ASTM A213 T12.
Ibintu byibanze bivangavanze ni 0,80-1.25% chromium na 0.44–0,65% molybdenum, ibishyira mubyuma bya chromium-molybdenum. Ikoreshwa cyane mubushyuhe bwo hejuru hamwe n’umuvuduko ukabije w’ibidukikije nka boiler, superheater, hamwe n’ubushyuhe.
Umuyoboro wa T12 ufite imbaraga zingana na 415 MPa nimbaraga ntoya ya MPa 220.
UNS yerekana iki cyiciro ni K11562.
Botop Steel numunyamwuga wizewe kandi wizewe wibikoresho byogucuruza no kugurisha byinshi mubushinwa, birashobora gutanga byihuse imishinga yawe hamwe nibyiciro bitandukanye byimiyoboro y'ibyuma, harimoT5 (K41545), T9 (K90941), T11 (K11597), T12 (K11562), T22 (K21590), naT91 (K90901).
Ibicuruzwa byacu bifite ubuziranenge bwizewe, biciro byapiganwa, kandi bishyigikira ubugenzuzi bwabandi.
Kumabwiriza cyangwa andi makuru, nyamuneka twandikire uyu munsi!
Ihinguriro n'imiterere
ASTM A213 T12 imiyoboro yicyuma igomba gukorwa nuburyo butagira ikizinga kandi igomba kuba ishyushye cyangwa ubukonje bwarangiye, nkuko byavuzwe.
Kuvura Ubushuhe
Imiyoboro yose ya T12 igomba gukorerwa ubushyuhe.
Uburyo bwemewe bwo kuvura ubushyuhe burimo full cyangwa isothermal annealing, gusanzwe no kurakara, cyangwasubcritical annealing.

Ubunini bwa ASTM A213 T12 nubunini bwurukuta mubusanzwe butangwa imbere ya diametre imbere kuva kuri mm 3.2 kugeza kuri diametre yo hanze ya mm 127, naho uburebure bwurukuta kuva kuri mm 0.4 kugeza kuri mm 12,7.
Ubundi bunini bwimiyoboro ya T12 nayo irashobora gutangwa, mugihe ibindi bisabwa byose bya ASTM A213 byujujwe.
ASTM A213 T12 ivanze ibyuma bitagira umuyonga bikoreshwa cyane cyane mubushyuhe bwo hejuru hamwe na serivise yumuvuduko mwinshi. Porogaramu zisanzwe zirimo
1. Ibihe byiza hamwe nubushuhe
Ikoreshwa mumashanyarazi ya superheater na reheater tubes ikorera munsi yubushyuhe bukabije.
Byakoreshejwe cyane nkibikoresho byo gutekesha amashanyarazi, amashanyarazi agarura imyanda, hamwe ninganda.
3. Ubushyuhe
Birakwiriye guhinduranya ubushyuhe munganda za peteroli na chimique kubera guhangana kwayo neza hamwe nubushyuhe bwumuriro.
4. Itanura hamwe nubushyuhe
Yashyizwe mubitereko bitanura, itanura, hamwe nubushyuhe bwo gutunganya aho hakenewe kurwanya okiside nimbaraga zigihe kirekire.
5. Umuyoboro w'ingutu mu mbaraga n'ibikomoka kuri peteroli
Ikoreshwa kumiyoboro yubushyuhe bwo hejuru, harimo imirongo yumurongo hamwe numurongo utwara amazi ashyushye.
