ASTM A192 (ASME SA192) umuyoboro w'icyuma ni umuyoboro w'icyuma cya karuboni udafite umugozi ukoreshwa mu bidukikije birimo ubushyuhe bwinshi n'umuvuduko mwinshi, kandi ukoreshwa cyane mu byuma bishyushya n'ibihindura ubushyuhe.
Umurambararo wo hanze: 1/2″ – 7″ (12.7 mm – 177.8 mm);
Ubunini bw'urukuta: 0.085″ – 1.000″ (2.2 mm – 25.4 mm);
Izindi ngano z'imiyoboro y'icyuma nazo zishobora gutangwa uko bikenewe, mu gihe ibindi bisabwa byose bya A192 byujuje.
ASTM A192 ikorwa hakoreshejwe uburyo bunoze kandi irangizwa ishyushye cyangwa ikonje uko bikenewe;
Nanone, kumenya umuyoboro w'icyuma bigomba kugaragaza niba umuyoboro w'icyuma warangijwe ushyushye cyangwa ukonje.
Gusoza bishyushye: Bivuga inzira yo kurangiza ibipimo bya nyuma by'umuyoboro w'icyuma mu gihe gishyushye. Iyo umuyoboro w'icyuma umaze gukorwaho ubushyuhe nko gushyuha cyangwa gukururwa, ntukomeza gutunganywa ukonje. Imiyoboro y'icyuma ishyushye ifite ubukana bwiza kandi igenda neza ariko ifite ubushobozi bwo kwihanganira imiterere minini.
Irangizwa n'ubukonje: Umuyoboro w'icyuma utunganywa kugeza ku bipimo byawo bya nyuma hakoreshejwe uburyo bukonje nko gukonjesha cyangwa gukurura ubukonje ku bushyuhe bw'icyumba. Imiyoboro y'icyuma ikonje ifite ubushobozi bwo kwihanganira imiterere isobanutse neza n'ubuso bworoshye ariko ishobora kudakomera.
Imiyoboro y'icyuma ishyushye kandi idakora neza ntikenera gushyushya.
Imiyoboro y'icyuma ikozwe mu buryo bukonje itunganywa n'ubushyuhe ku bushyuhe bwa dogere selisiyusi 650 cyangwa irenga nyuma yo kuyitunganya bwa nyuma.

ASTM A192 ntiyemera kongeramo ibindi bintu mu bigize imiti.
| Imbaraga zo gukurura | Imbaraga z'umusaruro | Kurekura | Ikizamini cyo Kugorora | Ikizamini cyo Gutwika |
| umunota | umunota | muri mm 2 cyangwa 50, umunota | ||
| 47 ksi [325 MPa] | 26 ksi [180 MPa] | 35% | Reba ASTM A450, Igice cya 19 | Reba ASTM A450, Igice cya 21 |
Uretse igihe byavuzwe ukundi muri ASTM A192, ibikoresho byatanzwe hakurikijwe ibi bigomba kubahiriza ibisabwa naASTM A450/A450M.
Ubukomere bwa Rockwell: 77HRBW.
Ku miyoboro y'icyuma ifite ubugari bw'urukuta buri munsi ya 0.2" [5.1 mm].
Ubukomere bwa Brinell: 137HBW.
Ku bunini bw'urukuta rw'umuyoboro w'icyuma wa santimetero 5.1 cyangwa zirenga.
Ku bijyanye n'ibisabwa byihariye mu mikorere, reba ASTM A450, Ingingo ya 23.
· Inshuro: Buri muyoboro w'icyuma ukorerwa isuzuma ry'umuvuduko wa hydrostatic.
· Igihe: Komeza umuvuduko muto byibuze mu gihe cy'amasegonda 5.
· Agaciro k'umuvuduko w'amazi: Kabarwa hakoreshejwe formula ikurikira. Reba igice.
Ibipimo bya santimetero - Pound: P = 32000 t/D
Ibice bya SI: P = 220.6t/D
P = igitutu cy'ikizamini cya hydrostatic, psi cyangwa MPa;
t = ubugari bw'urukuta bwagenwe, muri mm cyangwa muri mm;
D = umurambararo wo hanze wagaragajwe, muri. cyangwa mm.
· Ibisubizo: Iyo nta gusohoka kw'imiyoboro, ikizamini gifatwa nk'icyatsinze.
Ubundi buryo bwo gupima amazi bushobora gukoreshwa mu gupima ibintu bidasenya.
Ariko, ibipimo ngenderwaho ntibigaragaza uburyo bwo gupima budasenya bushobora gukoreshwa.
Iyo imiyoboro ishyizwe mu muri boiler igomba guhagarara yagutse kandi ikora neza nta nkomyi cyangwa inenge zigaragara. Iyo imiyoboro ya Superheater ikoreshejwe neza igomba guhagarara imirimo yose yo gucura, gusudira no gupfunyika ikenewe kugira ngo ikoreshwe nta busembwa bugaragara.
Botop Steelni uruganda rukora imiyoboro ya karuboni ikoze mu byuma bya karuboni rwo mu Bushinwa, rukaba kandi rutanga imiyoboro y'ibyuma idafite umugozi, ruguha ibisubizo bitandukanye by'imiyoboro y'ibyuma!
Twandikireku giciro cyatanzwe n'umucuruzi w'imiyoboro y'icyuma idafite umugozi wo mu Bushinwa.
