Technical Details
Pipe Derating Factor
PVC-U ASTM Plumbing pipes can be used at higher pressure ratings for a water temperature of 23°C. As the temperature of water increases, the working pressure reduces (100% at 23°C, 50% at 45°C and 22% at 60°C). Pipes may be used up to 45°C without adverse effect.
| Service Temperature (°C) | 23 | 30 | 35 | 40 | 45 | 50 | 55 | 60 |
|---|---|---|---|---|---|---|---|---|
| % of Working Pressure | 100 | 90 | 75 | 62 | 50 | 40 | 30 | 22 |
Thermal Expansion
Thermal expansion of PVC is approximately 4.5 to 5 times higher than metallic pipes. For buried cold water lines there is no adverse effect, however exposed pipelines and high temperature fluids require expansion consideration.
δl = α × L × δt
- δl – Change in length (mm)
- α – Coefficient of linear expansion of PVC
- L – Length of pipe (mm)
- δt – Difference between ambient and operating temperature
Jointing Procedure
1. Measuring: Measure the required pipe length and mark accordingly.
2. Cutting: Pipe must be cut square. Angled cuts may cause leakage.
3. Deburring & Chamfering: Remove burrs and apply 10°–15° chamfer.
4. Cleaning: Clean pipe and fitting surface using dry cloth.
5. Check Dry Fit: Insert pipe one-third to half into socket.
6. Solvent Cement: Apply cement evenly to pipe and fitting.
7. Assembly: Join pipe fully and hold till cement sets.
