Abstract
A pipeline isolation tool [] and method of its use includes a plugging head [] having a seal [] to sealably engage a pipe wall; a fluid-activated cylinder [] located on one side of the seal and moveable in an axial direction; metal support segments [] located on another side of the seal and moveable in a transverse direction radially outward and inward; the metal segments including a concave portion [], a portion [] of the seal residing within the concave portion when unset and set. When in a seal unset position a portion [] of the seal is covered by adjacent metal support segments of the plurality. When in a seal set position the portion of the seal is exposed between the adjacent metal support segments. The seal is self-energizing, its actuating force being in a same direction as a force from isolation pressure.
