Ipayipi lensimbi ye-alloy lisetshenziswa kakhulu esitshalweni sikagesi, esitshalweni sikagesi senuzi, kubhoyila enomfutho ophezulu, ku-superheater enokushisa okuphezulu, ku-reheater kanye nakwamanye amapayipi nemishini enomfutho ophezulu kanye nokushisa okuphezulu. Lenziwe ngensimbi yekhabhoni esezingeni eliphezulu, insimbi yokwakheka kwe-alloy kanye nensimbi engagqwali engamelana nokushisa ngokugoqa okushisayo (ukukhipha, ukunwebeka) noma ukugoqa okubandayo (ukudweba).
Ipayipi lensimbi nepayipi elingenamthungo linokuxhumana nomehluko, alinakudidaniswa. Ipayipi legolide lichazwa njengepayipi lensimbi ngokwezinto zokukhiqiza (okungukuthi, izinto). Njengoba igama lisho, liyipayipi elenziwe nge-alloy. Ipayipi elingenamthungo lichazwa njengepayipi lensimbi (elingenamthungo kanye nelingenamthungo) ngokwenqubo yokukhiqiza.
Ipayipi le-alloy uhlobo lwepayipi lensimbi elingenamthungo, elihlukaniswe ngepayipi elingenamthungo lesakhiwo kanye nepayipi le-alloy elingashisi kakhulu. Ngokuyinhloko lihlukile ezindinganisweni zokukhiqiza kanye nemboni yamapayipi e-alloy, amapayipi e-alloy afakwe i-anneal kanye ne-tempered alloy ashintsha izakhiwo zemishini. Ukuhlangabezana nezimo zokucubungula ezidingekayo. Ukusebenza kwalo kuphakeme kunepayipi lensimbi elivamile elingenamthungo, ukwakheka kwamakhemikhali kuqukethe i-Cr eningi, ngakho-ke linokumelana nokushisa okuphezulu, ukumelana nokushisa okuphansi kanye nokumelana nokugqwala. Ipayipi elivamile elingenamthungo le-carbon alinazo izingxenye ze-alloy noma liqukethe inani elincane lezingxenye ze-alloy. Amapayipi e-alloy asetshenziswa kabanzi ku-petroleum, i-aerospace, amakhemikhali, amandla kagesi, i-boiler, i-military kanye neminye imboni, ngoba izakhiwo zemishini zamapayipi e-alloy ziyahlukahluka futhi kulula ukuzilungisa.

Izinto zombhobho wensimbi ezingenamthungo zihlukaniswe kanje: 10, 20, 35, 45, 40Mn2, 45Mn2, 27SiMn, 20Cr, 40Cr, 20CrMo, 35CrMo, 38CrMoA1, 50CrV, 30CrMnSi ASTM A500-98 lezi eziningana.

Izindinganiso zokusebenzisa amapayipi ensimbi angenamthungo:

1, isakhiwo sepayipi elingenamthungo (GB/T8162-2008) isetshenziselwa isakhiwo esijwayelekile kanye nesakhiwo somshini sepayipi lensimbi elingenamthungo.

2, ipayipi lensimbi elingenamthungo lokuthuthwa koketshezi (GB/T8163-2008) lisetshenziselwa ukuthuthwa kwamanzi, uwoyela, igesi kanye nolunye uketshezi lwepayipi lensimbi elingenamthungo elijwayelekile.

Ishubhu yensimbi engenamthungo yebhoyila enengcindezi ephansi nephakathi (3)GB3087-2008) isetshenziselwa ukukhiqiza izakhiwo ezahlukahlukene zepayipi lomusi elishisayo kakhulu lebhoyila elinomfutho ophansi nophakathi, ipayipi lamanzi abilayo kanye nepayipi lomusi elishisayo kakhulu lebhoyila kanye nepayipi lezitini eliyi-arch lensimbi yesakhiwo yekhabhoni esezingeni eliphezulu egoqwe ngokushisayo nangokubanda edonswe (egoqwe) ipayipi lensimbi elingenamthungo.

4, ishubhu yensimbi engenamthungo yebhoyila enomfutho ophezulu (GB5310-2008) isetshenziselwa ukwenziwa kwepayipi lamanzi elinomfutho ophezulu kanye nelingaphezulu komfutho elinokushisa okuphezulu ngensimbi yekhabhoni esezingeni eliphezulu, insimbi ye-alloy kanye nepayipi lensimbi engenasici elimelana nokushisa elingenamthungo.

5, imishini yomanyolo wamakhemikhali wepayipi lensimbi elingenamthungo elinomfutho ophezulu (GB6479-2000) ifanele izinga lokushisa lokusebenza elingu--40~400℃, ingcindezi yokusebenza engu-10~30Ma imishini yamakhemikhali kanye nepayipi lensimbi yesakhiwo sekhabhoni esezingeni eliphezulu kanye nepayipi lensimbi engenamthungo yensimbi.

6, ipayipi lensimbi elingenamthungo eliqhekeka ngophethiloli (GB9948-2006) ifanele ipayipi lesithando sokuhlanza i-petroleum, i-heat exchanger kanye nepayipi lensimbi elingenamthungo.
Izinto zepayipi lensimbi ye-alloy ngokuya ngobukhulu, imininingwane ingahlukaniswa ibe yi-12-42CrMO, T91, 30CrMo, 20G, 15CrMoV, Cr9Mo, 27SiMn, 10CrMo910, 15Mo3, 35CrMoV, 45CrMo, 15CrMoG, 12CrMoV, 45Cr, 16Mn 12Cr1MoV, 50Cr, 15CrMo, 45CrNiMo, njll.
