| Abstract: | Characteristics of the synthetic resin and the linear expansion deformation cause of PP-R water supply pipes are discussed, according to the quality problems of PP-R water supply pipes in the water supply project due to the linear expansion. The calculating methods of PP-R water supply pipe deformation int the water supply system and measures for the flexible compensatioon to PP-R water pipes in the installation of the water pipes are also introduced. |
