发明名称 Undulated conduit anchored in coiled tubing.
摘要 <p>A conduit (2) is disclosed for installation internally of a coiled tube (1), said conduit (2) lying on the inside wall (3) of the tubing. A plurality of anchors (20) is located along the length of the conduit, the anchors (20) being activatable between an "active" state when the anchors (20) engage the inside wall (3) and a "neutral" state when the anchors (20) are disengaged from the inside wall (3). The invention also extends to an anchor for use in the conduit and a method of installing the conduit (2) in the coiled tube (1). &lt;IMAGE&gt;</p>
