Mu rwego rwo kohereza ingufu ku isi, imishinga y’ibikorwa remezo, n’ubwubatsi bwo kubungabunga amazi, icyifuzo cy’ibikoresho by’imiyoboro bikora neza kandi byizewe cyane gikomeje kwiyongera. Umuyoboro ukozwe mu cyuma gishyushya amazi (spiral submerged arc welded)Umuyoboro wometseho amazi winjira mu mazi) yabaye ubwoko bw'imiyoboro ikunzwe cyane mu mishinga myinshi y'ingenzi bitewe n'ubushobozi bwayo bwiza bwo gutwara umuvuduko, ubushobozi bwo guhindura uburebure bw'umurambararo, n'uburyo bwo kuyikora buhendutse. Mu guhitamo ibikoresho by'imiyoboro, gusobanukirwa neza imiterere y'imiyoboro ikoze mu buryo bwa spiral welded (Ibisobanuro by'umuyoboro wa spiral welded) ni ryo shingiro ryo kwemeza umutekano n'iterambere ry'umushinga. Iyi nkuru igamije gutanga ubuyobozi bwuzuye bw'ibipimo no kwerekana uburyo Cangzhou Spiral Steel Pipe Group yujuje ibisabwa mu nganda hamwe n'ibicuruzwa byayo by'indashyikirwa.
Igicuruzwa cyiza cyane: Umuyoboro wa Gazi wo Gusudira wa ASTM A252 ufite impande ebyiri
Turasaba cyane umuyoboro wa gazi wo mu bwoko bwa ASTM A252 ufite impande ebyiri ukoreshwa mu gusudira ku isoko. Iki gicuruzwa cyakozwe hakurikijwe ibipimo ngenderwaho bya ASTM A252 byemewe ku rwego mpuzamahanga kandi gikoresha uburyo bwa SSAW bwo gusudira bugezweho. Ubu buryo, binyuze mu gushushanya no gusudira imiyoboro yo mu bwoko bwa spiral, butuma imiyoboro y'icyuma ikoreshwa mu gusudira ingana kandi ikagira imbaraga zihagije, bityo bigatuma umuyoboro w'icyuma ugira imbaraga n'ubukomere buhagije, cyane cyane bukoreshwa mu gukwirakwiza gazi munsi y'ubutaka mu gihe cy'umuvuduko mwinshi. Ibicuruzwa byacu bikubiyemo uburebure butandukanye bw'umurambararo n'ubugari bw'inkuta, kandi bishobora kuzuza ibisabwa byihariye by'imiterere itandukanye y'ubuhanga ku bipimo by'imiyoboro yo mu bwoko bwa spiral, bigatanga ibisubizo byihariye ku mishinga.
Ubwitange bukomeye bw'inganda zikomeye mu Bushinwa
Nk'ikigo gikomeye mu miyoboro y'ibyuma bizunguruka n'ibicuruzwa bitwikiriye imiyoboro y'amazi mu Bushinwa, Cangzhou Spiral Steel Pipe Group Co., Ltd. yiyemeje guhanga udushya mu ikoranabuhanga no kunoza ubuziranenge kuva yashingwa mu 1993. Iherereye mu Mujyi wa Cangzhou, mu Ntara ya Hebei, iyi sosiyete ifite ubuso bwa metero kare 350.000 kandi ifite umutungo wa miliyoni 680 z'amayuan. Ifite abakozi b'inzobere 680. Dufite ubushobozi bwo gukora toni 400.000 z'imiyoboro y'ibyuma bizunguruka buri mwaka n'agaciro k'umusaruro ka miliyari 1.8 z'amayuan buri mwaka, ntabwo dufite gusa ubushobozi bwo kwemeza ko ibicuruzwa binini, bihamye kandi ku gihe, ahubwo dushobora no guhuza sisitemu ikomeye yo kugenzura ubuziranenge muri buri sano kuva ku bikoresho fatizo kugera ku gicuruzwa cya nyuma, tukareba ko buri muyoboro wa ASTM A252 uva mu ruganda wujuje cyangwa urenze imikorere n'ibipimo by'imiyoboro izunguruka abakiriya biteze.
Guhitamo Cangzhou Spiral Steel Pipe Group bivuze ko utahisemo gusa ubuyobozi bwuzuye ku bipimo by’imiyoboro ikoze mu buryo bwa spiral welded n’ibicuruzwa byujuje ibisabwa, ahubwo unahitamo n’umufatanyabikorwa w’ingamba ufite uburambe bw’imyaka hafi 30 mu mwuga, ubushobozi bukomeye n’ubushobozi bwo kuyitanga bwizewe. Twiyemeje gukorana n’abakiriya bo ku isi yose kugira ngo dukemure ibibazo by’ubuhanga no kubaka ahazaza hatekanye kandi hanoze dukoresheje ubuhanga bwacu n’ubushobozi bwacu bwo gukora.
