Dual Circulation Sub
 
The Dual Circulation Sub is designed to allow additional circulation capabilities above the tool string by two activation methods. The tool incorporates drop ball activated circulating ports and a burst disc. The pressure at which the tool will open by the drop ball method can be easily adjusted at surface by varying the number of shear pins used. In the event that circulation is lost, pressure can be applied to the tubing to burst the disc allowing a drop ball to be pumped to the circulating sub or disconnect. Burst discs are available in 4,000, 5,000 and 6,000 psi ratings.
