    Ubuyobozi bwuzuye bwa SAWH kuri Tube: Umuyoboro w'icyuma wa A252 Grade 1 wo gukoresha peteroli na gaze Ishusho yagaragaye
    • Ubuyobozi bwuzuye bwa SAWH kuri Tube: Umuyoboro w'icyuma wa A252 Grade 1 wo gukoresha peteroli na gaze

    Ibisobanuro bigufi:

    Umuyoboro wa SAWH (Sumerged Arc Welded Spiral) ukoreshwa cyane mu nganda za peteroli na gaze bitewe n'imbaraga zawo zidasanzwe no kuramba kwawo. Muri iyi blog, tuzasuzuma ibintu by'ingenzi n'ibyiza byaUmuyoboro w'icyuma wa A252 Grade 1 ikoreshwa cyane mu bijyanye na peteroli na gaze. Amaherezo, uzasobanukirwa neza imiyoboro ya SAWH n'akamaro kayo mu nganda.


    Ibisobanuro birambuye ku gicuruzwa

    Ibirango by'ibicuruzwa

    1. Sobanukirwa n'umuyoboro wa SAWH:

    imiyoboro ya SAWHzikorwa mu byuma bikozwe mu buryo bwo kuzunguruka. Amabati akorwamo imiyoboro hanyuma agasukwa hakoreshejwe uburyo bwo gusudira mu mazi. Ubu buryo bwo gusudira butuma umuyoboro ukomeza gusukwa neza kandi uhoraho, bigatuma urwanya cyane ibintu biturutse hanze nko guhungabana no gushyuha. Iyi miyoboro izwiho ubushobozi bwayo bwo gutwara imizigo n'imiterere yayo, bigatuma iba nziza cyane mu gutwara peteroli na gaze.

    2. Umuyoboro w'icyuma wa A252 wo mu rwego rwa 1:

    A252 GRADE 1 ni uburyo bwihariye bwo gukoresha imiyoboro y'icyuma mu buryo bwihariye kugira ngo ikoreshwe mu buryo bw'umuvuduko. Iyi miyoboro ikozwe mu cyuma cya A252, gifite imiterere myiza ya mekanike n'imbaraga nyinshi zo gukurura. Umuyoboro w'icyuma wa A252 GRADE 1 ukoreshwa cyane kubera ubushobozi bwawo bwo kwihanganira umuvuduko mwinshi no kurwanya ingese no kwangirika mu bidukikije bikomeye bya peteroli na gaze.

    3. Ibyiza by'umuyoboro w'icyuma wa A252 grade 1:

    a) Ingufu no Kuramba:Umuyoboro w'icyuma wa A252 GRADE 1Irakomeye kandi irakomeye, ishobora kwihanganira imitwaro iremereye kandi ikwiriye uburyo bwo kohereza peteroli na gaze. Ingufu zayo zo gukurura cyane zituma iramba igihe kirekire kandi zigagabanya ibisabwa mu kubungabunga.

    b) Ubudahangarwa ku ngaruka: Imiyoboro ya peteroli na gaze ikunze kwangirika bitewe n’ibintu bikomeye bidukikije. Umuyoboro w’icyuma wa A252 GRADE 1 ufite ikindi gikoresho kidahangarwa n’ingaruka, nka epoxy ifatanye na fuse (FBE), kugira ngo wongere igihe cyayo cyo kuramba no kongera igihe cyo kuyikoresha.

    c) Koroshya: Imiyoboro ya SAWH ishobora gukorwa mu burebure n'uburebure butandukanye kugira ngo ihuze n'ibisabwa by'umushinga. Ubu buryo bworoshye bwo kuyishyiraho hatabayeho gukenera imiyoboro myinshi, bigabanya ibyago byo kuva amazi.

    d) Ihendutse: Umuyoboro w'icyuma wa A252 Grade 1 utanga igisubizo gihendutse ku miyoboro ya peteroli na gazi. Igihe kirekire ikora kandi isaba kuyitaho bike bigabanya ikiguzi cyo kuyikoresha uko igihe kigenda gihita.

    a. Uburyo bwo gukuraho ogisijeni mu mubiri bugenwa ku buryo bukurikira:

    FF: Icyuma cyapfuye cyose kirimo ibintu bihuza azote mu rugero ruhagije kugira ngo gifatanye azote ihari (urugero: 0.020% by'Al yose cyangwa 0.015% by'Al ishongesha).

    b. Agaciro ntarengwa ka azote ntigakurikizwa iyo imiterere y’imiti igaragaza ko Al yose hamwe na 0.020% hamwe na Al/N ya 2:1, cyangwa niba hari ibindi bintu bihagije bihambira kuri N. Ibintu bihambira kuri N bigomba kwandikwa mu nyandiko y’igenzura.

    4. Gukoresha umuyoboro w'icyuma wa A252 grade 1:

    Umuyoboro w'icyuma wa A252 Grade 1 ufite uburyo bwinshi bwo gukoreshwa mu nganda za peteroli na gaze, harimo:

    a) Imiyoboro y'amashanyarazi: ikoreshwa mu gutwara peteroli, gaze karemano n'ibindi bikomoka kuri peteroli biva mu nganda zitunganya peteroli bikajya mu nganda zitunganya peteroli n'ibigo biyikwirakwiza.

    b) Gucukura mu mazi: Imiyoboro ya SAWH ikoreshwa mu bikorwa byo gucukura peteroli na gaze mu mazi. Ubushobozi bwayo bwo kurwanya ingese n'umuvuduko mwinshi bituma ikoreshwa mu gucukura mu nyanja nini.

    c) Uruganda rutunganya peteroli: Imiyoboro y'icyuma ya A252 GRADE 1 ikoreshwa cyane mu nganda zitunganya peteroli mu gutwara peteroli n'ibikomoka kuri peteroli.

    Umuyoboro wa SSAW

    Mu gusoza:

    Imiyoboro ya SAWH, cyane cyane imiyoboro y'icyuma ya A252 GRADE 1, igira uruhare runini muriumuyoboro wa peteroli na gazeInganda. Ingufu zazo, kuramba kwazo, no kudatwarwa n’ingufu bituma ziba amahitamo yizewe ku bikorwa bitandukanye. Gusobanukirwa ibyiza by’imiyoboro ya SAWH n’imiterere yayo byihariye bishobora gufasha mu gutwara peteroli na gaze neza, ndetse no kugabanya ikiguzi cyo kubungabunga no kongera imikorere myiza y’umushinga.
