George Fischer PVC Schedule 40 Pressure Rating
1) Figures for Pressure Rating at 73ºF are rounded off from actual calculated values, and are the same as found in ASTM D-1785. Pressure Ratings for other temperatures are calculated from 73ºF values. 2) Pressure Rating values are for PVC pipe, and for most sizes are calculated from the experimentally determined Long-Term Strength of PVC extrusion compounds. Because molding compounds may differ in Long-Term Strength and elevated temperature properties from pipe compounds, piping systems consisting of extruded pipe and molded fittings may have lower pressure ratings from those shown here, particularly at the higher temperatures. Caution should be exercised in design of systems operating above 100ºF. 3) The pressure ratings given are for solvent-cemented systems. When adding valves, or other components, the system must be derated to the rating of the lowest component. (Pressure ratings: molded or cut threads are rated at 50% of solvent-cemented systems; for valves, see manufacturer's recommendations.) George Fisher Schedule 40 PVC Price List.
