ASTM A213 T9, izwi kandi nka ASME SA213 T9, ni igikoresho gito gikoreshwa mu gupimaumuyoboro w'icyuma udakoraikoreshwa mu byuma bishyushya, ibishyushya cyane, n'ibihindura ubushyuhe.
T9 ni aloyi ya chromium-molybdenum irimo chromium 8.00–10.00% na molybdenum 0.90–1.10%. Ifite imbaraga nkeya zo gukurura za 415 MPa n'imbaraga nkeya zo gutanga 205 MPa. Ifite imbaraga nziza cyane zo gushyuha cyane, kurwanya oxidation, no kurwanya gukurura, T9 ikora neza mu gihe ikora mu bushyuhe bwinshi n'umuvuduko mwinshi.
Nk'umucuruzi w'umwuga w'imiyoboro y'ibyuma bya alloy n'umucuruzi mu bucuruzi bwinshi mu Bushinwa,Botop Steelishobora gutanga vuba imiyoboro myinshi y'icyuma ya T9 ku mishinga yawe, ifite ubuziranenge bwizewe n'ibiciro bishimishije.
Igicuruzwa cyatanzwe kuri ASTM A213 kigomba kubahiriza ibisabwa mu bisobanuro bya ASTM A1016, harimo n'ibindi bisabwa by'inyongera byagaragajwe mu itegeko ryo kugura.
ASTM A1016: Ibisobanuro Bisanzwe ku Bisabwa Rusange ku Cyuma cya Ferritic Alloy, Icyuma cya Austenitic Alloy, n'Imiyoboro y'Icyuma Kidafunze
Uruganda n'imiterere yarwo
Imiyoboro y'icyuma ya ASTM A213 T9 igomba gukorwa hakoreshejwe uburyo butagira umugozi kandi igomba kuba ishyushye cyangwa ikonje, nk'uko byavuzwe.
Uburyo bwo kuvura ubushyuhe
Imiyoboro y'icyuma ya T9 igomba kongera gushyushya kugira ngo ikoreshwe mu bushyuhe hakurikijwe uburyo bukurikira, kandi ikoreshwe mu buryo butandukanye kandi hiyongereyeho gushyushya kugira ngo ikoreshwe mu bushyuhe.

Ibisabwa ku miterere y’imashini ntibireba imiyoboro iri munsi ya santimetero 3.2 z’umurambararo w’imbere cyangwa ifite ubugari burenze santimetero 0.015 z’ubugari.
Ingano y'ingano
Ingano z'imiyoboro ya ASTM A213 T9 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 T9 nazo zishobora gutangwa, mu gihe ibindi bisabwa byose bya ASTM A213 byujuje.
Ubwinshi bw'urukuta bushobora kwihanganira
Ubwinshi bw'urukuta bugomba kugenwa hashingiwe ku bintu bibiri bikurikira: niba urutonde rwagenwe hakurikijwe ubunini bw'urukuta buke cyangwa ubunini bw'urukuta mpuzandengo.

Iyo ishyizwe mu gikoresho cyo gukaraba cyangwa mu gikoresho cyo gukaraba, imiyoboro igomba kwihanganira kwaguka no gukurura imitako nta nkomyi cyangwa inenge zigaragara. Iyo imiyoboro ya Superheater ikozwe neza, igomba kwihanganira imirimo yose yo gukaraba, gusudira no gukaraba ikenewe kugira ngo ikoreshwe nta busembwa bugaragara.
ASTM A213 T9 ni umuyoboro udafite umugozi wa Cr-Mo uzwiho gukomera cyane mu bushyuhe bwinshi, kurwanya gukurura no kurwanya ingese mu bushyuhe bwinshi. Ukoreshwa cyane mu bidukikije birimo ubushyuhe bwinshi n'umuvuduko mwinshi. Ikoreshwa mu buryo busanzwe harimo:
Ikoreshwa mu miyoboro y'umwuka ishyuha cyane, ahantu hashyushya ibyuma, aho hasi hashyirwa amashanyarazi, aho hejuru hashyirwa amashanyarazi, n'ahandi hantu hakora mu bushyuhe n'umuvuduko mwinshi uhoraho.
2. Imiyoboro y'amashanyarazi n'iy'amashanyarazi
Ni byiza cyane mu gushyushya cyane no kongera gushyushya ibice bitewe nuko birwanya cyane gukurura no gukora neza mu bushyuhe bwinshi.
3. Imiyoboro ihindura ubushyuhe
Ikoreshwa mu nganda zitunganya ubushyuhe, inganda zikora imiti, n'inganda zitanga amashanyarazi kugira ngo zikoreshwe mu bushyuhe bwinshi.
4. Inganda za peteroli
Ikoreshwa mu miyoboro ishyushya cyane, imiyoboro ya hydrotreater reactor, imiyoboro y'itanura, n'ibindi bikoresho bishyushya cyane.
5. Inganda zitanga amashanyarazi
Ikwiriye imiyoboro y'amashanyarazi ikoresha ingufu nyinshi n'ubushyuhe bwinshi mu nganda zikoresha amakara, inganda zikoresha imyanda mu gutanga ingufu, ndetse n'inganda zikoresha biomass.
6. Amatanura y'inganda
Ikoreshwa mu miyoboro irabagirana n'imiyoboro y'itanura isaba ubudahangarwa ku bushyuhe bwinshi.
