Back PVC-O


Iplex Apollo® is a bi-axially oriented PVC pressure pipe for use in water supply infrastructure. Iplex uses two patented process resulting in an exceptionally tough, high performance thermoplastic pipe with greatly enhanced physical characteristics, including greater impact resistance and reduced weight when compared with tother PVC pipes. Apollo® PVC-O pipe also provides increased hydraulic capacity due to its exceptionally smooth and enlarged bore.

Temperature Effect On Pressure Rating

Apollo® pipes are suitable for service temperatures ranging from 0°C and 50°C. For temperatures above 20°C provision must be made for pressure re-rating. These re-rating factors are the same used for PVC-M and PVC-U.

Chemical Resistance

Resistance of PVC-O pipe and elastomeric seals to reaction with or attack by the chemical agents listed in the `Chemical Resistance Guide" has been determined by research, investigation and reference to data from international and local Source.

Information provided is intended as a guide only Due to the complexity of some organic chemical reactions, it is suggested that in critical applications, additional long-term testing be performed.

Data provided should not necessarily be regarded as applicable to all exposure durations, concentrations and working conditions likely to be encountered.

PVC has exceptional resistance to attack from high concentrations of alkalis and acids, except for strong oxidising agents at maximum or near maximum concentrations. The material is not recommended for use with aromatic and chlorinated hydrocarbons, ketones. esters and ethers.
