I-drill pipe joint iyisakhi sepayipi lokubhoboza, elihlukaniswe ngamajoyinti abesilisa nabesifazane, axhunywe kuzo zombili iziphetho zomzimba wepayipi lokubhoboza. Isixhumi sinikezwa intambo yesikulufu sentambo (intambo yesikulufu esijiyile) ukuxhuma ipayipi ngalinye lokubhoboza. Enqubweni yokubhoboza, ijoyinti livame ukuhlukaniswa, futhi ubuso obuhlangene bubhekene namandla amakhulu okuluma, ngakho-ke ubukhulu bodonga lwejoyinti lepayipi lokubhoboza bukhulu, ububanzi bangaphandle obuhlangene bukhulu kunobubanzi bangaphandle bomzimba wepayipi, futhi kusetshenziswa insimbi ye-alloy enamandla aphezulu. Amajoyinti epayipi lokubhoboza asekhaya ngokuvamile enziwe ngensimbi ye-alloy engu-35CrMo.
Ukuxhumeka kwentambo yesikulufu kumele kwaneliswe yizimo ezintathu, okungukuthi, usayizi uyalingana, uhlobo lwentambo yesikulufu luyafana, kanti intambo yesikulufu yesilisa neyesifazane iyahambisana. Ubukhulu obuhlangene bepayipi yokubhoboza ehlukene buhlukile. Uhlobo lwentambo yepayipi yokubhoboza enobukhulu obufanayo nayo ihlukile. Uhlobo oluhlangene olusetshenziswa umenzi wepayipi yokubhoboza ngamunye kunzima ukuluqonda ngokuphelele. Ngakho-ke, ukuze kube lula ukuhlukanisa phakathi kwamajoyinti epayipi yokubhoboza kanye nezicelo zobunjiniyela, i-API yenze amalungiselelo afanayo ngohlobo lwamajoyinti epayipi yokubhoboza, yakha amajoyinti epayipi yokubhoboza e-API avame ukusetshenziswa embonini kaphethiloli.
Ukufakwa kwamapayipi e-API kuyatholakala kokubili ngezindinganiso ezindala nezintsha. I-API drill pipe joint endala ihlongozwa ukusetshenziswa kwasekuqaleni kwepayipi elincane lokubhoboza, elihlukaniswe ngezinhlobo ezintathu: i-internal flat (IF), i-perforated (FH) kanye ne-regular (REG).
I-inner flat joint isetshenziswa kakhulu ekuqineni kwangaphandle kwepayipi lokubhoboza, elibonakala ngobubanzi bangaphakathi bepayipi lokubhoboza kanye nobubanzi bangaphakathi be-joint ekuqineni komzimba wepayipi, futhi ukumelana nokugeleza koketshezi lokubhoboza kuncane, okusiza ekuthuthukiseni amandla amanzi e-drill bit, kodwa ububanzi bangaphandle be-joint bukhulu futhi kulula ukubugqoka.
Ijoyinti elimboziwe lifanelekela ukuqina kwangaphakathi kwepayipi lokubhoboza, elibonakala ngama-diamediamet amabili angaphakathi epayipi lokubhoboza, kanti ububanzi bangaphakathi bejoyinti bulingana nobubanzi bangaphakathi bokuqina komzimba wepayipi, kodwa bungaphansi kobubanzi bangaphakathi bengxenye yomzimba wepayipi. Ukumelana koketshezi lokubhoboza olugeleza ejoyintini kukhulu kunokwejoyinti elingaphakathi eliyisicaba, kodwa ububanzi balo bangaphandle buncane kunobejoyinti elingaphakathi eliyisicaba.
Ijoyinti elijwayelekile lifanelekela ukuqina kwangaphakathi kwepayipi lokubhoboza. Ububanzi bangaphakathi baleli joyinti buncane kakhulu, bungaphansi kobubanzi bangaphakathi bokuqina kwepayipi lokubhoboza. Ngakho-ke, kunezinhlobo ezintathu ezahlukene zama-bore diameters zepayipi lokubhoboza ezixhunywe namajoyinti avamile. Uketshezi lokubhoboza lugeleza kuleli joyinti ngokumelana okukhulu kakhulu, kodwa lunobubanzi obuncane bangaphandle namandla amakhulu. Amajoyinti avamile avame ukusetshenziselwa ipayipi lokubhoboza elincane kanye nepayipi lokubhoboza elibuyela emuva, kanye nama-drill, amathuluzi okudoba, njll. Izinhlobo ezintathu zamajoyinti zonke zisebenzisa imicu yomumo we-"V", kodwa uhlobo lwentambo yesikulufu (oluvezwa ububanzi bokusika okuphezulu), ibanga lentambo yesikulufu, i-taper kanye nosayizi kuhlukile kakhulu.
Ukuhlonza amalunga
1.imbobo FH, XH, ayivamile esitolo samathuluzi, ayisetshenziswa njalo.
2. I-IF evame ukusetshenziswa kanye ne-REG evamile, umehluko ungokulandelayo:
UMA izinkinobho ezingu-4 nge-intshi, intambo yesikulufu ehlobene ikhuluphele, kanti i-taper incane, izinkinobho ezingu-REG ezingu-5 nge-intshi, intambo yesikulufu ehlobene incane, kanti i-taper inkulu. Usayizi wentambo yesikulufu se-IF usukela ku-2-3/8 "kuya ku-4-1/2", kanti lezo ezingaphezu kuka-4-1/2 "azinawo ama-IF, ngokuvamile ama-REG, lapho u-7-5/8" nangaphezulu engenawo ama-REG.
3. Indlela evamile yokuveza:
Imelelwa izinombolo ezintathu, njengo-310,410,411, njll.
Inombolo yokuqala ikhombisa usayizi (2 ~ 7) ngokuvamile: 2-2 -, 3-3-7/8 ", 1/2 ", 4-4-1/2 ", 5 1/2 "- 5 -, 6-6-5/8", Julayi 7-5/8 ";
Inombolo yesibili ikhombisa uhlobo lwentambo yesikulufu (kukhona u-1, 2, 3), 1-- IF; 2--FH; 3-- REG;
Inombolo yesithathu imele owesilisa nowesifazane (emelelwe u-0 no-1)
0--Ibhokisi (lowesifazane); 1--Iphini (lowesilisa);
4. Ezinye izinhlobo zentambo yesikulufu sepayipi lokubhoboza ezivamile yi-BTC, MT, AMT, HT55 njalo njalo.
5. Ngaphezu kwalokho, uhlobo oluvamile lwentambo yesikulufu senjini engu-7-5/8 "REG, 6-5/8" REG, 4-1/2 "REG, nayo ine-4-1/2" IF. Uhlobo oluvamile lwentambo yesikulufu yesikrufu sepayipi kanye nesikhiphi se-hydraulic yi-REG.
