Iimpawu eziphambili zeetyhubhu ze-ASTM A335 P91 Type 2
Uhlobo lwe-ASTM A335 P91 2 yintsimbi ye-chrome-moly alloy eyaziwa ngamandla ayo angaqhelekanga, ukumelana nobushushu, kunye namandla okuqhekeka. Ihlelwe njengentsimbi ye-creep strength-enhanced ferritic (CSEF), okwenza ukuba ilungele ukusetyenziswa kobushushu obuphezulu kunye noxinzelelo oluphezulu. Le nto idlula kwinkqubo ethile yonyango lobushushu:

Ubushushu buhlala bukwi-1050°C.

Ukupholisa umoya ukuya kuthi ga kwi-200°C.

Ukufudumala kwi-760 °C.

Le nkqubo iphucula amandla ayo okuhambahamba kunye nokuqina kwayo, nto leyo eyenza ukuba ibe lolona khetho lubalaseleyo kwiindawo ezifuna amandla amaninzi.

Ukwakheka kunye neenzuzo zeetyhubhu zentsimbi ze-ASTM A335 P91
I-Chromium (9%): Yomeleza amandla obushushu obuphezulu, ukumelana ne-oxidation, kunye neempawu zoomatshini.

I-Molybdenum (1%): Iphucula ukuthamba, ukumelana nokuguguleka, kunye namandla okurhubuluza kumaqondo obushushu aphezulu.

I-Vanadium kunye neColumbium/Niobium: Yonyusa amandla okuhambahamba kunye nokumelana nokudinwa kubushushu.

Ubomi obuphezulu bokudinwa kubushushu: Kufikelela kwizihlandlo ezili-10 ngcono kunezo zangaphambili ezifana ne-T22 okanye i-P22.

Ukunyuka kwamaqondo obushushu okusebenza: Kuphucula ukusebenza kakuhle kwizicelo ezisebenzisa amaqondo obushushu aphezulu.

Ukusetyenziswa kweetyhubhu zentsimbi ze-ASTM A335 P91
I-P91 isetyenziswa kakhulu kumashishini afuna izinto ezikwaziyo ukumelana nobushushu obugqithisileyo kunye noxinzelelo. Izicelo eziqhelekileyo ziquka:

Ukuveliswa kombane: Iibhoyila, iintambo zokufudumeza kwakhona, kunye nezityalo zomjikelo odibeneyo.

Izityalo zePetrochemical: Izifudumezi, izixhobo zokucubungula igesi, kunye neenkonzo zamasimi eoyile.

Iinkqubo zokufaka imibhobho ezinobushushu obuphezulu: Zifanelekile kwimisebenzi yokugoba, yokuflanga, kunye neyokuwelda.

Ukwakheka kweeKhemikhali zeetyhubhu zeNsimbi ze-ASTM A335 P91
Ukwakheka kweekhemikhali ze-P91 kuqinisekisa ukusebenza kwayo okuphezulu:

Ikhabhoni: 0.08% – 0.12%

IManganese: 0.30% – 0.60%

I-Chromium: 8.00% – 9.50%

I-Vanadium: 0.18% – 0.25%

I-nitrogen: 0.030% – 0.070%

Ezinye izinto: I-nickel, i-aluminium, i-columbium, i-titanium, kunye ne-zirconium ngobuninzi obulawulwayo.

Iipropati zoomatshini
Amandla okuThamba: Ubuncinane yi-85,000 PSI (585 MPa).

Amandla okuvelisa: Ubuncinane yi-60,000 PSI (415 MPa).

Iityhubhu zentsimbi ze-ASTM A335 P91 zokuWelda kunye noNyango lobushushu
Ukuwelda i-P91 kufuna ukuthotyelwa ngokungqongqo kweenkqubo zokugcina iimpawu zayo:

Ukufudumeza: Kubalulekile ukuthintela ukuqhekeka okubangelwa yi-hydrogen.

Ulawulo lobushushu phakathi kwee-pass: Lugcinwa lusetyenziswa kwiinkqubo zokufudumeza zanamhlanje.

Unyango lobushushu emva kokuwelda (PWHT): Kubalulekile ukufezekisa isakhiwo esifunekayo kunye nokuthintela ukungaphumeleli.
