The temperature should not exceed 70 degrees, and normal pressure is fine
PVC pipes lack toughness; they are quite brittle and prone to damage, so PPR pipes are a better choice
It can be used. We’ve been using it all along.
Is that so? Could there be leaks at the areas where the PVC is bonded? We’re using an NaOH solution with a concentration of over 50% – will that work?
I’ve never used PPR; what material is it? Is it alkali-resistant? How is it connected?
It’s not at atmospheric pressure, but at room temperature; the pressure is the outlet pressure of the metering pump, around 7.8 kilograms!
