ʻO ka hale hana API o nā ʻāpana ʻoki ʻoki ʻo TCI no ka ʻeli pōhaku paʻakikī

Hoʻokomo ʻia ʻo Tungsten Carbide i uhi ʻia i nā ʻāpana Roller no nā Pōhaku Paʻa Drilling Core Barrel
Hoʻopili piha ʻia nā mea hoʻokomo tungsten carbide ma luna o ka ʻili o nā cones wili, he ʻokoʻa ia mai ka ʻāpana ʻāpana cone hoʻokahi kuʻuna i hoʻokomo ʻia he hoʻolālā groove-inserts-groove.
Hoʻohui ʻia nā ʻāpana ʻōwili me nā ʻāpana ʻelua, ka lima a me ka cone, mai ka nānā ʻana e paʻa ana ka lima i ka cone ma ka lima.
He mea koʻikoʻi nā mea kila o ka lima a me ka cone no ka maikaʻi, hoʻohana mākou i ke kila 15MnNi4Mo no ka cone, a hoʻohana mākou i ke kila 15CrNiMo no ka lima, ʻo ia ka mea kila maʻamau no ka ʻaila luawai tricone bit.
Ma waena o ka cone-diameter 133mm roller cone bit ma Far Eastern, ʻo kēia kumu hoʻohālike ka mea ʻoi loa ka maikaʻi a me ka hana, loaʻa iā mākou nā mea kūʻai maʻamau mai
ʻO Kina ʻāina a me ʻAsia Hema Hema, noi ʻia nā lua hohonu hohonu i nā papahana kumu no nā hale kiʻekiʻe a me ke kūkulu ʻana i ke kaʻaahi.
