Tšepe ea Khabone e se nang Seamless Steel Tube - Sehlopha sa Borena

1. Ho phutholla ho chesang (phaephe ea tšepe e se nang sekoli e ntšang metsi): tube e chitja e se nang letho → ho futhumatsa → ho phutholla → ho phutholla ka bophara ba mararo, ho phutholla ho tsoelang pele kapa ho phutholla → ho hlobola → boholo (kapa ho fokotsa) → ho pholisa → ho otlolla → teko ea hydrostatic (kapa tlhahlobo) → ho tšoaea → polokelo
Thepa e tala ea tube e se nang seamless e chitja ke billet ea tube e chitja, embryo ea tube e chitja e sehoa le ho sebetsoa ka mochini o sehang ka kholo ea hoo e ka bang mithara e le 'ngoe e se nang letho, ebe e romeloa sebōping ka ho futhumatsa lebanta la conveyor. Billet e fepuoa ka sebōping 'me e futhumatsoa ho fihlela likhatong tse ka bang 1200 tsa Celsius. Mafura ke haedrojene kapa acetylene. Taolo ea mocheso ka sebōping ke bothata ba bohlokoa. Kamora hore billet ea tube e chitja e tsoe, e phunyeletsoa ka ho phunya ha khatello. Ka kakaretso, perforator e tloaelehileng ka ho fetisisa ke perforator ea conical roll. Mofuta ona oa perforator o na le katleho e phahameng ea tlhahiso, boleng bo botle ba sehlahisoa, bophara bo boholo ba perforating 'me o ka apara mefuta e fapaneng ea tšepe. Kamora ho phunyeletsoa, ​​billet ea tube e chitja e phuthoa ka tatellano ka makhetlo a mararo a phahameng a otlolohileng, a phethollang kapa a ntšetsoang. Kamora ho ntšetsoa ka ntle, phaephe e lokela ho tlosoa bakeng sa boholo. Caliper e potoloha ka har'a embryo ea tšepe ka drill e kobehileng ka lebelo le phahameng ho phunya masoba le ho etsa liphaephe tsa tšepe. Bophara ba ka hare ba phaephe ea tšepe bo khethoa ke bolelele ba bophara ba ka ntle ba caliper drill bit. Kamora ho lekanya phaephe ea tšepe, e kena toreng ea ho pholisa 'me e pholisoa ka ho fafatsa metsi. Kamora ho pholisa phaephe ea tšepe, e tla otlolloa.
2. Phaephe ea tšepe e se nang moedi e huloang ka serame (e phutholotsoeng): phaephe e chitja e se nang letho → ho futhumatsa → ho phunyeha → hlooho → ho annealing → ho pickling → ho tlotsa oli (ho penta koporo) → ho hula ka mokhoa o batang ka makhetlo a mangata (ho penta ka mokhoa o batang) → phaephe e se nang letho → kalafo ea mocheso → ho otlolla → teko ea hydrostatic (tlhahlobo) → ho tšoaea → polokelo.
Mokhoa oa ho phutholla oa phaephe ea tšepe e se nang moedi e batang (ho phutholla) o rarahane ho feta oa phaephe ea tšepe e se nang moedi e chesang (ho phutholla) e se nang moedi. Mehato e meraro ea pele ea ts'ebetso ea bona ea tlhahiso e tšoana hantle. Phapang ho tloha mohatong oa bone, phaephe e chitja e se nang letho ka mor'a ho phunya, ho ea hloohong, ho phutholla. Kamora ho phutholla, mokelikeli o khethehileng oa asiti o sebelisoa bakeng sa ho phutholla. Kamora ho phutholla, oli ea sebelisoa. Sena se lateloa ke kalafo e khethehileng ea mocheso ea phaephe ea rebillet kamora ho phutholla ka makhetlo a mangata a batang (ho phutholla ka serame). Kamora kalafo ea mocheso, e otlolohile.
