API 5L Ts'ebetso ea ho Etsa Lipeipi tsa Tšepe tse Welded
Mofuta oa 1. Spiral Welded: Spiral welded lipeipi tsa tšepeli entsoe ka ho tjheseletsa lesela la tšepe ka spiral, ho etsa seam helical. Ts'ebetso ena e lumella ho hlahisa liphaephe tse kholo tsa bophara 'me hangata li na le litšenyehelo tse ngata bakeng sa likopo tse itseng.
Ho roala le ho Phekola:Ho matlafatsa ho hanyetsa kutu le ho tšoarella nako e telele, liphaephe tsena li ka 'na tsa e-ba le mekhoa e sa tšoaneng ea ho roala le ho phekola, tse kang fusion bonded epoxy (FBE) kapa polyethylene (3LPE) ea lera tse tharo.
Mofuta oa 2. Motlakase oa Resistance Welding (RW):Likarolo tsa tšepe e entsoeng ka tšepe li futhumatsoa ka ho hanyetsa motlakase. Khatello e sebelisoa ho kopanya mahlakoreng hammoho, ho theha weld e tiileng ntle le tlhoko ea thepa ea ho tlatsa.
Mofuta oa 3.Longitudinal Welding:
Submerged Arc Welding (SAW): Likarolo tsa phala e entsoeng li kopantsoe hammoho ho sebelisa mokhoa o ka tlas'a metsi oa arc welding, o kenyelletsang tšebeliso ea arc ea motlakase le phallo ea granular ho theha boleng ba boleng bo phahameng, bo matla.
Double Submerged Arc Welding (DSAW): Bakeng sa liphaephe tse teteaneng, mahlakore ka bobeli a ka hare le ka ntle a entsoe ka li-welded, ho netefatsa ho kenella ka ho feletseng le matla.
