b) Ho phunya

• Billet e futhumetseng e fetisoa ka leloala le phunyang ho etsa setsi se sekoti.

• Sesepa se potolohang le lirolara li sebelisoa ho theha sebopeho sa li-tubula tsa mantlha.

c) Ho lelefatsa

• Billet e phunyeletsoeng (hona joale e se e le tube e sekoti) e fetisoa ka liloala tse telele tse kang mandrel mill kapa plug Mills.

• Maloala ana a otlolla tube le ho ntlafatsa botenya ba lebota le bophara.

d) Ho Rolling ho chesang

• Thepa e boetse e bōpehile ka boholo le boholo ka liloala tse chesang.

• Sena se tiisa ho ts'oana le ho nepahala ha mahlakore.

e) Ho pholisa le ho otlolla

• Pipe e pholile holim'a conveyor kapa moeeng.

• Joale e otlolloa ebe e khaola ka bolelele bo lakatsehang.

f) Tlhahlobo le Teko

• Liphaephe li etsa liteko tse fapaneng tse sa senyeheng le tse senyang (mohlala, ultrasonic, hydrostatic).

• Ho tšoaea le ho paka ho etsoa ho latela maemo a indasteri.

sakysteele fana ka liphaephe tse kolobisitsoeng tse se nang moroallo ka limaraka le boholo bo fapaneng, tse lekiloeng ka botlalo le tse netefalitsoeng bakeng sa netefatso ea boleng.

3. Likarolo tsa Bohlokoa tsa Pipe e Chesang e Seamless

• Sebopeho se se nang Metsi: Ha ho seam e cheselitsoeng ho bolela ho hanyetsa khatello e ntle le ho tšepahala ha sebopeho.

• Ho hanyetsa Mocheso o Phahameng: E ka mamella mocheso o phahameng ntle le deformation kapa ho hloleha.

• Mamello ea Khatello: Ts'ebetso e babatsehang tlas'a khatello e phahameng ea ka hare kapa ea ka ntle.

• Botenya ba Lebota bo sa Tšoaneng: Ho roala ho chesang ho tiisa taolo e ntle ea botenya.

• Sebaka se Ntle se Felletseng: Leha e se boreleli joalo ka lipeipi tse huloang ke serame, lipeipi tse kolobisitsoeng tse chesang li na le pheletso e amohelehang bakeng sa tšebeliso ea indasteri.

4. Lisebelisoa le Maemo

Liphaephe tse se nang seamless tse chesang li fumaneha ka lisebelisoa tse fapaneng ho latela ts'ebeliso:

Lisebelisoa tse Tloaelehileng:

• Carbon steel (ASTM A106, ASTM A53)

• Alloy steel (ASTM A335)

• Tšepe e sa hloekang (ASTM A312)

• Tšepe ea mocheso o tlase (ASTM A333)

Maemo a Tloaelehileng:

• ASTM

• EN/DIN

• API 5L / API 5CT

• JIS

sakysteele fana ka boikamahanyo bo felletseng le litlhaloso tsa matjhaba ho fihlela ditlhoko tsa mebaraka ya lefatshe.

5. Likopo tsa Pipe e chesang e kentsoeng e se nang seamless

Liphaephe tse chesang tse kentsoeng ka seamless li sebelisoa likarolong tse ngata ka lebaka la ts'epo le ts'ebetso ea tsona.

a) Indasteri ea Oli le Khase

• Ho tsamaisa oli e tala le khase ea tlhaho

• Li-tubing tsa Downhole le casing

• Liphaephe tsa ho hloekisa

b) Pheliso ea Matla

• Li-tubes tsa boiler

• Li-tubes tse futhumatsang mocheso

• Lisebelisoa tsa Superheater

c) Boenjiniere ba Mechini

• Likarolo tsa mochini le likarolo
