PVC-U Pressure Pipe & Fittings (Un-plasticised)
PVC-U pressure pipes and fittings are manufactured from unplasticised polyvinyl chloride polymer (a thermoplastic material) using the extrusion process. PVC-U pipes and fittings were introduced into Australia in the early 1960's and is now widely accepted for use across many applications. Their high strength weight ratio together with exceptional resistance to corrosion or chemical attack make these pipelines ideal for major infrastructure applications.

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.

PVC-U Fittings Range
A full range of SWJ bends, tees, reducers and valve connectors are available for Iplex PVC-U Series 1 pressure pipes with appropriate socketed joints for sizes DN15 to DN375.
Note: The use of imported solvent welded PVC-U fittings with parallel sockets will require gap filling solvent complying with ASTM D-2564. Failure to use the appropriate solvent and cleaner will result in joint failure.
All PVC-U fittings are electrically non-conductive and do not require corrosion protection in aggressive environments.
PVC-U and Crevet® Ductile Iron Fittings
Conventional socketed fittings complying with AS/NZS 2280 - "Ductile Iron Pressure Pipes and Fittings" are generally suitable for use with Iplex's PVC-U Series 1 pressure pipes.
The Iplex Crevet® range of bends, tees, reducers and flange-spigot pieces are available with rubber ring sockets in sizes DN100 to DN375.
Reference should be made to the Water Services Association of Australia WSAA TN2 'Guidelines for the use of non-metallic pipes with ductile iron elastomeric joint fittings'. If in doubt, contact Iplex Pipelines to confirm the Suitability of any particular range of fittings.
Ductile iron fittings can be protected from corrosion with the following:
- Polymeric coated (preferred)
- Cement lining and polyethylene wrap
- Epoxy coating
