Ts'ebetso ea tlhahiso ea lipeipi tsa tšepe tse se nang leoatle haholo e kenyelletsa mehato ea bohlokoa e latelang:

1. Taolo ea Billert
Lisebelisoa tse tala tsa lipeipi tsa tšepe tse se nang leoatle ke tšepe e chitja kapa linoko hangata tšepe ea nama ea mofuta oa khase kapa tšepe e tlase. Koti e hloekisoa, bokaholimo ba eona bo hlahlojoa bakeng sa likoli, 'me ho khaola bolelele bo hlokahalang.

2. Ho futhumatsa
Billellet e romeloa moqomong o futhumatsang oa ho futhumatsa, hangata ho futhumatsa mocheso oa ka bang 1200 ℃. Heating e apehileng e tlameha ho netefatsoa nakong ea ho futhumatsa e le hore ts'ebetso e tlang pele e ka tsoela pele hantle.

3. PUSELETSO
Billet e futhumetseng e pentiloe ke seporo se litšila ho theha tube e thata. Mokhoa o tloaelehileng o sebelisoang ke "oblique o" oblique "e sebelisang li-roller tse ling tse bulang ho sutumelletsa pele, e le hore setsi ha se letho.

4. Rolla (ho otlolla)
Phala e nang le pherekano e mpe e otlolohile ebile e entsoe ka lisebelisoa tse fapaneng tsa ho potoloha. Hangata ho na le mekhoa e 'meli:

Mokhoa o tsoelang pele o roll o tsoelang pele: Sebelisa sehlopha se fetang sa ho rohakana ho fetisa ha ho sotha butle butle ho fokotsa phala e mpe ebe e fokotsa botenya.

Mokhoa oa ho jala oa pampiri: Sebelisa mandrel ho thusa ho otlolla le ho phalla ho laola makhasi a kahare le a kantle a pompo ea tšepe.

5. Ho ithiba le ho fokotsa
Bakeng sa ho fihlella boholo bo nepahetseng bo loketseng, phala e mpe e sebetsoa ka leloala le leloala le leloala le leloala la ho fokotsa. Ka ho putlama ho tsoelang pele le ho otlolla, bophara ba kantle le mabala a mabala a phapoli a fetotsoe.

6. Phekolo ea mocheso
Bakeng sa ho ntlafatsa thepa ea mochini oa mochini oa tšepe le ho tlosa khatello ea maikutlo, hangata ts'ebetso ea tlhahiso e kenyelletsa ho akheha, ho futhumatsa kapa ho tima. Mohato ona o ka ntlafatsa ho ba thata le ho tšoarella ha phala ea tšepe.

7. E otloloha le ho khaola
PIPE ea tšepe kamora kalafo ea mocheso e kanna ea inama 'me e hloka ho otloloha ke mohlaka. Kamora ho otlolla, phala ea tšepe e khaoloa bolelele bo hlokoang ke moreki.

8. Tlhahlobo
Li-pipi libope tsa tšepe tsa tšepe li hloka ho hlahisa litlhahlobo tsa boleng bo holimo, tse tloaetseng hangata ho latelang:

Tlhahlobo ea ponahalo: Lekola hore na ho na le mapetso, likokoanyana, joalo-joalo ho polasetiki ea tšepe.
Tlhahlobo ea Bokhabiso: Lekanya Hore na bophara ba bophara, matloana a lebota le bolelele ba pompo ea tšepe li khotsofatsa litlhokahalo.
Tlhahlobo ea thepa ea tikoloho: joalo ka tlhahlobo ea teko, tlhahlobo ea tšusumetso, tlhahlobo ea mathata, jj.
Teko e sa senyeheng: Sebelisa Ultrasound kapa X-ray ho bona hore na ho na le mapetso kapa lipere kahare.
9. Ho paka le ho fana
After passing the inspection, the steel pipe is treated with anti-corrosion and anti-rust treatment as required, and packed and shipped.

Ka mehato e kaholimo, lipeipi tse se nang leoatle li hlahisoa haholo li sebelisoa haholo ka oli, khase ea tlhaho, makoloi, anterospace le masimong a bona a phahameng le thepa e ntle.
