Stretch-resistant liners for lining pipes, pipes lined with stretch-resistant liners, and methods for lining pipes with stretch-resistant liners. The liners (10) are made from a lamination that includes a sealing layer (12), a strength layer (14) of stretch-resistant woven material that overlies the sealing layer, a support layer (16) of non-woven resin-impregnated material that overlies the strength layer, and a barrier layer (18) that overlies the support layer. The lamination is rolled (20) into a tube and inverted when inserted into a pipe (22) so that the barrier layer (18) is the layer that abuts the interior wall of the pipe, the support layer (16) underlies the barrier layer, the strength layer (14) underlies the support layer and the sealing layer (12) underlies the strength layer and is contacted by materials flowing through the pipe. |
