Uburyo bwombi bwo kurwanya amashanyarazi bwasuditswe (ERW) hamwe nuburyo bwo gukora ibyuma bidafite icyuma (SMLS) bwakoreshejwe mumyaka mirongo; igihe, uburyo bukoreshwa mukubyara buriwese bwateye imbere. Ninde uruta uwundi?
1. Gukora imiyoboro isudira
Umuyoboro wo gusudira utangira nkurubaho rurerure, rukomatanye rwicyuma bita skelp. Skelp yaciwe kuburebure bwifuzwa, bivamo urupapuro ruringaniye. Ubugari bwurwo rupapuro rugufi ruzahinduka umuyoboro uzenguruka hanze, agaciro gashobora gukoreshwa mukubara amaherezo ya diameter.
Amabati y'urukiramende agaburirwa binyuze mumashini izunguruka izenguruka impande ndende hejuru yundi, ikora silinderi. Mubikorwa bya ERW, umuyagankuba mwinshi w'amashanyarazi unyuzwa hagati yimpande, bigatuma ushonga hamwe.
Akarusho k'umuyoboro wa ERW nuko nta byuma bya fusion bikoreshwa kandi ikidodo cyo gusudira ntigishobora kuboneka cyangwa kumva. Ibyo birwanya kurwanya gusudira kabiri arc gusudira (DSAW), igasiga inyuma isaro igaragara neza igomba guhita ikurwaho bitewe nibisabwa.
Ubuhanga bwo gukora imiyoboro yo gusudira bwateye imbere mu myaka yashize. Ahari iterambere ryingenzi ryabaye ihinduka ryumuvuduko mwinshi w'amashanyarazi yo gusudira. Mbere ya za 1970, umuyoboro muke wakoreshejwe. Imyenda isudira ikozwe muri ERW yumurongo muke wasangaga ishobora kwangirika no kunanirwa.
Ubwoko bwinshi bwo gusudira busaba kuvura ubushyuhe nyuma yo gukora.
2. Gukora umuyoboro udafite kashe
Imiyoboro idafite icyerekezo itangira nkigikoresho gikomeye cya silindrike yicyuma cyitwa bilet. Mugihe bikiri bishyushye, bilet zacishijwe hagati hamwe na mandel. Intambwe ikurikira ni ukuzunguruka no kurambura bilet. Inyemezabuguzi irazunguruka neza kandi irambuye kugeza yujuje uburebure, diameter n'ubugari bw'urukuta nkuko byagenwe na gahunda y'abakiriya.
Ubwoko bumwebumwe butagira umuyoboro burakomera nkuko byakozwe, bityo kuvura ubushyuhe nyuma yo gukora ntibisabwa. Abandi bakeneye kuvura ubushyuhe. Menyesha ibisobanuro byubwoko butagira umuyoboro utekereza kugirango umenye niba bizakenera kuvura ubushyuhe.
3. Ibitekerezo byamateka kandi ukoreshe imanza zo gusudira hamwe nicyuma kidafite icyuma
ERW hamwe nu byuma bitagira ibyuma bibaho nkubundi buryo muri iki gihe ahanini bitewe n imyumvire yamateka.
Muri rusange, umuyoboro wasuditswe wabonaga ufite intege nke kubera ko wasangaga icyuma gisudira. Umuyoboro udafite ikinyabupfura wabuze iyi nenge igaragara kandi yafatwaga nkumutekano. Nubwo ari ukuri ko umuyoboro usudira urimo ikidodo kigira intege nke mu buryo bw'igitekerezo, tekiniki zo gukora hamwe n’ubuziranenge bw’ubuziranenge buriwese yateye imbere ku buryo umuyoboro usudira uzakora uko ubishaka iyo kwihanganira bitarenze. Nubwo inyungu zigaragara zisobanutse neza, kunenga imiyoboro idafite icyerekezo ni uko inzira yo kuzunguruka no kurambura itanga umubyimba wurukuta rudahuye ugereranije nuburinganire bwuzuye bwamabati yagenewe gusudira.
Ibipimo nganda bigenga gukora no gutondeka ERW hamwe nu muyoboro wicyuma utagira ikizinga biracyagaragaza iyo myumvire. Kurugero, imiyoboro idafite icyerekezo irakenewe kubintu byinshi byumuvuduko mwinshi, ubushyuhe bwo hejuru mubikomoka kuri peteroli na gaze, kubyara amashanyarazi ninganda zimiti. Imiyoboro isudira (muri rusange ihendutse kubyara umusaruro kandi iraboneka cyane) isobanurwa mu nganda zose mugihe ubushyuhe, igitutu nibindi bihinduka bya serivisi bitarenze ibipimo byavuzwe mubisanzwe.
Mubikorwa byubaka, nta tandukaniro mubikorwa hagati ya ERW numuyoboro wicyuma udafite kashe. Mugihe byombi bishobora gusobanurwa muburyo bumwe, ntabwo byumvikana gusobanura neza mugihe umuyoboro uhendutse wo gusudira ukora neza.
4. Utwereke spes yawe, saba amagambo hanyuma ubone umuyoboro wawe vuba
Itsinda rya Jindalai Steel Group rigumaho ibintu byose hamwe nibikoresho byiza byo gusudira ibyuma bidasudira kandi bidafite kashe mu nganda. Twakuye ibicuruzwa byacu mu ruganda ruzengurutse Ubushinwa, twemeza ko abaguzi babona umuyoboro ukenewe vuba hatitawe ku mategeko abigenga.
Jindalai irashobora kugufasha kumenya uburyo bwo gutanga amasoko kuva itangira kugeza irangiye kugirango ubone ibyo ukeneye vuba bishoboka mugihe cyo kugura. Niba kugura imiyoboro iri mugihe cya vuba, saba amagambo. Tuzaguha kimwe kiguha ibicuruzwa ukeneye byihuse.
