Keri tricone API IADC127 4 5/8 inihi (118mm) hei hoko

Ko ngā mata wiri hiri toka tricone niho rino API rarawe kei roto i te taonga i runga i te utu iti rawa me te kounga pai rawa atu mai i te wheketere Haina.
Whakaahuatanga Moka:
IADC: 127 - Mata pere hiri niho maitai me te tiaki ine mō ngā hanganga ngohengohe me te kaha pēhi iti me te kaha keri teitei.
Kaha Whakapūmau:
0 - 35 MPA
0 - 5,000 PSI
Whakaahuatanga Whenua:
Ko ngā toka tino ngohengohe, kāore i te paparanga, kāore i te pai te kiato pērā i te uku me te kirikiri kirikiri kāore i te pai te kiato, te kōhatu kirikiri mārō, te tote, te gypsum, me ngā waro mārō.
Ka taea e mātou te tuku atu i ngā mata wiri niho mira me ngā mata wiri tricone TCI o ngā rahi rerekē (mai i te 3 7/8” ki te 26”) me te nuinga o ngā waehere IADC.

E ai ki te rauemi tapahi, ka taea te wehewehe i ngā moka kōne e toru ki te moka TCI me te moka Niho Mira.
Ko tētahi atu ingoa o ngā mata tricone niho rino ko te mata tricone niho mira nā te mea ka hangaia ngā niho e te mīhini mira, ko te mata kōne he mea mārō ki te tungsten carbide.
He mea hanga ngohengohe rawa te niho mira IADC127. He mea nui te whiriwhiri i ngā mata keri toka tika i mua i te tīmatanga o te kaupapa.
Ka taea e te pakeke o ngā toka te ngohengohe, te pakeke waenga, te pakeke tino pakeke rānei, ka rerekē pea te pakeke o tētahi momo toka, hei tauira, he toka kōhatu, he toka onepū, he toka kōhatu ngohengohe, he toka kōhatu waenga, he toka kōhatu pakeke hoki te kirikiri, he toka kōhatu waenga, he toka onepū pakeke hoki, me ētahi atu.
