Mata keri API tricone IADC537 14 3/4″ (374mm) mō te toka mārō

E ai ki te rauemi tapahi, ka taea te wehewehe i te mata tirocne ki te mata TCI me te mata niho maitai. Ko te mata API TCI tricone. Ko te IADC517 14 3/4" (374mm) he momo peera hiri rapa/elastomer me te peera hiri konganuku. Ka tūtohu mātou kia whiriwhiria e mātou ngā mata peera hiri mata konganuku mō ngā puna toka hohonu me ngā hanganga pakeke. Mō te keri poka hohonu rawa, ka tūtohu mātou i ngā mata tricone hiri mata konganuku i te hohonu o te keri neke atu i te 1000 mita. Mō te keri poka pairati kore-awaawa tawhiti neke atu i te 300 mita te roa ka tūtohu mātou i ngā mata tricone hiri mata konganuku. Mō te keri puna wai, te keri puna pāpaku, ngā kaupapa keri poka pairati kore-awaawa tawhiti poto rānei, he pai ake te mahi utu o ngā mata tricone hiri elastomer (rapa).
He ngawari, he pakeke waenga, he pakeke rawa rānei te pakeke o ngā toka, he rerekē pea te pakeke o tētahi momo toka, hei tauira, he kōhatu kirikiri, he kōhatu kirikiri ngohengohe, he kōhatu kirikiri waenga me he kōhatu kirikiri pakeke, he kōhatu kirikiri waenga me he kōhatu kirikiri pakeke, me ētahi atu.
He mea tino nui te whiriwhiri i ngā mata keri kohatu tika i mua i te tīmatanga o te kaupapa. Ko te IADC517 te nuinga mō te keri i ngā kohatu ngohengohe, ko te IADC637 mō te keri tino uaua.
I roto i te kaupapa keri, he 15 tau a Far Eastern me te neke atu i te 30 whenua o te wheako ratonga ki te whakarato i ngā mata keri me ngā wairua keri matatau mō ngā tono maha. Kei roto i ngā tono ko te mara hinu, te hau māori, te tūhura whenua, te keri awa, te keri, te keri puna wai, te HDD, te hanga, me te turanga. Ka taea te whakarite i ngā momo mata keri kia rite ki ngā hanganga toka rerekē nā te mea kei a mātou ake wheketere tohu API me ISO mō ngā mata keri. Ka taea e mātou te whakarato i te otinga a tā mātou miihini ina taea e koe te whakarato i ngā āhuatanga motuhake, pēnei i te pakeke o ngā toka, ngā momo taputapu keri, te tere hurihuri, te taumaha o te mata me te taipana. Ka āwhina hoki mātou ki te kimi i ngā mata keri e tika ana i muri i tō whakamōhio mai ki a mātou mō te keri puna poutū, te keri whakapae rānei, te keri puna hinu, te keri Kore-Keri, te whakatō turanga rānei.
He tohunga a Far Eastern ki ngā mata wiri, pērā i ngā mata tricone, ngā mata PDC, te whakapuare poka HDD, me ngā taputapu tapahi roera turanga mō ngā momo mahi rerekē.
Hei wheketere mata keri matua i Haina, ko te whakanui ake i te roa o te mahi a te mata keri te whāinga. E ngana tonu ana mātou ki te whakapai ake i ngā mata me te tere uru teitei. Ko tā mātou whāinga he hoko i te kounga teitei me te utu iti rawa.
