DSAW(Umbhobho odityanisiweyo ophindwe kabini we-arc odityanisiweyo)iimpawu: inkqubo yokuvelisa umbhobho odibeneyo ilula, ukusebenza kakuhle, ixabiso eliphantsi, uphuhliso olukhawulezayo.Amandla ombhobho we-spiral welded ngokubanzi uphezulu kunombhobho we-dsaw kwaye unokunciphisa imveliso ye-billet yombhobho omkhulu wedayamitha, ungasebenzisa ububanzi obufanayo bemveliso ye-billet yeedamitha ezahlukeneyo zombhobho.Nangona kunjalo, xa kuthelekiswa nobude obufanayo bombhobho womthungo othe tye, ubude be-Weld bunyuke nge-30 ukuya kwi-100%, kunye nezinga lokuvelisa eliphantsi.

I-DSAW (i-Double-side spiral submerged arc welded pipe) isetyenziswa kakhulu kwirhasi yendalo, i-petroleum, iikhemikhali, umbane, ukufudumeza, ukukhupha amanzi, ukufudumeza umphunga, i-hydropower penstock, amandla ashushu, amanzi kunye neminye imibhobho yomgama omde, ukufumba, ukudiliza, iibhulorho. , intsimbi kunye nezinye iinkalo zobunjineli.
