Abstract
A conduit lies on the inside wall of the tubing. A plurality of anchors are located along the length of the conduit, the anchors being activatable between an "active" state when the anchors engage the inside wall and a "neutral" state when the anchors are disengaged from the inside wall.
Claims16
A conduit which is to be installed internally of a continuously coiled tube comprising an internal bore capable of use in the oil industry, said tube being installed by lateral movement of the conduit with respect to the coiled tube said conduit comprising a plurality of anchors along its length, said anchors being activatable between an "active" state in which the anchor engages the internal bore of the tube and a "neutral" state in which the anchor is disengaged from the internal bore of the tube such that in the "active" state lateral movement between the conduit and the internal bore of the coiled tube is prevented in least one of the forward and rearward directions.
A conduit which is to be installed internally of a tube comprising an internal bore capable of use in the oil industry, said conduit comprising a plurality of anchors along its length, said anchors being activatable between an "active" state in which the anchor engages the internal bore of the tube and a "neutral" state in which the anchor is disengaged from the internal bore of the tube, lateral movement of the conduit relative to the tube in one direction causing the anchor to adopt the "active" state, thus causing the anchor to engage the internal bore of the tube and preventing further lateral movement of the conduit relative to the tube, and lateral movement of the conduit relative to the tube in the opposite direction causing the anchor to adopt the "neutral" state thus disengaging from the internal bore of the tube and permitting further lateral movement in said opposite direction.
A conduit which is to be installed internally of a tube comprising an internal bore capable of use in the oil industry, said conduit comprising a plurality of anchors along its length, said anchors being activatable between an "active" state in which the anchor engages the internal bore of the tube and a "neutral" state in which the anchor is disengaged from the internal bore of the tube, such that in the "active" state lateral movement between the conduit and the internal bore of the coiled tube is prevented in at least one of the forward and rearward directions, the length of the conduit exceeding the length of the tube the excess of conduit causing the conduit to form at least one curve or wave within the tube.
