Iipayipi ezidityanisiweyo ze-Longitudinal Submerge-arc kungekudala zepayipi ye-LSAW luhlobo lombhobho wentsimbi one-welding seam ehambelana nombhobho wentsimbi, kwaye izinto ezisetyenzisiweyo ziyipleyiti yentsimbi, ngoko ke ubukhulu bodonga lweepayipi ze-LSAW bunokuba nzima kakhulu umzekelo i-50mm, ngelixa ububanzi bangaphandle bunqunyelwe kwi-1420mm. Umbhobho we-LSAW unenzuzo yenkqubo elula yokuvelisa, ukusebenza kakuhle kwemveliso, kunye neendleko eziphantsi.
Umbhobho we-Double Submerged Arc Welded (DSAW) luhlobo lombhobho wentsimbi yomthungo we-spiral welding owenziwe nge-coil yentsimbi njengezinto eziluhlaza, odla ngokufudumeza ukukhupha kwaye udityaniswe ngenkqubo yokudityanisa i-arc engaphantsi komhlaba ezenzekelayo. Ngoko ke ubude obunye bombhobho we-DSAW bunokuba yi-40meters ngelixa ubude obunye bombhobho we-LSAW buziimitha ezili-12 kuphela. Kodwa ubukhulu bodonga obuphezulu beembhobho ze-DSAW bunokuba yi-25.4mm kuphela ngenxa yokunqongophala kweekhoyili ezishushu ezijikelezileyo.
Uphawu olubalaseleyo lombhobho wentsimbi ejikelezayo kukuba ububanzi bangaphandle bunokwenziwa bukhulu kakhulu, iCangzhou Spiral Steel Pipes Group Co.ltd inokuvelisa imibhobho emikhulu enobubanzi bangaphandle obuyi-3500mm. Ngexesha lenkqubo yokwenza, ikhoyili yentsimbi iyaguquguquka ngokulinganayo, uxinzelelo olushiyekileyo luncinci, kwaye umphezulu awukrwelwa. Umbhobho wentsimbi ejikelezayo ocutshungulwayo unokuguquguquka okukhulu kuluhlu lobukhulu bobubanzi kunye nobukhulu bodonga, ngakumbi ekuvelisweni kombhobho omkhulu, ophakamileyo, kunye nobubanzi obuncinci kunye nombhobho omkhulu wobukhulu bodonga, onezibonelelo ezingenakuthelekiswa nezinye iinkqubo. Ingahlangabezana neemfuno ezingaphezulu zabasebenzisi kwiinkcazo zembhobho yentsimbi ejikelezayo. Inkqubo yokuwelda ye-arc engaphantsi komhlaba enamacala amabini inokwenza ukuwelda kwindawo efanelekileyo, ekungekho lula ukuba neziphene ezifana nokungalungelelani, ukuphambuka kokuwelda kunye nokungena okungaphelelanga, kwaye kulula ukulawula umgangatho wokuwelda. Nangona kunjalo, xa kuthelekiswa nombhobho othe tye womthungo onobude obufanayo, ubude bokuwelda buyanda ngama-30 ~ 100%, kwaye isantya semveliso siphantsi.
