ASTM A213 T12(ASME SA213 T12) ni umuyoboro w'icyuma udakora cyane wagenewe serivisi zishyushye cyane.
Ibintu byayo by'ingenzi bivangavanze ni 0.80–1.25% bya chromium na 0.44–0.65% bya molybdenum, ibi bikaba ari icyuma cya chromium-molybdenum alloy. Ikoreshwa cyane mu bidukikije birimo ubushyuhe bwinshi n'umuvuduko mwinshi nko muri boilers, superheaters, na thermochanges.
Umuyoboro wa T12 ufite imbaraga nkeya zo gukurura za MPa 415 n'imbaraga nkeya zo gutanga umusaruro za MPa 220.
Icyiciro cya UNS kuri iki cyiciro ni K11562.
Botop Steel ni umucuruzi w’umwuga kandi wizewe w’imiyoboro y’ibyuma bya alloy mu Bushinwa, ushobora guha imishinga yawe vuba imiyoboro y’ibyuma by’ubwoko butandukanye, harimoT5 (K41545), T9 (K90941), T11 (K11597), T12 (K11562), T22 (K21590), naT91 (K90901).
Ibicuruzwa byacu bifite ubuziranenge bwizewe, igiciro cyabyo kiri mu irushanwa, kandi bishyigikira igenzura ry’abandi.
Ku byo wategetse cyangwa ibindi bisobanuro, twandikire uyu munsi!
Uruganda n'imiterere yarwo
Imiyoboro y'icyuma ya ASTM A213 T12 igomba gukorwa hakoreshejwe uburyo butagira umugozi kandi igomba kuba ishyushye cyangwa ikonje, nk'uko byavuzwe.
Uburyo bwo kuvura ubushyuhe
Imiyoboro yose y'icyuma ya T12 igomba gushyuha.
Uburyo bwemewe bwo kuvura ubushyuhe burimogufungana kw'amazi mu buryo butuje cyangwa butagira ubushyuhe, kuvugurura no gukabyacyangwagufunga ibintu mu buryo buciriritse.

Uburyo bwo gupima bugomba gukorwa hakurikijwe ibisabwa n'Ingingo ya 25 na 26 ya ASTM A1016.
Ingano z'imiyoboro ya ASTM A213 T12 n'ubugari bw'inkuta akenshi biba bifite umurambararo w'imbere uri hagati ya mm 3.2 na mm 127, naho umurambararo w'inkuta uri hagati ya mm 0.4 na mm 12.7.
Izindi ngano z'imiyoboro y'icyuma ya T12 nazo zishobora gutangwa, mu gihe ibindi bisabwa byose bya ASTM A213 byujuje.
Imiyoboro y'icyuma idafite umugozi ya ASTM A213 T12 ikoreshwa cyane cyane mu bushyuhe bwinshi n'ubushyuhe bwinshi. Imikoreshereze isanzwe irimo
1. Ibishyushya cyane n'ibishyushya bishya
Ikoreshwa mu nganda zitanga amashanyarazi ku miyoboro ishyushya cyane n'iy'amashanyarazi ikora mu gihe cy'ubushyuhe n'umuvuduko mwinshi.
Ikoreshwa cyane nk'imiyoboro ya boiler mu mashanyarazi y'ubushyuhe, mu byuma bigarura ubushyuhe n'imyanda, no mu byuma bitanga ubushyuhe mu nganda.
3. Ibikoresho byo guhindura ubushyuhe
Ikwiriye imiyoboro ihindura ubushyuhe mu nganda zikora peteroli na shimi kubera ko idapfa gucika kandi ikagira ubushyuhe burambye.
4. Imiyoboro y'itanura n'imashini zishyushya
Ishyirwa mu byuma bitunganya ifuru, imiyoboro y'ubushyuhe, n'ibishyushya aho bisaba imbaraga zo kurwanya ogisijeni n'igihe kirekire.
5. Imiyoboro y'umuvuduko mu nganda zitanga ingufu n'ibikomoka kuri peteroli
Ikoreshwa mu miyoboro ikoresha ubushyuhe bwinshi, harimo imiyoboro y'umwuka n'imiyoboro itwara amazi ashyushye.
