Installasjon av en opprullet, fjærende plate langs den indre overflate av en fluidledning

摘要

A scrolled resilient sheet (3) is installed against the inner surface (4) of a fluid conduit (1) using a carrier tool (5) from which a 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 forse 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.
