API 5CT Hoʻopaʻa kila maʻemaʻe a me nā paipu

ʻO ka Pipe Casing he paipu anawaena nui e lawelawe ana ma ke ʻano he mea hoʻopaʻa paʻa no nā paia o nā luawai aila a me ke kinoea, a i ʻole ka luawai. Hoʻokomo ʻia i loko o ka luawai a hoʻopaʻa ʻia ma kahi e pale ai i nā ʻano o lalo o ka ʻāina a me ka luawai mai ka hāʻule ʻana a no ka ʻae ʻana i ka wai wili e kaapuni a lawe ʻia. ʻO nā paipu pahu kila he pā maʻemaʻe a me ka ikaika haʻahaʻa loa o 35,000 psi.

He kuleana koʻikoʻi ka API 5CT pahu aila maʻamau i ka pale ʻana i ka pūnāwai aila mai ka pōʻino ʻia e ka papa ʻaila pāpaʻu a kākoʻo i ka lawe ʻana i ka aila a me ke kinoea. ʻO ka mea hou aku, hiki i ka paipu pahu ke kākoʻo i ke kaumaha o ka papa punawai e pale ai i ka hāʻule. API 5CT casing pipe hōʻoia i ka holomua holomua o ka holoʻokoʻa kaʻina hana wili, ma hope o ia, lawe aila a me ke kinoea mai ka wili ana i ka lepo.
