    Ukubaluleka Kwepayipi Le-Arc Elicwiliswe Emoyeni Ku-API 5L Line Pipe Carbon Pipe Welding

    Ukubaluleka Kwepayipi Le-Arc Elicwiliswe Emoyeni Kupayipi Lomugqa we-API 5L Ukushisela Ipayipi Lekhabhoni Isithombe Esivelele
    • Ukubaluleka Kwepayipi Le-Arc Elicwiliswe Emoyeni Ku-API 5L Line Pipe Carbon Pipe Welding

    Incazelo emfushane:

    Ipayipi Elihlanganisiwe Le-Arc Elihlanganisiwe Elihlanganisiwe Eliyindilinga (SSAW) idlala indima ebalulekile ekushiseni amapayipi ekhabhoni uma kukhulunywa ngokukhetha ipayipi elifanele lokusetshenziswa kwamapayipi omugqa we-API 5L. Le ndlela yokushiseni isetshenziswa kabanzi ekwakhiweni kwamapayipi kawoyela negesi ngenxa yenqubo yayo esezingeni eliphezulu nephumelelayo.


    Imininingwane Yomkhiqizo

    Amathegi Omkhiqizo

    Ukusetshenziswa kokushisela amapayipi ekhabhoni, ikakhulukazi ipayipi elihlanganisiwe le-spiral submited arc, kubalulekile ekuqinisekiseni ubuqotho besakhiwo kanye nokuthembeka kwaso.Ipayipi lomugqa we-API 5LLe ndlela yokushisela idala isibopho esingenamthungo nesihlala isikhathi eside phakathi kwamapayipi ekhabhoni, okudingekayo ukuze kumelwane nokucindezeleka okuphezulu kanye nezimo zemvelo ezinzima amapayipi abhekene nazo.

    Amashubhu e-arc angaphansi komhlaba akhiqizwa ngenqubo ekhethekile yokushisela lapho i-arc yokushisela ifakwa ngaphansi kwengubo yokugeleza. Lokhu kudala ukushisela okungenamthungo, kwekhwalithi ephezulu futhi kwandise ubude bepayipi. Ukusetshenziswa kwale ndlela yokushisela ekushiseni ipayipi lekhabhoni lepayipi lomugqa we-API 5L kuqinisekisa ukuxhumana okuqinile nokuhlala isikhathi eside okuhlangabezana nezidingo zemboni kawoyela negesi.

    Ngaphezu kwekhwalithi yokushisela, ipayipi le-SSAW linezinye izinzuzo eziningana ezenza libe yingxenye ebalulekile ekwakhiweni kwepayipi lomugqa we-API 5L. Umklamo ojikelezayo wepayipi unikeza ukuguquguquka okukhulu kanye nokuguquguquka, okwenza kube lula ukuwela izindawo ezahlukene kanye nezithiyo ngesikhathi sokwakhiwa kwepayipi.

    Ngaphezu kwalokho, amashubhu e-arc acwiliswe yi-spiral ayakwazi ukwamukela ububanzi obukhulu, okwenza abe ngcono ekuthuthweni kwenqwaba kawoyela negesi. Ikhono layo lokuphatha inqwaba yoketshezi ngenkathi igcina ubuqotho besakhiwo yenza kube ukukhetha okuthembekile kwezicelo zamapayipi omugqa we-API 5L.

    Izinqubo Zokushisela Amapayipi

    Enye inzuzo yamapayipi e-arc acwiliswe ngaphansi kwe-spiral ukuthi asebenza kahle kakhulu. Inqubo yokushisela ephumelelayo kanye nekhono lokukhiqiza amapayipi amakhulu ngobukhulu kwenza kube yisisombululo esisebenza kahle kakhulu sokwakhiwa kwamapayipi. Lokhu kubaluleke kakhulu embonini kawoyela negesi, lapho ukwakhiwa nokugcinwa kwamapayipi kungaba yizindleko ezinkulu.

    Ukusetshenziswa kwamapayipi ahlanganisiwe e-spiral ac welded ku-API 5L line pipe carbon pipe welding kubalulekile ekuqinisekiseni ubuqotho nokuthembeka kwephayiphi. Ukushisela kwayo kwekhwalithi ephezulu, ukuguquguquka kanye nokusebenza kahle kwezindleko kwenza kube yingxenye ebalulekile yokwakhiwa kwamapayipi kawoyela negesi.

    Ngamafuphi, ipayipi le-SSAW lidlala indima ebalulekile ekushiseni amapayipi ekhabhoni ekusetshenzisweni kwamapayipi omugqa we-API 5L. Ukushiseni kwalo kwekhwalithi ephezulu, ukuguquguquka kanye nokusebenza kahle kwezindleko kwenza kube kuhle kakhulu ekwakhiweni kwamapayipi embonini kawoyela negesi. Ngokukhetha ipayipi le-SSAW, inkampani ingaqinisekisa ubuqotho besakhiwo kanye nokuthembeka kwepayipi layo lomugqa we-API 5L, okuholela ohlelweni lwamapayipi olusebenza kahle noluthembekile.
