I-T91futhiI-P91yizinsimbi ezimbili ezisetshenziswa kabanzi ze-martensitic stainless steels ezishisa kakhulu, ezinamandla aphezulu ezithathwe ohlelweni lwe-alloy lwe-9Cr-1Mo-V. Zihlukaniswe ngezigaba ezahlukene ngenxa yokwehluka kwezindinganiso zokukhiqiza kanye nezinhlobo zomkhiqizo, kodwa zombili zidlala indima ebalulekile embonini yamandla namakhemikhali. Ngezansi ukuhlaziywa okuningiliziwe komehluko kanye nokusetshenziswa kwazo.

1. Umehluko Obalulekile Phakathi kwe-T91 ne-P91

•Ifomu Lomkhiqizo kanye Nezindinganiso:

I-T91: Ihlukaniswe ngokuthi "i-Tube" noma "i-Tubing" ngaphansi kwezindinganiso ze-ASME (American Society of Mechanical Engineers). Ngokuvamile isetshenziselwa amashubhu e-boiler, amashubhu e-superheater, namashubhu okuvuselela.

I-P91: Ihlukaniswe ngokuthi "Ipayipi" ngaphansi kwezindinganiso ze-ASME. Isetshenziswa kakhulu emigqeni emikhulu yomusi, amapayipi anomfutho ophezulu anobubanzi obukhulu, kanye nama-header.

•Izidingo Zokukhiqiza:

I-T91 idinga ukunemba okuphezulu kobukhulu, ikhwalithi yobuso, kanye nokusebenza kokugoba ukuze kuhlangatshezwane nokuhlelwa kweshubhu yebhoyila okuyinkimbinkimbi.

I-P91 igxile kakhulu emandleni okuthwala umfutho odongeni olujiyile kanye nokushintshwa, okwenza ifaneleke ezingxenyeni ezinkulu zesakhiwo.

•Ukugcizelelwa Kokusebenza:

Nakuba zombili lezi zinhlobo zamakhemikhali zinokwakheka okufanayo, izakhiwo zazo ezincane kanye nezinqubo zokwelapha ukushisa ziyahlukahluka kancane. I-T91 ibeka phambili amandla okukhukhuleka okushisa okuphezulu kanye nokumelana nokugqwala kwegesi yoketshezi, kanti i-P91 igcizelela ukuqina okuphelele kanye nokuqina kwenkonzo yesikhathi eside.

2. Izinkambu Zohlelo Lokusebenza

•Imboni Yokukhiqiza Ugesi:

I-T91 isetshenziswa kakhulu ezingxenyeni zokushisa okuphezulu zama-boiler ezitshalo zamandla abucayi kakhulu nabucayi kakhulu, njenge-superheater namashubhu okuvuselela, akwazi ukusebenza isikhathi eside emazingeni okushisa afinyelela ku-620.°C.

I-P91 isetshenziswa kumapayipi amakhulu omusi, ama-header, kanye nama-valve okucindezela okuphezulu okushisa okuphezulu, okunikeza amandla amahle kakhulu okuthwala ukucindezela kwezinhlelo zokudlulisa ezibalulekile ezitshalweni zikagesi.

•Imboni Ye-Petrochemical:

Zombili lezi zinhlobo ze-alloy zisetshenziswa kuma-reactors anengcindezi ephezulu yokushisa, kuma-heat exchanger, kanye nama-cracking units, okubonisa ukumelana nezimo ezigqwalisayo njenge-hydrogen sulfide.

•Eminye Imikhakha Yezimboni:

Lokhu kufaka phakathi izinhlelo ezisizayo ezitshalweni zamandla enuzi kanye nemishini yokwelapha ukushisa okushisa okuphezulu edinga ukumelana nokushisa nokucindezela.

3. Izinto Okumelwe Uzicabangele Ngokukhetha

Ukukhetha phakathi kwe-T91 ne-P91 kuncike ezimweni ezithile zokusebenza: I-T91 ikhethwa kakhulu ngamapayipi amancane, anodonga oluncane adinga ukugoba, kuyilapho i-P91 ifaneleka kakhulu ngamapayipi amakhulu, anodonga oluqinile noma izingxenye zesakhiwo. Zombili lezi zinsimbi zidinga ukulawulwa okuqinile kwezinqubo zokushisela kanye nokwelashwa kokushisa ukuze kwandiswe izinzuzo zazo zokusebenza ezisezingeni lokushisa eliphezulu.
