T91ndiP91ndi zitsulo ziwiri zosapanga dzimbiri za martensitic zotentha kwambiri komanso zolimba kwambiri zomwe zimachokera ku dongosolo la alloy la 9Cr-1Mo-V. Zili m'magulu osiyanasiyana chifukwa cha kusiyana kwa miyezo yopangira ndi mitundu ya zinthu, komabe zonse zimagwira ntchito yofunika kwambiri m'mafakitale amphamvu ndi mankhwala. Pansipa pali kusanthula mwatsatanetsatane kwa kusiyana kwawo ndi momwe amagwiritsidwira ntchito.

1. Kusiyana Kwakukulu Pakati pa T91 ndi P91

•Fomu Yogulitsa ndi Miyezo:

T91: Yolembedwa kuti "Tube" kapena "Tubing" motsatira miyezo ya ASME (American Society of Mechanical Engineers). Nthawi zambiri imagwiritsidwa ntchito pa machubu a boiler, machubu a superheater, ndi machubu obwezeretsanso kutentha.

P91: Yolembedwa kuti "Chitoliro" motsatira miyezo ya ASME. Imagwiritsidwa ntchito makamaka m'mizere ikuluikulu ya nthunzi, mapaipi amphamvu kwambiri okhala ndi mainchesi akuluakulu, ndi m'makutu.

•Zofunikira pa Kupanga:

T91 imafuna kulondola kwapamwamba, mtundu wa pamwamba, ndi magwiridwe antchito opindika kuti igwirizane ndi makonzedwe ovuta a chubu cha boiler.

P91 imayang'ana kwambiri pa mphamvu yonyamula mphamvu ya khoma lokhuthala komanso kuthekera kowotcherera, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pazinthu zazikulu za kapangidwe kake.

•Kutsindika kwa Magwiridwe Antchito:

Ngakhale kuti ma alloy onsewa ali ndi mankhwala ofanana, kapangidwe kake kakang'ono ndi njira zochizira kutentha zimasiyana pang'ono. T91 imayang'ana kwambiri mphamvu ya kutentha kwambiri komanso kukana dzimbiri la mpweya wotuluka m'madzi, pomwe P91 imayang'ana kwambiri kulimba konse komanso kukhazikika kwa ntchito kwa nthawi yayitali.

2. Minda Yogwiritsira Ntchito

•Makampani Opanga Mphamvu:

T91 imagwiritsidwa ntchito makamaka mu zigawo zotentha kwambiri za ma boiler amagetsi ofunikira kwambiri komanso ofunikira kwambiri, monga machubu otenthetsera ndi otenthetsera, omwe amatha kugwira ntchito nthawi yayitali kutentha mpaka madigiri 620.°C.

P91 imagwiritsidwa ntchito m'mapaipi akuluakulu a nthunzi, ma header, ndi ma valve okwera kwambiri otentha kwambiri, zomwe zimapereka mphamvu yabwino kwambiri yonyamula kupanikizika kwa makina ofunikira kwambiri m'mafakitale amagetsi.

•Makampani Opanga Mafuta:

Ma alloy onsewa amagwiritsidwa ntchito mu ma reactors okwera kwambiri, ma heat exchanger, ndi ma cracking units, zomwe zimasonyeza kukana ku malo owononga monga hydrogen sulfide.

•Magawo Ena a Mafakitale:

Izi zikuphatikizapo machitidwe othandizira m'mafakitale amagetsi a nyukiliya ndi zida zochizira kutentha kwambiri zomwe zimafuna kukana kutentha ndi kupanikizika.

3. Zoyenera Kuganizira Posankha

Kusankha pakati pa T91 ndi P91 kumadalira mikhalidwe yeniyeni yogwirira ntchito: T91 ndi yabwino kwambiri pa mapaipi ang'onoang'ono, okhala ndi makoma owonda omwe amafuna kupindika, pomwe P91 ndi yoyenera kwambiri pa mapaipi olunjika okhala ndi makoma akuluakulu, okhuthala kapena zigawo zina za kapangidwe kake. Ma alloy onsewa amafunika kuwongolera mwamphamvu njira zowotcherera ndi zotenthetsera kutentha kuti akwaniritse bwino ntchito yawo yotentha kwambiri.
