De-Rating Factor |
|
The pressure ratings given above are for water, non-shock, @ 73°F. The |
|
1.00 |
73 |
||
specified derating factors for CPVC are suitable for pipe conveying water |
90 |
0.91 |
at elevated temperatures. To determine elevated temperature rating, |
100 |
0.82 |
multiply 73°F [23°C] pressure rating by appropriate factor shown in the |
110 |
0.72 |
table for desired operating temperature. When working near maximum |
120 |
0.65 |
specified temperature, solvent cement joints are recommended in place of |
130 |
0.57 |
threaded connections. Where disassembly is required at elevated |
140 |
0.50 |
temperatures, use Spears® Special reinforced (SR) adapters, flanges, |
150 |
0.42 |
unions or grooved coupling connections. Spears® recommends that only |
160 |
0.40 |
Schedule 80 or heavier wall thickness pipe should be threaded. |
