ʻO ka hui paipu wili he ʻāpana ia o ka paipu wili, i māhele ʻia i nā hui kāne a me nā hui wahine, i hoʻopili ʻia ma nā wēlau ʻelua o ke kino paipu wili. Hoʻolako ʻia ka mea hoʻohui me kahi kaula wili wili (kaula wili mānoanoa) e hoʻopili i kēlā me kēia paipu wili. I ke kaʻina hana wili, hoʻokaʻawale pinepine ʻia ka hui, a ua kau ʻia ka ʻili hui i kahi ikaika nahu nui, no laila ʻoi aku ka mānoanoa o ka paia o ka hui paipu wili, ʻoi aku ka nui o ke anawaena waho o ka hui ma mua o ke anawaena waho o ke kino paipu, a hoʻohana ʻia ke kila me ka ikaika kiʻekiʻe. Hana ʻia nā hui paipu wili kūloko me ke kila metala 35CrMo.
Pono e māʻona ka pilina o ke kaula wili me ʻekolu mau kūlana, ʻo ia hoʻi, ua like ka nui, ua like ke ʻano o ke kaula wili, a ua kūlike ke kaula wili kāne a me ka wahine. He ʻokoʻa nā nui o nā hui o nā paipu wili like ʻole. He ʻokoʻa nō hoʻi ke ʻano kaula o ka paipu wili o ka nui like. He paʻakikī hoʻi ke kūlike loa ke ʻano hui i hoʻohana ʻia e kēlā me kēia mea hana paipu wili. No laila, i mea e maʻalahi ai ka ʻokoʻa ma waena o nā hui paipu wili a me nā noi ʻenekinia, ua hana ʻo API i nā ʻōlelo like ma ke ʻano o nā hui paipu wili, e hana ana i nā hui paipu wili API i hoʻohana pinepine ʻia i ka ʻoihana petroleum.
Loaʻa nā mea hoʻopili paipu API i nā kūlana kahiko a me nā kūlana hou. Ua manaʻo ʻia ka hui paipu wili API kahiko no ka hoʻohana mua ʻana o ka paipu wili maikaʻi, i māhele ʻia i ʻekolu ʻano: kūloko pālahalaha (IF), perforated (FH) a me ka maʻamau (REG).
Hoʻohana nui ʻia ka hui pālahalaha o loko no ka mānoanoa o waho o ka paipu wili, kahi i hōʻike ʻia e ke anawaena o loko o ka paipu wili a me ke anawaena o loko o ka hui i ka mānoanoa o ke kino paipu, a he liʻiliʻi ke kū'ē ʻana o ke kahe wai wili, kahi e kōkua ai i ka hoʻomaikaʻi ʻana i ka mana wai o ka drill bit, akā he nui ke anawaena o waho o ka hui a maʻalahi hoʻi e komo.
He kūpono ka hui perforated no ka mānoanoa o loko o ka paipu wili, kahi i hōʻailona ʻia e ʻelua mau diamediamets o loko o ka paipu wili, a ʻo ke anawaena o loko o ka hui ua like ia me ke anawaena o loko o ka mānoanoa o ke kino paipu, akā ʻoi aku ka liʻiliʻi ma mua o ke anawaena o loko o ka ʻāpana kino paipu. ʻOi aku ka nui o ke kū'ē o ka wai wili e kahe ana ma o ka hui ma mua o ka hui pālahalaha o loko, akā ʻoi aku ka liʻiliʻi o kona anawaena o waho ma mua o ka hui pālahalaha o loko.
He kūpono ke anawaena maʻamau no ka hoʻomānoanoa ʻana o loko o ka paipu wili. He liʻiliʻi iki ke anawaena o loko o kēia hui, ʻoi aku ka liʻiliʻi ma mua o ke anawaena o loko o ka hoʻomānoanoa ʻana o ka paipu wili. No laila, aia ʻekolu mau anawaena lua like ʻole o ka paipu wili i hoʻopili ʻia me nā hui maʻamau. Ke kahe nei ka wai wili ma o kēia hui me ke kūʻē nui loa, akā ʻo ia ka liʻiliʻi loa o ke anawaena waho a me ka ikaika nui. Hoʻohana pinepine ʻia nā hui maʻamau no ka paipu wili liʻiliʻi a me ka paipu wili hoʻohuli, a me nā wili, nā mea lawaiʻa, a me nā mea ʻē aʻe. Hoʻohana nā ʻano hui ʻekolu i nā kaula ʻano "V", akā ʻokoʻa loa ke ʻano kaula wili (i hōʻike ʻia e ka laulā o ka ʻoki luna), ka mamao o ke kaula wili, ka taper a me ka nui.
Ka ʻike hui
1. puka FH, XH, ʻaʻole maʻamau i ka hale hana, ʻaʻole i hoʻohana pinepine ʻia.
2. hoʻohana pinepine ʻia ʻo IF a me ka REG maʻamau, penei ka ʻokoʻa:
Inā he 4 pihi i kēlā me kēia ʻīniha, ʻoi aku ka mānoanoa o ke kaula wili pili, a ʻoi aku ka liʻiliʻi o ke kaula taper, ʻo REG 5 pihi i kēlā me kēia ʻīniha, ʻoi aku ka liʻiliʻi o ke kaula wili pili, a ʻoi aku ka nui o ke kaula taper. ʻO ka nui o ke kaula wili IF mai 2-3/8 "a i 4-1/2", a ʻo nā mea ʻoi aku ma mua o 4-1/2 "ʻaʻohe o lākou IF, ʻo ia hoʻi ʻo REG, kahi 7-5/8" a ʻoi aku ʻaʻohe o lākou REG.
3. Ke ʻano hōʻike maʻamau:
Hōʻike ʻia ia e ʻekolu mau helu, e like me 310,410,411, a pēlā aku.
ʻO ka helu mua e hōʻike ana i ka nui (2 ~ 7) maʻamau: 2-2 -, 3-3-7/8 ", 1/2 ", 4-4-1/2 ", 5 1/2 "- 5 -, 6-6-5/8", Iulai 7-5/8 ";
Hōʻike ka helu ʻelua i ke ʻano o ke kaula wili (aia he 1, 2, 3), 1-- IF; 2---FH; 3-- REG;
ʻO ke kolu o ka helu e hōʻike ana i ke kāne a me ka wahine (i hōʻike ʻia e 0 a me 1)
0--Pahu (wahine); 1--Pin (kāne);
4. ʻO nā ʻano kaula wili paipu wili maʻamau ʻē aʻe he BTC, MT, AMT, HT55 a pēlā aku.
5. eia kekahi, ʻo ke ʻano kaula wili maʻamau o ka motika 7-5/8 "REG, 6-5/8" REG, 4-1/2 "REG, loaʻa pū kekahi 4-1/2" IF. ʻO ke ʻano kaula wili maʻamau o ka mea ʻoki paipu a me ka mea ʻoki hydraulic ʻo REG.
