Coiled tubing ke bolelele bo le bong ba lik'hilomithara tse 'maloa le ho kobeha khafetsa, ho fihlela polasetiki e ngata ea peipi e ncha ea oli. Thepa e kopantsoeng ea li-tubing le ts'ebetso ea eona e bitsoa "mochini o sebetsang oa bokahohleng" linaheng tse ling tse kang United States, Canada le linaheng tse ling, e se e le sebaka sa oli se kopantsoeng sa lisebelisoa tsa oli tsa bohlokoa. Hajoale, tubing e telele ka ho fetesisa e bolelele ba 9000m, mabapi le theknoloji e joalo ea mantlha ea mantlha ea ho etsa li-tubing ke:
1, Lintho tsa lik'hemik'hale
Ka lebaka la ts'ebeletso e thata ea tikoloho, thepa ea mochini oa li-tubing tse kopantsoeng le ho hanyetsa kutu li na le litlhoko tse phahameng, ho ntlafatsa moralo oa sebopeho sa lik'hemik'hale tsa thepa, e tlameha hape ho kenya ts'ebetsong taolo e hloekileng ea ts'ebetso eohle ea ho qhibiliha, ho roala, joalo-joalo, ho fokotsa li-inclusions. le S, P le likarolo tse ling tse kotsi.
2, Ho sebetsa
Kaha dislocation atisa ka mor'a lisosa tse ling ho thatafatsa le phello Bauschinger hammoho, fetola molao tubular matla a 'mele ho laola.
3, Phekolo ea mocheso
Ka tube mocheso kalafo ho finyella optimum taolo ya microstructure le thepa, haholo-holo matla a phahameng le ductility phahameng le khatello e tlaase mesaletsa.
4, Theknoloji ea Welding
Khabone e tlase le tšepe e tlase ea alloy, e sebelisoang haholo-holo theknoloji ea HFW welding, e hloka ho ithuta litekanyo tse nepahetseng tsa tjheseletsa (joalo ka hona joale, voltage, frequency, lebelo la ho tjheseletsa, lebelo la ho etsa angle, palo e hatellang, joalo-joalo), lipatlisiso le kalafo ea mocheso oa seam weld. thekenoloji.
5, butle
Ho finyella tlhahiso e tsoelang pele ea HFW pipe, e tlameha ho qala pele ho nka letlapa le lelelele, lakane ea hona joale ea docking haholo-holo TIG, MAG le plasma welding kapa tse ling tse joalo. Mokhoa o ntseng o ithutoa ke mokhoa oa ho cheselletsa friction stir.
6, Boto ea phala
Li-tubing tse kopantsoeng nakong ea ts'ebeliso li ka baka tšenyo ea lehae, kotsi kapa karolo e nang le sekoli e tlameha ho khaoloa, 'me li-tubes li hokahane ka tjheseletsa. Mokhoa oa setso oa likepe tsa likepe ka letsoho TIG tjheseletsa, boleng tjheseletsa ke ho le thata ho laola, e le hore hona joale jarolla ka ho iketsa thekenoloji tjheseletsa.
7, theknoloji e ncha ea tlhahiso
Joalo ka thekenoloji ea CVR, e sebelisang phala e tsoelang pele ea tube ea boholo bo lekanang 'me e futhumetse ho 940 ℃ ka ho kenngoa ha maqhubu a marang-rang ka thermomechanical rolling, ka lehlakoreng le leng ho finyella ts'ebetso ea seamless kapa HFW weld optimization, ka lehlakoreng le leng ho finyella botenya bo feto-fetohang kapa bo ka fetoloang. . Ho feta moo, ho na le theknoloji e khethehileng ea tšepe e sa hloekang ea tube continuous laser welding.
