Tekanyetso ea API 5L ea seamless tšepe peipi ke tlhaloso e ntlafalitsoeng ke American Petroleum Institute (API) mme e sebelisoa haholo lits'ebetsong tsa lipeipi indastering ea oli le khase. API 5L lipeipi tsa tšepe tse se nang moroalo li sebelisoa haholo ho tsamaiseng oli, khase ea tlhaho, metsi le lino tse ling ka lebaka la matla a tsona a matla le ho hanyetsa kutu. Se latelang ke selelekela sa lisebelisoa tse fapaneng tsa API 5L standard le mofuta oa ts'ebeliso ea tsona, ts'ebetso ea tlhahiso le tlhahlobo ea feme.

Lintho tse bonahalang
API 5L Gr.B, API 5L Gr.B X42, API 5L Gr.B X52, API 5L Gr.B X60, API 5L Gr.B X65, API 5L Gr.B X70

Mokhoa oa tlhahiso
Ts'ebetso ea tlhahiso ea API 5L phala ea tšepe e se nang seamless e kenyelletsa mehato e latelang:

Khetho ea thepa e tala: Khetha litšepe tsa boleng bo holimo, hangata tšepe ea khabone kapa tšepe ea alloy e tlase.
Ho futhumala le ho phunya: Billet e futhumatsoa ho mocheso o loketseng ebe ho etsoa sekoti sa tube billet ka mochine o phunyang.
Hot rolling: The hollow tube billet e ntse e sebetsoa hape holim'a leloala le chesang ho etsa bophara bo hlokahalang ba phala le botenya ba lebota.
Phekolo ea mocheso: Ho tloaeleha kapa ho tima le ho futhumatsa phala ea tšepe ho ntlafatsa thepa ea eona ea mochini.
Setšoantšo se batang kapa ho roala ho batang: Ho taka ho batang kapa ho thetheha ho batang ho etsoa kamoo ho hlokahalang ho fihlela boleng bo holimo le boleng bo holimo.
Tlhahlobo ea feme
API 5L lipeipi tsa tšepe tse se nang moroalo li tlameha ho hlahlojoa ka thata pele li tloha fekthering ho netefatsa hore li fihlela litlhoko tse tloaelehileng:

Tlhahlobo ea metsoako ea lik'hemik'hale: Lemoha motsoako oa lik'hemik'hale oa pipe ea tšepe ho netefatsa hore e finyella litekanyetso tse boletsoeng.
Teko ea thepa ea mochini: Ho kenyeletsoa matla a ho tiea, matla a tlhahiso le liteko tsa bolelele.
Teko e sa senyeheng: Sebelisa tlhahlobo ea bofokoli ba ultrasonic le tlhahlobo ea X-ray ho lekola mefokolo ea kahare ea phala ea tšepe.
Ho lemoha ha tekanyo: Etsa bonnete ba hore bophara ba ka ntle, botenya ba lebota le bolelele ba phala ea tšepe li finyella litlhoko.
Teko ea Hydrostatic: Etsa tlhahlobo ea hydrostatic pipeng ea tšepe ho netefatsa polokeho ea eona le ho tšepahala tlas'a khatello ea ho sebetsa.
Kakaretso
API 5L lipeipi tsa tšepe tse se nang seam li sebelisoa haholo tšimong ea lipalangoang tsa oli le khase ka lebaka la matla a tsona a phahameng, ho hanyetsa kutu le thepa e ntle ea mochini. Liphaephe tsa tšepe tsa API 5L tsa lihlopha tse fapaneng tsa thepa li loketse likhatello tse fapaneng le maemo a tikoloho, ho finyella litlhoko tsa maemo a sa tšoaneng a sebetsang a rarahaneng. Mekhoa e tiileng ea tlhahiso le tlhahlobo ea fektheri e netefatsa boleng le ts'ebetso ea liphaephe tsa tšepe, ho fana ka tiiso bakeng sa tsamaiso e sireletsehileng le e sebetsang ea lipalangoang.
