Coiled chubu ndi utali umodzi wa makilomita angapo ndikupindika mobwerezabwereza, kukwaniritsa mapindikidwe angapo apulasitiki a chitoliro chatsopano chamafuta. Zida zomangira machubu ndi ntchito yake zimatchedwa "makina ogwirira ntchito padziko lonse lapansi" m'maiko akunja monga United States, Canada ndi mayiko ena, zakhala zida zamafuta zophimbidwa ndi mafuta. Pakadali pano chubu lalitali kwambiri lopitilira ndi 9000m kutalika, potengera luso lapadera lopangira machubu apakatikati ndi:
1, The Chemical Elements
Chifukwa cha nkhanza chilengedwe utumiki, coiled tubing mawotchi katundu ndi kukana dzimbiri ndi zofunika kwambiri, kukhathamiritsa kamangidwe ka mankhwala zikuchokera zakuthupi, ayeneranso kukhazikitsa ulamuliro woyera ndondomeko yonse ya smelting, anagudubuza, etc., kuchepetsa inclusions ndi S, P ndi zinthu zina zoipa.
2, Processing
Popeza dislocation kuchulutsa pambuyo zifukwa zina kuumitsa ndi Bauschinger zotsatira pamodzi, kusintha lamulo tubular thupi mphamvu kulamulira.
3, Kutentha mankhwala
Ndi chubu kutentha mankhwala tikwaniritse momwe akadakwanitsira ulamuliro wa microstructure ndi katundu, makamaka mkulu mphamvu ndi ductility mkulu ndi otsika otsalira nkhawa.
4, Welding Technology
Low carbon ndi otsika aloyi zitsulo, panopa ntchito makamaka HFW kuwotcherera luso, ayenera kuphunzira momwe akadakwanitsira kuwotcherera magawo (monga panopa, voteji, pafupipafupi, liwiro kuwotcherera, kupanga ngodya, kuchuluka kukanikiza, etc.), kafukufuku ndi msoko kuwotcherera kutentha mankhwala luso.
5, mtwu
Kukwaniritsa mosalekeza kupanga HFW chitoliro, choyamba ayenera kutenga pepala yaitali, panopa pepala docking makamaka TIG, MAG ndi kuwotcherera plasma kapena zina zotero. Njira yomwe ikuphunziridwa ndi friction stir welding.
6, Chipope
Machubu ophimbidwa akamagwiritsidwa ntchito angayambitse kuwonongeka kwanuko, kuvulala kapena mbali yachilema iyenera kudulidwa, ndipo machubu amalumikizidwa ndi kuwotcherera. The chikhalidwe njira docking zombo ndi dzanja TIG kuwotcherera, ndi kuwotcherera khalidwe n'zovuta kulamulira, kuti panopa basi kuwotcherera luso.
7, matekinoloje atsopano opangira
Monga CVR luso, amene amagwiritsa ntchito chitoliro mosalekeza wa kukula chubu ndi usavutike mtima kwa 940 ℃ kudzera Intaneti sing'anga pafupipafupi kupatsidwa ulemu ndi thermomechanical anagubuduza, pa dzanja limodzi kukwaniritsa popanda msoko kapena HFW weld kukhathamiritsa, Komano kukwaniritsa variable makulidwe khoma kapena chosinthika. . Komanso, pali wapadera zosapanga dzimbiri chubu mosalekeza laser kuwotcherera luso.
