Schedule 40 Clear PVC

clear-pvc-330x240

Clear Schedule 40 PVC pipe has excellent clarity and is recommended for tubing containment, visual flow and leak detection, and sight glasses.

GF Harvel Clear™ PVC Schedule 40 provides a versatile, cost-effective alternative for many piping applications, particularly those where visual monitoring of processes is critical. GF Harvel Clear™ PVC is corrosion-resistant, has smooth interior walls, is non-contaminating, has good pressure-bearing capability, uses reliable solvent-welded connections, and is easy to handle and install.

GF 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, GF 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.
