ʻO ka Tungsten Carbide Insert Bit IADC537 8 1/2″(215.9mm)

Wahi a ka mea ʻoki, hiki ke hoʻokaʻawale ʻia ka ʻāpana tirocne i ka ʻāpana TCI a me ka ʻāpana Steel Tooth Bit.
He pōkole ʻo TCI no Tungsten Carbide Insert, ʻo ka tungsten carbide kahi mea paʻakikī maʻamau i ke kahua ʻeli pōhaku, ʻo kekahi mea ʻē aʻe he daimana.
ʻO nā mea hoʻokomo ke ʻano o nā niho Tungsten Carbide e kūpono ana ma nā cones o nā ʻāpana cone roller drilling rotary. .ʻO ka ʻāpana tricone API TCI. ʻO ka IADC537 8 1/2" (215mm/216mm) he ʻano bearing Rubber / Elastomer sealed a me ka bearing Metal sealed. Manaʻo mākou e koho mākou i nā ʻāpana bearing sila maka metala no nā lua pōhaku hohonu me nā ʻano paʻakikī. No ka ʻeli ʻana i ka lua hohonu loa, ke paipai nei mākou i nā ʻāpana tricone bearing sila maka metala ma ka hohonu o ka ʻeli ʻana ma mua o 1000 mika, No ka pōhaku paʻakikī a me ka ʻeli ʻana i ka lua pilot trenchless mamao loa i ʻoi aku ka lōʻihi ma mua o 300 mika ke paipai nei mākou i nā ʻāpana tricone bearing sila maka metala. No ka ʻeli ʻana i ka lua wai, ka ʻeli ʻana i ka lua pāpaʻu a i ʻole nā ​​papahana ʻeli lua pilot trenchless mamao pōkole, ʻoi aku ka maikaʻi o ka hana kumukūʻai o nā ʻāpana tricone bearing sila maka elastomer (rubber).
