API 5CT J55 casing pikeun minyak jeung gas

The J55 API casing atanapi tubing mangrupakeun hiji rélatif umum dina pangeboran minyak. Kusabab kelas baja low of J55,
dipaké pikeun ékstraksi minyak jeung gas deet. Kusabab hargana anu murah diantara kelas baja anu sanés, éta langkung lega
aplikasi. The J55 API casing atanapi tubing loba dipaké dina ékstraksi gas alam jeung métana coalbed,
sarta biasa kapanggih di sumur dangkal, sumur panas bumi, jeung sumur cai.
