Sebaka sa Tšebeliso ea Liphaephe tse Seamless Steel
1. Indasteri ea Oli le Khase
Lipeipi tsa tšepe tse sa tsitsang li bohlokoa ts'ebetsong e holimo, bohareng le tlase. Ho tloha ho li-platform tsa ho cheka ho ea ho li-refineries, liphaephe tsena li sebetsana le likhatello tse feteletseng le libaka tse senyang ka tlhokomelo e fokolang.
• E sebelisoa liphaepheng tse ka tlas'a maoatle, lipalangoang tsa oli, le methapong ea ente ea lik'hemik'hale.
• Limaraka tse kang 316L le 904L li fana ka khanyetso e phahameng ea chloride.

2. Limela tsa Lik'hemik'hale le tsa Petrochemical
Liphaephe tse se nang sekoli li tsamaisa lintho tse senyang haholo joalo ka sulfuric acid, chloride, le lik'hemik'hale tse phahameng tsa pH. Mephato e kang 304, 316L, le 310S e ratoa ka lebaka la ho se sebetse ha tsona ka lik'hemik'hale le ho hanyetsa mocheso.
• E sebelisoa ka har'a licheso, li-reactors le litšiea tsa distillation.
• Ha ho seam weld = lintlha tse fokolang tse fokolang tlas'a khatello ea maikutlo kapa kutu.
3. Phatlalatso ea Matla le Lichelete tsa Mocheso
Litsamaisong tsa mocheso o phahameng joalo ka lifeme tsa nyutlelie, thermal, le letsatsi, lipeipi tsa tšepe tse sa hloekang li sebetsa tlas'a libaesekele tse futhumatsang le mecha ea litaba e mabifi. Ho lumellana ha ASTM A213 le EN 10216-5 ho netefatsa khatello e phahameng le ho tšoarella ha mocheso.
• E loketse li-boiler tubes, li-reheater tubes, le li-condensate system.

Ke Hobane'ng ha U Re Khetha Liphaephe tsa tšepe tse se nang seamless?
Sakysteel e fana ka lethathamo le felletseng la liphaephe tsa tšepe tse se nang seamless ka limaraka le boholo bo fapaneng, kaofela li tsamaellana le litekanyetso tse kholo tsa machabeng. Ka lisebelisoa tse tsoetseng pele tsa tlhahiso le taolo e tiileng ea boleng, Sakysteel e netefatsa:
• Ho mamellana ka mokhoa o thata
• Lithako tse ikhethang tsa bokaholimo
• Ho bola ho hoholo le ho hanyetsa khatello
• Ho fana ka potlako le tlhahiso e hlophisitsoeng
Sehlahisoa se seng le se seng se hlahlojoa ka thata ho kenyelletsa tlhahlobo ea PMI, tlhahlobo ea hydrostatic, tlhahlobo ea bofokoli ba ultrasonic, le licheke tsa sebopeho.
