Liphaephe tsa HSAW (spiral submerged arc welded pipe), ke mabe a tšepe e kolobisitsoeng, 'me e kobeha ho latela spiral, othomathike ka tlas'a metsi arc welding e etsoang ka har'a seam le seam e ka ntle e kolobisitsoeng ka phala ea tšepe ea seam (e tsejoang hape e le spiral welded pipe). , peipi ea spiral, phala ea tšepe ea spiral).Ha e le mabaka a latelang, e sebelisoa haholo ha ho etsoa phala e kholo ea tšepe ea bophara:
1) ho fetola angle sebopeho, o ka sebelisa e tšoanang bophara hlobolisa tlhahiso mefuta e fapaneng ya calibres tšepe phala;
2) hobane ke ho kheloha ho tsoelang pele, bolelele ba bolelele ba phala ea tšepe ha bo na moeli;
3) ho ajoa ha junifomo e bopehileng joaloka spiral holim'a selikalikoe sa phala eohle ea tšepe, boholo ba phala ea tšepe, ho nepahala ho phahameng, matla a phahameng;
4) ho bonolo ho fetola boholo bo loketseng palo e nyenyane ea tlhahiso ea liphaephe tsa tšepe ea mefuta e mengata.

Spiral weld seam bolelele ba tube e otlolohileng, bolelele ba tube L, bolelele ba weld ke L / cos (8).Ka nako e telele ho phehisana khang ka phaephe ea seam ea spiral le e otlolohileng, haholo-holo, ke mang ea phahameng ha a bapisoa le pipe ea tšepe ea UOE.Theknoloji ea tlhahiso ea liphaephe tsa Spiral ho fihlela kajeno, re lokela ho ba le tlhahlobo e felletseng le e nepahetseng le papiso, mohopolo oa "chelete e telele ea spiral.

Pele ho tsohle, ka lebaka la liphoso tsa weld parallel, bakeng sa phala ea spiral, mefokolo ea weld e tšoana le "mefokolo ea oblique".Nakong ea ts'ebeliso, tataiso e ka sehloohong ea khatello ea phala ea tšepe, tataiso ea axis ea pipe ea bolelele bo lekanang le sekoli ke samll ho feta pipe e otlolohileng ea seam e nyenyane;Taba ea bobeli, kaha tšepe ea liphaephe ke poleiti e phuthoang, matla a anisotropy e kholo a ama tsela eo CVN e tsamaeang ka eona ho feta perpendicular ho tataiso ea boleng ba CVN ka makhetlo a mararo.Otlolohileng seam phala a utloa bohloko ke khatello ea kelello e ka sehloohong ke hantle perpendicular ho tataiso ea tlaase-tlaase phala tshusumetso ho hanyetsa, ha spiral ke ho thekesela tlaase-tlaase ka tataiso ea phala tshusumetso ho hanyetsa, e le hore spiral weld mefokolo ka melemo.
