API 5CT J55 posungira mafuta ndi gasi

The J55 API casing kapena chubu ndizofala kwambiri pakubowola mafuta. Chifukwa cha chitsulo chotsika cha J55,
amagwiritsidwa ntchito popanga mafuta osaya komanso gasi. Chifukwa cha mtengo wake wotsika pakati pa magulu ena azitsulo, amasangalala kwambiri
mapulogalamu. The J55 API casing kapena chubu amagwiritsidwa ntchito kwambiri pochotsa gasi wachilengedwe ndi methane ya malasha,
ndipo nthawi zambiri amapezeka m'zitsime zosazama, m'zitsime zotentha, ndi zitsime zamadzi.

API 5CT J55 Casing Tubing Features

Pamwamba pa ulusi wolumikizira ndi API 5CT J55 Casing Tubing iyenera kukhala yosalala popanda misozi, burr
kapena zolakwika zina zomwe zingakhale ndi zotsatira zoipa pa mphamvu ndi kugwirizana kwapafupi.

API 5CT J55 Casing Tubing imaperekedwa ndi utali wautali kuchokera ku 8m mpaka 13m pamaziko a SY/T6194-96
mwachizolowezi. Komabe, imapezekanso osachepera 6m kutalika ndipo kuchuluka kwake kuyenera kukhala kosapitilira 20%.

Ma deformation omwe atchulidwa pamwambapa saloledwa kuwonekera kunja kwa API 5CT J55 Casing
Kulumikizana kwa tubing.

Kusinthika kulikonse monga kukwapula, kupatukana, tsitsi, mng'alu kapena nkhanambo sikuvomerezeka mkati ndi kunja.
pamwamba pa mankhwala. Zowonongeka zonsezi ziyenera kuchotsedwa kwathunthu, ndikuchotsa kuya sikuyenera
