Phapang e ka sehloohong pakeng tsa liphaephe tse peli tse cheselitsoeng tsa phala ea spiral welded le pipe e otlolohileng ke phapang ea mofuta oa welding.

Spiral welded pipe ke tšepe e tlase ea carbon carbon structural steel kapa e low alloy structural steel strip e phuthetsweng ka hara tube e se nang letho e nang le angle e itseng ya helix (eo hape e bitsoang forming angle), ebe e tjheseletsa le ho etswa lenonyeletso la phaephe, le ka sebedisang lehlaka le moqotetsane. tšepe Tlhahiso ea liphaephe tse kholo tsa tšepe tse bophara.Spiral welded pipe ke haholo-holo spiral submerged arc welded pipe (SSAW), e sebelisoang khafetsa kahong ea liphaephe tse fapaneng tsa khase Chaena.Litlhaloso tsa eona li hlahisoa ke "bophahamo ba ka ntle * botenya ba lebota".Liphaephe tse cheselitsoeng ka spiral li cheselitsoe ka lehlakore le le leng 'me li cheselitsoe ka mahlakoreng a mabeli.Pipe e cheselitsoeng e tla etsa bonnete ba hore tlhahlobo ea hydraulic le matla a tsitsitseng le ts'ebetso e batang ea ho khumama ea weld e lumellana le melaoana.

Pipe e otlolohileng e entsoeng ka seam ke sekhahla se phahameng sa maqhubu le mohato oa phello ea ho atamela o lokelang ho hlahisoa ke lera la solder pele ho tjheseletsa ho thehoa ke mochine oa ho bōpa, 'me moeli oa tube e se nang letho e futhumetse ebile e qhibiliha,' me e kopantsoe. tlasa matla a itseng a hatellang, ho bopa ho phodisang.Phaephe e otlolohileng ea seam e otlolohileng ea maqhubu a phahameng e sebelisoa moo ntlha ea phaephe e se nang letho e qhibilihisoang ke maqhubu a phahameng a maqhubu (ERW), e bitsoang seam e otlolohileng e kenang ka har'a arc weld pipe (LSAW) ka ho qhibiliha ka arc ea motlakase.

Matla a pipi e cheselitsoeng ka spiral hangata a phahame ho feta a phala e otlolohileng e cheselitsoeng.Mokhoa o ka sehloohong oa tlhahiso ke welding ea arc e ka tlas'a metsi.Pipe e entsoeng ka spiral e ka hlahisa liphaephe tse cheselitsoeng tse nang le bophara ba liphaephe tse fapaneng ka bophara bo lekanang ba likheo, hape li ka hlahisa liphaephe tse cheselitsoeng tse nang le li-diameter tse kholoanyane tse nang le likheo tse moqotetsane.

Ts'ebetso ea tlhahiso ea phala e otlolohileng ea seam e batlang e le bonolo, haholo-holo ts'ebetsong ea tlhahiso, e arotsoe ka sekhahla se phahameng sa maqhubu a marang-rang a otlolohileng seam welded phala le phala e qoelisoang ka metsing e kolobisitsoeng ka phala e otlolohileng.Pipe e otlolohileng ea seam welded e na le ts'ebetso e phahameng ea tlhahiso, theko e tlase le nts'etsopele e potlakileng.

Leha ho le joalo, ha ho bapisoa le phala e otlolohileng e cheselitsoeng phala ea bolelele bo lekanang, bolelele ba weld bo eketseha ka 30 ho isa ho 100, 'me lebelo la tlhahiso le tlaase.Ka hona, liphaephe tse nyenyane tse cheselitsoeng ka bophara ke boholo bo otlolohileng seam, ha bophara bo boholo ba liphaephe tse cheselitsoeng hangata li tsoetsoe ka spiral.
