SA213 ishubhu ye-boiler enengcindezi ephezuluuchungechunge aishubhu ye-boiler enengcindezi ephezuluuchungechunge. Ifanele amashubhu ensimbi angenamthungo kanye ne-austenitic enogqinsi oluncane lodonga lwamabhayela nama-superheaters namashubhu ensimbi e-austenitic okushintshanisa ukushisa.

Amapayipi angaphezulu okushisa asetshenziswa kuma-boilers wengcindezi ephansi naphakathi (ingcindezi yokusebenza ngokuvamile ayinkulu kuno-5.88Mpa, izinga lokushisa elisebenzayo lingaphansi kuka-450 ℃); asetshenziswa kuma-boilers anengcindezi ephezulu (ingcindezi yokusebenza ngokuvamile ingaphezulu kuka-9.8Mpa, izinga lokushisa lokusebenza liphakathi kuka-450℃～650℃)) amashubhu angaphezulu okushisisa, ama-superheaters, ama-reheaters, amashubhu emboni ye-petrochemical, njll.

I-ASME SA213 T12ingxubevange steel ipayipi, umholi American standard amapayipi Seamless steel, isetshenziswa kabanzi petroleum, imboni yamakhemikhali, amandla kagesi kanye nezinye izimboni. Lolu hlobo lwepayipi lensimbi lenziwe ngensimbi yekhwalithi ephezulu. Ngemuva kokucubungula ngokucophelela ezinkambisweni eziningi, inamandla aphezulu kanye nokumelana nokugqwala okuphezulu. Ingakwazi ukuhlangabezana nezidingo zokusetshenziswa ezindaweni ezihlukahlukene eziyinkimbinkimbi.

Inqubo yokukhiqiza yayo iyinkimbinkimbi futhi inhle, okuhlanganisa ukuncibilika, ukugingqa, ukubhoboza, ukudweba okubandayo, ukwelashwa kokushisa nezinye izixhumanisi. Phakathi nenqubo yokukhiqiza, ipayipi lensimbi lithola amaphutha amaningi kanye nokuhlolwa okungabhubhisi ukuze kuqinisekiswe izinga layo elihle kakhulu nokuthembeka. Kukhona nokuhlaziywa kwamakhemikhali okuhlukahlukene, ukuhlaziywa kwe-metallographic nokunye ukuhlola ukuze kuqinisekiswe ukuthi ukwakheka kwayo, ukwakheka kwenhlangano, ukusebenza kanye nezinye izinkomba zihlangabezana nezidingo ezijwayelekile.

Izici zeI-ASME SA213 T12ingxubevange steel pipe imi kanje:
1. Amandla aphezulu: Inamandla aphezulu okudonsa kanye nephuzu lokukhiqiza, futhi ingakwazi ukumelana nemithwalo emikhulu nemithelela.
2. Ukumelana nokugqwala okuphezulu: Inokumelana nokugqwala okuqinile ezindaweni ezahlukahlukene eziyinkimbinkimbi, njengama-acids, ama-alkali, usawoti kanye nezinye izinto zamakhemikhali kanye nezimo ezimbi kakhulu ezifana nezinga lokushisa eliphezulu kanye nezinga lokushisa eliphansi.
3. Ukusebenza kahle kwe-welding: Yenziwe ngensimbi yekhwalithi ephezulu, ayithambekele ekuqhekekeni, ama-pores nezinye izinkinga ngesikhathi sokushisela, ukuqinisekisa ikhwalithi ye-welding nokuthembeka.
4. Uhlu olubanzi lwezicelo: Isetshenziswa kakhulu ku-petroleum, embonini yamakhemikhali, amandla kagesi nakwezinye izimboni, njengamapayipi kawoyela negesi, ama-boilers, ama-reactors nezinye izinto zokusebenza.
