The casing & tubing of OTTM & OTTG series: exclusively designed and manufactured non API casing for Commonwealth of Independent 
States (CIS). The thread can interexchange with the BC thread of API casing, with which the casing is suitable to the well conditions without
 sealing requirement. OTTG casings add the sealing construction on the jointing part based on the OTTM casings, which made it more suitable 
to the well conditions with sealing requirement
