Magni Crushable Foam Wrap

Magni Crushable Foam Wrap is designed to be installed around the inner drill casing, which is then immersed within the annulus fluid. As the pressure of the annulus fluid increases, the Magni Crushable Foam Wrap will collapse at a pre-determined pressure and temperature combination, allowing expansion of the annulus fluid and dispersing any potential destructive pressure increases.
