Kufunika kwa macheka ndi welded chitoliro mu zomangamanga Modern, Mu mtima wa Cangzhou, Hebei Province, akukhala zitsulo mphero kuti wakhala mwala wapangodya makampani zitsulo chitoliro kuyambira kukhazikitsidwa kwake mu 1993. Kampani chimakwirira 350,000 lalikulu mamita, akudzitamandira katundu okwana 680 miliyoni RMB, ndi odzipereka antchito 68. Zina mwa zinthu zake zambiri ndi mapaipi ochekedwa ndi owotcherera, omwe ndi gawo lofunika kwambiri la zomangamanga zamakono, makamaka pamayendedwe apansi panthaka.
MobisaSaw Welded Pipendi zofunika pakunyamula madzi moyenera komanso modalirika m'malo osiyanasiyana. Amapanga msana wa zomangamanga zathu zamakono, kuwonetsetsa kuti madzi aukhondo afika kunyumba, mabizinesi, ndi madera aulimi. Kusankhidwa kwa zinthu za mapaipi amenewa n'kofunika kwambiri, chifukwa ayenera kulimbana ndi zovuta za pansi pa nthaka pamene akusunga umphumphu wawo kwa nthawi yaitali. Chimodzi mwazosankha zodziwika bwino pamapulogalamuwa ndi chitoliro chachitsulo cha spirally welded, chodziwika chifukwa champhamvu komanso kulimba kwake.
Chitoliro chachitsulo cha S235 JR ndi X70 SSAW (Spiral Submerged Arc Welded) ndi zinthu ziwiri zomwe zimagwiritsidwa ntchito kwambiri pamapaipi apansi panthaka. Chitoliro cha S235 JR chimalemekezedwa kwambiri chifukwa cha makina ake abwino kwambiri, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito zosiyanasiyana, kuphatikiza mayendedwe amadzi. Kukhoza kwake kukana ma deformation pansi pa kupsinjika kumatsimikizira kuti ikukwaniritsa zofunikira za malo apansi panthaka.
Masiku ano, chifukwa cha kuwonjezereka kwa mizinda, njira yodalirika yotumizira madzi apansi panthaka yakhala chinsinsi chothandizira kuti anthu azikhala ndi moyo. Monga bizinesi kutsogolera makampani zitsulo Chitoliro kupanga, ena zitsulo zomera Cangzhou City, Hebei Province, wakhala kupereka mkulu-ntchito macheka welded mapaipi kwa zomangamanga padziko lonse kuyambira kukhazikitsidwa kwake mu 1993. S235 JR mipope zitsulo ndi X70 kumizidwa Arc welded mipope ozungulira, ndi ntchito zawo zabwino kwambiri zopangira madzi convant.
1. Mphamvu zazikulu ndi kukana kwa dzimbiri zimatsimikizira chitetezo chotenga madzi kwa nthawi yayitali. Chitoliro chozungulira cha S235 JR: Imakhala ndi kukana kwambiri kupsinjika kwapaipi ndipo ndiyoyenera madera ovuta a geological, kuwonetsetsa kuti payipi ikugwira ntchito kwanthawi yayitali. Chitoliro cha X70 SSAW: Chopangidwa ndi chitsulo champhamvu kwambiri komanso ukadaulo wowotcherera wozungulira wozungulira, ndi wosagwira ntchito komanso wosagwirizana ndi dzimbiri, yoyenera kutumizira madzi mtunda wautali komanso malo ovuta.
2. Ukadaulo wotsogola wophatikizidwa ndi kuwongolera kokhazikika kwabwino kumapanga dongosolo lokhazikika la mapaipi. Fakitale iyi imagwiritsa ntchito ukadaulo wa spiral submerged arc welding (SAW) kuti ikwaniritse bwino kupanga machubu akulu akulu, okhala ndi mipanda yopyapyala, kukhathamiritsa kugwiritsa ntchito zinthu ndikuwonetsetsa mphamvu. Pogwirizana ndi gulu la akatswiri la anthu 680 ndi mzere wamakono wopanga mtengo wa 680 miliyoni wa yuan, timaonetsetsa kuti chitoliro chilichonse chachitsulo chikugwirizana ndi miyezo yapadziko lonse, zomwe zimathandizira pa chitukuko cha zomangamanga zobiriwira. Ndi kukweza kwa zofuna za kasamalidwe ka madzi padziko lonse lapansi, mapaipi opangidwa ndi macheka a Cangzhou Steel Plant apitiliza kupereka mayankho okhalitsa komanso otsika mtengo amayendedwe am'matauni, aulimi ndi mafakitale, kulimbikitsa ntchito yomanga malo osungira madzi okhazikika.
mapaipi ocheka ndi omata opangidwa ndi Cangzhou Steel Mills ndi gawo lofunikira kwambiri pamadzi apansi panthaka. S235 JR ndi X70 spiral submiral welded arc mapaipi, omwe ali ndi mawonekedwe abwino amakina komanso kukana zinthu zachilengedwe, ndizofunikira pakuwonetsetsa kuyenda bwino kwamadzi. Kuyang'ana m'tsogolo, kufunikira kwa zinthuzi kudzapitiriza kukula, ndikuwunikira kufunika kwa makampani azitsulo zazitsulo zopangira zinthu zapamwamba komanso zothetsera nzeru.
