Abstract
A pipe liner has an elongate duct of thin laminated thermoplastic layers and remains relatively flexible and folded to a flat form. In this form, opposing sides of the duct are pressed into close proximity aided by folding of the duct, so the liner can be stored efficiently. In use, the liner is inserted into a pipe. The liner is subsequently heated and pressed against the inner surface of the pipe to form a close fit. Once the liner cools, it sets in place providing a close fitting pipe lining. In order to ensure adequate and even heating of the pipe liner during installation, heating is provided within the liner. The heating may comprise: a plurality of conductive filaments; electromagnetic susceptor material; or a plurality of magnetic particles.
