发明名称 METHOD FOR INSERTING A PIPE LINER
摘要 <p>A method of installing a self-supporting liner in a pipe section having an inner diameter DP. The liner includes a continuous tube (10) of polymeric material (12), a braided sheath (14) surrounding the tube, and an outer jacket (16) surrounding the braided sheath (14). The liner has a relaxed outer diameter that is greater than DP. The diameter of the liner is temporarily reduced by applying a tensile load to the liner, which causes the braided sheath (14) to radially compress the continuous tube of polymeric material. The liner is inserted into the pipe section while maintaining the radially-compressive force on the liner until the liner has been positioned along the desired length of the pipe section. The tensile load is then removed and the liner is maintained in the pipe section until the diameter of the pipe liner relaxes and forms an interference fit with the inner wall of the pipe section.</p>
