Ubushinwa bukora uruganda rwubushinwa Uruganda rudafite icyuho Icyiciro Alloy Steel Pipe Tube ASTM A335 Ubushyuhe-Kurwanya Ubushyuhe bwo mu kirere Amavuta ya peteroli yamenetse
Incamake
Twishingikirije ku mbaraga za tekiniki zikomeye kandi duhora dushiraho ikorana buhanga kugira ngo duhuze icyifuzo cy’Uruganda rukora Ubushinwa kuri ASTM A335 Ubushyuhe-Kurwanya Ubushyuhe Bwuzuye Amashanyarazi ya Alloy Steel, Dushira imbere ubuziranenge bw’abakiriya kandi kubwibyo dukurikiza ingamba zikomeye zo kugenzura ubuziranenge. Ubu dufite ibikoresho byo gupima munzu aho ibisubizo byacu bigeragezwa kuri buri kintu muburyo butandukanye bwo gutunganya. Bitewe nikoranabuhanga rigezweho, tworohereza abakiriya bacu ibikoresho byabigenewe byabigenewe. Izina ryisosiyete, buri gihe rireba ubuziranenge nkishingiro ryisosiyete, gushaka iterambere binyuze murwego rwo hejuru rwo kwizerwa, twubahiriza amahame yimicungire yubuziranenge ya ISO, dushiraho isosiyete yo mu rwego rwo hejuru na umwuka witerambere-biranga ubunyangamugayo nicyizere.
Hano haratangizwa T91 / P91 alloy ibyuma bitekesha ibyuma
1. Intangiriro yo mucyiciro
T91 / P91 nicyuma cyihanganira ubushyuhe bwa ferritic, na laboratoire yigihugu ya oak ridge mu myaka ya za 1970 yatangiye gukora ubushakashatsi niterambere, naho mu 1983 muri ASME, igihugu cyacu mu 1995 kugeza ibyuma mubyiciro bya GB 5310, ikirango nka 10 cr9mo1vnbT91 / P91 ibyuma byari 9 cr1mo (T9), hashingiwe ku byuma, ubuziranenge, ikoranabuhanga ryiza rya kristalisiyoneri, hamwe na micro alloying kandi igenzurwa no kuzunguruka no kugenzura gukonjesha, byateje imbere igisekuru gishya cy’ibyuma birwanya ubushyuhe. Icyuma gifite imiterere yuzuye yubukanishi, ubushyuhe bwo hejuru busaza nyuma yo gutuza, kandi imikorere yo gusudira hamwe nibikorwa ni byiza, bikwiranye nubushyuhe bwo hejuru bwo kugabanya ibikoresho.
