Product introduction
MATERIAL:
Inch rigid PVC pipes and fittings are manufactured from unplasticized PVC plastic compounds.
APPLICATION FIELDS:
Suitable for water supply systems in the following applications:
- Drinking water distribution.
- Water supply and irrigation systems in agriculture.
- Industrial pipeline systems.
- Wastewater drainage systems, rainwater drainage, ...
These pipe systems are selected underground or above ground, installed inside or outside the house and must be protected from sunlight directly.

WORKING PRESSURE:
Working pressure is the maximum allowable pressure for water temperatures up to 45°C. Working pressure is calculated according to the formula:
Plv= K x PN
Where:
Plv: Working pressure.
K: Pressure drop coefficient for water temperature, K is determined as in table 1a or figure 1a
PN: Nominal pressure.
