Paipu Drill Kaumaha Kaumaha
ʻO ka paipu hoʻoheheʻe kaumaha kaumaha ka wahi hoʻololi ma waena o ka drill collar a me ka pipe drill.ʻAʻole hiki iā ia ke hōʻemi wale i ka hoʻokumu ʻana i ke koʻikoʻi i ka pili ʻana o ka drill collar a me ka drill pipe, akā e hoʻemi hoʻi i ka lole ma OD.
Hana ʻia ka paipu hoʻoheheʻe kaumaha kaumaha mai hoʻokahi ʻāpana o AISI 4145H paʻa paʻa, mālama ʻia me ka wela piha, kūpono nā waiwai kino āpau me ka API spec7 paʻi hou loa.
He mea maʻamau ka paʻa paʻa paʻa ʻana o ka HWDP ma nā hono ami mea hana a me ka huhū waena.ʻO nā ʻano o ka paʻa paʻakikī ʻo Arnco 100XT a me 100XT.Hoʻopili ʻia nā kaula a pau i ka phosphated, copperized a i ʻole ka hana anu.Hoʻopiliʻia nā pilina a pau me nā mea pale kaula kila i kaomiʻia.Hoʻopili ʻia nā pāʻani āpau me nā lathes CNC - ʻelua-poʻohiwi a me nā kaula kūikawā.
Nā kikoʻī ʻenehana a me nā ʻāpana
