Mea hoʻolako i nā ʻāpana pihi IADC637 7 7/8 ” (200mm)
Hōʻike huahana
Kūʻai nui ʻo API TCI tricone drill bits me ke kumu kūʻai hoʻemi i ke kumukūʻai mai Kina ka mea hoʻolako no ka wili luawai
Wahi wehewehe:
IADC: 637 - ʻO ka puke pai TCI i hoʻopaʻa ʻia i ka bit bearing bit me ka pale ana no nā hana paʻakikī waena me ka ikaika compressive kiʻekiʻe.
Ka ikaika compressive:
100 - 150 MPA
14,500 - 23,000 PSI
Ka wehewehe ʻāina:
ʻO nā pōhaku paʻakikī a paʻa maikaʻi e like me: nā limestone silica paʻakikī, nā streaks quarzite, pyrite ores, hematite ores, magnetite ores, chromium ores, phosphorite ores a me granite.
Hiki iā mākou ke hāʻawi i nā ʻāpana TCI i nā ʻano nui (mai 3 3/8" a i 26") a me ka hapa nui o nā code IADC.
ʻO nā ʻano hoʻonohonoho hydraulic like ʻole e hōʻoia i ka hoʻomaʻemaʻe pono ʻana o ka bit a me ka hole i nā noi he nui. Hiki i nā nozzles ke hoʻomaʻemaʻe i ka kuʻekuʻe wāwae a me nā niho kuʻekuʻe pili..
ʻOi aku ka liʻiliʻi o nā ʻāpana o kēlā me kēia ʻāpana, liʻiliʻi nā huakaʻi i waho o ka lua, a me nā lā liʻiliʻi e hoʻopau ai i kāu pūnāwai e hoʻemi i kāu kumukūʻai-per-foot.

ʻO Far Eastern ka hale hana kūikawā i nā bits drill, e like me nā tricone bits, PDCs bits, HDD hole opener, Foundation roller cutters no nā noi like ʻole. HDD, Kūkulu a me ke kahua...
Ma ke ʻano he hale hana drill bits ma Kina, e hoʻonui i ke ola hana drill bit kā mākou pahuhopu. Ke ho'āʻo mau nei mākou e hoʻomaikaʻi i nā bits me nā helu komo kiʻekiʻe. ʻO kā mākou misionari e hoʻohaʻahaʻa i ke kumukūʻai o ka drilling-per-meter. .ʻO kā mākou kumu e kūʻai aku i ke kūlana kiʻekiʻe me ke kumu kūʻai haʻahaʻa.
