Inkqubo yeMveliso
Inkqubo yokuvelisa i-oil casing ibandakanya izigaba ezininzi.Nantsi inkcazo jikelele yenkqubo yemveliso ye-oyile:
Ukwenziwa kwesinyithi: Isinyathelo sokuqala kukuveliswa kwentsimbi ephezulu esetyenziselwa ukuvelisa imibhobho ye-casing.Intsimbi iveliswa kumatshini wentsimbi ngeenkqubo ezifana nokunyibilika, ukucokiswa kunye nokuqiniswa.
Ukwenziwa kwemibhobho: Kweli nyathelo, intsimbi yenziwa ibe yimibhobho ngeendlela ezahlukeneyo, kubandakanywa ukwenziwa kwemibhobho engenamthungo okanye ubuchule bokuwelda ubude nobude.Imibhobho engenamthungo yenziwa ngokugqobhoza i-billet yensimbi eyomeleleyo, ngelixa imibhobho edityanisiweyo yenziwe ngokudibanisa imicu yentsimbi kusetyenziswa iindlela zokuwelda.
Ukunyangwa kobushushu: Emva kokuba imibhobho yenziwe, idlula kwinkqubo yonyango lokushisa ukunyusa iimpawu zabo zomatshini.Ukunyanga ubushushu kubandakanya ukufudumeza imibhobho kubushushu obuthile kwaye emva koko ipholise ngokukhawuleza ukuphucula amandla ayo, ukuqina, kunye nokuxhathisa ukubola.
I-Casing pipe threading: I-threading linyathelo elibalulekileyo kwimveliso ye-oyile ye-oyile.Iziphelo zemibhobho ye-casing zifakwe kwi-threaded ukwenzela ukuba ukudibanisa phakathi kwabo ngexesha lokwakhiwa kwequla.Ukudibanisa kungenziwa ngokusebenzisa iinkqubo ezahlukeneyo zokuthunga, kubandakanywa ukudibanisa kwamagxa ajikelezayo okanye ukudityaniswa kwentambo ye-tapered.
Ulawulo lomgangatho kunye nokuhlolwa: Imibhobho ye-casing iphantsi kolawulo olungqongqo kunye neenkqubo zokuhlola.Oku kubandakanya ukuhlolwa komgangatho, ukuhlolwa okubonakalayo, uvavanyo lwe-ultrasonic okanye imagnethi yokuvavanya, kunye nezinye iindlela zokuvavanya ezingonakalisi ukuqinisekisa ukuba imibhobho iyahlangabezana neenkcukacha ezifunekayo kunye nemigangatho yomgangatho.
Ukugquma nokugqiba: Imibhobho yeCasing idla ngokugqunywa ukuze ikhuseleke ekudlekeni kwaye iphucule ubomi bayo obude.Izinto zokugquma ezifana ne-epoxy, i-polyethylene, okanye i-zinc igalelwa kumphandle wemibhobho ngeendlela ezifana ne-galvanizing yediphu eshushu okanye ukufaka i-coating.Le nkqubo yokugquma inika ukuxhathisa okongeziweyo kwe-corrosion kwaye iqinisekisa ukuba imibhobho ikulungele ukuthunyelwa kwimithombo yeoli kunye negesi.
Ukupakishwa kunye nokuthumela: Emva kokuba imibhobho idlulise ulawulo lwekhwalithi kunye neenkqubo zokugubungela, zipakishwe kwaye zilungiselelwe ukuthunyelwa kubathengi.Imibhobho idla ngokudityaniswa, ibotshwe, kwaye ikhuselwe ukuthintela umonakalo ngexesha lothutho.
