Ipayipi lensimbi elingenamthungo le-alloy liyinto esebenza kahle kakhulu esetshenziswa kabanzi embonini nasekwakhiweni. Isici salo esiyinhloko ukuthuthukisa izakhiwo zemishini, ukumelana nokugqwala kanye nokumelana nokushisa okuphezulu kwamapayipi ensimbi ngokungeza izakhi ezahlukene ze-alloy, njenge-chromium, i-molybdenum, i-nickel, njll. Okulandelayo ezinye zezinto ezivamile zepayipi lensimbi elingenamthungo le-alloy:

I-ASTM A335Uchungechunge lwe-P:

P5: Ipayipi lensimbi le-P5 liqukethe i-chromium engu-5% kanye ne-molybdenum engu-0.5%, linokumelana okuhle kwe-oxidation kanye namandla okushisa aphezulu, futhi livame ukusetshenziswa emipayipini ye-steam eshisa kakhulu kanye nasembonini ye-petrochemical.
P9: Ipayipi lensimbi le-P9 liqukethe i-9% chromium kanye ne-1% molybdenum, linokumelana okuphezulu kwe-oxidation kanye nokumelana nokugqwala kune-P5, futhi lifanelekela indawo enokushisa okuphezulu kanye nokucindezela okuphezulu.
P11: Ipayipi lensimbi le-P11 liqukethe i-chromium engu-1.25% kanye ne-molybdenum engu-0.5%, lisebenza kahle kakhulu, futhi lisetshenziswa kabanzi kuma-boiler okushisa okuphezulu kanye nama-heat exchanger.
P22: Ipayipi lensimbi le-P22 liqukethe i-chromium engu-2.25% kanye ne-molybdenum engu-1%, linamandla okushisa aphezulu kanye nokumelana nokushiswa kwe-oxidation, futhi livame ukusetshenziswa kumapayipi okushisa aphezulu kanye nokucindezela okuphezulu ezitshalweni zamandla kanye nasembonini ye-petrochemical.
I-P91: Ipayipi lensimbi le-P91 liyinsimbi ye-chromium ephezulu kanye ne-molybdenum ephezulu, equkethe i-9% chromium kanye ne-1% molybdenum, futhi iqukethe inani elincane le-vanadium kanye ne-nitrogen. Linamandla okushisa aphezulu kakhulu kanye namandla okukhasa futhi lisetshenziswa kabanzi ezitshalweni zamandla ezibucayi kakhulu kanye nezibucayi kakhulu.
I-ASTM A213Uchungechunge lwe-T:

T11: Ipayipi lensimbi le-T11 liqukethe i-1.25% ye-chromium kanye ne-0.5% ye-molybdenum, efana ne-P11, futhi lisetshenziswa kakhulu kuma-heat exchanger nama-boiler okushisa okuphezulu.
T22: Ipayipi lensimbi le-T22 liqukethe i-chromium engu-2.25% kanye ne-molybdenum engu-1%, efanelekile ezindaweni ezinokushisa okuphezulu kanye nokucindezela okuphezulu, futhi isetshenziswa kabanzi ezitshalweni zikagesi kanye nasezimbonini ze-petrochemical.
I-T91: Ipayipi lensimbi le-T91 lifana ne-P91, liqukethe i-9% chromium kanye ne-1% molybdenum, futhi liqukethe i-vanadium ne-nitrogen. Linamandla okushisa aphezulu kakhulu kanye nokumelana nokukhasa futhi lifanele izitshalo zamandla ezibucayi kakhulu nezibucayi kakhulu.
I-EN 10216-2:
10CrMo9-10: Lena ipayipi lensimbi elihlanganisiwe laseYurophu eliqukethe i-chromium ne-molybdenum, elinamandla okushisa aphezulu kanye nokumelana nokugqwala, elivame ukusetshenziswa ezitshalweni zikagesi kanye nasezimbonini ze-petrochemical.
Amapayipi ensimbi angenamthungo e-alloy athuthukisa kakhulu ukusebenza okuphelele kwamapayipi ensimbi ngokufaka izakhi ezithile ze-alloy ensimbini, futhi afanelekela izimo zokusebenza ezahlukahlukene ezimbi kakhulu. Amapayipi ensimbi e-P series kanye ne-T series ane-chromium ephezulu kanye ne-molybdenum ephezulu, njenge-P91 kanye ne-T91, amelela isiqondiso sokuthuthukiswa kwezinto zesimanje zokushisa okuphezulu kanye nokucindezela okuphezulu futhi asetshenziswa kabanzi ezitshalweni zamandla ezibucayi kakhulu nezibucayi kakhulu. Ukukhetha izinto ezifanele zepayipi lensimbi engenamthungo e-alloy akugcini nje ngokuqinisekisa ukuphepha nokusebenza okuzinzile kwephrojekthi, kodwa futhi kuthuthukisa kakhulu impilo yesevisi kanye nokusebenza kahle kwemishini.
