Vacuum performance of CRP heavy duty PTFE & PFA lined piping systems.

  • 1/2″NB – 8″NB suitable for use under full vacuum to 392º F.
  • 10″ NB  – 12″NB  suitable for use under full vacuum to 302º F.
  • 14″ NB –  Suitable for use under full vacuum to 122º F.
  • With 10″NB – 12″NB lined piping the vacuum resistance drops by 0.725 PSI per 50ºF increase in temperature between 302º F and 392º F. Which means -12.32 PSI (2.17 PSI abs.) at 356°F and -10.87 PSI (3.625 PSI abs.) at 392°F
