Imiyoboro yo gusudira
Ibicuruzwa bisobanura
Imiyoboro yo gusudira, izwi kandi nk'imiyoboro y'icyuma isudira, ikorwa no kuzunguza ibyuma cyangwa imirongo mu buryo bwa tubular hanyuma igasudira ingingo. Hamwe nimiyoboro idafite icyerekezo, ni kimwe mubyiciro bibiri byingenzi byimiyoboro. Ibyingenzi byingenzi nibikorwa byoroshye, igiciro gito, hamwe nuburyo butandukanye.
I. Ibyiciro Byibanze: Gutondekanya muburyo bwo gusudira
Uburyo butandukanye bwo gusudira bugena imikorere y'imiyoboro isudira. Hariho ubwoko butatu bwingenzi:
• Umuyoboro wa Longitudinal Welded (ERW): Nyuma yo kuzunguza umurongo wibyuma mumuzenguruko cyangwa kwaduka kwambukiranya, ikidodo gisudira mu burebure (mu burebure) ku muyoboro. Ibi bitanga umusaruro mwinshi hamwe nigiciro gito, bigatuma bikwiranye nogutwara amazi yumuvuduko muke (nkamazi na gaze) hamwe nibisabwa byubaka. Ibisobanuro rusange birimo ibipimo bito n'ibiciriritse (mubisanzwe ≤630mm).
• Umuyoboro wo gusudira wa spiral (SSAW): Umurongo wibyuma uzunguruka mucyerekezo cyerekezo kandi ikidodo gisudira icyarimwe, bigakora uruziga ruzunguruka. Ikidodo cyo gusudira kirashimangiwe cyane, gitanga imbaraga zidasanzwe kandi zunamye ugereranije n'umuyoboro usudutse. Ibi bituma habaho gukora imiyoboro minini ya diameter (kugeza kuri 3000mm ya diametre) kandi ikoreshwa cyane cyane mu gutwara amazi y’umuvuduko ukabije (nk'imiyoboro ya peteroli na gaze gasanzwe) hamwe n’imiyoboro y’amazi ya komini.
• Umuyoboro wo gusudira udafite umuyonga: Ikozwe mu rupapuro / ibyuma, idafite ingese, isudira ukoresheje inzira nka TIG (tungsten inert gas arc welding) na MIG (icyuma cya arc welding). Ifite ruswa hamwe nubushyuhe bwo hejuru bwo kurwanya ibyuma bitagira umwanda kandi birakwiriye kubisabwa bisaba ibikoresho byiza cyane, nko gutunganya ibiryo, imiti, nibikoresho byubuvuzi. Bikunze gukoreshwa mumashanyarazi mato mato mato.
II. Ibyiza byingenzi
1. Ibiciro mubisanzwe 20% -50% munsi kubisobanuro bimwe. Byongeye kandi, irashobora gukorerwa mubice kandi bikomeza kugirango ishobore gukenerwa cyane.
2. Ibisobanuro byoroshye: Imiyoboro ifite diameter zitandukanye (kuva kuri milimetero nkeya kugeza kuri metero nyinshi), uburebure bwurukuta, hamwe n’ibice byambukiranya (uruziga, kare, na urukiramende) birashobora gukorwa kubisabwa kugirango bihuze ibyifuzo byihariye bikenerwa, harimo ubwubatsi n'inganda.

III. Ibice byingenzi byo gusaba
• Inganda zubaka: Zikoreshwa mugutanga amazi nu miyoboro itwara amazi, imiyoboro irinda umuriro, ibyuma bifasha ibyuma (nka rukuta rwa rukuta n’umwenda), inzugi n’idirishya (imiyoboro y'urukiramende).
• Urwego rw'inganda: Ikoreshwa nk'imiyoboro itwara umuvuduko ukabije w'amazi (amazi, umwuka uhumanye, umwuka), ibikoresho bifasha imiyoboro, izamu ryamahugurwa, nibindi.; imiyoboro minini ya diameter izunguruka ikoreshwa mu mavuta maremare na gazi karemano.
• Umurenge wa Komini: Ikoreshwa mu miyoboro itwara amazi yo mu mijyi, imiyoboro ya gazi (umuvuduko wo hagati n'umuvuduko muke), inkingi z'umuhanda, izamu, n'ibindi.
• Ubuzima bwa buri munsi: Imiyoboro ntoya yo gusudira (nk'imiyoboro y'ibyuma idafite ingese) ikoreshwa mu bikoresho byo mu nzu no mu miyoboro yo mu gikoni (nk'imiyoboro isohora imiyoboro).
