    Incazelo emfushane:

    Uyemukelwa ku-cangzhou Spiral Steel Pipe Pipe Colo, Ltd, umenzi owaziwayo nomhlinzeki wekhwalithi ephezulu ye-Weld Carbon Steel. Inkampani yethu iyaziqhenya ngokusebenzisa ubuchwepheshe obusezingeni eliphakeme obuphakathi be-arlding obuqinisekisa ukukhiqizwa kwamapayipi aphezulu we-notch Spiral Seam ngezinhlobo ezahlukahlukene.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

    Emhlabeni we-Plumbing, kunezindlela ezahlukahlukene zokwakha nezinto zokwakha. Indlela ethandwayo yokujoyina amapayipi i-Welding efakwe kabili engaphansi kwe-arc (Dsaw). Le ndlela ivame ukusetshenziswa kugesi nemigqa yamanzi, futhi ngesizathu esihle. Kule bhulogi sizohlola izinzuzo zokusebenzisai-arc efakwe kabili efakwe i-arcipayipi kulezi zinhlelo zokusebenza.

    Ukuhlolwa kweHydrostatic

    Incazelo Yomkhiqizo1

    Ipayipi lizomelana nokuhlolwa kwe-hydrostatic ngaphandle kokuvuza ngomthungo we-weld noma umzimba wepayipi
    Ama-pailers akudingeki ahlolwe ngokuqinile, uma nje izingxenye zepayipi elisetshenziselwa ukumaka amajoyidi ahlolwe ngempumelelo ngempumelelo yokusebenza.

    I-arlding yaphansi kwe-arc

    Okokuqala, i-welding efakwe kabili yangemuva kwe-ARC iyindlela esebenza kahle futhi enomnotho yokujoyina amapayipi. Le nqubo ifaka ukwakha i-weld ngokufaka ipayipi ku-flanur flux usebenzisa ama-arcs amabili e-welding. Lokhu kudala i-weld eqinile futhi eqinile engamelana nengcindezi ephezulu kanye nokungezwani, okwenza kube kuhle kakhulu ngemigqa yegesi nemigqa yamanzi.

    Enye yezinzuzo eziphambili zepayipi elifakwe kabili le-arc I-granurar flux esetshenzisiwe kule nqubo ye-welding idala ungqimba oluvikelayo phezu kwe-weld, isiza ukuvikela ukonakala nokunweba impilo yepayipi. Lokhu kubaluleke kakhuluIshubhu Line Line, njengoba iqinisekisa ukuthi amanzi alethwa ahlala ehlanzekile futhi engenakho ukungcoliseka.

    Ngaphezu kokumelana nokugqwala, amapayipi we-arc afakwe kabili angenawo angenawo anikela nge-mehendi anikeza izakhiwo ezinhle kakhulu zemishini. Le ndlela ikhiqiza ama-welds afanayo kanye nepayipi eliqinile nelithembekile. Lokhu kubalulekile kumapayipi wegesi wemvelo njengoba kuqinisekisa ukuthuthwa okuphephile nokusebenzayo kwegesi yemvelo ngaphandle kwengozi yokuvuza noma ukwehluleka.

    Ipayipi le-SSAW

    Ngokwengeziwe, amapayipi we-welded angeniswe kabili angenawo angenawo akwazi ukubekezelela amazinga okushisa aphezulu nezimo zemvelo. Lokhu kubenza balungele izinhlelo zokusebenza ze-Onshore nase-Offshore ezingavezwa isimo sezulu esibi kanye nezimo zokusebenza. Nge-tubing yomugqa wamanzi, lokhu kuqina kuqinisekisa ukuthi amapayipi angahambisa amanzi kahle ngaphandle kokuyekethisa ukusebenza.

    Enye inzuzo yokusebenzisa ipayipi elifakwe kabili le-arc efakwe kabili le-arc Lokhu kubenza babe nenketho ekhangayo yenhla- nangaphansi-ngaphansi komhlaba, ngoba kulula ukuhlola nokugcina. Ngaphezu kwalokho, indawo ebushelelezi ye-weld inciphisa ukungqubuzana nokucindezela kwehla ngaphakathi kwepayipi, kusiza ukuthuthukisa ukusebenza kahle kwegesi nezinhlelo zokulethwa kwamanzi.

    Ekuphetheni, ipayipi elifakwe kabili le-arc efakwe i-arc liwukukhetha okuhle kakhuluIpayipi legesi Linenamashubhu omugqa wamanzi. Inqubo ye-welding ye-welding esebenza kahle futhi engabizi, ehambisana nokumelana nokugqwala, izakhiwo ezinhle kakhulu zemishini, ukuqina kanye nama-aesthetics, kwenze isinqumo sokuqala sokwakhiwa kwamapayipi. Noma ngabe ukuthutha igesi noma amanzi wemvelo, la mapayipi ahlinzeka ngamandla nokwethenjwa okudingekayo ukusebenza ngokuphephile nangendlela efanele. Ngokusobala, ipayipi elisezingeni eliphansi eliphansi eliphansi le-arc
