Kaiwhakarato mō ngā mata pātene IADC637 7 7/8” (200mm)
Whakaahuatanga Hua
Ngā mata keri tricone API TCI rarawe me te utu whakaheke i roto i te taonga mai i te kaiwhakarato 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.
Mā ngā momo whirihoranga waipēhi ka tika te horoi i ngā moka me ngā kōhao i roto i ngā mahi maha. Ka taea e ngā pūwero te horoi i te rekereke me ngā niho rekereke e tata ana.
Mā te iti ake o ngā wahi mo ia wāhanga, te iti ake o ngā putanga mai i te poka, me te iti ake o ngā rā hei whakaoti i tō poka, ka iti ake te utu-mō ia putu.
