    Izinzuzo zamapayipi we-welded welded ekwakhiweni kwegesi yemvelo

    Izinzuzo zamapayipi we-Weld Welded ku-Natural Gas Pipeline Ukwakhiwa kwesithombe esifakiwe
    • Izinzuzo zamapayipi we-welded welded ekwakhiweni kwegesi yemvelo
    • Izinzuzo zamapayipi we-welded welded ekwakhiweni kwegesi yemvelo

    Incazelo emfushane:

    Lapho kwakhiwa amapayipi wegesi wemvelo, izindlela zokukhethwa kwezinto ezibonakalayo nezindlela zokukhiqiza zibalulekile ekuqinisekiseni ukuphepha, ukwethenjwa kanye nokuphila isikhathi eside kwengqalasizinda. Enye yezixazululo ezivame kakhulu futhi ezisebenzayo emkhakheni ukusetshenziswa kwepayipi lensimbi eluhlaza okotshani, uhlobo lwepayipi elinenkani elinikeza izinzuzo eziningi zokudluliselwa kwegesi yemvelo.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

    Amapayipi we-welded we-welded akhiqizwa kusetshenziswa inqubo lapho imichilo yensimbi ilinyazwa futhi iqhutshwa khona ngokuqhubekayo ukwakha isimo sokulukama. Le ndlela ikhiqiza amapayipi aqinile, aqinile futhi aguqukayo afaneleka kahle ezidingweni zokuhamba kwegesi yemvelo.

    Enye yezinzuzo eziphambili zepayipi elivuthayo eSpiral iyisilinganiso sayo esiphakeme sokuqina kwesisindo. Lokhu kwenza kube kuhle ngamapayipi amabanga amade njengoba kungamelana nezingcindezi zangaphakathi nangaphandle ezisetshenziswe ngesikhathi sokuhamba kwegesi yemvelo ngaphandle kokuyekethisa ubuqotho bezemvelo. Ngaphezu kwalokho, inqubo ye-welding spiral iqinisekisa ukufana kobukhulu bodonga lwamapayipi, ngenyusa amandla alo kanye nokumelana noshintsho.

    Ngaphezu kwalokho, amapayipi ensimbi anezinwele ze-welded anokumelana okuhle kakhulu kokugqwala, okuyisici esibalulekile ngaphakathiIpayipi lemvelo lemveloukwakhiwa. Izakhiwo ezenzeka ngensimbi ezihlanganiswe nezimbozo ezithuthukile kanye nama-linings zenza la mapayipi amelana kakhulu nemiphumela yokulimazeka yegesi yemvelo kanye nokunye okungcolisayo okukhona emvelweni. Lokhu akugcini nje ngokunweba impilo yepayipi, futhi kunciphisa izidingo zokulungiswa kanye nezindleko ezihambisana nazo.

    Ngaphezu kwezakhiwo zayo zokuvimbela ezenziwa ngomshini kanye nokugqwala, ipayipi elivuthayo i-WELDED lilungele ukufakwa ezindaweni ezahlukahlukene zezwe nezimo zezemvelo. Ukuguquguquka kwayo kuvumela ukuqondisa okulula nokufaka ukufakwa okucindezelayo, okwenza kube inketho engabizi kakhulu yezindawo eziyinselele. Ngaphezu kwalokho, amalungu e-weldered amapayipi avunguza aqinile, aqinisekise ukuthi amapayipi atholakala kalula empilweni yakhe yonke.

    Enye inzuzo yepayipi elishajiwe liwukusebenza kwemali kwalo. Inqubo yokukhiqiza inika amandla okusebenzisa okuphezulu nokusetshenziswa okusebenzayo kwezinto ezisetshenziswayo ngentengo yokuncintisana uma iqhathaniswa nezinye izinto zepayipi. Ngaphezu kwalokho, ukuqina kanye nezidingo zokulungiswa okuphansi zosizo lwe-welded welded zisiza ukunciphisa izindleko zokuphila, okwenza kube ukukhetha okuqondakalayo kwezomnotho kwamaphrojekthi we-Pipelines yemvelo.

    Ngaphezu kwalokho, ukuvumelana nezimo kwamapayipi we-welded we-Work Lokhu kuguqulwa kuvumela ukwakheka kwamapayipi ukuthi kulungiswe izidingo ezithile zokusebenza, kuqinisekisa ukusebenza kahle kanye nokusebenza kahle.

    Ngokufingqa, ukusetshenziswa kweKuvunguza amapayipi ensimbiEkwakhiweni kwegesi yemvelo kunikeza izinzuzo eziningi, kufaka phakathi amandla aphezulu, ukumelana nokugqwala, ukuguquguquka kwezindleko kanye nokusebenza kwezindleko. Ngenxa yalokhu, kuhlala kungukukhetha kokuqala kochwepheshe bezimboni abafuna izixazululo ezithembekile, ezihlala isikhathi eside. Ngokuqamba izinzuzo ezingokwemvelo zepayipi elishiswe yi-welded, ababambe iqhaza bangaqinisekisa ukuthi ingqalasizinda yemvelo yemvelo isebenza ngokuphepha, ngempumelelo nangokuzinzile iminyaka ezayo.
