Ibyiza bya Double Submerged Arc Welded Gas Line Umuyoboro
Mw'isi y'amazi, hariho uburyo butandukanye bwo kubaka nibikoresho.Uburyo buzwi bwo guhuza imiyoboro nuburyo bubiri-bwarangije kurengerwa arc gusudira (DSAW).Ubu buhanga bukunze gukoreshwa kumurongo wa gazi namazi, kandi kubwimpamvu.Muri iyi blog tuzasesengura ibyiza byo gukoreshakabiri yarengewe arc gusudiraUmuyoboro muri iyi porogaramu.

Ikizamini cya Hydrostatike
Umuyoboro ugomba kwihanganira ibizamini bya hydrostatike bitanyuze mu kashe cyangwa umubiri
Ihuriro ntirigomba gupimwa hydrostatike, mugihe ibice byumuyoboro wakoreshejwe mugushira ahabona byageragejwe neza hydrostatike mbere yo guhuza ibikorwa.
Ubwa mbere, gusudira kabiri arc gusudira nuburyo bwiza kandi bwubukungu bwo guhuza imiyoboro.Inzira ikubiyemo gukora gusudira wibiza umuyoboro mumazi ya granular ukoresheje arc ebyiri zo gusudira.Ibi birema gusudira gukomeye kandi kuramba gushobora kwihanganira umuvuduko mwinshi hamwe nimpagarara, bigatuma biba byiza kumirongo ya gazi namazi.
Kimwe mu byiza byingenzi byamazi abiri arengerwa arc gusudira umuyoboro ni ukurwanya ruswa.Amazi ya granular akoreshwa muriki gikorwa cyo gusudira akora urwego rwo gukingira hejuru ya weld, bifasha mukurinda kwangirika no kongera ubuzima bwumuyoboro.Ibi ni ngombwa cyane cyane kuriumuyoboro w'amazi, nkuko byemeza ko amazi yatanzwe akomeza kuba meza kandi nta kwanduza.
Usibye kwangirika kwangirika, imiyoboro ibiri arc yarengewe imiyoboro itanga ibikoresho byiza byubukanishi.Ubu buryo butanga imashini imwe hamwe numuyoboro ukomeye kandi wizewe.Ibi ni ingenzi ku miyoboro ya gazi isanzwe kuko itanga ubwikorezi bwiza kandi bunoze bwo gutwara gaze karemano nta ngaruka zo gutemba cyangwa gutsindwa.
Byongeye kandi, imiyoboro ibiri arc yarengerwa imiyoboro irashobora kwihanganira ubushyuhe bukabije nibidukikije.Ibi bituma bakora neza kubutaka no kumurongo ushobora guhura nikirere kibi nikirere gikora.Kumurongo wamazi, uku kuramba kwemeza ko imiyoboro ishobora gutwara amazi neza bitabangamiye imikorere.
Iyindi nyungu yo gukoresha imiyoboro ibiri arc yarengewe ni uko ubuso bwayo bworoshye kandi bwiza.Ibi bituma bahitamo uburyo bwiza bwo gushiraho hejuru no munsi yubutaka, kuko byoroshye kugenzura no kubungabunga.Byongeye kandi, ubuso bworoshye bwa weld bugabanya ubukana nigabanuka ryumuvuduko mumiyoboro, bifasha kuzamura imikorere rusange ya sisitemu yo gutanga amazi namazi.
Mu gusoza, imiyoboro ibiri yuzuye arc welded umuyoboro ni amahitamo meza kuriumuyoboro wa gazin'umuyoboro w'amazi.Uburyo bukora neza kandi buhendutse bwo gusudira, bufatanije no kurwanya ruswa, imiterere yubukanishi buhebuje, kuramba hamwe nuburanga, bituma ihitamo bwa mbere mu kubaka imiyoboro.Haba gutwara gaze gasanzwe cyangwa amazi, iyi miyoboro itanga imbaraga nubwizerwe bukenewe kugirango ikore neza kandi neza.Ikigaragara ni uko ibice bibiri byacengewe arc gusudira umuyoboro ni umutungo w'agaciro mu iyubakwa ry'imiyoboro.
