API tricone drill bits utu IADC216 4 5/8 inihi (118mm)
Whakaahuatanga Hua
4 5/8 "TCI tricone bit e whakamahia nuitia ana i roto i te keri puna wai, te torotoro, te kohao pairati HDD, te puranga turanga, he hoahoa poka jet pokapū, no reira ka taea hoki te mahi mo te keri tohanga whakamuri.
Kua hirihia te kawe, he roa ake te ora mahi i nga paraka roera whanau tuwhera.
Ko tenei momo moka tricone niho rino he kohao pokapū e tika ana mo te keri RC (Whakamuri Whakamuri Circulation keri).
Ka taea e IADC216 tricone bit te keri i nga hanganga uaua ake i te IADC126, ko te whiriwhiri i te IADC tika i runga i te pakeke o nga toka ko te mahi tuatahi o te keri tino pai.Ko Far Eastern Drilling he wheketere whaimana API mo te moka roera tricone.
