BIG OMEGA®

BIG OMEGA®


BIG OMEGA® is the Threaded & Coupled (T&C) connection standard for big diameter (up to 26″ / 660 mm) casing applications. Established in oil and gas fields all over the world, the connection has proven its superior reliability onshore and offshore for more than 30 years. Its ea​sy-stabbing and easy-running robust thread design guarantees quick and reliable, trouble-free application.​

Compared with BTC according to API 5B, BIG OMEGA®​ shows superior performance with regard to quicker and safer string running, axial loads and internal pressure resistance.
