    Izinzuzo zepayipi likagesi elihlanganisiwe eliphindwe kabili

    Izinzuzo Zepayipi Legesi Elihlanganisiwe Elihlanganisiwe Eliphindwe Kabili Isithombe Esivelele
    • Izinzuzo zepayipi likagesi elihlanganisiwe eliphindwe kabili

    Incazelo emfushane:

    Siyakwamukela eCangzhou Spiral Steel Pipe Group Co., Ltd., umkhiqizi nomhlinzeki odumile wamapayipi ensimbi yekhabhoni ahlanganiswe nge-spiral asezingeni eliphezulu. Inkampani yethu iyaziqhenya ngokusebenzisa ubuchwepheshe obusha bokushisela i-spiral submited arc obuqinisekisa ukukhiqizwa kwamapayipi okuthunga ahlanganisiwe e-spiral asezingeni eliphezulu ezinhlobonhlobo zezicelo.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

    Ezweni lamapayipi, kunezindlela ezahlukahlukene zokwakha nezinto zokwakha. Indlela ethandwayo yokuhlanganisa amapayipi ukushisela i-arc engaphansi kwamanzi okunezinhlangothi ezimbili (i-DSAW). Le ndlela ivame ukusetshenziswa emigqeni yegesi namanzi, futhi ngesizathu esihle. Kule bhulogi sizohlola izinzuzo zokusebenzisai-arc engaphansi kwamanzi ehlanganisiwe kabiliipayipi kulezi zicelo.

    Ukuhlolwa Kwamanzi

    incazelo yomkhiqizo1

    Ipayipi kufanele imelane nokuhlolwa kwe-hydrostatic ngaphandle kokuvuza ngomthungo wokushisela noma umzimba wepayipi.
    Ama-jointer akudingeki ahlolwe ngamanzi, uma nje izingxenye zamapayipi asetshenziswe ekumaka ama-jointer zihlolwe ngempumelelo ngamanzi ngaphambi kokusebenza kokujoyina.

    Ukushisela i-Arc Ecmerged Helical

    Okokuqala, ukushisela i-arc engaphansi kwamanzi kabili kuyindlela ephumelelayo neyongayo yokuhlanganisa amapayipi. Le nqubo ihilela ukwakha i-weld ngokucwilisa ipayipi ku-granular flux kusetshenziswa ama-arc amabili okushisela. Lokhu kudala i-weld eqinile nehlala isikhathi eside engamelana nokucindezela okuphezulu nokucindezeleka, okwenza kube kuhle kakhulu emigqeni yegesi namanzi.

    Enye yezinzuzo eziyinhloko zepayipi elihlanganisiwe elifakwe i-arc elifakwe kabili ngaphansi kwamanzi ukumelana nokugqwala kwalo. I-granular flux esetshenziswa kule nqubo yokushisela idala ungqimba oluvikelayo phezu kwe-weld, okusiza ukuvimbela ukugqwala nokwandisa isikhathi sokuphila kwepayipi. Lokhu kubaluleke kakhuluipayipi lamanzi, njengoba kuqinisekisa ukuthi amanzi alethwayo ahlala ehlanzekile futhi engenakho ukungcola.

    Ngaphezu kokumelana nokugqwala, amapayipi ahlanganisiwe e-arc acwiliswe kabili anikeza izakhiwo ezinhle kakhulu zemishini. Le ndlela ikhiqiza ama-weld afanayo kanye nepayipi eliqinile nelithembekile. Lokhu kubalulekile kumapayipi egesi yemvelo njengoba kuqinisekisa ukuthuthwa okuphephile nokuphumelelayo kwegesi yemvelo ngaphandle kwengozi yokuvuza noma ukwehluleka.

    Ipayipi le-SSAW

    Ngaphezu kwalokho, amapayipi ahlanganisiwe angaphansi kwamanzi aphindwe kabili ayakwazi ukumelana namazinga okushisa aphezulu kanye nezimo zemvelo. Lokhu kuwenza afaneleke kakhulu ekusetshenzisweni kwasogwini kanye nasogwini olungase luvezwe esimweni sezulu esibi kanye nezimo zokusebenza. Ngokuphathelene namapayipi amanzi, lokhu kuqina kuqinisekisa ukuthi amapayipi angahambisa amanzi kahle ngaphandle kokuphazamisa ukusebenza kwawo.

    Enye inzuzo yokusebenzisa ipayipi elihlanganisiwe elifakwe i-arc elifakwe kabili ukuthi ubuso balo bubushelelezi futhi buhle. Lokhu kubenza babe inketho ekhangayo yokufaka ngaphezulu nangaphansi komhlaba, njengoba kulula ukuyihlola nokuyinakekela. Ngaphezu kwalokho, ubuso obubushelelezi bepayipi bunciphisa ukungqubuzana kanye nokwehla kwengcindezi ngaphakathi kwepayipi, okusiza ekuthuthukiseni ukusebenza kahle kwezinhlelo zokulethwa kwegesi namanzi.

    Ekuphetheni, ipayipi elihlanganisiwe le-arc elicwiliswe kabili liyisinqumo esihle kakhuluipayipi lomugqa wegesikanye namapayipi amanzi. Inqubo yayo yokushisela esebenza kahle futhi engabizi kakhulu, kanye nokumelana nokugqwala, izakhiwo ezinhle kakhulu zemishini, ukuqina kanye nobuhle, kwenza kube ukukhetha kokuqala kokwakhiwa kwamapayipi. Kungakhathaliseki ukuthi kuthuthwa igesi yemvelo noma amanzi, la mapayipi anikeza amandla nokuthembeka okudingekayo ukuze asebenze ngokuphepha nangokusebenza kahle. Ngokusobala, ipayipi elihlanganisiwe le-arc elingaphansi kwezingqimba ezimbili liyimpahla ebalulekile emhlabeni wokwakhiwa kwamapayipi.
