A thermoplastic pipe liner assembly and method for installation in a
pipeline by pulling the pipe liner assembly through the pipeline in a
temporarily folded condition wherein the thermoplastic pipe liner
assembly has a core inner liner, an outer liner with optional grooving
for annular communication, orbitally wound strength and intermediate
layers, two or more tension deformation members to sustain the tension
needed to pull the pipe liner assembly through the pipeline for several
miles and to assist in maintaining the temporarily folded condition. Also
included are optional instrumentation circuits. Also disclosed is a
method for the manufacture of the pipe liner assembly and concurrent
installation in a pipeline.
