Ubwiza buhebuje ASTM A335 P91 Uruganda rukora imiyoboro itagira ingano mu Bushinwa
Incamake
Iterambere ryacu rishingiye ku bikoresho byateye imbere, impano nziza kandi dukomeza gushimangira imbaraga zikoranabuhanga mu nganda zacu zo mu rwego rwo hejuru zifite ibyuma, Tugiye guhora duharanira kongera uruganda rwacu no gutanga ibicuruzwa byiza byiza hamwe n’ibiciro bikaze. Ikibazo cyangwa igitekerezo icyo aricyo cyose kirashimirwa cyane. Wibuke kudufata mu bwisanzure. Isosiyete yacu ikora ikurikiza ihame ryibikorwa by "" ubunyangamugayo, ubufatanye bwashyizweho, abantu berekeza, ubufatanye-bunguka ". Turizera ko dushobora kugirana ubucuti numucuruzi uturutse impande zose zisi
P91 ntabwo ifite imbaraga nyinshi zo kurwanya okiside hamwe nubushyuhe bwo hejuru bwo kwangirika kwangirika, ariko kandi ifite ingaruka nziza zikomeye hamwe na plastike ndende kandi ihamye kandi iramba. Iyo ubushyuhe bwa serivisi buri munsi ya 620 ℃, impungenge zayo zirenze iz'icyuma cya austenitis. Hejuru ya 550 ℃, igishushanyo mbonera gishobora kwemererwa guhangayikishwa hafi kabiri na T9 na 2.25Cr-1Mo ibyuma. Irashobora gukoreshwa nkubushyuhe bwo hejuru cyane hamwe nubushyuhe bwicyuma kugirango ubushyuhe bwurukuta rwubushyuhe bwa ≤625 ℃, umutwe wubushyuhe bwo hejuru hamwe nubushyuhe bwurukuta rwamazi ≤600 ℃, hamwe noguhindura ingufu za kirimbuzi hamwe nitanura ryamavuta ya peteroli.
Gusaba
Ikoreshwa cyane cyane mu gukora imiyoboro yo mu rwego rwohejuru ivanze ibyuma, umuyoboro uhinduranya ubushyuhe, umuyoboro mwinshi w’amavuta ya peteroli n’inganda
