PDC HDD (Horizontal Directional Drilling) Drill Bits
wehewehe huahana
Hiki i kēia mau ʻāpana HDD a me nā mea hoʻokomo ke kū i nā wahi paʻakikī āpau a me nā ʻāpana ʻino e hiki ke hoʻolei iā ʻoe. Inā ʻoe e wili ana i ka ʻiliʻili a i ʻole ka lepo, loaʻa iā Grand Construction ka mea hoʻoheheʻe kuhikuhi kūpono a hoʻokomo paha no kāu papahana.
Hiki i nā ʻāpana drill PDC HDD ke wili i ka ʻāpana waena a me ka paʻakikī paʻakikī. Manaʻo ʻia e wili i ka shale, mudstone, Cemented Sandstone a me ka pōhaku carbonate me ka ikaika compressive medium. Loaʻa iā mākou kahi koho nui o nā bits drill HDD, e like me nā bits pilot milled-tooth no nā ʻano palupalu a palupalu. Me ka pale ʻana o ka lining i hoʻopaʻa ʻia, ka metala paʻa ma ka bevel a me ka hoʻokuʻu ʻana o ka cone i loko, hiki i nā bits pailaka ke kū i nā kūlana wili paʻakikī i loaʻa i nā noi HDD.
ʻO kekahi o nā pōmaikaʻi koʻikoʻi o kā mākou HDD drill bits ko lākou hiki ke hoʻokele kūʻokoʻa, e ʻae iā lākou e hoʻokele pololei a hiki i nā noi wili kuhikuhi paʻakikī loa. Inā ʻoe e wili ana ma lalo o ke alanui kūlanakauhale a i ʻole ma lalo o kahi kahawai, hiki iā ʻoe ke hilinaʻi i kā mākou HDD drill bits e hāʻawi i ka hana pololei a hilinaʻi i kēlā me kēia manawa.
Ma waho aʻe o kā lākou hiki ke ʻoki a me ka hoʻokele, hoʻolālā ʻia kā mākou Horizontal Directional Drilling Bits e hōʻemi i ka haʻalulu a hōʻemi i ka ʻaʻahu a me ka waimaka ma kāu mau mea wili, e kōkua ana i ka hoʻonui ʻana i ke ola o kāu mau mea hana a hoʻemi i ka manawa haʻahaʻa ma kāu mau hana wili.
ʻAʻole like me nā ʻāpana alakaʻi PDC maʻamau, hāʻawi kā mākou Grand Construction bits i kekahi mau pono hoʻolālā, me:
ʻO ka hoʻolālā hoʻolālā hoʻonui no ka ʻeli ʻana i ka pōhaku.
ʻO nā stabilizers i kūkulu ʻia no ka hoʻomaikaʻi ʻana i ke kūpaʻa o ke kolamu drill.
ʻOi aku ka nui o nā mea hana PDC no ke ola lōʻihi ma mua o nā pahu drill PDC maʻamau.
Loaʻa kā mākou mau bits alakaʻi HDD maʻamau i ka nui 5-1/2" a me 6-1/2". Hōʻike kēlā me kēia bit i kā mākou hoʻolālā 5-blade lōʻihi a mahalo nui ʻia, me kahi mea hana 13mm PDC, no ka hana ʻoihana, pololei a maikaʻi hoʻi i kēlā me kēia papahana wili pōhaku.
