Ibyingenzi byingenzi bya ASTM A335 P91 Ubwoko bwa 2 tubes
ASTM A335 P91 Ubwoko bwa 2 nicyuma cya chrome-moly alloy ibyuma bizwiho imbaraga zidasanzwe, kurwanya ubushyuhe, nimbaraga zo kunyerera. Byashyizwe mubikorwa nkibikurura imbaraga-byongera ferritic (CSEF) ibyuma, bigatuma biba byiza kubushyuhe bwo hejuru nubushyuhe bukabije. Ibikoresho bigenda muburyo bwihariye bwo kuvura ubushyuhe:

Ubusanzwe kuri 1050 ° C.

Gukonjesha ikirere kugeza kuri 200 ° C.

Ubushyuhe kuri 760 ° C.

Iyi nzira yongerera imbaraga imbaraga zayo nigihe kirekire, bigatuma ihitamo ryiza kubidukikije bisaba.

Ibigize ninyungu za ASTM A335 P91 Imiyoboro yicyuma
Chromium (9%): Yongera imbaraga zubushyuhe bwo hejuru, kurwanya okiside, hamwe nubukanishi.

Molybdenum (1%): Itezimbere ubuhanga, kwambara, hamwe nubushyuhe bwo hejuru.

Vanadium na Columbium / Niobium: Kongera imbaraga zo gukurura no kurwanya umunaniro ukabije.

Ibyiza bya ASTM A335 P91 Amashanyarazi
Kugabanya ubukuta bwurukuta: Emerera ibice byoroheje, kugabanya igihe cyo gusudira, nicyuma cyuzuye.

Ubuzima bwo hejuru bwumuriro mwinshi: Kugera inshuro 10 kurenza ababanjirije nka T22 cyangwa P22.

Kongera ubushyuhe bwo gukora: Kunoza imikorere mubushyuhe bwo hejuru.

Porogaramu ya ASTM A335 P91 Imiyoboro y'icyuma
P91 ikoreshwa cyane mubikorwa bisaba ibikoresho bishobora guhangana nubushyuhe bukabije nigitutu. Porogaramu zisanzwe zirimo:

Amashanyarazi: Amashanyarazi, gushyushya imirongo, hamwe nibihingwa byizunguruka.

Ibikomoka kuri peteroli: Ubushyuhe, ibikoresho byo gutunganya gaze, na serivisi za peteroli.

Sisitemu yo hejuru yubushyuhe bwo hejuru: Bikwiranye no kunama, gukubita, no gusudira.

Ibigize imiti ya ASTM A335 P91 Imiyoboro yicyuma
Ibigize imiti ya P91 byemeza imikorere yayo isumba izindi:

Carbone: 0.08% - 0,12%

Manganese: 0,30% - 0,60%

Chromium: 8.00% - 9.50%

Molybdenum: 0,85% - 1.05%

Vanadium: 0.18% - 0,25%

Azote: 0.030% - 0.070%

Ibindi bintu: Nickel, aluminium, columbium, titanium, na zirconium muburyo bugenzurwa.

Ibikoresho bya mashini
Imbaraga za Tensile: Nibura 85.000 PSI (585 MPa).

Imbaraga Zitanga: Nibura 60.000 PSI (415 MPa).

Gusudira no Kuvura Ubushyuhe ASTM A335 P91 Ibyuma
Gusudira P91 bisaba kubahiriza byimazeyo uburyo bwo kubungabunga umutungo wabwo:

Gushyushya: Ibyingenzi kugirango wirinde hydrogène iterwa no guturika.

Kugenzura ubushyuhe hagati yubushyuhe: Gukomeza ukoresheje sisitemu yo gushyushya induction igezweho.

Kuvura ubushyuhe nyuma yo gusudira (PWHT): Nibyingenzi kugirango ugere kuri microstructure yifuza kandi wirinde gutsindwa.

Welding electrode: Igomba guhuza ibikoresho byababyeyi.

Kuberiki Guhitamo Ibyuma Byuma ASTM A335 P91 Ibyuma Byuma?
Ibarura ryinshi: Ibikoresho byiza bya P91 kubyo ukeneye byose.

Ubuhanga: Itsinda ry'inararibonye ryo kukuyobora binyuze mu guhitamo ibikoresho no kubishyira mu bikorwa.

Kwiyemeza ubuziranenge: Gusa ibikoresho byiza biva mubikorwa byemewe.

Kubisabwa byose ASTM A335 P91 Ubwoko bwa 2 ibisabwa, hamagara Womic Steel uyumunsi. Itsinda ryabo ryiteguye gutanga ibisubizo birenze ibyo muteganya no gutanga ibikoresho byiza cyane mumishinga yawe.
