Mea Hana no 12 1/4 ʻīniha IADC537/747 Tricone Single Roller Cone Bit/Drill Bit Plam no ka Piling/Rotary/HDD Drilling

Ma muli o ke kōkua maikaʻi loa, nā ʻano mea kiʻekiʻe like ʻole, nā kumukūʻai hoʻoikaika a me ka hoʻouna kūpono, hauʻoli mākou i kahi kūlana maikaʻi loa i waena o kā mākou mea kūʻai aku. He hui ikaika mākou me ka mākeke ākea no ka Mea Hana no 12 1/4 Inch IADC537/747 Tricone Single Roller Cone Bit/Drill Bit Plam no Piling/Rotary/HDD Drilling, Ma ke ʻano he ʻoihana koʻikoʻi o kēia ʻoihana, ke hoʻoikaika nei kā mākou hui e lilo i mea hoʻolako alakaʻi, ma muli o ka hilinaʻi o ka maikaʻi loea a me ka hui honua.

Wehewehe Huahana

ʻO nā ʻāpana wili tricone pilot TCI HDD kūʻai nui me ka bearing sila metala i loko o ka waihona me ke kumu kūʻai hoʻemi ʻia mai ka hale hana Kina
Wehewehe ʻana o ka Bit:
IADC: 537 - ʻO ka bit bearing i hoʻopaʻa ʻia i 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 Far Eastern Drilling ke hāʻawi i nā ʻāpana tricone HDD i nā nui like ʻole (mai 3” a 26”) a me ka hapa nui o nā code IADC.
