Umuyoboro w'icyuma udafite icyuma ni ubwoko bw'icyuma kitagira icyuma, kandi imikorere yacyo irarenze cyane iy'umuyoboro usanzwe udafite icyuma, kubera ko uyu muyoboro w'icyuma urimo Cr nyinshi, kandi n'ubushyuhe bwo hejuru, ubushyuhe buke ndetse no kurwanya ruswa ni byiza kuruta indi miyoboro idafite ibyuma. Ntagereranywa, so tubes ikoreshwa cyane muri peteroli, imiti, amashanyarazi, amashyiga nizindi nganda. Umuyoboro w'icyuma utarimo icyuma (Seamless Steel Tube) ufite igice cyuzuye, umurongo muremure w'icyuma udafite aho uzengurutse. Umuyoboro w'icyuma ufite igice cyuzuye kandi ukoreshwa cyane nk'umuyoboro wo gutwara amazi, nk'imiyoboro yo gutwara peteroli, gaze gasanzwe, gaze, amazi n'ibikoresho bimwe bikomeye. Ugereranije nicyuma gikomeye nkicyuma kizengurutse, umuyoboro wicyuma udafite icyuma ufite imbaraga zingana na torsional hamwe nuburemere bworoshye. Nicyuma cyubukungu cyicyuma kandi gikoreshwa cyane mugukora ibice byubatswe nibice bya mashini, nko gutwara peteroli. Gukora ibice byimpeta hamwe numuyoboro wicyuma udafite icyuma birashobora kunoza imikoreshereze yibikoresho, koroshya uburyo bwo gukora, kubika ibikoresho nigihe cyo gutunganya, nko kuzunguruka impeta, ama jack, nibindi, byakoreshejwe cyane mugukora imiyoboro yicyuma. Umuyoboro w'icyuma ushyizwemo kandi ni ibikoresho by'ingirakamaro ku ntwaro zitandukanye zisanzwe, kandi ingunguru, ingunguru, n'ibindi bigomba kuba bikozwe mu miyoboro y'icyuma. Mubyongeyeho, iyo igice cyimpeta gikorewe umuvuduko wimbere cyangwa hanze, imbaraga zirasa. Kubwibyo, ibyinshi bivanga ibyuma bidafite ibyuma ni imiyoboro izengurutse.
Ibyiciro:
Umuyoboro wubatswe udafite icyuma: ahanini ikoreshwa muburyo rusange nuburyo bwa mashini. Ibikoresho bihagarariye (ikirango): ibyuma bya karubone 20, 45 ibyuma; ibyuma bivangwa na Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, nibindi.
Imiyoboro y'icyuma idafite icyerekezo cyo gutanga amazi: ahanini ikoreshwa mugutanga imiyoboro y'amazi mubukorikori nibikoresho binini. Ibikoresho byerekana (amanota) ni 20, Q345, nibindi
Imiyoboro y'icyuma idafite icyerekezo cyo gutekesha ingufu ziciriritse: cyane cyane ikoreshwa mumiyoboro yo kugeza amazi mabi kandi aringaniye mumashanyarazi no mumashanyarazi. Ibikoresho bihagarariye ni 10, 20 ibyuma.
Imiyoboro y'icyuma idafite icyerekezo cyo guteka cyane. Ibikoresho bihagarariye ni 20G, 12Cr1MoVG, 15CrMoG, nibindi
Imiyoboro yicyuma idafite ibikoresho byifumbire mvaruganda: ikoreshwa cyane mubushyuhe bwo hejuru hamwe numuvuduko ukabije wamazi yibikoresho byifumbire. Ibikoresho bihagarariye ni 20, 16Mn, 12CrMo, 12Cr2Mo, nibindi
Imiyoboro idafite ibyuma yo kumena amavuta: cyane cyane ikoreshwa mubyuma, guhanahana ubushyuhe hamwe numuyoboro wogukwirakwiza mumashanyarazi. Ibikoresho bihagarariye ni 20, 12CrMo, 1Cr5Mo, 1Cr19Ni11Nb, nibindi.
Imiyoboro y'icyuma idafite icyuma cya silinderi: ikoreshwa cyane mugukora gaze zitandukanye na silindiri hydraulic. Ibikoresho byayihagarariye ni 37Mn, 34Mn2V, 35CrMo nibindi.
Imiyoboro ishyushye idafite icyuma cya hydraulic: ikoreshwa cyane mugukora hydraulic, silinderi hamwe ninkingi mumabuye yamakara, kimwe nandi mashanyarazi ya hydraulic hamwe ninkingi. Ibikoresho byayihagarariye ni 20, 45, 27SiMn, nibindi
Gukonjesha gukonje cyangwa gukonjesha gukonjesha neza ibyuma bidafite ibyuma: bikoreshwa cyane muburyo bwubukanishi, ibikoresho byo gukanda karubone, bisaba uburinganire buringaniye kandi burangije neza. Ibikoresho byayo bihagarariye ni 20, 45 ibyuma, nibindi
