API 5CT paipu pahu

ʻO ka pahu he paipu anawaena nui i hui ʻia a hoʻokomo ʻia i loko o kahi ʻāpana wili hou ʻia o kahi lua a maʻamau.
paa me ka sima. A ke hāʻawi nei mākou i nā ʻano Casing Seamless mai 4-1/2''-20'' ma ka papa H40, J55, K55,
N80, L80, C95, P110 etc. ʻO ka lōʻihi o ka Casing ʻo R1, R2, R3, me nā kaula o BTC, LTC, STC. E like me ka ikaika
o ke kila casing hiki ke maheleia i okoa kila kila, hohonu luawai, me ka hoʻohana 'okoʻa kila kila. I loko o ka corrosive kaiapuni
pono nō hoʻi ka casing ponoʻī i ka corrosion kū'ē. I ka complicated geologic kulana wahi i ninau aku i ka casing
loaʻa ka hana anti-collapse.
