    SAWH Igitabo Cyuzuye Kuri Tube: A252 Icyiciro cya 1 Umuyoboro wibyuma Kubikoresha Amavuta na Gazi Byerekanwe Ishusho
    • SAWH Igitabo Cyuzuye Kuri Tube: A252 Icyiciro cya 1 Umuyoboro wibyuma Kubikoresha Amavuta na Gazi

    Ibisobanuro bigufi:

    SAWH (Submerged Arc Welded Spiral) umuyoboro ukoreshwa cyane munganda za peteroli na gaze kubera imbaraga zisumba izindi kandi ziramba.Muri iyi blog, tuzasesengura ibintu byingenzi nibyiza byaA252 Icyiciro cya 1 cyicyuma bisanzwe bikoreshwa mumavuta na gaze.Hanyuma, uzasobanukirwa byimazeyo imiyoboro ya SAWH n'akamaro kayo mu nganda.

    1. Sobanukirwa n'umuyoboro wa SAWH:

    Imiyoboro ya SAWHbikozwe mubyuma bitunganijwe neza.Amabati akozwe mubituba no gusudira hifashishijwe uburyo bwo gusudira arc bwarohamye.Ubu buryo bwo gusudira butuma gusudira gukomeye, guhoraho mu burebure bwose bw'umuyoboro, bigatuma irwanya cyane ibintu bitera impungenge nk'ingaruka n'umuvuduko.Iyi miyoboro izwiho ubushobozi budasanzwe bwo gutwara imizigo hamwe nuburinganire bwimiterere, bigatuma biba byiza gutwara peteroli na gaze.

    2. A252 icyiciro cya 1 umuyoboro wibyuma:

    A252 GRADE 1 nigisobanuro cyumuyoboro wibyuma byubatswe byabugenewe.Iyi miyoboro ikozwe mu byuma bya A252, ifite imiterere yubukanishi nimbaraga zikomeye.A252 GRADE 1 umuyoboro wicyuma ukoreshwa cyane mubushobozi bwawo bwo guhangana n’umuvuduko mwinshi no kurwanya ruswa no guhindagurika mu mavuta akaze na gaze.

    3. Ibyiza bya A252 icyiciro cya 1 umuyoboro wibyuma:

    a) Imbaraga no Kuramba:A252 GRADE 1 umuyoboro wibyumairakomeye kandi iramba, irashobora kwihanganira imitwaro iremereye kandi ikwiranye na sisitemu yohereza peteroli na gaze.Imbaraga zabo zingana cyane zituma igihe kirekire kandi kigabanya ibisabwa byo kubungabunga.

    b) Kurwanya ruswa: Imiyoboro ya peteroli na gaze ikunda kwangirika bitewe n’ibidukikije bikabije.A252 GRADE 1 umuyoboro wibyuma urimo iyindi myenda irwanya ruswa, nka epoxy yahujwe na epoxy (FBE), kugirango irusheho kuramba no kongera ubuzima bwa serivisi.

    c) Guhinduka: imiyoboro ya SAWH irashobora gukorwa mubipimo bitandukanye bya diametre n'uburebure kugirango byuzuze ibisabwa byumushinga.Ihinduka ryorohereza kwishyiriraho bidakenewe ingingo nyinshi, bigabanya ibyago byo kumeneka.

    d) Igiciro-cyiza: A252 Icyiciro cya 1 cyicyuma gitanga igisubizo cyigiciro cyumuyoboro wa peteroli na gaze.Ubuzima bwabo burebure hamwe nibisabwa byo kubungabunga bigabanya amafaranga yo gukora mugihe runaka.

    A252 Icyiciro cya 1 cyicyuma gifite ibyiciro byinshi mubikorwa bya peteroli na gaze, harimo:

    a) Imiyoboro yohereza: ikoreshwa mu gutwara peteroli, gaze gasanzwe n’ibindi bicuruzwa bikomoka kuri peteroli biva mu bicuruzwa biva mu nganda no mu bigo bikwirakwiza.

    b) Gucukura hanze: Imiyoboro ya SAWH ikoreshwa mubikorwa byo gucukura peteroli na gazi yo hanze.Kurwanya ruswa hamwe nubushobozi bwumuvuduko mwinshi bituma bakora ubushakashatsi bwimbitse bwinyanja.

    c) Uruganda rutunganya: A252 GRADE 1 imiyoboro yicyuma ikoreshwa cyane munganda zitwara amavuta ya peteroli yatunganijwe nibikomoka kuri peteroli.
