Imiyoboro idasanzwe ya spiral kumiyoboro nyamukuru y'amazi
Mu iyubakwa ry'ibikorwa remezo, ibikoresho byakoreshejwe bigira uruhare runini mu kuramba no gukora k'umushinga.Ikintu kimwe ningirakamaro mubikorwa remezo ni umuyoboro uzunguruka.Iyi miyoboro isanzwe ikoreshwa mubikorwa bitandukanye nk'imiyoboro y'amazi n'imiyoboro ya gaze, kandi ibisobanuro byayo, harimo imiyoboro yo gusudira no kuzunguruka, ni ingenzi cyane kugirango ikore neza.Muri iyi blog, tuzareba byimbitse kurispiral welded pipe ibisobanuron'akamaro kabo mu nganda zubaka.
Sumuyoboro wa piralszubatswe hakoreshejwe uburyo bwitwa spiral welding process.Inzira ikubiyemo gukoresha ibishishwa bishyushye bishyushye kugirango bikorwe muburyo bwa silindrike hanyuma bigasudira kumurongo.Igisubizo ni umuyoboro ufite imbaraga nyinshi kandi ziramba, bigatuma uba muburyo butandukanye bwa porogaramu.Iyi miyoboro ikoreshaumuyoborotekinoloji mugihe cyubwubatsi, kureba neza ko irwanya ibintu bitandukanye bidukikije n’ingutu, bigatuma biba byiza mu kuzimu no mu mazi.

Iyo usuzumye ibisobanuro byerekana imiyoboro ya spiral, ni ngombwa kwibanda ku bintu by'ingenzi nka diameter, uburebure bw'urukuta n'urwego rw'ibikoresho.Diameter yumuyoboro igena ubushobozi bwayo bwo gutwara amazi cyangwa gaze, mugihe uburebure bwurukuta bugira uruhare runini muburinganire bwimiterere no kurwanya umuvuduko.Byongeye kandi, urwego rwibintu rugaragaza ubuziranenge hamwe nibigize ibyuma byakoreshejwe kandi ni ikintu cyingenzi mugutekereza kuramba no gukora umuyoboro mugisabwa runaka.
Mu kubakaimiyoboro y'amazi, imiyoboro ya spiral ifite ibyiza byinshi.Imbaraga zabo zikomeye hamwe no kurwanya ruswa zituma biba byiza mu gutwara amazi kure cyane, mugihe guhinduka kwabo gutuma hashyirwaho byoroshye inzitizi ndetse nubutaka butoroshye.Byongeye kandi, gukoresha imiyoboro ya spiral spiral mu miyoboro ya gaze karemano ituma ubwikorezi bwa gaze neza kandi bunoze, butanga umutungo wingenzi mubikorwa byimiturire, ubucuruzi ninganda.
Kuruhande rwibikorwa remezo, imiyoboro ya spirale spirale igengwa nubuziranenge bwinganda n’amabwiriza kugirango barebe ubuziranenge n’imikorere.Kurugero, Ikigo cy’ibikomoka kuri peteroli muri Amerika (API) cyashyizeho ibipimo ngenderwaho mu gukora no gukoresha umuyoboro wa spiral-seam ugaragaza ibisabwa mu bunini, imbaraga, nuburyo bwo gupima.Byongeye kandi, Sosiyete y'Abanyamerika ishinzwe ibizamini n’ibikoresho (ASTM) itanga ibikoresho hamwe n’ibikoresho byerekana imashini zikoreshwa mu miyoboro izenguruka kugira ngo irusheho kwizerwa no kubahiriza amahame y’inganda.
Muri make, imiyoboro ya spiral yasuditswe ni ingenzi ku ruhare rwabo mu kubaka ibikorwa remezo.Byaba bikoreshwa mumiyoboro y'amazi cyangwaimirongo ya gaze, iyi miyoboro itanga imbaraga ntagereranywa, iramba kandi ihindagurika, bigatuma iba ingenzi kwisi ya none.Mu gukurikiza amahame ngengamikorere y'inganda, ikoreshwa ry'imiyoboro ya spirale irinda umutekano no gukora neza ibikorwa remezo bikomeye, bigatanga inzira y'iterambere rirambye n'iterambere ry'abaturage.
