DIMAX XTREME Z+ combines the best features of Viadux’s proven ductile iron pipeline systems with materials that provide high resistance to chemical attack and abrasion internally and DIMAX Z+ corrosion protection system for Ductile Iron Pipe externally.

Now designers, installers and operators can have confidence, not only in the proven mechanical strength of ductile iron, but in its enhanced ability to resist internal attack from aggressive fluids such as sewage and industrial waste.

This is achieved by using calcium aluminate cement (CAC) in lieu of sulphate resisting (SR) cement in the barrel lining. This is complemented by the application of an epoxy coating in the pipe jointing region. CAC is an effective lining for aggressive fluids with extreme pH values and/or abrasive solids.

And with DIMAX Z+ active corrosion protection system, corrosion protection is no longer dependent on careful and thorough site application of PE Sleeving by installation contractors. Being a factory applied corrosion protection system, Z+ is quality assured through controlled automated application and in line measurement and testing covered by ISO9001 certified quality management systems.

DIMAX XTREME Z+ with Zinc-Aluminium-RareEarth technology will extend the service life of your pipeline and reduce on-site handling saving you TIME and MONEY by eliminating the requirement for polyethylene sleeving.

Available in Class PN35 and PN30/25 DIMAX XTREME Z+ matches the maximum flange table rating of the most common water industry applications and provides a cost effective solution for lower pressure applications.




The DIMAX Z+ coating system benefits from the 'active' properties of the Zinc-Aluminium-RareEarth alloy when in contact with the soil in that it:

Provides a long term barrier by forming a stable all-round protective layer (zinc hydroxides) covering the entire surface of the buried pipe;

Restores the protective layer at points where it has been slightly damaged (impacts during transportation, scrapes when backfilling) through the galvanic effect between the exposed iron and the zinc around the damage.

Zinc Aluminum has long be used in the civil industry as an effective corrosion protection system. Dimax Z+ further improves on this traditional formula to bring you the most
advanced corrosion protection system available. Dimax Z+ has been engineered with a small percentage of rare earth metals to withstand Australia’s aggressive soil conditions.

This unique Zinc-Aluminum-Rare Earth Alloy enhances the galvanic effect that standard Zinc Aluminium creates to actively protect the pipe.
