Installing a scrolled resilient sheet alongside the inner surface of a fluid conduit

摘要

Provided is a method of installing a scrolled resilient sheet (3) against the inner surface (4) of a fluid conduit (1) using a carrier tool (5) from which the resilient sheet having an average thickness more than 2 mm and an elastic or pseudoelastic recoverable strain of at least 0.6% is released so that the sheet expands with an expansion force which is sufficiently high to allow the sheet to press itself into place alongside the inner surface of the conduit and to remain in place after installation.
