Liphaephe tsa tšepe li tla ka mefuta e mengata le boholo. Pipe e se nang seam ke khetho e se nang welded, e entsoeng ka billet ea tšepe e sekoti. Ha ho tluoa tabeng ea liphaephe tsa tšepe tse cheselitsoeng, ho na le likhetho tse tharo: ERW, LSAW le SSAW.
Liphaephe tsa ERW li entsoe ka lipoleiti tsa tšepe tse cheselitsoeng. Pipe ea LSAW e entsoe ka poleiti ea tšepe e kentsoeng ka metsing ka longitudinal. Pipe ea SSAW e entsoe ka spiral submerged arc welded steel plate.
A re ke re hlahlobisiseng mofuta o mong le o mong oa phala, bapisa liphapang tsa bona, le mokhoa oa ho sebelisa tlhaloso e nepahetseng ho odara.
Seamless tšepe tube
Thepa e se nang moroko e entsoe ka billet ea tšepe e sa hloekang, e futhumatsang le ho phunyeletsoa ho etsa karolo e chitja e sekoti. Hobane phala e se nang moeli ha e na sebaka sa ho cheselletsa, e nkoa e le matla ho feta peipi e cheselitsoeng 'me ha e na tšekamelo ea ho bola, khoholeho ea mobu le ho hlōleha ka kakaretso.
Leha ho le joalo, litšenyehelo ka tone e le 'ngoe ea phala e se nang seam e phahame ka 25-40% ho feta ea pipe ea ERW. Bophahamo ba lipeipi tsa tšepe tse sa tsitsang bo tloha ho 1/8 inch ho isa ho 36 inch.
Resistance welding (RW) pipe
ERW (resistance welding) pipe ea tšepe e thehoa ka ho roala tšepe ka phala le ho kopanya lipheletsong tse peli ka li-electrode tse peli tsa koporo. Li-electrode tsena li bōpehile ka disc 'me li potoloha ha thepa e feta pakeng tsa tsona. Sena se lumella electrode ho boloka ho kopana ho tsoelang pele le thepa ka nako e telele ea tjheseletsa e tsoelang pele. Khatelo-pele ea theknoloji ea welding e ntse e tsoela pele ho ntlafatsa mokhoa ona.
Pipe ea ERW e nka sebaka sa chelete e ngata ebile e sebetsa hantle bakeng sa phala ea tšepe e se nang seam, e tšoarellang ho feta peipi ea SAW. Ha ho bapisoa le ts'ebetso ea solvent e sebelisoang ka pipe e entsoeng ka tlas'a metsi arc welded, mefokolo le eona ha e na monyetla oa ho etsahala, 'me mefokolo e otlolohileng ea weld e ka fumanoa habonolo ka ultrasonic reflection kapa pono.
Bophara ba phaephe ea ERW bo tloha ho lisenthimithara tse 15 ho isa ho tse 24 (21.34 mm).
Peipi e kolobisitsoeng ea arc e kentsoeng ka metsing
LSAW (welding e otlolohileng ea seam) le SSAW (spiral seam welding) ke mefuta e fapaneng ea liphaephe tse kentsoeng ka tlas'a metsi. Ts'ebetso ea welding ea arc e ka tlas'a metsi e hlahisa boima bo phahameng ba hona joale ho thibela ho senyeha ha mocheso o potlakileng oa lera la flux le ho tsepamisa mohopolo sebakeng sa ho tjheseletsa.
Phapang e kholo lipakeng tsa liphaephe tsa LSAW le SSAW ke tataiso ea weld, e tla ama matla a ho jara khatello le boiketlo ba tlhahiso. LSAW e sebelisoa bakeng sa lits'ebetso tsa motlakase oa mahareng ho isa ho matla a phahameng, 'me SSAW e sebelisetsoa lits'ebetso tsa motlakase o tlase. Liphaephe tsa LSAW li theko e boima ho feta lipeipi tsa SSAW.
Longitudinal submerged arc welded pipe
Pipe ea LSAW e entsoe ka ho etsa hlobo e chesang e kolobisitsoeng ea tšepe hore e be silindara le ho kopanya lipheletsong tse peli hammoho ka tjheseletsa e melang. Sena se etsa phala e cheselitsoeng ka longitudinally. Liphaephe tsena li sebelisoa haholo-holo bakeng sa lipeipi tsa phetiso ea libaka tse telele tsa oli, khase ea tlhaho, mashala a metsi, li-hydrocarbon, jj.
Ho na le mefuta e 'meli ea liphaephe tsa LSAW: seam se le seng sa longitudinal le seam habeli (DSAW). Pipe ea tšepe ea LSAW e qothisana lehlokoa le peipi ea tšepe e se nang seam le phala ea tšepe ea ERW ea 16 ho isa ho 24 inch. Ka indasteri ea oli le khase ea tlhaho, liphaephe tse kholo tsa API 5L LSAW li sebelisoa bakeng sa ho tsamaisa li-hydrocarbon tse telele le tse sebetsang hantle.
Bophara ba phala ea MOLAO hangata bo pakeng tsa lisenthimithara tse 16 le 60 (406 mm le 1500 mm).

Pipe ea SSAW
Pipe ea tšepe ea SSAW e entsoe ka ho roala le ho tjheseletsa mohala oa tšepe ka tsela e spiral kapa ea spiral ho etsa hore weld e be spiral. Ts'ebetso ea spiral welding e etsa hore ho khonehe ho etsa lihlahisoa tsa bophara bo boholo. Liphaephe tsa tšepe tsa Spiral li sebelisoa haholo bakeng sa phetisetso ea mokelikeli o tlase oa khatello, joalo ka liphaephe tse sethaleng sa maoatle, limela tsa petrochemical kapa libaka tsa likepe, hammoho le meaho ea sechaba le liqubu.
Bophahamo ba liphaephe tsa SSAW ka kakaretso ke lisenthimithara tse 20 ho isa ho tse 100 (406 mm ho isa ho 25040 mm).
Mokhoa oa ho odara liphaephe tsa tšepe bakeng sa morero oa hau
Ha o laela liphaephe tsa tšepe, ho na le litekanyo tse peli tsa bohlokoa: boholo ba pipe ea lebitso (NPS) le botenya ba marako (kemiso). Bakeng sa liphaephe tse ka tlase ho lisenthimithara tse 4, bolelele ba liphaephe e ka ba e le 'ngoe feela (SRL) 5-7 limithara, kapa bakeng sa liphaephe tse fetang lisenthimithara tse 4, bolelele ba liphaephe bo ka ba habeli ka tšohanyetso (DRL) 11-13 limithara. Bolelele ba tloaelo bo fumaneha bakeng sa liphaephe tse telele. Lipheletso tsa liphaephe e ka ba bevel (be), sefofane (pe), khoele (THD) khoele le coupling (T&C) kapa groove.
