    Imibhobho yentsimbi ye-SSAWzenziwe ngeekhoyili zentsimbi strip njengezinto ekrwada, extruded kwiqondo lobushushu rhoqo, kwaye welding yinkqubo yokuwelda oluzenzekelayo kabini-amacala-macala aphantsi arc.Le teknoloji yokuvelisa imveliso iqinisekisa amanqanaba aphezulu okuchaneka kunye nokuqina, okwenza imibhobho yethu ibe yinto efanelekileyo kwizicelo zomgca wamanzi aphantsi komhlaba.

    Umbhobho woMda waManzi angaphantsi komhlaba

    Intliziyo leumbhobho wentsimbi ejikelezayoluyilo lwayo olulodwa olujiyileyo.Intsimbi yomcu ifakwe kwisixhobo sombhobho odityanisiweyo kwaye ngokuthe ngcembe iqengqeleke ngama-roller amaninzi ukwenza umbhobho ojikelezayo ongenanto kunye nesithuba sokuvula.Iyakwazi ukulungelelanisa inani lokunciphisa i-roller extrusion, kwaye i-gap ye-weld inokulawulwa phakathi kwe-1-3mm ukuqinisekisa uxhulumaniso olungenamthungo kunye noluqinileyo.Ukongezelela, zombini iziphelo zomdibaniso odibeneyo zigungxulwe ngokugqibeleleyo, zibonelela ngokugqibeleleyo.

    Imibhobho yentsimbi ye-SSAW ineempawu ezininzi ezahlulayo kwimibhobho yentsimbi yemveli.Isakhiwo sayo esijikelezayo sinamandla amakhulu kunye nokuchasana nemikhosi yangaphandle, iqinisekisa ukhuseleko kunye nokuthembeka kwenkqubo yokuhanjiswa kwamanzi.Ukongezelela, inkqubo ye-welding ephezulu iqinisekisa ukuba amajoyina avuza kwaye anqande ukukhupha kwamanzi okanye ukungcola.Ngolwakhiwo olomeleleyo kunye noqhagamshelo olukhuselekileyo, lo mbhobho uqinisekisa ukusebenza okuhlala ixesha elide kunye nokunciphisa iimfuno zokugcinwa, okwenza kube isisombululo esinendleko kuyo nayiphi na iprojekthi yomzila wamanzi aphantsi komhlaba.

    a.Indlela ye-deoxidation yonyulwa ngolu hlobo lulandelayo:

    FF: Intsimbi ebulewe ngokupheleleyo equlethe izinto ezibophelelayo zenitrogen ngokwezixa ezaneleyo zokubopha initrogen ekhoyo (umz. min. 0,020 % iyonke iAl okanye i-0,015 % enyibilikayo iAl).

    b.Ixabiso eliphezulu le-nitrogen alisebenzi ukuba ukubunjwa kweekhemikhali kubonisa ubuncinane be-Al umxholo we-0,020 % kunye nomlinganiselo we-Al/N ubuncinane we-2: 1, okanye ukuba kukho ezinye izinto ezaneleyo ze-N-binding.Izinto ezibophelelayo ze-N ziya kubhalwa kuXwebhu loHlolo.

    Le mveliso ikhethekileyo yenzelwe ukuhlangabezana neemfuno ezahlukeneyo zeshishini.Nokuba kwakha unikezelo lwamanzi lukamasipala kunye neenkqubo zothutho logutyulo okanye ukuthutha irhasi yendalo kunye ne-oyile kumgama omde, imibhobho edityanisiweyo ye-arc edityanisiweyo lukhetho lokuqala.Ukuguquguquka kwayo kunabela kwiinkqubo zeemfumba zemibhobho, ukubonelela ngozinzo olungenakulinganiswa kunye nomthamo womthwalo.Ngamandla abo aphezulu kunye nokuthembeka, imibhobho yethu idlula zonke izinto ezilindelekileyo malunga nokusebenza kunye nokuphila ixesha elide.

    ECangzhou Spiral Steel Pipe Group Co., Ltd., ukuzibophelela kwethu ekugqweseni akugungqi.Ngeminyaka yamava oshishino kunye nobuchule, siyazingca ngokuzisa iimveliso ezisemgangathweni ezihlangabezana nemigangatho ephezulu.Amaziko ethu okuvelisa akumgangatho ophezulu kunye neenkqubo ezingqongqo zokulawula umgangatho ziqinisekisa ukuba yonke i-spiral submerged arc welded steel pipe eshiya umzi-mveliso iphezulu kakhulu.

    Umbhobho we-SSAW

    Ngokufutshane, umbhobho wentsimbi ojikelezileyo we-arc odityanisiweyo uya kutshintsha ushishino lwemibhobho yamanzi angaphantsi komhlaba.Ibandakanya ulwakhiwo oluphezulu, amajoyina angavuziyo kunye namandla aphezulu, lo mbhobho lolona khetho lubalaseleyo kuyo nayiphi na iprojekthi yokuhambisa amanzi.Kholelwa ukuba iCangzhou Spiral Steel Pipe Group Co., Ltd. inokukunika esona sisombululo silungileyo ukuhlangabezana neemfuno zakho.Amava ngekamva leenkqubo zemibhobho yamanzi aphantsi komhlaba ngombhobho wentsimbi we-SSAW.
