T91uyeP91isimbi mbiri dzinoshandiswa zvakanyanya dzinopisa zvakanyanya uye dzine simba guru remartensitic dzinobva mu 9Cr-1Mo-V alloy system. Dzakarongwa zvakasiyana nekuda kwekusiyana kwemaitiro ekugadzira uye mafomu ezvigadzirwa, asi dzese dzinoita basa rakakosha muindasitiri yesimba nemakemikari. Pazasi pane ongororo yakadzama yemusiyano wavo uye mashandisirwo adzo.

1. Musiyano Mukuru Pakati peT91 neP91

•Fomu reChigadzirwa neMaitiro:

T91: Inoiswa muchikamu che "Tube" kana "Tubing" pasi pemitemo yeASME (American Society of Mechanical Engineers). Inowanzo shandiswa kumachubhu eboiler, machubhu esuperheater, uye machubhu ereheater.

P91: Yakarongwa se "Mapaipi" pasi pemitemo yeASME. Inonyanya kushandiswa mumitsetse mikuru yemhepo, mapaipi ane dhayamita hombe ane simba repamusoro, uye mumisoro.

•Zvinodiwa pakugadzira:

T91 inoda kururamisa kwakakwirira, mhando yepamusoro, uye mashandiro ekukombama kuti ikwane marongero akaomarara echubhu yeboiler.

P91 inonyanya kutarisisa kugona kwayo kupinza simba pamadziro akakora uye kugona kusundira, zvichiita kuti ive yakakodzera zvikamu zvikuru zvechivakwa.

•Kusimbiswa Kwekuita:

Kunyange zvazvo ma alloys ese ari maviri aine maumbirwo akafanana emakemikari, ma microstructures awo uye maitiro ekurapa kupisa anosiyana zvishoma. T91 inonyanya kukosha pakusimba kwekupisa kwakanyanya uye kuramba flue gas corrosion, nepo P91 ichisimbisa kusimba kwese uye kugadzikana kwenguva refu kwebasa.

2. Minda Yekushandisa

•Indasitiri yeKugadzira Magetsi:

T91 inonyanya kushandiswa muzvikamu zvinopisa zvakanyanya zvemaboiler emagetsi anonyanya kukosha uye anonyanya kukosha, akadai semachubhu emagetsi anodziya uye anodzoreredza kupisa, anokwanisa kushanda kwenguva refu patembiricha inosvika 620°C.

P91 inoshandiswa mumapaipi makuru emhepo, maheaders, uye mavharuvhu ane simba repamusoro-soro, zvichipa kugona kwakanaka kwekutakura simba remagetsi kune masisitimu ekufambisa akakosha mumafekitori emagetsi.

•Indasitiri yePetrochemical:

Ma alloys ese ari maviri anoshandiswa muma reactors ane simba rekupisa kwakanyanya, ma heat exchangers, uye ma units anotsemuka, zvichiratidza kusawirirana nemamiriro ezvinhu anoparadza akadai se hydrogen sulfide.

•Mamwe Maindasitiri:

Izvi zvinosanganisira masisitimu ekubatsira ari mumafekitori emagetsi enyukireya uye michina yekurapa kupisa inodziya zvakanyanya inoda kudzivirira kupisa nekumanikidzwa.

3. Zvaunofanira Kufunga Nezvekusarudza

Sarudzo pakati peT91 neP91 inoenderana nemamiriro chaiwo ekushanda: T91 inosarudzwa pamapombi madiki, ane dhayamita yakatetepa anoda kukotama, nepo P91 yakakodzera mapombi akatwasuka ane dhayamita hombe, ane madziro akakora kana zvikamu zvemaumbirwo. Ma alloys ese ari maviri anoda kudzora zvakanyanya maitiro ekuwelda uye ekupisa kuti awedzere kunaka kwawo pakushanda zvakanyanya pakupisa kwakanyanya.
