I-ASTM A213 T22, eyaziwa nangokuthi i-ASME SA213 T22, iyipayipi lensimbi elingenamthungo elinomucu ophansi one-chromium engu-1.90–2.60% kanye ne-molybdenum engu-0.87–1.13% njengezinto eziyinhloko zokuhlanganisa, ezivame ukusetshenziswa kuma-boiler, kuma-superheater, kanye nama-heat exchanger ezindaweni ezinokushisa okuphezulu, ezinomfutho ophezulu.
Isikhundla se-UNS yi-K21590.
Insimbi yeBotopungumhlinzeki wamapayipi ensimbi ye-alloy ochwepheshe futhi onokwethenjelwa eShayina, okwazi ukuhlinzeka ngokushesha ngamapayipi ensimbi ye-alloy asezingeni eliphezulu kumaphrojekthi akho.
Yonke imikhiqizo isekela ukuhlolwa komuntu wesithathu, futhi singaphinde sinikeze izinto zokufakelwa ezifana ne-alloy ezifana nezindololwane nezinye izesekeli zamapayipi.
Amapayipi ensimbi e-T22 kumele enziwe yi-inqubo engenamthungofuthi kufanele kube yisiqedi esishisayo noma esibandayo, njengoba kuchaziwe.
Wonke amapayipi ensimbi e-T22 kufanele aphinde afudunyezwe ukuze kulungiswe ukushisa, okumele kwenziwe ngokwehlukana futhi ngaphezu kokushisa ukuze kufakwe ukushisa.
Izindlela zokwelapha ukushisa ezivunyelwe ziwuku-annealing okugcwele noma okungashisi kakhulu, noma ukwenza kube ngokwejwayelekile futhi kube sesimweni esihle.

Ngaphezu kwalokho, izakhiwo zemishini ze-ASTM A213 T22 ziyafana neze-T2, T5, T5c,T11, T17, kanye ne-T21.
Ubukhulu bamapayipi e-ASTM A213 T22 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.
Vele, uma iphrojekthi yakho idinga osayizi abahlukile, lokho kuvunyelwe, inqobo nje uma zonke ezinye izidingo ezisebenzayo ku-ASTM A213 zihlangatshezwa.
Izidingo zokubekezelelana kobukhulu be-ASTM A213 ziyafana futhi zibhalwe ohlwini lwe-Amapayipi ensimbi e-alloy e-T11Ungachofoza ukuze uzibuke uma kudingeka.
Amapayipi ensimbi angenamthungo e-ASTM A213 T22 asetshenziswa kabanzi ezimweni zesevisi zokushisa okuphezulu kanye nokucindezela okuphezulu, ikakhulukazi embonini yokuphehla ugesi, i-petrochemical, kanye ne-oyela negesi.
Izinhlelo zokusebenza ezijwayelekile zifaka:
Amapayipi ebhoyilazisetshenziselwa ama-superheater, ama-reheater, kanye nama-economizer ezitshalweni zamandla.
Izishintshi zokushisazisetshenziswa ezitshalweni zamakhemikhali kanye ne-petrochemical.
Amapayipi esithando somlilozisetshenziswa ezisetshenziswa ezithandweni zokushisa okuphezulu.
Amapayipi omusizisetshenziselwa ukuthwala umusi ocindezela kakhulu ezitshalweni zezimboni.
