudonsa okubandayo, ukwelashwa kokushisa nezinye izixhumanisi. Ngesikhathi senqubo yokukhiqiza, ipayipi lensimbi lihlolwa amaphutha amaningi kanye nokuhlolwa okungabhubhisi ukuqinisekisa ikhwalithi nokuthembeka kwalo okuhle kakhulu. Kukhona nokuhlaziywa kwamakhemikhali okuhlukahlukene, ukuhlaziywa kwe-metallographic kanye nezinye izivivinyo ukuqinisekisa ukuthi ukwakheka kwalo, isakhiwo senhlangano, ukusebenza kanye nezinye izinkomba kuhlangabezana nezidingo ezijwayelekile.

Izici zeI-ASME SA213 T12ipayipi lensimbi ye-alloy yile elandelayo:
1. Amandla aphezulu: Inamandla aphezulu okudonseka kanye nephuzu lokukhiqiza, futhi ingamelana nemithwalo emikhulu kanye nokushayisana.
2. Ukumelana nokugqwala okuphezulu: Inokumelana nokugqwala okunamandla ezindaweni ezahlukahlukene eziyinkimbinkimbi, njenge-asidi, ama-alkali, usawoti kanye nezinye izinto zamakhemikhali kanye nezindawo ezibucayi njengezinga lokushisa eliphezulu kanye nezinga lokushisa eliphansi.
3. Ukusebenza kahle kokushisela: Yenziwe ngensimbi esezingeni eliphezulu, ayivami ukuqhekeka, ukumbozwa kanye nezinye izinkinga ngesikhathi sokushisela, okuqinisekisa ikhwalithi nokuthenjwa kokushisela.
4. Uhla olubanzi lwezicelo: Lusetshenziswa kabanzi embonini kaphethiloli, yamakhemikhali, amandla kagesi kanye neminye imikhakha yezimboni, njengemipayipi kawoyela negesi, amabhoyila, ama-reactor kanye neminye imishini.
