Design Features

1. Interchangeable with API Buttress
2. Internally flush
3. Pin Abutment results in high resistance to over-torque, more than 3 times as high as API Buttress.
4. Pin abutment results in high resistance to compression
5. Gas-tight seal under compression
6. Mill end is made up further than field end to avoid mill end rotation when make up field end
7. Precise make-up position control reduces hoop stress on the coupling
8. User friendly operation on the rig: Make up with torque control like a premium connection

Application

1. Casing for Geothermal Wells
2. Liner for Horizontal Wells
3. Casing for Heavy Oil Recovery such as SAGD
4. Drilling with Casing
