Icyuma umuyoboroIterambere ry'ikoranabuhanga ryatangijwe no kwiyongera kw'amagare, iterambere rya peteroli mu ntangiriro z'ikinyejana cya 19, amato abiri y'intambara ku isi, amashyiga, gukora indege, nyuma y'intambara ya kabiri y’amashanyarazi y’amashanyarazi, inganda bityo guteza imbere gucukura peteroli na gaze no ubwikorezi, gutwara neza inganda zicyuma mugutezimbere ubwoko, umusaruro nubwiza. Ubusanzwe umuyoboro wibyuma ujyanye nuburyo bwo guterana, ugabanijwemo umuyoboro wicyuma udafite kashe hamwe nu byuma bisudira byubwoko bubiri, ubu cyane cyane kugirango tumenye umuyoboro wicyuma.
Umuyoboro w'icyuma usudira ni uko umuyoboro w'icyuma usudira, umusaruro wacyo ni uko umuyoboro wuzuye (isahani y'icyuma n'umukandara w'icyuma) hamwe no gukwirakwiza uburyo bwo guhuza no kuzunguruka mu buryo bwifuzwa bwambukiranya ibice ndetse n'ubunini bw'igituba, n'ibindi koresha uburyo butandukanye bwo gusudira kugirango usudire kandi ubone inzira yicyuma. Ugereranije n'umuyoboro w'icyuma udafite ikidodo, umuyoboro usudira ufite ibiranga neza cyane, cyane cyane uburebure bwurukuta, ibikoresho byoroshye, umurimo muto, gukora ubudahwema mubikorwa, umusaruro woroshye, ibicuruzwa byinshi mubice hanyuma.
Igikorwa cyo gukora imiyoboro kizagabanywamo: SSAW (Spirally Submerged Arc Welding); LSAW (Welding ya Arcitudinous); amashanyarazi arwanya Welding (ERW) atatu.
I. gahunda yo guteranya umuyoboro wibyuma ni nkukurikira
● Ibikoresho bito byicyuma kizunguruka ni strip coil, insinga zo gusudira na flux.
● Mbere yo gukora umurongo nyuma yo kuringaniza, gukata, gutegura, gusukura hejuru, gutwara no gutunganya.
● Igikoresho cyo kugenzura icyuho cyakoreshejwe kugirango hemezwe ko icyuho cyo gusudira cyujuje ibisabwa byo gusudira, kandi na diameter ya pipe, impande zombi hamwe nu cyuho cya weld bigenzurwa cyane.
● Nyuma yo gukata umuyoboro umwe wicyuma, buri cyiciro cyicyuma cyumutwe wa gatatu kugirango ugenzure uburyo bwambere bwo kugenzura, kugenzura imiterere yubukorikori bwa weld, imiterere yimiti, imiterere yo gushonga, ubwiza bwicyuma cyumuringa na nyuma yubugenzuzi budahwitse, menya neza ko umuyoboro gukora inzira yujuje ibyangombwa, ishyirwa mubikorwa.
Babiri, igororotse igororotse arc gusudira umuyoboro
Umuyoboro ugororotse wuzuye arc welded umuyoboro (LSAW) mubisanzwe ufata isahani nkibikoresho, binyuze muburyo butandukanye bwo gukora, ifata impande zombi zometseho arc gusudira hamwe no kwaguka nyuma yo gusudira hamwe nubundi buryo bwo gukora umuyoboro usudira.
Ibikoresho nyamukuru ni imashini ishushanya, imashini ibanziriza, imashini ikora, imashini isudira, imashini yagura hanyuma. Hagati aho, hari UO (UOE), RB (RBE), JCO (JCOE) hanyuma. Isahani iri mubibumbano byabanje gukanda muburyo bwa U, bityo ukande muburyo bwa O, hanyuma rero imbere hamwe ninyuma yohasi arc gusudira, gusudira mubisanzwe hejuru cyangwa uburebure bwuzuye bwo kwaguka (Kwaguka) bita UOE welded pipe, ntabwo Kwaguka bita UO welded pipe. Isahani yazungurutswe Igoramye, hanyuma imbere ninyuma yohasi arc gusudira birakorwa. Nyuma yo gusudira, diameter ni RBE welded tube cyangwa RB welded tube itagutse. Isahani yaremewe muburyo bwa JcO, hanyuma nyuma yo gusudira, diameter yaguwe kugeza umuyoboro wa JCOE weld cyangwa umuyoboro wa JCO utagutse.
Ibice bitatu, bigororotse cyane byogosha umuyoboro (ERW) ni uko igiceri gishyushye nyuma yo kubumba imashini, ukoresheje ibintu byamashanyarazi hamwe ningaruka zo kuba hafi yumuvuduko mwinshi, bityo rero igituba cyumuriro kirashyuha kandi kigashonga, mugikorwa cyo gusohora roller igitutu gusudira kugirango ugere kumusaruro.
