ERW Pipe

ERW peipi ea tšepe e cheselitsoengke peipi e otlolohileng-e entsoeng ka seam e entsoeng ka khoele ea tšepe, moo mahlakore a mela a futhumatsoang ke ho hana motlakase 'me a kopanngoa hammoho ho etsa cheseletso e tiileng ea longitudinal.ERW e emetse Electric Resistance Welded, 'me hangata e khetheloa liphaephe tsa mohala, phetisetso ea metsi, le litšebeletso tsa meralo moo OD e tsitsitseng, phano e potlakileng le taba e sebetsang hantle. The weld e matha ka longitudinally haufi le phala, ho fella ka sebopeho sa compact, matla a phahameng, le ho nepahala ha boholo bo botle. Ka katleho e phahameng ea tlhahiso le litšenyehelo tse batlang li le tlaase, liphaephe tsa ERW li fetohile khetho ea bohlokoa liindastering tse kang lipalangoang tsa oli le khase, kaho ea mehaho ea motheo, ho nosetsa temo le ho etsa mechine.

Octal Pipe e latela ka tieo litekanyetso tsa machaba ho hlahiseng liphaephe tsa ERW, ho sebelisa lisebelisoa tse ikemetseng le tse bohlale ho netefatsa ts'ebetso e tsitsitseng le e ka tšeptjoang ea sehlahisoa. Ts'ebetso e felletseng e kenyelletsa:

1. Tlhahlobo ea Raw Material & Tokiso

• Ho khethoa lipoleiti tsa tšepe tse fihlelang API, ISO, le maemo a mang a machaba.
• Motsoako oa lik'hemik'hale, thepa ea mochini, le bofokoli ba bokaholimo li lekoa ho netefatsa ho ts'oana.

2. Ho Seha & Ho Etsa

• Thepa e phahameng-ea ho seha ka nepo e netefatsa ho nepahala ha maemo.
• Lipoleiti tsa tšepe li kobeha butle-butle ka ho etsa mechine ka liphaephe tse chitja.

3. Ho Welding e Phahameng{1}Frequency Resistance Welding

• Likarolo li futhumatsoa ho fihlela boemong ba polasetiki 'me li kopantsoe hammoho le li-rollers tsa squeeze.
• Hona joale, lebelo la motlakase, le lebelo la welding li fetoloa ka bo eona ho netefatsa litšepe tse teteaneng le tse tsoelang pele.

4. Kalafo ea Mocheso (Annealing/ Normalizing)

• Ho imolla khatello ea maikutlo bakeng sa li-welds le libaka tse anngoeng ke mocheso-.
• E ntlafatsa microstructure, toughness, le crack resistance.

5. Teko le Tlhahlobo e sa Senyeheng

• Teko ea Ultrasonic (UT):e lemoha mefokolo ea ka hare ea weld.
• Teko ea hajoale ea Eddy (ECT):e khetholla mapetsong a holim'a metsi le li-inclusions.
• Teko ea Hydrostatic:e netefatsa kgatello ya kgatello.
• Tlhahlobo ea mahlakore:botenya ba lebota, ovality, mamello ea bolelele.

6. Sizing, Cutting & Finishing

• Pholiso ea spray le boholo e netefatsa ho pota-pota le ho otloloha.
• Liphaephe li khaotsoe ka bolelele ho ea ka litlhoko tsa bareki, ka chamfering le deburring.

7. Kalafo ea Bokaholimo & Coating

• Pickling, shot blasting, kapa anti{0}}anti corrosion coatings (3PE, epoxy powder) li ka thusa ho thibela kutu.
