Corrosion resistance

The major finding of a recent study is that PVC Pipes have the lowest overall failure rate when compared to cast iron, ductile iron, concrete and steel pipes. PVC pipes won’t rush or corrode over time because it does not react with air and water the way metal does which results in a significantly longer lifetime the pipe.

Chemical resistance

PVC pipes exhibit excellent resistance to a wide range of chemical reagents in temperatures up to 50 0 C. PVC pipes can be used indoors or to transport chemicals or waste products without risk of materials eating through the pipe.

Operating temperature Up to 60 o C
