Materiaali virtauskanavien, kuten putkien korjaamiseksi ja materiaalin käyttö

摘要

In a procedure for repairing flow channels, e.g. piping, a pipe-shaped piece of flexible material 2 is placed on the channel's 1 inner surface, which material is made up of a hardenable substance and a reinforcement layer, and the hardenable substance is then hardened. The reinforcing layer 5 is a sheet formed of continuous filament fibres - such as glass fibres - and on which is fixed a felt layer 6 consisting of fibres in which felt layer the liquid hardenable substance is absorbed before the material 2 is placed in the channel 1. <IMAGE>
