Non-rotating cementing top plug is available for both surface launch and sub sea launch applications.
A bottom cementing plug with collet insert on bottom, and threaded type receiver on top of plug.
The top cenment plug features a collet type insert on the bottom end.
The collet feature allows for the bottom plug to latch into the float collar, as well as for the top plug to latch-in to the bottom plug.
Once latched in, right hand rotation during drill out tightens up the engagement of the plugs and
collar, with the threaded profiles on the collet and receiver.
