Schedule 40 Rigid PVC Piping Systems


SCHEDULE 40 - DIMENSIONS

 


Harvel Clear pipe and fittings are manufactured in IPS sizes to Schedule 40 dimensions for optimum performance. This provides sufficient wall thickness for most pressure applications without jeopardizing clarity. As a rigid PVC piping, Harvel Clear PVC maintains its integrity in harsh environments. It is suitable for use in both positive and negative pressure applications (i.e., vacuum service).

As with all schedules of thermoplastic pipe, pressure rating is dependent on the pipe diameter selected as well as the operating temperature of the system. As temperatures rise, the pressure rating of the system decreases. Smaller diameter piping can withstand higher pressures than large diameter piping. Refer to the table below for dimensions, tolerances and pressure ratings.
