发明名称 Composite tubular and methods
摘要 The present invention relates to an apparatus and methods for coupling objects that are displaced from one another. In particular, the present invention relates to an apparatus and methods for providing a connection member, for coupling objects that are displaced from one another, that is able to adapt to changing operating conditions. The connection member is a composite tubular that responds to pressure changes such that when the internal pressure of the composite tubular is changed, the length of the tubular proportionally changes, thereby enabling the composite tubular to do useful work.
