    Umuyoboro wo mu rwego rwo hejuru

    Umuyoboro wohejuru wo mu kirere Umuyoboro wihariye
    • Umuyoboro wo mu rwego rwo hejuru

    Ibisobanuro bigufi:

    Umuyoboro wo mu rwego rwohejuru wo mu kirere urakwiriye gukoreshwa muburyo butandukanye, harimo ubwubatsi, peteroli na gaze, hamwe no gutwara abantu mu nyanja. Nimbaraga zayo zisumba izindi kandi ziramba, yashizweho kugirango ihangane nigitutu no kurwanya ruswa, ikaba igisubizo kirambye kubyo ukeneye imiyoboro.


    Ibicuruzwa birambuye

    Ibicuruzwa

    Kumenyekanisha umuyoboro mwiza wo mu bwoko bwa spiral-seam, ibicuruzwa bikubiyemo imbaraga, kuramba hamwe nubuhanga bwuzuye. Imiyoboro yacu ikoresheje uburyo bwo gusudira buhanitse, imiyoboro yacu ikozwe mumashanyarazi ashyushye azengurutswe neza muburyo bwa silindrike kandi asudira kumurongo. Ubu buhanga bwo gukora udushya ntabwo bwongera gusa uburinganire bwimiterere yimiyoboro, ahubwo inemeza ko bushobora guhangana nibisabwa cyane.

    Muri sosiyete yacu, twishimiye ubwitange bwacu butajegajega bwo guhaza abakiriya. Mu myaka yashize, twiyubashye kuba indashyikirwa dushyira imbere ibyo abakiriya bacu bakeneye kuri buri cyiciro cyo kugura. Kuva mbere yo kugurisha kugeza kugurishwa-kugurisha hamwe na serivisi zuzuye nyuma yo kugurisha, twiyemeje kuzuza ibyo abakiriya bacu bakeneye. Ubu buryo bushingiye kubakiriya bwaduteye ikizere nubudahemuka bwabakiriya bacu, bahora bashima ubwiza bwibicuruzwa byacu no kwizerwa kwa serivisi zacu.

    Ubwiza bwacu bwo hejuruumuyoboro wizubaikwiranye nuburyo butandukanye busaba, harimo ubwubatsi, peteroli na gaze, hamwe nubwikorezi bwo mu nyanja. Nimbaraga zayo zisumba izindi kandi ziramba, yashizweho kugirango ihangane nigitutu no kurwanya ruswa, ikaba igisubizo kirambye kubyo ukeneye imiyoboro.

    Ibyiza byibicuruzwa

    1. Kimwe mu byiza byingenzi byumuyoboro wimbaraga nimbaraga zacyo nziza. Inzira yo gusudira izenguruka ituma gusudira guhoraho, bityo bikazamura uburinganire bwimiterere yumuyoboro. Ibi bituma biba byiza gutwara transport na gaze munsi yumuvuduko mwinshi.

    2. Inzira yo gukora irakora neza, ituma imiyoboro miremire ikorwa bidakenewe ingingo, zishobora kuba ingingo zintege nke.

    3. Iyindi nyungu ikomeye yaumuyoboro udasanzweni byinshi. Birashobora kubyazwa umusaruro wa diametre zitandukanye hamwe nubunini bwurukuta kugirango ibintu byinshi bishoboke kuva gutwara peteroli na gaze kugeza sisitemu y'amazi.

    4. Isosiyete ikora iyi miyoboro ishyira imbere kunyurwa kwabakiriya no gutanga ibicuruzwa byuzuye mbere yo kugurisha, mugihe cyo kugurisha, na serivisi nyuma yo kugurisha. Iyi mihigo ituma abakiriya bakira ibicuruzwa bijyanye nibyo bakeneye, bikazamura uburambe muri rusange.

    Ibura ry'ibicuruzwa

    1. Igikorwa cyo gusudira kizunguruka kirashobora kuba ingorabahizi kuruta uburyo bwo gusudira gakondo, ibyo bikaba byavamo umusaruro mwinshi.

    2. Mugihe imiyoboro yikizunguruka ikomeye, irashobora kutarwanya ubwoko bumwe na bumwe bwo kwangirika kuruta ibindi bikoresho byumuyoboro kandi bisaba gutwikira cyangwa kuvura.

    Ibibazo

    Ikibazo1: Umuyoboro wikizunguruka ni iki?

    Umuyoboro wa spiral wubatswe ukoresheje uburyo bwihariye bwitwa spiral welding process. Ubu buhanga bugezweho burimo ibyuma bishyushye bishyushye bikozwe muburyo bwa silindrike kandi bigasudira hamwe. Umuyoboro wavuyemo ntabwo ufite imbaraga nyinshi gusa ahubwo unaramba cyane, bigatuma biba byiza mubikorwa bitandukanye, harimo gutwara peteroli na gaze, gutanga amazi no gutera inkunga imiterere.

    Ikibazo cya 2: Kuki uhitamo umuyoboro mwiza wo hejuru?

    Inyungu nyamukuru yimiyoboro yo mu rwego rwohejuru ni imyubakire yabo ikomeye. Inzira yo gusudira izenguruka ituma gusudira guhoraho, byongera ubunyangamugayo n’umuvuduko ukabije wumuyoboro. Mubyongeyeho, iyi miyoboro irashobora gukorwa mubunini butandukanye nubunini kugirango ihuze ibyifuzo byimishinga itandukanye.

    Q3: Niki nakagombye gushakisha mubitanga?

    Mugihe uhisemo kuzenguruka utanga isoko, nibyingenzi guhitamo isosiyete ishyira imbere kunyurwa kwabakiriya. Shakisha utanga isoko mbere yo kugurisha, kugurisha, na serivisi nyuma yo kugurisha. Isosiyete izwi izemeza ko ibicuruzwa byayo byujuje ibyashizweho kandi bishobora guhuza ibyifuzo byawe byihariye, byemeza ko wakiriye ibicuruzwa na serivisi byujuje ubuziranenge abakiriya bawe bazishimira.
