Ha e bapisoa le tšepe e tiileng, boima ba eona bo bobebe ha ho kobeha le matla a torsion a tšoana. Tšepe e nang le likarolo tse fapaneng tsa moruo e sebelisoang haholo ha ho etsoa likarolo tsa meralo le tsa mochini, joalo ka lithupa tsa koloi, lipeipi tsa ho phunya oli, liforeimi tsa libaesekele le scaffolding ea tšepe e sebelisoang kahong.

2. Pipe ea tšepe e cheselitsoeng ke phala ea tšepe e entsoeng ka lipoleiti tsa tšepe tsa welding kapa marapo a tšepe ka mor'a ho kobeha le ho thehoa. Ts'ebetso ea tlhahiso ea liphaephe tsa tšepe tse cheselitsoeng e bonolo, e nang le mefuta e mengata le litlhaloso, lichelete tse fokolang tsa lisebelisoa, le katleho e phahameng ea tlhahiso, empa matla a eona a kakaretso a tlase ho feta a liphaephe tsa tšepe tse se nang moeli. Ka nts'etsopele e potlakileng ea tlhahiso e tsoelang pele ea ho roala tšepe ea boleng bo holimo le tsoelo-pele ea theknoloji ea ho cheselletsa le ho hlahloba, boleng ba li-welds bo ntse bo ntlafala, mefuta le litlhaloso tsa liphaephe tsa tšepe tse cheselitsoeng li ntse li eketseha letsatsi le letsatsi, 'me li nkile sebaka sa seamless. lipeipi tsa tšepe masimong a mangata le ho feta. Lipeipi tsa tšepe tse cheselitsoeng li arotsoe ka liphaephe tsa tšepe tse entsoeng ka spiral le liphaephe tse otlolohileng tsa seam tse entsoeng ka tšepe ho latela sebōpeho sa weld. .

Ts'ebetso ea tlhahiso ea phala e otlolohileng ea seam welded tšepe e bonolo, e theko e tlase, nts'etsopele e potlakileng, le katleho e phahameng ea tlhahiso. Matla a lipeipi tsa tšepe tse cheselitsoeng ka spiral hangata a phahame ho feta a lipeipi tsa tšepe tse otlolohileng tsa seam. Liphaephe tsa tšepe tse cheselitsoeng tse nang le li-diameter tse kholoanyane li ka hlahisoa ho tloha ho li-billet tse fokolang, 'me liphaephe tsa tšepe tse cheselitsoeng tse nang le li-diameter tse fapaneng li ka boela tsa hlahisoa ho tloha likoloto tsa bophara bo lekanang. Leha ho le joalo, ha ho bapisoa le liphaephe tsa tšepe tse otlolohileng tsa bolelele bo lekanang, bolelele ba weld bo eketseha ka 30 ~ 100%, 'me lebelo la tlhahiso le tlaase. Ka hona, liphaephe tse nyane tse cheselitsoeng ka tšepe hangata li sebelisa welding e otlolohileng ea seam, ha liphaephe tse kholo tsa tšepe tse cheselitsoeng hangata li sebelisa spiral welding.
