Nebit we gaz üçin API 5CT J55 örtük

Nebit burawlamakda J55 API örtügi ýa-da turbasy has ýygy duş gelýär. J55 poladyň pesligi sebäpli,
ýalpak nebit we gaz çykarmak üçin ulanylýar. Poladyň beýleki derejeleriniň arasynda arzanlygy sebäpli has giň lezzet alýar
goýmalary. J55 API örtük ýa-da turba, tebigy gaz we kömür metany çykarmakda giňden ulanylýar,
köplenç ýalpak guýularda, geotermiki guýularda we suw guýularynda bolýar.
