Longitudinal Submerge-arc Welded imibhobho kamsinyane LSAW umbhobho luhlobo umbhobho wentsimbi umthungo welding ogama longitudinally parallel kumbhobho wentsimbi, kunye izinto ekrwada ipleyiti yentsimbi, ngoko ubukhulu bodonga lwemibhobho LSAW kunokuba nzima kakhulu umzekelo 50mm. , ngelixa i-diameter yangaphandle ilinganiselwe kwi-1420mm eyona nto iphezulu.Umbhobho we-LSAW unenzuzo yenkqubo yokuvelisa elula, ukusebenza kakuhle kwemveliso, ixabiso eliphantsi.
Umbhobho we-Arc Welded (DSAW) ophindwe kabini luhlobo lombhobho wentsimbi ojiyileyo wokuwelda owenziwe ngentsimbi yekhoyili njengemathiriyeli ekrwada, ehlala ishushu i-extrusion kwaye idityaniswe yinkqubo ye-arc ezenzekelayo enamacala amabini antywiliselwe phantsi.Ngoko ubude obunye bombhobho we-DSAW bunokuba yi-40meters ngelixa ubude obunye bombhobho we-LSAW buzimitha ezili-12 kuphela.Kodwa ubuninzi bodonga lwemibhobho ye-DSAW bunokuba yi-25.4mm kuphela ngenxa yokukhawulelana kweekhoyili ezishushu ezishushu.
Uphawu olubalaseleyo lombhobho wentsimbi ejikelezayo kukuba idiameter yangaphandle ingenziwa ibe nkulu kakhulu, iCangzhou Spiral Steel Pipes Group Co.ltd inokuvelisa imibhobho emikhulu edayamitha enedayamitha yangaphandle eyi-3500mm eyona iphezulu.Ngethuba lenkqubo yokuqulunqa, i-coil yensimbi ikhubazekile ngokulinganayo, uxinzelelo olushiyekileyo luncinci, kwaye umphezulu awukhatywanga.Umbhobho wentsimbi ecociweyo unoguquko olukhulu kuluhlu lobungakanani bobubanzi kunye nobukhulu bodonga, ngakumbi kwimveliso yomgangatho ophezulu, umbhobho omkhulu wodonga, kunye nedayamitha encinci kunye nombhobho wokutyeba kodonga olukhulu, oluneenzuzo ezingenakuthelekiswa nezinye iinkqubo.Iyakwazi ukuhlangabezana neemfuno ezininzi zabasebenzisi kwiinkcukacha zemibhobho yentsimbi ejikelezayo.Inkqubo yokudibanisa i-arc enecala eliphindwe kabini iyakwazi ukuqonda i-welding kwindawo engcono kakhulu, engelula ukuba ibe neziphene ezifana nokungahambi kakuhle, ukuphambuka kwe-welding kunye nokungena okungaphelelanga, kwaye kulula ukulawula umgangatho we-welding.Nangona kunjalo, xa kuthelekiswa nombhobho womthungo othe tye kunye nobude obufanayo, ubude be-weld bunyuka nge-30 ~ 100%, kwaye isantya sokuvelisa siphantsi.
