Pipa selubung adalah komponen struktural utama dari sebuah sumur.Pipa Casing API 5CT berdiameter besar
pipa baja yang berfungsi sebagai penahan struktural untuk dinding sumur minyak dan gas, dan biasanya dipegang
tempat dengan semen.
Casing API 5CT dimasukkan ke dalam lubang sumur dan disemen untuk melindungi kedua formasi bawah permukaan sub
dan lubang sumur dari keruntuhan dan untuk memungkinkan cairan pengeboran bersirkulasi dan ekstraksi berlangsung.
Biaya casing adalah bagian utama dari keseluruhan biaya sumur, jadi pemilihan ukuran casing, grade, konektor,
dan kedalaman pengaturan adalah pertimbangan teknik dan ekonomi utama.
Fitur:
1. Pipa khusus minyak
2. API 5CT standar internasional
