Hoʻohana nui ʻia nā paipu Drill i ka mining, geological exploring a me nā ʻano hana wili (wai, ʻaila, gas, etc.ʻO kā mākou mau paipu hoʻoheheʻe e like me ka paipu wili kila, ka paipu hoʻoheheʻe mining, ka paipu luawai wai, ka paipu ʻaila ʻaila, ka paipu hoʻoheheʻe API, ke koʻokoʻo DTH, ke koʻokoʻo wireline drill, etc.
ʻO nā hiʻohiʻona koʻikoʻi o kahi paipu DTH kiʻekiʻe ka lōʻihi, pololei a me ka hoʻokele.
1.Pipe kino: huki anu anu seamless paipu.No laila, loaʻa ka nui kūpono o ka paipu, ka mea kikowaena maikaʻi.
2. Ua like ka papa o ke kino paipu me Sandvik.
3.Thread connector : Heat and Nitrogen treatment , no laila ʻoi aku ka lōʻihi o ka paipu a maʻalahi hoʻi e hoʻouka a wehe.
4.Friction welding .
