Hana ʻia ka paipu casing API e like me ka maʻamau API 5CT. Hoʻohana pinepine ʻia ia i nā hana kūkulu lalo
e hoʻopaʻa a pale paha i nā laina pono mai ka pōʻino.
Nā kikoʻī:
Kūlana: API 5CT.
ʻO ka pahu kila maʻemaʻe a me nā paipu paipu: 114.3-406.4mm
welded kila casing a me tubing paipu: 88.9-660.4mm
Nā Ana Ma waho: 6.0mm-219.0mm
Mānoanoa Pā: 1.0mm-30 mm
Ka lōʻihi: max 12m
Mea: J55, K55, N80-1, N80-Q, L80-1, P110, etc.
Ka pilina pili: STC, LTC, BTC, XC a me Premium pili
Hoʻohana nui ʻia ia i nā papahana cementing e lawelawe ma ke ʻano he mea hoʻopaʻa paʻa no ka paia o nā luawai aila a me nā luawai. ʻo ia
hoʻokomo ʻia i loko o kahi luawai a hoʻopaʻa ʻia ma kahi e pale ai i nā hana ʻelua i lalo a me ka luawai mai ka hina ʻana a
e 'ae i ka wai wili e kaapuni a e lawe i ka unuhi.
ʻO ka papa kila nui o API 5CT: API 5CT J55, API 5CT K55, API 5CT N80, API 5CT L80, API 5CT P110. ʻO kēia International Standard
pili i nā pili e like me ISO 10422 a i ʻole API Spec 5B:
puʻupuʻu loloa pōkole pōkole (STC);
loloa loloa loloa loloa (LC);
ka pahu kuʻi kaula (BC);
pahu laina kiʻekiʻe (XC);
ʻaʻole hoʻopilikia i nā paipu (NU);
nā paipu hoʻohaunaele waho (EU);
hoʻohui hui pū (IJ).
No ia mau pilina, ua kuhikuhi kēia International Standard i nā kūlana hoʻopuka ʻenehana no nā hui a me ka pale ʻana i ke kaula.
No nā paipu i uhi ʻia e kēia International Standard, ua wehewehe ʻia ka nui, ka nui, ka mānoanoa o ka paia, nā māka a me nā hoʻopau hopena pili.
Hiki ke hoʻohana ʻia kēia International Standard i nā tubular me nā pilina ʻaʻole i uhi ʻia e nā kūlana ISO / API.
