<p>The conduit internal lining method can be carried out in situ, the lining material being injected into a limited space defined in the radial direction by the external wall of a slug and the inside of the conduit, and in the lengthwise direction by a first component fixed at one end of the conduit and a second one travelling in the axial direction of the latter. The lining material is delivered by an injector travelling at the same speed and in the same direction as the second component, as the space fills up with the material. This solidifies as it adheres to the conduit wall.</p> |
