Harvel Clear pipe and fittings are manufactured in IPS sizes to
Schedule 80 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 at elevated temperatures. Refer to the table below for dimensions, tolerances and pressure ratings.
