    Kufotokozera Kwachidule:

    Chitoliro cholumikizidwa ndi spiral ndi gawo lofunika kwambiri pa ntchito zomanga ndi mafakitale, zomwe zimapereka mphamvu ndi kusinthasintha m'magawo osiyanasiyana. Mapaipi awa amadziwika chifukwa cha kulimba kwawo, kugwiritsa ntchito bwino ndalama komanso kusinthasintha, zomwe zimapangitsa kuti akhale abwino kwambiri pakulumikiza mapaipi okhaokha. Mu blog iyi, tifufuza zabwino zogwiritsa ntchito chitoliro cholumikizidwa ndi spiral mu njira zolumikizira mapaipi zokha, makamaka chitoliro chachitsulo cha S355 JR ndi chitoliro cholumikizidwa ndi spiral cha ASTM A252, komanso kufunika kwa chitoliro cha mzere wa X60 SSAW mu ntchito zamafakitale.

    Njira yopangira imayamba ndi kulumikiza zitsulo kumapeto kwa mzere pogwiritsa ntchito welding ya mono- kapena twin-wire submerged arc. Njirayi imatsimikizira kulumikizana kosasunthika pakati pa mutu ndi mchira, zomwe zimapangitsa kuti chitoliro chikhale cholimba. Pambuyo pake, chingwe chachitsulocho chimakulungidwa kukhala ngati chubu. Pofuna kulimbitsa kwambiri payipi, welding ya automatic submerged arc imagwiritsidwa ntchito pokonza welding. Njirayi yowotcherera imawonjezera kulimba, kulola chitolirocho kupirira zovuta zachilengedwe.

    Kuwotcherera kwa Arc Yokhala ndi Helical Drived

    Mapaipi a SAWH adapangidwa kuti agwirizane ndiEN10219miyezo, kuonetsetsa kuti ikugwirizana ndi ntchito zosiyanasiyana zamafakitale. Mapaipi awa amapezeka m'makoma okhuthala kuyambira 6mm mpaka 25.4mm, ndipo ndi oyenera ntchito zosiyanasiyana. Kaya ndi chitukuko cha zomangamanga, mayendedwe amafuta ndi gasi kapena ntchito zomanga, SAWH Pipes imapereka mayankho odalirika komanso ogwira mtima.

    Cangzhou Spiral Steel Pipes Group Co., Ltd. ndi kampani yotsogola kwambiri yopanga mapaipi achitsulo chozungulira m'nyumba. Kampaniyo ili ndi mizere 13 yapadera yopangira mapaipi achitsulo chozungulira ndi mizere 4 yolimbana ndi dzimbiri komanso yoteteza ku kuzizira, yokhala ndi mphamvu yolimba yopangira. Kampaniyo imadziwika bwino popanga mapaipi achitsulo chozungulira chozungulira okhala ndi mainchesi kuyambira Φ219mm mpaka Φ3500mm. Mapaipi awa amapezeka m'makoma osiyanasiyana, zomwe zimathandiza makasitomala kusankha zomwe zikugwirizana ndi momwe akugwiritsira ntchito.

    Chitoliro cha SSAW

    Kudzipereka kwa kampaniyo pa khalidwe labwino kumaonekera mu njira zowongolera khalidwe nthawi yonse yopanga. Chitoliro chilichonse chimawunikidwa bwino kuti chitsimikizire kuti chikukwaniritsa miyezo ya makampani ndi zofunikira za makasitomala. Kuphatikiza apo, kampaniyo ili ndi gulu lodzipereka la akatswiri omwe nthawi zonse amasintha njira zopangira ndikuyambitsa ukadaulo watsopano kuti akwaniritse zosowa zosintha zamakampani.

    Mwachidule, mapaipi a SAWH opangidwa ndi Cangzhou Spiral Steel Pipes Group Co., Ltd. ndi odalirika, olimba komanso oyenera kugwiritsidwa ntchito m'mafakitale osiyanasiyana. Potsatira njira zowongolera bwino khalidwe komanso kutsatira miyezo yapadziko lonse lapansi, mapaipi awa amapereka magwiridwe antchito apamwamba komanso moyo wautali. Ponena za mapaipi achitsulo, chonde khulupirirani ubwino wabwino kwambiri komanso mtengo wabwino kwambiri wa Cangzhou Spiral Steel Pipes Group Co., Ltd.
