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.

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.

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.
