| POLY VINYL CHLORIDE (PVC) PLASTIC PIPE | |||||||||||
| Pressure loss tables are provided for both SDR-PR and | |||||||||||
| Schedule Wall PVC pipe. | |||||||||||
| Unlike many pipes, the standard wall thickness of PVC | |||||||||||
| pipe has a plus tolerance only, ranging from 0.020 in to | |||||||||||
| 0.090 in. Many pressure loss tables use the standard | |||||||||||
| minimum wall (without tolerances) for computation purposes. | |||||||||||
| Since maufacturing processes preclude | |||||||||||
| achievement of this thickness, most all PVC pipe will | |||||||||||
| have a thicker wall and consequently a smaller ID. | |||||||||||
| Accordingly, use of the standard wall to prepare loss | |||||||||||
| tables is not realistic. The loss tables here use | |||||||||||
| a wall thickness which includes one-half of the tolerances. | |||||||||||
| This results in a more realistic average ID. This | |||||||||||
| method of determining ID for calculation of pressure | |||||||||||
| losses is recommended by the Plastic Pipe Institute (PPI). | |||||||||||
| Caution should be exercised to control velocities in PVC | |||||||||||
| pipe to avoid damage from pressure surging (water hammer). | |||||||||||
| Note: PVC pressure loss tables can be used for any | |||||||||||
| controlled OD thermoplastic pipe of the same SDR or | |||||||||||
| Schedule number. | |||||||||||
