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 ho sebelisoa mokhoa oa ho cheseletsa 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: Lipeipi 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.
