Spiral Welded Steel Pipes Manufacturing Process
Khetho ea Lintho:
Likhoele tsa tšepe: Ho khethoa litšepe tsa boleng bo holimo, tseo hangata li entsoeng ka tšepe e nang le khabone e tlase kapa ea k'habone e mahareng, ho kopana le thepa e hlokahalang ea mochini le sebopeho sa lik'hemik'hale.
Ho phutholla le ho petsoha:
Ho phutholla: Likhoele tsa tšepe lia phuthoa ebe lia batalatsoa hore e be lakane.
Slitting: Tšepe e bataletseng e aroloa ka likhoele tsa bophara bo hlokahalang. Bophara ba lesela bo lekanya bophara ba phala ea ho qetela.
Ho theha:
Spiral Formation: Lesela la tšepe le feptjoa ka letoto la lirolara tse etsang butle-butle hore e be sebopeho sa spiral. Mathoko a mothapo a bokelloa hammoho ka mokhoa oa helical ho etsa phala.
Welding:
Submerged Arc Welding (SAW): The spiral seam ea pipe e cheselitsoe ka mokhoa oa ho tjheseletsa arc ka tlas'a metsi. Sena se kenyelletsa tšebeliso ea arc ea motlakase le granular flux, e fanang ka weld e matla, ea boleng bo phahameng e nang le spatter e fokolang.
Tlhahlobo ea Weld Seam: Seam sa weld se hlahlojoa boleng ho sebelisoa mekhoa ea tlhahlobo e sa senyeheng joalo ka tlhahlobo ea ultrasonic kapa radiographic.
Sizing le Shaping:
Sizing Mills: Peipi e cheselitsoeng e feta har'a liloala ho fihlela bophara bo nepahetseng le ho ba chitja ho hlokahalang.
Katoloso: Katoloso ea Hydraulic kapa mochini e ka sebelisoa ho netefatsa boholo ba liphaephe tse tšoanang le ho ntlafatsa thepa ea thepa.
Teko e sa Senyeheng:
Ultrasonic Testing (UT): E sebelisetsoa ho lemoha mefokolo ea ka hare ho seam weld.
Teko ea Hydrostatic: Pipe e 'ngoe le e' ngoe e tlas'a tlhahlobo ea khatello ea hydrostatic ho netefatsa hore e khona ho sebetsana le likhatello tsa ts'ebetso ntle le ho lutla.
Qetella:
Beveling: Lipheletsong tsa liphaephe li kobehile ho itokisetsa ho cheselletsa sebakeng sa ho kenya.
Kalafo ea Bokaholimo: Liphaephe li ka fumana liphekolo tse kaholimo tse kang ho hloekisa, ho roala, kapa ho kolobisoa ho matlafatsa ho hanyetsa ho bola.
Tlhahlobo le Taolo ea Boleng:
Tlhahlobo ea Dimensional: Liphaephe li hlahlojoa hore na li lumellana le bophara, botenya ba lebota, le litlhaloso tsa bolelele.
Teko ea Mechini: Liphaephe li lekoa bakeng sa matla a ho tsitsa, matla a ho hlahisa, bolelele, le ho tiea ho netefatsa hore li finyella litekanyetso tse hlokahalang.
Ho tšoaea le ho paka:
Ho tšoaea: Lipeipi li tšoailoe ka lintlha tsa bohlokoa joalo ka lebitso la moetsi, litlhaloso tsa liphaephe, kereiti, boholo le nomoro ea mocheso bakeng sa ho lateloa.
Packaging: Liphaephe li phuthetsoe ka bongata le ho phutheloa ho latela litlhoko tsa bareki, li loketse ho tsamaisoa le ho kenngoa.

Taolo ea Boleng e thata:
1) Nakong le ka mor'a tlhahiso, basebetsi ba 4 ba QC ba nang le phihlelo ea lilemo tse fetang 5 ba hlahloba lihlahisoa ka tšohanyetso.
2) Laboratori ea naha e ngolisitsoeng ka molao e nang le litifikeiti tsa CNAS
3) Tlhahlobo e amohelehang ho tsoa ho batho ba boraro ba khethiloeng/ba lefuoang ke moreki, joalo ka SGS, BV.
4) E amohetsoe ke Malaysia, Indonesia, Singapore, Philippines, Australia, Peru le UK. Re na le UL /FM, ISO9001/18001, litifikeiti tsa FPC
