Imiyoboro isudira ya spiral Kumurongo wa gazi isanzwe
Imiyoboro isudirani ngombwa mu nganda, cyane cyane mu iyubakwa ry'imiyoboro ya peteroli na gaze.Ibisobanuro byabo bigaragarira mumurambararo winyuma hamwe nubunini bwurukuta, byerekana guhuza kwabo no guhuza nibisabwa bitandukanye.

Uburyo bwo gukora imiyoboro isudira izengurutswe ikubiyemo gukoresha tekinoroji yo gusudira imiyoboro igezweho, itanga imiyoboro imwe cyangwa ibiri.Izi nzira zo gusudira zitanga igihe kirekire kandi cyizewe cyumuyoboro, ushoboye guhangana ningutu zaumurongo wa gaze gasanzwekwanduza.
Ku ruganda rwacu rutanga umusaruro, turemeza ko imiyoboro yacu isudira izengurutswe ikizamini cyujuje ubuziranenge kugirango tumenye neza imikorere yabo.Ni ngombwa ko umuyoboro usudira wujuje amabwiriza yo gupima hydraulic, imbaraga zingana hamwe nubukonje bukonje.
Imiyoboro yacu yo gusudira izengurutswe yagenewe kurenga ibipimo byinganda kandi byujuje ibisabwa cyane muri sisitemu yohereza imiyoboro ya gaze gasanzwe.Byashizweho kugirango bihangane n’ibidukikije bitandukanye, byemeza igihe kirekire n’umutekano muri porogaramu iyo ari yo yose.
Gukoresha imiyoboro isudira izunguruka muri sisitemu yo gutwara gazi ya gazi yo munsi y'ubutaka itanga uburyo bwiza kandi bunoze bwo gutwara gaze gasanzwe.Kuramba kwubwubatsi bwizengurutswe butanga gaze kandi bigabanya ibyago byo kumeneka cyangwa kwangirika mugihe, bigaha amahoro mumitima kubakoresha ndetse nabakoresha amaherezo.
Twiyemeje guha abakiriya bacu ibicuruzwa byujuje ubuziranenge, kandi imiyoboro yacu yo gusudira izenguruka ni ikimenyetso cyerekana ko twiyemeje kuba indashyikirwa mu nganda.Dushyira imbere igihe kirekire, imikorere n'umutekano by'ibicuruzwa byacu, tukareba ko byujuje kandi birenze ibisabwa bikenewe muri sisitemu yohereza gazi ya gazi yo munsi y'ubutaka.
Muri make, imiyoboro yacu yo gusudira izenguruka ni ikintu cy'ingenzi mu kubaka no gufata neza uburyo bwo gutwara abantu ku gasozi gasanzwe.Hamwe nubwubatsi buhebuje, kubahiriza amahame yinganda, no kwiyemeza kutajegajega ubuziranenge, umuyoboro wacu wo gusudira ni mwiza kumushinga uwo ariwo wose wohereza gazi.Umufatanyabikorwa natwe gutanga umuyoboro mwiza wo gusudira weld kugirango umuyoboro wawe wa gazi ukenera.
