    Umuyoboro w'icyuma ushongeshejwe ku buryo bw'umwuka ukoreshwa mu miyoboro ya peteroli na gaze

    Umuyoboro w'icyuma ushongeshejwe ku buryo bw'umwuka w'imiyoboro ya peteroli na gaze Ishusho yagaragajwe
    • Umuyoboro w'icyuma ushongeshejwe ku buryo bw'umwuka ukoreshwa mu miyoboro ya peteroli na gaze

    Ibisobanuro bigufi:

    Mu nzego z’ubwubatsi n’ubwubatsi zihora zitera imbere, iterambere mu ikoranabuhanga rikomeje gusobanura uburyo imishinga ishyirwa mu bikorwa. Kimwe mu bishya bitangaje ni umuyoboro w’icyuma ukozwe mu buryo bwa spiral welded. Umuyoboro ufite imigozi ku buso bwawo kandi ukorwa no kugonga imirongo y’icyuma mu ruziga hanyuma ukayisudira, bikazana imbaraga zidasanzwe, kuramba no gukora ibintu bitandukanye mu buryo bwo gusudira imiyoboro. Iyi nyigo y’ibicuruzwa igamije kwerekana imiterere y’ingenzi y’umuyoboro ukozwe mu buryo bwa spiral welded no kugaragaza uruhare rwawo mu guhindura imikorere mu nganda za peteroli na gaze.

    Ibisobanuro by'igicuruzwa:

    Imiyoboro y'icyuma ivanze n'uruziga, bitewe n'imiterere yazo, zitanga inyungu nyinshi zitandukanye ugereranyije n'uburyo busanzwe bwo gukoresha imiyoboro. Uburyo bwayo bwihariye bwo kuyikora butuma ihorana ubugari buhamye mu burebure bwayo bwose, bigatuma idashobora guhangana n'igitutu cy'imbere n'inyuma. Uku gukomera gutuma imiyoboro ikoreshwa mu buryo bw'umwuka ihuza ibyuma n'amazi iba myiza cyane mu bijyanye no kohereza peteroli na gaze aho umutekano n'ubwizerwe ari byo by'ingenzi.

    Ikoranabuhanga ryo gusudira rikoreshwa mu gukora kwaryo ritanga ubushobozi bwo koroshya no guhuza ibintu, rituma umuyoboro ubasha kwihanganira imimerere mibi cyane nko ubushyuhe bwinshi, itandukaniro ry’umuvuduko w’amazi n’ibiza. Byongeye kandi, iyi miterere mishya yongera ingese no kudashira, bifasha kongera igihe cyo kuyikoresha no kugabanya ikiguzi cyo kuyisana.

    Byongeye kandi, guhuza umuyoboro w’amazi uhuza uruziga bituma habaho imikorere myiza idacika. Kubwibyo, imiyoboro ihuza uruziga itanga imiyoboro yizewe yo gutwara peteroli na gaze, bigabanya ibyago byo kuva amazi n’ibyago ku bidukikije. Ibi, hamwe n’imikorere yayo myiza y’amazi n’imikorere yayo myiza y’amazi, bituma iba nziza ku bigo bitanga ingufu bishakisha ibisubizo byizewe kandi birambye.

    Umuyoboro wa Gazi wo munsi y'ubutaka

    Uburyo bwo gukora imiyoboro ikoze mu buryo bworoshye ntabwo ari ugutwara peteroli na gaze gusa. Imiterere yayo ikomeye n'imiterere yayo myiza bituma ikoreshwa mu bikorwa bitandukanye, harimo amazi, imiyoboro y'amazi, ndetse n'imishinga y'ubwubatsi. Yaba ikoreshwa mu gutwara amazi cyangwa nk'inyubako zishyigikira, imiyoboro y'icyuma ikoze mu buryo bworoshye ni byiza mu gutanga ibisubizo byizewe kandi bihendutse.

    Gutangiza imiyoboro y'icyuma ikoze mu buryo bw'uruziga byanogeje cyane uburyo bwo gusudira imiyoboro, byoroshya inzira kandi bigabanya igihe cyose cy'umushinga. Gushyiraho byoroshye, hamwe n'uburemere buhanitse, bituma inzira yo kubaka irushaho kuba nziza kandi ikora neza. Ibi bivuze kuzigama amafaranga menshi mu kazi, ibikoresho bikenewe n'amafaranga yo gucunga umushinga, ariko bikanatuma habaho ireme ryiza kandi rirambye.

    Mu gusoza:

    Muri make, imiyoboro ikoreshwa mu gusudira imiyoboro yahinduye urwego rw'imiyoboro, cyane cyane mu nganda za peteroli na gaze. Ihuriro ryayo rihamye ry'imbaraga, kuramba, imikorere myiza no kugabanya ikiguzi rituma iba nziza ku bigo bitanga ibisubizo byizewe. Bitewe n'umuvuduko mwinshi, ingese no kudasohoka, imiyoboro y'ibyuma ikoreshwa mu gusudira imiyoboro ...
