T91leP91ke litšepe tse peli tse sa hloekang tsa martensitic tse sebelisoang haholo tse nang le mocheso o phahameng, tse matla haholo tse nkiloeng tsamaisong ea motsoako oa 9Cr-1Mo-V. Li arotsoe ka lihlopha tse fapaneng ka lebaka la mefuta e fapaneng ea litekanyetso tsa tlhahiso le mefuta ea lihlahisoa, leha ho le joalo ka bobeli li phetha karolo ea bohlokoa indastering ea matla le ea lik'hemik'hale. Ka tlase ke tlhahlobo e qaqileng ea liphapang le lits'ebetso tsa tsona.

1. Liphapang tsa Bohlokoa Pakeng tsa T91 le P91

•Foromo le Maemo a Sehlahisoa:

T91: E hlophisitsoe e le "Tube" kapa "Tubing" tlasa maemo a ASME (Mokhatlo oa Amerika oa Baenjiniere ba Mechanical). Hangata e sebelisoa bakeng sa liphaephe tsa boiler, liphaephe tsa superheater, le liphaephe tsa reheater.

P91: E thathamisitsoe e le "Pipe" tlasa maemo a ASME. E sebediswa haholo-holo meleng e meholo ya mouoane, diphaephe tse nang le kgatello e phahameng tse bophara bo boholo, le dihlooho.

•Litlhoko tsa Tlhahiso:

T91 e hloka ho nepahala ho hoholo ha boholo, boleng ba bokaholimo, le ts'ebetso ea ho kobeha ho amohela litlhophiso tse rarahaneng tsa tube ea boiler.

P91 e shebane haholo le bokgoni ba ho jara kgatello maboteng a teteaneng le ho kgona ho weldwa, e leng se etsang hore e lokele dikarolo tse kgolo tsa meaho.

•Khatiso ea Tshebetso:

Leha di-alloy ka bobedi di na le metswako e tshwanang ya dikhemikhale, dibopeho tsa tsona tse nyane le mekgwa ya kalafo ya mocheso di fapana hanyane. T91 e beha pele matla a ho kgephoha ha mocheso o phahameng le ho hanyetsa ho bola ha kgase ya flue, athe P91 e totobatsa ho tiya ka kakaretso le botsitso ba tshebeletso ya nako e telele.

2. Masimo a Kopo

•Indasteri ea Phepelo ea Motlakase:

T91 e sebelisoa haholo-holo likarolong tse nang le mocheso o phahameng tsa liboiler tsa motlakase tse nang le ts'ebetso e phahameng le tse nang le ts'ebetso e phahameng haholo, joalo ka liphaephe tsa motlakase tse nang le ts'ebetso e phahameng le tse nang le ts'ebetso e phahameng haholo, tse khonang ho sebetsa nako e telele mochesong o fihlang ho 620.°C.

P91 e sebediswa diphaepheng tse kgolo tsa mouoane, di-header, le di-valve tse nang le kgatello e phahameng ya mocheso o phahameng, e fanang ka bokgoni bo botle ba ho jara kgatello bakeng sa ditsamaiso tsa bohlokwa tsa phetiso dipolanteng tsa motlakase.

•Indasteri ea Petrochemical:

Li-alloy tsena ka bobeli li sebelisoa li-reactor tse nang le khatello e phahameng ea mocheso o phahameng, li-heat exchanger, le li-unit tsa ho petsoha, tse bontšang ho hanyetsa libaka tse senyang joalo ka hydrogen sulfide.

•Makala a Mang a Liindasteri:

Tsena di kenyeletsa ditsamaiso tse thusang dipolanteng tsa matla a nyutlelie le disebediswa tsa kalafo ya mocheso o phahameng tse hlokang ho hanelwa ke mocheso le kgatello.

3. Lintho Tse Lokelang ho Etsoa ka Khetho

Khetho pakeng tsa T91 le P91 e ipapisitse le maemo a itseng a mosebetsi: T91 e kgethwa bakeng sa diphaephe tse bophara bo bonyenyane, tse nang le mabota a masesaane tse hlokang ho kobeha, ha P91 e loketse haholoanyane bakeng sa diphaephe tse otlolohileng tse nang le mabota a maholo, tse teteaneng kapa dikarolo tsa sebopeho. Di-alloy ka bobedi di hloka taolo e tiileng hodima ditshebetso tsa ho tjheseletsa le tsa kalafo ya mocheso ho eketsa melemo ya tsona ya tshebetso ya mocheso o phahameng.
