Title:
【発明の名称】パイプを修復するチューブ及びその硬化の程度を測定する方法
Document Type and Number:
Japanese Patent JP2001511524
Kind Code:
A
Abstract:
The invention concerns a method for measuring the degree of cure of an object comprising a hardenable wall or plate, in particular a flexible tube (2) for lining a pipe (1) and having a hardenable wall (3). Said method consists in emitting an electromagnetic radiation (11), preferably UV radiation, towards the hardenable wall or plate, in particular inside (16) the flexible tube (2), and in measuring its reflection by the hardenable wall or plate and/or its transmission through it. Preferably, the hardenable wall (3) is enclosed with a layer reflecting electromagnetic radiation (11) and constitutes a layer of the flexible tube (2). By measuring the proportion of the radiation reflected during the interaction with the tube, when the transmission of the hardenable material varies relatively to the electromagnetic radiation according to its degree of cure, it is possible to deduce the degree of cure of the flexible tube.
