Mwisi yisi igenda itera imbere yubwubatsi nibikorwa byinganda, gukenera ibikoresho bikomeye kandi byizewe nibyingenzi. Muri ibyo bikoresho, imiyoboro ibiri yo gusudira, cyane cyane yujuje ubuziranenge bwa ASTM A252, yabaye ibuye rikomeza imfuruka mu bice bitandukanye. Iyi blog irasesengura ibyakoreshejwe imiyoboro ibiri yo gusudira mubwubatsi bugezweho ninganda, byerekana akamaro kayo nibyiza byabo.
Umuyoboro wikubye kabiri, bizwi kandi nka DSAW (double submerged arc welded) umuyoboro, irashobora kwihanganira umuvuduko mwinshi kandi ikwiranye nibidukikije bitandukanye bisaba. Igipimo cya ASTM A252 kigenga gukora iyi miyoboro yizewe naba injeniyeri ninzobere mu bwubatsi imyaka myinshi. Igipimo cyemeza ko imiyoboro yujuje ubuziranenge n’imikorere, bigatuma iba nziza mu bwubatsi, peteroli na gaze, n’ibindi bikorwa biremereye by’inganda.
Imwe mumikorere nyamukuru yimiyoboro ibiri yasudutse ni mukubaka amakadiri yubatswe. Hamwe nimbaraga nigihe kirekire bisabwa kugirango dushyigikire imitwaro iremereye, iyi miyoboro nikintu cyingenzi mukubaka ibiraro, inyubako, nindi mishinga remezo. Ubushobozi bwabo bwo guhangana ningutu nyinshi nabwo butuma bikoreshwa mugukoresha piling, aho bajugunywe mubutaka kugirango batange inkunga yifatizo.
Mu nganda za peteroli na gaze,Imiyoboro ya DSAWigira uruhare runini mu gutwara amazi na gaze. Ubwubatsi bwayo bukomeye butuma ishobora guhangana n’umuvuduko mwinshi ujyanye nibi bikoresho, bigatuma ubwikorezi butekanye kandi bunoze. Byongeye kandi, kurwanya ruswa ya DSAW ituma ihitamo neza kubidukikije bikaze, nkibibuga byo gucukura byo hanze no gutunganya inganda, aho guhangayikishwa nibintu byangirika.
Gukora imiyoboro ibiri yo gusudira ninzira yoroshye isaba ubuhanga nubuhanga. Uruganda rwacu ruherereye mu mujyi wa Cangzhou, mu Ntara ya Hebei, kandi rukaba ku isonga mu nganda kuva rwashingwa mu 1993. Uru ruganda rufite ubuso bwa metero kare 350.000, rufite umutungo wa miliyoni 680 z'amafaranga y'u Rwanda, kandi rufite ibikoresho bigezweho ndetse n'abakozi 680 bafite ubumenyi. Ibi bidushoboza gukora imiyoboro ya gazi ya DSAW yujuje ubuziranenge yujuje ibyangombwa bisabwa byubwubatsi bugezweho nibikorwa byinganda.
Byongeye kandi, impinduramatwara yimiyoboro ibiri yasudutse irenze ibyo basanzwe bakoresha. Zikoreshwa cyane mumishinga yingufu zishobora kuvugururwa, nkumuyaga nizuba, aho zikora nkibikoresho byubaka ndetse numuyoboro wohereza ingufu. Mugihe isi igenda igana ibisubizo birambye byingufu, uruhare rwimiyoboro ibiri isudira mukorohereza iyi nzibacyuho ntishobora kuvugwa.
Mugusoza, gusaba kwa KabiriUmuyoboromubwubatsi bugezweho ninganda ni nini kandi ziratandukanye. Zujuje ubuziranenge bwa ASTM A252, zemeza ko ubuziranenge n’ibikorwa byujuje ubuziranenge byujujwe, bigatuma bahitamo kwizerwa ku ba injeniyeri n’inzobere mu bwubatsi. Mu gihe inganda zikomeje gutera imbere no guhangana n’ibibazo bishya, akamaro k’ibikoresho byizewe nka Double Welded Pipe biziyongera gusa. Twiyemeje gukora imiyoboro ya gazi ya DSAW yo mu rwego rwo hejuru yatugize umuyobozi mu rwego, twiteguye kuzuza ibisabwa ejo hazaza. Haba mu bwubatsi, peteroli na gaze cyangwa ingufu zishobora kongera ingufu, Umuyoboro wa Welded Double uzagira uruhare runini mu gushiraho ibikorwa remezo by'ejo hazaza.
