SEHER glass fiber ppr pipe consists 3 layers, the middle layer is strengthening glass fiber, inner layer is hot water material, and the outer layer is imported PP-R. the PR-PPR pipe is better in heat-proof than other ordinary PP-R pipes because its expansivity is only 1/5 of others, it lets the pipe can be bended, better pressure resistance, longer service life, higher intensity and better shock resistance. it is the best choice for the solar energy, heat energy circle system, heater system and running water supply system.
