Features and Benefits
PVC is formed by the combination of chlorine, carbon and hydrogen in the form of polymer chains. PVC-M is formed by the addition of compatible modifying agents to the PVC matrix, forming an alloy rather than a copolymer. The addition of modifying agents increases the ductility while virtually retaining the same material strength.
The modifying agents significantly improve toughness,impact properties and resistance to crack growth. The change in material matrix gives more ductile behaviour and thus enables the factor of safety for PVC-M pipes to be lower than PVC-U pipes. Short and long term tests on Vinidex Hydro® pressure pipes have demonstrated consistently ductile behaviour, particularly in the presence of notches. The reduced factor of safety enables higher allowable stress levels, reduced wall thickness providing greater hydraulic efficiency.
Stabilisers are an integral component of PVC-M manufacture, maintaining thermal stability during the extrusion process. All Vinidex pressure pipes including Vinidex Hydro® PVC-M are manufactured using stabilisers and other additives that do not contain any lead or cadmium compounds.
Improved Material Performance – The alloying of PVC with modifying polymers achieves improvement in resistance to cracking. The result is the minimisation of the effect of stress concentrators such as scratches. With a consequent reduction in the factor of safety, higher wall stresses are allowable which lead to reduced wall thickness.
Hydraulic Efficiency – The increased internal diameter for a given external diameter makes Vinidex Hydro® a more efficient conduit than PVC-U and ductile iron.
Light Weight – PVC is already recognised as the lightest and easiest of pipeline materials to handle. Vinidex Hydro® further increases this advantage. Depending on size and class, weight savings in excess of 10% over PVC-U is available.
System Compatibility – Whether supplied in Series 1 for the irrigation industry or Series 2 for the water industry, Vinidex Hydro® is fully compatible with existing pipeline systems with the full range of valves and fittings available.
Corrosion resistant – Hydro pipes are totally unaffected by soil and water chemicals and will not be affected by anything that can normally be found in sewage effluent.
No adverse effect on water quality – Hydro pipes will not affect the taste, smell, appearance or health aspects of drinking water.
