    Imibhobho yentsimbi ye-SSAWZenziwe ngee-strip steel coils njengezinto eziluhlaza, zikhutshwa kubushushu obungaguqukiyo, kwaye zidityaniswa ngenkqubo yokuwelda ye-arc engaphantsi kwamanzi ezenzekelayo enamacala amabini. Le teknoloji intsha yemveliso iqinisekisa amanqanaba aphezulu okuchaneka nokuqina, okwenza imibhobho yethu ilungele ukusetyenziswa kwemigca yamanzi angaphantsi komhlaba.

    Umbhobho Womjelo Wamanzi Ongaphantsi Komhlaba

    Intliziyo yale ntoumbhobho wentsimbi ejikelezayoluyilo lwayo oluyi-spiral olukhethekileyo. Intsimbi yestrip ifakwa kwisixhobo sepayipi edibeneyo kwaye igoqwe kancinci ngeerola ezininzi ukuze yenze ityhubhu ejikelezayo engenanto enesithuba sokuvula. Inokukwazi ukulungisa ubungakanani bokunciphisa i-roller extrusion, kwaye isithuba se-weld singalawulwa phakathi kwe-1-3mm ukuqinisekisa uqhagamshelo olungenamthungo noluqinileyo. Ukongeza, zombini iziphelo zejoyinti edibeneyo zithambile ngokugqibeleleyo, zibonelela ngokugqitywa okugqibeleleyo.

    Iipayipi zentsimbi ze-SSAW zineempawu ezininzi ezizahlula kwiipayipi zentsimbi zemveli. Ulwakhiwo lwayo olujikelezayo lunamandla agqwesileyo kunye nokumelana namandla angaphandle, okuqinisekisa ukhuseleko kunye nokuthembeka kwenkqubo yokuhambisa amanzi. Ukongeza, inkqubo yokuwelda esemgangathweni ophezulu iqinisekisa ukuba amalungu ayavuthuza kwaye ithintela ukuvuza kwamanzi okanye ungcoliseko. Ngokwakhiwa kwayo okuqinileyo kunye noqhagamshelo olukhuselekileyo, le pipe iqinisekisa ukusebenza okuhlala ixesha elide kwaye inciphisa iimfuno zokugcinwa, okwenza ibe sisisombululo esingabizi kakhulu kuyo nayiphi na iprojekthi yomgca wamanzi angaphantsi komhlaba.

    a. Indlela yokususa ioksijini ichazwe ngolu hlobo lulandelayo:

    FF: Intsimbi ebulewe ngokupheleleyo equlethe izinto zokubopha initrogen ngobuninzi obaneleyo ukubopha initrogen ekhoyo (umz. ubuncinci be-0,020% iyonke ye-Al okanye i-0,015% ye-Al enyibilikayo).

    b. Ixabiso eliphezulu le-nitrogen alisebenzi ukuba ukwakheka kweekhemikhali kubonisa umxholo opheleleyo we-Al ongama-0,020% kunye nomlinganiselo ophantsi we-Al/N oyi-2:1, okanye ukuba kukho ezinye izinto ezaneleyo zokubopha i-N. Izinto zokubopha i-N mazirekhodwe kuXwebhu loHlolo.

    Le mveliso ibalaseleyo yenzelwe ukuhlangabezana neemfuno ezahlukeneyo zoshishino. Nokuba yakha iinkqubo zokuhambisa amanzi zikamasipala kunye neenkqubo zothutho lwelindle okanye ukuthutha igesi yendalo kunye neoyile kumgama omde, iipayipi ezifakwe i-spiral submerged arc welded zezona zikhethwa kuqala. Ukuguquguquka kwayo kufikelela kwiinkqubo zeepayipi, zibonelela ngozinzo olungenakuthelekiswa nanto kunye nomthamo wokuthwala umthwalo. Ngamandla azo aphezulu kunye nokuthembeka, iipayipi zethu zidlula zonke izinto ezilindelweyo ngokubhekiselele ekusebenzeni nasekuphileni ixesha elide.

    KwiCangzhou Spiral Steel Pipe Group Co., Ltd., ukuzibophelela kwethu ekugqweseni akugungqi. Ngamava namava amaninzi kushishino, siyazingca ngokubonelela ngeemveliso ezisemgangathweni ezihlangabezana nemigangatho ephezulu. Izixhobo zethu zokwenza izinto ezisemgangathweni ophezulu kunye neenkqubo zokulawula umgangatho ezingqongqo ziqinisekisa ukuba yonke imibhobho yentsimbi edityaniswe ne-arc ephuma kumzi-mveliso ikumgangatho ophezulu.

    Umbhobho we-SSAW

    Ngamafutshane, umbhobho wentsimbi ojikelezileyo ojikelezileyo ojikelezileyo ojikelezileyo uza kutshintsha ishishini lemibhobho yamanzi angaphantsi komhlaba.
