FIBERBOND® 20HV-D

The FIBERBOND® 20HV-D Fiberglass Piping Series is a fiberglass reinforced pipe product manufactured by filament winding utilizing polyester and epoxy vinyl ester resins and a 20-mil (0.50mm) liner, suitable for design pressures up to 100 psig (6.9 bar) and temperatures up to 150F (65c).  The Series 20HV-D is identical to 20HV except it is designed for low pressure and atmospheric pressure systems such as drain lines.  The 20HV-D standard product is available in 1" to 24" (25mm - 610mm) nominal inside diameters.  Larger sizes are available up to 60" (1524mm) nominal inside diameter.
