Maximum support spacing for PVDF - PolyVinylidene Fluoride - pipes depends on the operating temperature. Maximum spacing between supports at different temperatures can be found in the tables below:
PVDF Pipe - Schedule 40
| Maximum Support Spacing (feet) | |||
|---|---|---|---|
| NPS (inches) | Operating Temperature (oF) | ||
| 80 | 100 | 1401) | |
| 1/2 | 3 1/2 | 3 1/2 | 2 |
| 3/4 | 4 | 3 1/2 | 2 1/2 |
| 1 | 4 | 4 | 2 1/2 |
| 1 1/2 | 4 1/2 | 4 1/2 | 2 1/2 |
| 2 | 4 1/2 | 4 1/2 | 2 1/2 |
PVDF Pipe - Schedule 80
| Maximum Support Spacing (feet) | |||
|---|---|---|---|
| NPS (inches) | Operating Temperature (oF) | ||
| 80 | 100 | 1401) | |
| 1/2 | 4 1/2 | 4 1/2 | 2 1/2 |
| 3/4 | 4 1/2 | 4 1/2 | 3 |
| 1 | 5 | 4 1/2 | 3 |
| 1 1/2 | 5 1/2 | 5 | 3 |
| 2 | 5 1/2 | 5 | 3 |
- 1 ft (foot) = 0.3048 m
- T(oC) = 5/9[T(oF) - 32]
1) For temperatures above 140 oF continuous support of the pipes is needed.
PVDF is recognized by its high mechanical strength and excellent chemical resistance even at higher temperatures.
