I-DSAW(Ipayipi elishiselwe i-arc elinezinhlangothi ezikabili)izici: inqubo yokukhiqiza ipayipi ehlanganisiwe ilula, ukusebenza kahle okuphezulu, izindleko eziphansi, ukuthuthukiswa okusheshayo.Amandla wepayipi elishiselwe elivunguzayo ngokuvamile liphakeme kunepayipi le-dsaw futhi linganciphisa ukukhiqizwa kwe-billet yepayipi elikhulu lobubanzi, ungasebenzisa ububanzi obufanayo bokukhiqizwa kwe-billet yamadayimitha ahlukene wepayipi.Nokho, uma kuqhathaniswa nobude obufanayo bepayipi lomthungo oqondile, ubude be-Weld bukhuphuke ngo-30 kuya ku-100%, kanye nezinga lokukhiqiza eliphansi.

I-DSAW(i-Double-side spiral submerged arc welded pipe) isetshenziswa kabanzi kugesi yemvelo, uphethiloli, amakhemikhali, ugesi, ukufudumeza, amanzi, ukufudumeza umusi, i-hydropower penstock, amandla ashisayo, amanzi namanye amapayipi amabanga amade, ukunqwabelanisa, ukudonsa, amabhuloho. , insimbi neminye imikhakha yobunjiniyela.
