C-PVC pipe is a heat resistant rigid vinyl chloride pipe that dramatically improves the heat resistance of polyvinyl chloride with its excellent chemical resistance, corrosion resistance and construction properties. It has very low thermal conductivity and low heat loss, prevents condensation and prevents damage to walls and structures. In addition, there is no proper leakage current because of good electrical insulation. It is easy to handle because it is lighter than metal products, and it is possible to work even in a narrow space because of easy connection and separation. In addition, there is no corrosion or scale, and it does not obstruct the water hole of the sprinkler head like iron pipe, so it can be used semi-permanently.
