Physical Data For Common Size Pipe schedule 40, 80 and large diameter SDR17”

Temperature De-Rating Table

Curing of cement and grout generates sufficient heat to affect PVC strength and performance. When operating at elevated termperatures, the actual values for Collapse Pressure. Burst Pressure and Tensile Strength will be de-rated according to the chart.

Pressure and Strength

Testing methods and procedures used are in compliance with ASTM F-480 standards for thermoplastic pipe in all applicable areas.

Slotted Screens and Open Area

The following tables represent the standard open area for the Driller’s Pipe slotted PVC well screen. All calculations are based on the inside diameter of the pipe which represents the most accurate area and transmitting potential of the screen.
The data represented in these tables is for standard product line, to calculate transmitting capacity in gpm at 0.1 ft/sec flow velocity. Multiply the open area of square inches by 0.31
