ʻO ka paipu drill, ʻo ke ʻano pōkole o lalo o ka paipu drill hole, he ʻano ʻano koʻokoʻo pālahalaha waho.Hoʻohana nui ʻia ia i ka rotary percussive drilling i loaʻa nā kinoea a me nā wai.ʻO kona mau mea nui he paipu (koʻokoʻo) kino a me ka hui.

Hana ʻia kā mākou paipu hoʻoheheʻe i lalo ma muli o nā kūlana API.A e like me nā koi kikoʻī, hāʻawi pū mākou i kēia ʻano paipu drill i nā kikoʻī ʻokoʻa Kina a me ʻAmelika.

E like me kona mau pono, loaʻa iā ia nā hiʻohiʻona o ka rigidity nui, ka hiki ke hoʻopaʻa maikaʻi ʻana, ka papa waho waho, a me ka haʻahaʻa haʻahaʻa a me ke kūpaʻa i ka wā e huli ai.

No ka hoʻopili ʻana, e hoʻopili ʻia kahi pūpū o nā paipu wili e hoʻokahi pahu kila, a ʻo kahi pūʻolo he 9 a 40 mau paipu wili.

Raw Material: Hot rolled seeamless pipe, mai BAO STEEL / TPCO / BAO GANG a pēlā aku, E like me ka nānā ʻana i nā kūlana kūpono, ma o ka mea kanu hana, ka mea kanu hana ʻelua nānā, e hōʻoia i ka maikaʻi o nā mea maka.
