Akamaro k'umuyoboro wa Sawn na Welded mu bikorwa remezo bigezweho, Hagati mu mujyi wa Cangzhou, Intara ya Hebei, hicaye uruganda rukora ibyuma rwabaye urufatiro rw'inganda zikora ibyuma kuva rwashingwa mu 1993. Isosiyete ifite metero kare 350.000, ifite umutungo wa miliyoni 680 z'amafaranga y'u Rwanda, kandi ikoresha abakozi 680 bitanze. Mubicuruzwa byayo byinshi harimo imiyoboro ikozwe kandi isudira, igice cyingenzi cyibikorwa remezo bigezweho, cyane cyane mu gutwara amazi y’ubutaka.
MunsiYabonye Umuyoboro Weldni ngombwa mu gutwara amazi neza kandi yizewe ahantu hatandukanye. Bagize urufatiro rw'ibikorwa remezo bigezweho, bituma amazi meza agera mu ngo, mu bucuruzi, no mu buhinzi. Guhitamo ibikoresho kuriyi miyoboro ni ngombwa, kuko bigomba kwihanganira imikazo y’ibidukikije mu gihe bikomeza ubusugire bwigihe kirekire. Bumwe mu buryo buzwi cyane kuri izi porogaramu ni umuyoboro uzengurutswe n'umuyoboro wa karubone, uzwi cyane kubera imbaraga no kuramba.
S235 JR umuyoboro wibyuma hamwe na X70 SSAW (Spiral Submerged Arc Welded) umuyoboro wibicuruzwa bibiri bisanzwe bikoreshwa cyane muri sisitemu yo kuvoma amazi yo munsi. Umuyoboro wa S235 JR wubahwa cyane kubera imiterere yubukorikori buhebuje, bigatuma ukoreshwa muburyo butandukanye, harimo no gutwara amazi. Ubushobozi bwayo bwo kurwanya ihindagurika mugihe gihangayikishije byemeza ko byujuje ibyifuzo byubutaka.
Uyu munsi, hamwe n’ibikorwa byihuta by’imijyi, gahunda yizewe yo gukwirakwiza amazi yo mu kuzimu yabaye urufunguzo rwo guharanira imibereho yabaturage. Nkumushinga wambere mubikorwa byinganda zikora ibyuma, uruganda rukora ibyuma mumujyi wa Cangzhou, Intara ya Hebei, rwatanze imiyoboro ikora cyane ya Saw Welded kubikorwa remezo byisi kuva yashingwa mumwaka wa 1993. Imiyoboro ya S235 JR ya spiral spiral hamwe na X70 yacengeye arc yasudira imiyoboro ya spiral, hamwe nibikorwa byingenzi byubukorikori, byahindutse ibikoresho byingenzi mumishinga yo kubungabunga amazi yubutaka.
1. Imbaraga nyinshi no kurwanya ruswa birinda umutekano wogukwirakwiza igihe kirekire. S235 JR umuyoboro uzenguruka: Igaragaza uburyo bwiza bwo kurwanya ihindagurika kandi ikwiranye n’ibidukikije bigoye bya geologiya, bigatuma ibikorwa byigihe kirekire bikora neza. Umuyoboro wa X70 SSAW: Ikozwe mu byuma bikomeye cyane hamwe n’ikoranabuhanga rigezweho ryo gusudira, birwanya umuvuduko kandi birwanya ruswa, bikwiranye no kohereza amazi maremare hamwe n’ibidukikije bikaze.
2.Ikoranabuhanga rigezweho rifatanije no kugenzura ubuziranenge bukomeye bituma habaho imiyoboro irambye. Uru ruganda rukoresha tekinoroji ya arc welding (SAW) kugirango igere ku musaruro mwiza wa diameter nini, uruzitiro ruto, rukoresha neza ibikoresho mu gihe rutanga imbaraga. Ku bufatanye n'itsinda ry'umwuga rigizwe n'abantu 680 n'umurongo ugezweho utanga agaciro ka miliyoni 680 z'amayero, turemeza ko buri muyoboro w'icyuma wujuje ubuziranenge mpuzamahanga, ukagira uruhare mu iterambere ry'ibikorwa remezo bibisi. Hamwe no kuzamura ibyifuzo by’imicungire y’amazi ku isi, imiyoboro isukuye y’uruganda rukora ibyuma bya Cangzhou izakomeza gutanga ibisubizo birambye kandi bihendutse ku gutwara amazi y’amakomine, ubuhinzi n’inganda, biteza imbere iyubakwa ry’ibikorwa remezo byo kubungabunga amazi arambye.
imiyoboro ikarishye-isudira ikorwa na Cangzhou Steel Mills ni ikintu cy'ingenzi muri sisitemu y'amazi yo mu butaka. S235 JR na X70 izengurutswe imiyoboro ya arc yasudutse, hamwe nibikoresho byiza bya tekinike kandi birwanya ibidukikije, nibyingenzi kugirango habeho gutwara neza amazi. Urebye imbere, akamaro k'ibicuruzwa bizakomeza kwiyongera, byerekana inganda zikoresha ibyuma bikenera inganda zinoze kandi zishakirwa ibisubizo bishya.
