Temperature Effects

PVC-U material is suitable for service temperatures between 0°C and 50°C, it's self-extinguishing and does not support combustion when the source of ignition is removed.

PVC-U material should not be used for continuous service temperatures above 50°C, as deformation of the pipe may result.

Impact Strength

PVC-U pipes and fittings have good impact resistance, however at very low temperatures (eg. Below 5°C) the impact resistance of PVC-U materials is reduced. Hence, when installing PVC-U at low temperatures extra care should be taken when handling and inserting.

PVC-U pipes are however installed in some of the coldest regions of Europe and North America in large quantities without difficulty.

Chemical Resistance

PVC-U sewer 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.

PVC-U materials should not be used with aromatic or chlorinated hydrocarbons, ketones, esters and ethers.
