API 5CTJeklena cev

APITo je okrajšava Ameriškega naftnega inštituta，Velja za najbolj avtoritativno osebo v naftni in plinski industriji、Najbolj celovito načelo。API 5BinAPI 5CTVečinoma se uporablja za ohišje olja。API 5CTOljno ohišje lahko razdelimo na brezšivne jeklene cevi in varjene jeklene cevi，Varjene jeklene cevi se večinoma nanašajo na ravne jeklene cevi，Oljno ohišje velikega premera je običajno izdelano iz potopljene obločne varjene ravne jeklene cevi。
