    Izinzuzo ze-Double Submerged Arc Welded Gas Line Pipe

    Izinzuzo ze-Double Submerged Arc Welded Gas Line Pipe Isithombe Esifakiwe
    • Izinzuzo ze-Double Submerged Arc Welded Gas Line Pipe

    Incazelo emfushane:

    Siyakwamukela ku-Cangzhou Spiral Steel Pipe Group Co., Ltd., umkhiqizi owaziwayo kanye nomphakeli wamapayipi ensimbi ensimbi avunguzayo asontelwe ngensimbi.Inkampani yethu iyaziqhenya ngokusebenzisa ubuchwepheshe bokushisela obuyi-spiral submerged arc obuqinisekisa ukukhiqizwa kwamapayipi omthungo asezingeni eliphezulu ukuze kusetshenziswe izinhlobo ezahlukene.


    Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    Ezweni lamapayipi, kunezinhlobonhlobo zezindlela zokwakha nezinto zokwakha.Indlela edumile yokuhlanganisa amapayipi i-double-ended submerged arc welding (DSAW).Le nqubo ivame ukusetshenziswa emigqeni yegesi namanzi, futhi ngesizathu esihle.Kule bhulogi sizohlola izinzuzo zokusebenzisai-arc ecwiliswe kabili eshiselweipayipi kulezi zicelo.

    Ukuhlolwa kwe-Hydrostatic

    incazelo yomkhiqizo1

    Ipayipi kufanele imelane nokuhlolwa kwe-hydrostatic ngaphandle kokuvuza ngomthungo we-weld noma umzimba wepayipi
    Amajoyinti akudingeki ahlolwe nge-hydrostatically, inqobo nje uma izingxenye zepayipi ezisetshenziswa umaka amajoyinti zihlolwe ngempumelelo nge-hydrostatically ngaphambi kokuhlanganisa.

    I-Helical Submerged Arc Welding

    Okokuqala, ukushisela kwe-arc okungaphansi kwamanzi okuphindwe kabili kuyindlela ephumelelayo neyongayo yokuhlanganisa amapayipi.Inqubo ihilela ukwenza i-weld ngokucwilisa ipayipi ku-flux granular usebenzisa ama-arc amabili wokushisela.Lokhu kudala i-weld eqinile futhi ehlala isikhathi eside ekwazi ukumelana nokucindezela okuphezulu nokushuba, okuyenza ibe ilungele izintambo zegesi nezamanzi.

    Enye yezinzuzo eziyinhloko zamapayipi ashiselwe i-arc acwilisiwe kabili ukumelana nokugqwala.I-granular flux esetshenziswa kule nqubo yokushisela idala isendlalelo esivikelayo phezu kwe-weld, okusiza ukuvimbela ukugqwala nokwandisa impilo yepayipi.Lokhu kubaluleke kakhuluishubhu yomugqa wamanzi, njengoba iqinisekisa ukuthi amanzi alethwayo ahlala ehlanzekile futhi engenalo ukungcola.

    Ngaphezu kokumelana nokugqwala, amapayipi ashiselwe i-arc angaphansi kwamanzi anikezela ngezakhiwo ezinhle kakhulu zemishini.Le ndlela ikhiqiza ama-welds afanayo kanye nepayipi eliqinile nelithembekile.Lokhu kubalulekile kumapayipi egesi yemvelo njengoba kuqinisekisa ukuthuthwa kwegesi yemvelo ngendlela ephephile futhi ephumelelayo ngaphandle kwengozi yokuvuza noma ukwehluleka.

    Ipayipi le-SSAW

    Ukwengeza, amapayipi ashiselwe i-arc angaphansi kwamanzi angaphansi ayakwazi ukumelana namazinga okushisa aphezulu kanye nezimo zemvelo.Lokhu kuzenza zilungele izinhlelo zokusebenza zasogwini kanye nasogwini ezingase zichayeke esimweni sezulu esibi nezimo zokusebenza.Ukuze uthole amashubhu olayini bamanzi, lokhu kuqina kuqinisekisa ukuthi amapayipi angakwazi ukuhambisa amanzi kahle ngaphandle kokuphazamisa ukusebenza.

    Enye inzuzo yokusebenzisa ipayipi elishiselwe i-arc elingaphansi kwamanzi ukuthi ingaphezulu layo libushelelezi futhi lihle.Lokhu kuzenza zibe inketho ekhangayo ekufakweni okungaphezulu nangaphansi komhlaba, njengoba kulula ukuzihlola nokuyinakekela.Ukwengeza, indawo ebushelelezi ye-weld inciphisa ukungqubuzana nokwehla kwengcindezi ngaphakathi kwepayipi, okusiza ukuthuthukisa ukusebenza kahle okuphelele kwezinhlelo zokulethwa kwegesi namanzi.

    Sengiphetha, ipayipi elishiselwe i-arc elicwiliswe kabili liyinketho enenzuzo kakhuluipayipi legesikanye ne-tubing yomugqa wamanzi.Inqubo yayo yokushisela ephumelelayo nengabizi, ehambisana nokugqwala, izakhiwo ezinhle kakhulu zemishini, ukuqina nobuhle, ikwenza kube yisinqumo sokuqala sokwakhiwa kwamapayipi.Kungakhathaliseki ukuthi athutha igesi yemvelo noma amanzi, la mapayipi anikeza amandla nokwethembeka okudingekayo ukuze asebenze ngokuphepha nangempumelelo.Ngokusobala, ipayipi elishiselwe i-arc elinezingqimba ezimbili liyimpahla ebalulekile emhlabeni wokwakhiwa kwamapayipi.
