ʻO ka ʻāpana pōhaku TCI IADC537 7 1/2” (190 mm)

ʻO nā ʻāpana wili pōhaku API TCI kūʻai nui i ka waihona mai ka hale hana Kina no nā mīkini wili.
Wehewehe ʻana o ka Bit:
IADC: 537 - ʻO ka bit bearing i hoʻopaʻa ʻia me ka puke pai TCI me ka pale gauge no nā ʻano palupalu a waena me ka ikaika compressive haʻahaʻa.
Ikaika Hoʻopaʻa:
85 - 100 MPA
12,000 - 14,500 PSI
Wehewehe ʻĀina:
Nā pōhaku paʻakikī waena a me nā pōhaku ʻāpala e like me nā one one me nā kaha o ka quartz, ka pōhaku limestone paʻakikī a i ʻole ka chert, nā ʻonika hematite, nā pōhaku abrasive paʻakikī, i hoʻopaʻa maikaʻi ʻia e like me: nā one one me ka mea hoʻopaʻa quartz, nā dolomites, nā shales quartzite, ka magma a me nā pōhaku metamorphic coarse grained.
Hiki iā mākou ke hāʻawi i nā ʻāpana TCI i nā nui like ʻole (mai 3" a 26") a me ka hapa nui o nā code IADC.
