    Ukubaluleka kwe-Spiral Submerged Arc Pipe ku-API 5L Line Pipe Carbon Pipe Welding

    Ukubaluleka kwe-Spiral Submerged Arc Pipe ku-API 5L Line Pipe Carbon Pipe Welding Isithombe Esifakiwe
    • Ukubaluleka kwe-Spiral Submerged Arc Pipe ku-API 5L Line Pipe Carbon Pipe Welding

    Incazelo emfushane:

    Ipayipi Elishiselwe I-Spiral Submerged Arc (SSAW) idlala indima ebalulekile ekushiseleni ipayipi lekhabhoni uma kuziwa ekukhetheni ipayipi elilungile lezinhlelo zokusebenza zepayipi lomugqa we-API 5L.Le ndlela yokushisela isetshenziswa kakhulu ekwakhiweni kwamapayipi kawoyela negesi ngenxa yekhwalithi ephezulu, inqubo ephumelelayo.


    Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    Ukusetshenziswa kwe-carbon pipe welding, ikakhulukazi i-spiral submerged arc welded pipe, kubalulekile ekuqinisekiseni ubuqotho besakhiwo kanye nokwethembeka.Ipayipi lomugqa we-API 5L.Le ndlela yokushisela idala isibopho esingenamthungo nesihlala isikhathi eside phakathi kwamashubhu ekhabhoni, okudingekayo ukuze umelane nezingcindezi eziphezulu kanye nezimo zemvelo ezinzima amapayipi abhekana nazo.

    Amashubhu e-Spiral angaphansi kwamanzi akhiqizwa ngenqubo yokushisela ekhethekile lapho i-arc yokushisela icwiliswa ngaphansi kwengubo yokuguquguquka.Lokhu kudala i-weld engenamthungo, yekhwalithi ephezulu futhi kwandisa ubude bepayipi.Ukusetshenziswa kwale ndlela yokushisela ekushiseleni ipayipi le-carbon ye-API 5L linepayipi kuqinisekisa ukuxhumana okuqinile nokuqinile okuhlangabezana nezidingo zemboni kawoyela negesi.

    Ngaphezu kwekhwalithi yokushisela, ipayipi le-SSAW linezinye izinzuzo ezimbalwa ezenza kube ingxenye ebalulekile ekwakhiweni kwepayipi lomugqa we-API 5L.Idizayini ejikelezayo yepayipi inikeza ukuguquguquka okukhulu nokuguquguquka, okwenza kube lula ukunqamula izindawo nezithiyo ezihlukahlukene ngesikhathi sokwakhiwa kwamapayipi.

    Ngaphezu kwalokho, amashubhu e-arc angaphansi kwamanzi ayi-spiral ayakwazi ukuthwala ama-diameter amakhulu, okuwenza alungele ukuthutha umthamo omkhulu kawoyela negesi.Ikhono layo lokuphatha umthamo omkhulu woketshezi ngenkathi igcina ubuqotho besakhiwo ikwenza kube ukukhetha okuthembekile kwezinhlelo zokusebenza zepayipi lomugqa we-API 5L.

    Izinqubo zokushisela amapayipi

    Enye inzuzo yamashubhu e-arc angaphansi kwamanzi ayi-spiral ukusebenza kahle kwawo kwezindleko.Inqubo yokushisela ephumelelayo kanye nekhono lokukhiqiza amapayipi amakhulu obubanzi kwenza kube yisixazululo esingabizi kakhulu sokwakhiwa kwamapayipi.Lokhu kubaluleke kakhulu embonini kawoyela negesi, lapho ukwakhiwa nokugcinwa kwamapayipi kungaba yizindleko ezinkulu.

    Ukusetshenziswa kwamapayipi ashiselwe i-arc angaphansi kwe-arc ashiselwe ku-API 5L wepayipi le-carbon pipe welding kubalulekile ekuqinisekiseni ubuqotho nokuthembeka kwepayipi.Ukushisela kwayo okusezingeni eliphezulu, ukuguquguquka kanye nokusebenza kahle kwezindleko kuyenza ibe yingxenye ebalulekile yokwakhiwa kwamapayipi kawoyela negesi.

    Kafushane, ipayipi le-SSAW lidlala indima ebalulekile ekushiseleni kwepayipi lekhabhoni kuzicelo zepayipi lomugqa we-API 5L.Ukushisela kwayo okusezingeni eliphezulu, ukuguquguquka kanye nokusebenza kahle kwezindleko kuyenza ilungele ukwakhiwa kwamapayipi embonini kawoyela negesi.Ngokukhetha ipayipi le-SSAW, inkampani ingaqinisekisa ubuqotho besakhiwo nokuthembeka kwepayipi layo lomugqa we-API 5L, ekugcineni kuphumele ohlelweni lwamapayipi olusebenza kahle futhi oluthembekile.
