a substantially cylindrical pipe string comprising a longitudinal axis extending in a first direction and a plug housing;
a disintegratable plug element disposed within the plug housing and configured to move in the direction of the longitudinal axis from a first position to a second position;
an axially movable annular seat element comprising an angled contact surface disposed adjacent the disintegratable plug element;

a shear element configured to prevent movement of the disintegratable plug element from the first position to the second position until the plug is subjected to a predetermined axial force;
a stationary annular seat element axially spaced from the disintegratable plug;
a seal element arranged to prevent fluid from flowing in an axial direction past the disintegratable plug element; and
a loading device configured to break the disintegratable plug element after it has moved to the second position.
