Kei roto i te whare hanga API o te TCI tricone biit IADC637 6 “(152.4mm)
Whakaahuatanga Hua
Ngā mata keri kōne roera API TCI tricone rarawe me te utu whakaheke i roto i te taonga mai i te wheketere Haina mō te keri puna
Whakaahuatanga Moka:
IADC: 637 - Mata pere hiri TCI me te tiaki ine mō ngā hanganga pakeke waenga me te kaha pēhi teitei.
Kaha Whakapūmau:
100 - 150 MPA
14,500 - 23,000 PSI
Whakaahuatanga Whenua:
Ngā toka mārō, kua pai te whakapiripiri, pērā i: ngā kōhatu kōhatu mārō, ngā rārangi quarzite, ngā konganuku pyrite, ngā konganuku hematite, ngā konganuku magnetite, ngā konganuku chromium, ngā konganuku phosphorite me ngā granite.
Ka taea e mātou te tuku atu i ngā momo rahi o ngā moka TCI (mai i te 3 3/8" ki te 26") me te nuinga o ngā waehere IADC.
He momo peera hiri rapa me te peera mata whakarewa te momo mata tricone IADC637. He pai ake te mahi a te mata wiri hiri me te pono.
Mā te parenga o te peera me te waewae, ka taea e koe te keri i ngā oma roa ake i ngā reiti weronga mōrahi i roto i ngā mahi hurihuri, i ngā mahi motuka rānei.

He tohunga a Far Eastern ki ngā mīhini keri, pērā i ngā mīhini tricone, ngā mīhini PDC, te whakatuwhera poka HDD, ngā mīhini tapahi turanga mō ngā momo mahi maha. Kei roto i ngā mahi ko te mara hinu, te hau māori, te tūhura whenua, te keri ahunga, te keri, te keri puna wai, te HDD, te hanga me te turanga...
Hei wheketere mata keri matua i Haina, ko te whakanui ake i te roa o te mahi a te mata keri ko tā mātou whāinga. E ngana tonu ana mātou ki te whakapai ake i ngā mata me ngā reiti urunga teitei. Ko tā mātou kaupapa matua he whakaiti i te utu o te keri-ia-mita. Ko tā mātou whāinga he hoko i te kounga teitei me te utu iti rawa.
