    IINGXAKI ZOKUSETYENZISELWA KWE-SPIRAL I-ARC exhonywe kwimibhobho yentsimbi ye-welc yensimbi yemibhobho engaphantsi komhlaba

    IINGXAKI ZOKUSETYENZISELWA KWE-SPIAL ERCY PEDED PALED EPHEPHA ZEEMPAHLA ZAMANZI AMANZI AMANZI AMANZI
    • IINGXAKI ZOKUSETYENZISELWA KWE-SPIRAL I-ARC exhonywe kwimibhobho yentsimbi ye-welc yensimbi yemibhobho engaphantsi komhlaba

    Inkcazo emfutshane:

    Xa ibeka imigca yamanzi engaphantsi komhlaba, kubalulekile ukukhetha uhlobo olufanelekileyo lwe-pime ukuqinisekisa ukuqina kunye nobomi obude. Ukhetho oludumileyo lwemigca yamanzi engaphantsi komhlaba ngumbhobho owenziwe nge-weldil welding, owaziwa njengombhobho wentsimbi ye-SSAW.

    Iimpawu zeMveliso

     I-SSAW PIP yentsimbiLuhlobo lwe-pieral Arc of Peped Peper esetyenziswe rhoqo kwizicelo ezahlukeneyo, kubandakanya imigca yamanzi aphantsi komhlaba. Inkqubo yayo eyahlukileyo ye-welding ivelisa imibhobho emikhulu ye-Deameter enobunzima obungaguqukiyo, owenza ilungele ukuthuthwa kwamanzi aphantsi komhlaba.

    Enye yezona zinto zibalulekileyo zokusebenzisa i-Picral Arc Proped imibhobho yentsimbi yemigca yamanzi aphantsi komhlaba ngamandla ayo aphezulu kunye nokuqina. Inkqubo yokwehla ye-weldiral idala umbhobho onamandla nowuthembekileyo onokuthi akwazi ukumelana noxinzelelo kunye nobunzima bokungcwatywa phantsi komhlaba. Amandla alulekileyo ekuthinteleni ukuvuza nokuqinisekisa ukuthembeka okwexesha elide kwimibhobho yamanzi.

    Ukongeza, umbhobho wentsimbi ye-SSA kukunganyangeki ukuba usuleleke, usenze ukhetho oluhle lwezicelo eziphantsi komhlaba apho imibhobho iveze ukufuma kunye nezinye izinto zokusingqongileyo. Oku kuxhathisa okususelwayo kunceda ukwandisa ubomi bemibhobho yakho kwaye kunciphisa isidingo sokulungiswa rhoqo kunye nokulungiswa.

    Umbhobho womgca wamanzi angaphantsi komhlaba

    Elinye ingenelo ekusebenziseni i-arc engaphantsi kwe-pied ping wensimbi yentsimbi yemigca yamanzi aphantsi komhlaba kukutshintsha kwayo kunye nokuziqhelanisa. Inkqubo yokuphucula i-welding inokuvelisa imibhobho yoo-Diemeter obahlukeneyo, zenza ilungele iintlobo ezahlukeneyo zemibhobho yamanzi. Ukongeza, ukuguquguquka kombhobho we-SSAW wenza kube lula ukufaka kwaye kusebenza, ngakumbi kwiindawo ezinendawo yokucela umngeni okanye imiqobo.

    a. Indlela ye-Deaxotion ichongwe ngolu hlobo lulandelayo:

    I-FF: Intsimbi egcinwe ngokupheleleyo i-nitrogen ebophelelayo kwizixa ezaneleyo zokubopha initrogen (umz. I-0,020% ye-al).

    b. Elona xabiso liphezulu le-nitrogen alisebenzi ukuba ukubekwa kwekhemikhali kubonisa i-0,020% ye-al / n i-2: 1, okanye ukuba izinto ezaneleyo ze-N-Bing zikhona. Izinto ezibophelelayo ziya kurekhodwa kuxwebhu lovavanyo.

    Ukongeza kumandla, ukuqina, kunye nokuguquguquka, i-Picmaral Arc i-Piped Pipe ye-Weld ye-Welc ye-Welc ye-Wels isebenza nezinye iintlobo zombhobho. Inkqubo ye-Welting ye-SPILL inciphisa iindleko zemveliso, zenza ukhetho oluthe kratya lweeprojekthi ezinkulu zemibhobho yamanzi. Ukuqina kwexesha elide kunye neemfuno zolondolozo olusezantsi lombhobho we-SSAW ye-SSAW ikwanegalelo kulondolozo lweendleko ngokubanzi ngobomi bomgca wamanzi.

    I-SSAW PIP

    Lilonke, zininzi izibonelelo zokusebenzisa umbhobho wentsimbi ye-welc weldar wensimbi yemigca yomhlaba, kubandakanya amandla aphezulu, ukuqina, ukungqubana kwe-corrosion, kunye nokusebenza ngendleko. Ezi mpawu zenza ukhetho oluthembekileyo nolusebenzayo kwiingenelo ezingaphantsi komhlaba, nokuba kuseza kwizibonelelo zoomasipala, izicelo zeshishini, okanye iinjongo zezolimo.

    Ngesishwankathelo, xa kufikwa ekukhetheni umbhobho obalaseleyoImigca engaphantsi komhlaba, I-Spiral Arc ephantsi i-arc yensimbi yentsimbi yesona sikhetho silungileyo. Ulwakhiwo lwayo lwe-spiral-beldiy lubonelela ngamandla, ukuqina kwendlela yokunyanzelwa kwe-corrosion efunekayo kwintsebenzo yexesha elide, ngelixa uguqukayo kunye nokusebenza kwendleko kwenza ukuba kube yindlela enomdla yeempawu zawo bonke ubungakanani. Ngokukhetha i-SPIRAL i-arc i-arc i-pipe yentsimbi yentsimbi, unokuqinisekisa ukuthembeka kunye nokuhlala kwezinto zobomi, ukunika uxolo lwengqondo kunye nokuzithemba kwinkqubo yakho yamanzi.
