Using PE-modified slip liners to rehab gas distribution pipes. C.H. Popelar et al. Pipeline Gas J., December 1997, 224(12), 40--44.
Trenchless technology using a modified slip lining process is described for rehabilitating steel and cast iron pipes with polyethylene liners. Before insertion the PE-liner is reduced in diameter using reduction rollers as in the Rolldown, Tite Liner, and UltraPipe procedures, or by using a reduction die as in the Swagelining process. Material testing is reviewed. Results from constant strain rate tests, constant strain rate/recovery tests and creep/recovery tests are described and illustrated. Installation guidelines are presented. Liner design, host pipe inspection, installation temperature effects, liner diametral reduction, and allowable axial insertion stress are discussed.
