Chemical Resistance

PVC-U pipes have high resistance to a wide range of chemical reagents. Such resistance, however, is a function of temperature, concentration and pressure.

In general, PVC-U is suitable to convey strong acids, alkalis and aqueous solutions (except those which are strongly oxidising), aliphatic hydrocarbons, fluorides, photographic and plating solutions, brine, mineral oils, fats and alcohols. The suitability of a pipeline for conveying a certain chemical will depend on such factors as the concentration of the chemical in the fluid to be conveyed, temperature, flow rate, the presence of pockets or “dead spots” in the pipeline and other factors.
