M'dziko lalikulu la uinjiniya wamafakitale, gawo limodzi lofunikira lomwe limatsimikizira mphamvu ndi kudalirika nthawi zambiri limamanyalanyazidwa - chitoliro chozungulira chozungulira. Ngakhale kuti ndi yotsika, chodabwitsa cha uinjiniyachi chimakhala ndi kusinthasintha kodabwitsa ndipo ndichoyenera kugwiritsa ntchito zambiri m'mafakitale osiyanasiyana. Pamene tikufufuza mozama za zovuta za spiral welding, tiwona momwe tingaphatikizire mphamvu ndi mphamvu zaukadaulo wamakonowu kuti uwonjeze kuthekera kwake pamapulojekiti anu.
Spiral welded chitoliroamapangidwa ndi spiral kukulunga chingwe chachitsulo chathyathyathya kuzungulira mandrel ndiyeno kuwotcherera motsatira msoko. Njira imeneyi sikuti kumangowonjezera structural kukhulupirika kwa chitoliro, komanso amalola kupanga diameters zikuluzikulu ndi utali wautali kuposa njira kuwotcherera ochiritsira. Chogulitsa chomaliza sichiri cholimba komanso chokhazikika, komanso chogwira ntchito kwambiri pogwiritsira ntchito zinthu komanso nthawi yopanga zinthu.
Ubwino umodzi waukulu wa mipope yowotcherera yozungulira ndikutha kupirira kupsinjika kwakukulu komanso mikhalidwe yoyipa ya chilengedwe. Izi zimawapangitsa kukhala abwino kwa mafakitale monga mafuta ndi gasi, madzi, ndi zomangamanga. Pogwiritsa ntchito mapaipi opangidwa ndi spiral welded, mainjiniya amatha kuonetsetsa kuti ntchito yawo ipitilira, kuchepetsa kufunika kokonzanso pafupipafupi ndikusintha zina.
Kuti tikwaniritse bwino komanso kulimba kwa ma welds ozungulira, zinthu zingapo zofunika ziyenera kuyang'ana panthawi yopanga. Choyamba, kusankha zipangizo zapamwamba ndizofunikira. Chitsulo chomwe chimagwiritsidwa ntchito popanga mipope yowotcherera yozungulira chiyenera kukwaniritsa miyezo yamakampani kuti zitsimikizire kuti zikuyenda bwino. Komanso, ntchito luso kuwotcherera patsogolo ndi njira akhoza kwambiri kusintha khalidwe kuwotcherera, chifukwa champhamvu ndi odalirika mankhwala.
Chinthu china chofunika kuganizira ndi mapangidwe a chitoliro chokha. Mwa kukhathamiritsa ma geometry ndi makulidwe a chitoliro chowotcherera chozungulira, mainjiniya amatha kukwaniritsa mphamvu ndi kulemera, zomwe zimapangitsa kuti zikhale zosavuta kuzigwira ndikuyika. Izi ndizopindulitsa makamaka m'mapulojekiti akuluakulu momwe kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake kangayambitse mavuto aakulu.
Fakitale yathu ili ku Cangzhou, Hebei Province, ndipo yakhala ikupanga apamwambaspiral weldmapaipi kuyambira kukhazikitsidwa kwake mu 1993. Fakitaleyi ili ndi malo okwana 350,000 square metres, ili ndi chuma chonse cha RMB 680 miliyoni, ndipo ili ndi luso lamakono komanso ogwira ntchito aluso a 680. Izi zimatithandiza kukhala ndi ulamuliro wokhwima pa nthawi yonse yopangira zinthu, kuonetsetsa kuti katundu wathu akugwirizana ndi miyezo yapamwamba yamakampani.
Kuwonjezera pa kudzipereka kwathu ku khalidwe labwino, timayikanso kukhutira kwamakasitomala patsogolo. Gulu lathu la akatswiri limapezeka nthawi zonse kuti lipereke chitsogozo ndi chithandizo chothandizira makasitomala kusankha chitoliro choyenera cha spiral welded pazosowa zawo zenizeni. Kaya mukugwira ntchito yomanga nyumba yayikulu kapena pulogalamu yaying'ono, tidzakuthandizani kugwiritsa ntchito chitoliro cha spiral welded.
Mwachidule, kuphatikiza mphamvu ndi mphamvu ya spiral welded chitoliro ndikofunikira kuti apambane pamafakitale osiyanasiyana. Poyang'ana kwambiri zida zapamwamba, njira zapamwamba zowotcherera, ndi mapangidwe okhathamiritsa, mainjiniya amatha kupanga mayankho amphamvu omwe amapirira nthawi yayitali. Pamalo athu a Cangzhou, timanyadira kuthandizira pazatsopanozi, kupereka zinthu zodalirika zomwe zimakwaniritsa zofuna zaukadaulo wamakono. Landirani kusinthasintha kwa spiral welded pipe ndikutenga mapulojekiti anu kukhala okwera kwambiri komanso mwamphamvu.
