Kwintsimi yeumbhobho we-oyile kunye negesis, ukusetyenziswa kwemibhobho ye-spiral welded iya isiba yinto eqhelekileyo.Ikwaziwa ngokuba ngumbhobho womgca werhasi, umbhobho wesarha, kunye nombhobho weoyile nerhasi, le mibhobho iguquguqukayo yenziwa kusetyenziswa ubuchule bokuwelda obukhethekileyo obubonelela ngeenzuzo ezininzi kuthutho lweoyile, igesi yendalo, kunye nolunye ulwelo.Kule bhlog, siza kuphonononga ukuguquguquka kwemibhobho ye-spiral welded kwaye kutheni ilukhetho lokuqala kwiiprojekthi ezininzi zemibhobho.
