Internally threaded (female) connectors are supplied with AISI 430 stainless steel reinforcing rings for size range 1½ to 4 inclusive. Fitting components are detailed in Table 1. TABLE 1: SUPREME PE METRIC COMPRESSION FITTING COMPONENTS Parts Material of make Fitting image Body, lock nut and thrust ring (thrust ring is black colour, just above conical gasket / O-ring) Grip ring (just above the thrust ring) Conical gasket (black colour O-ring) Virgin Polypropylene block copolymer (PP-B) which has high mechanical resistance and thermal stability over time. Excellent UV resistance of coloured components (blue colour lock nut) is achieved by using premium master batch (grade 8 ASTM D2565) Copolymer polyacetal resin (POM), white colour Reinforcement ring Stainless Steel AISI 430 EPDM (Ethylene Propylene Diene Monomer), hardness 70Sh, black colour (only for female threaded outlets of size 1½ up to and including 4 ) SUPREME range of Metric PE Compression Fittings are characterised by their innovative Balance Sealing System (patent pending). This new sealing system offers improved security especially when joining out of round or damaged or undersized pipe. The added security is achieved while still being easy and fast to install with minimal pipe preparation. 3.1.1 Balance sealing gasket system Poseidon The SUPREME gasket (O-ring, shown in purple in Figures 1 and 2) has an internal conical shape allowing for quick and easy assembly. This external bottom lip of the gasket also benefits the sealing process. When the nut is tightened, the thrust ring pushes against the gasket causing it to deform and compress against the pipe wall, creating a perfect seal. As the nut is tightened further deformation continues, creating a proper level of compression and hydraulic sealing against the pipe even if undersized, oval or slightly scratched.

Water Agencies regard these fittings as good substantial products that perform well. At the time of report preparation no official WSAA field trials had been conducted, however products have been used successfully in local marketplace for the past seven years. Direct sales to Water Agencies including the following: (a) (b) (c) (d) (e) (f) Unity Water SA Water Hunter Water City West Water South East Water Yarra Valley Water Viadux believes there would be little value in undertaking a field trial installation report and request that this requirement be deleted.

WSAA Product Appraisal 1705 28 13 DISCUSSION ISO Type 5 product certification (CMARK) provides confidence that the product continues to be manufactured for compliance with the requirements of AS/NZS 4129. The WSAA Agency Network has not reported any problems with PP compression fittings and these fittings, including the SUPREME range of PE Metric compression fittings have a very good reputation for providing trouble free performance. Compression fittings rely on interface pressure being maintained between the elastomeric seal and the PE pipe surface to maintain a sealed connection. Mechanical fittings, including compression fittings are normally used on PE pipe DN 110. Mechanical fittings are also normally used for repairs or changes to the pipeline as the pipe surface preparation requirements are less stringent than electrofusion. Some water agencies consider the smaller PE pipe and compression fittings used for main to meter property services as plumbing products and they are not included in Water Agency infrastructure. Many agencies use minor size PE mains in culde-sac installations and find PP compression fittings adequate and fit for purpose. The AISI Grade 430 stainless steel used as the reinforcing ring for the female threaded components of size 1½ to 4 inclusive is regarded as having good corrosion resistance. WSAA nominates Grade 316 stainless steel for buried situations to provide a high level of corrosion resistance. Stainless steel Grade 430 will be adequate in most buried situations but agencies should be aware of the ground conditions. SUPREME PE Metric Compression Fittings with the stainless steel reinforcing ring should be installed in conditions that provide a less aggressive environment. A high resistivity sand or granular embedment is recommended to minimise the likelihood of corrosion. Note: A high resistivity material is defined as one that has a resistivity greater than 50 ohm meters when tested in accordance with AS 1289.4.4.1. In regard to the SS reinforcing ring material, Viadux has offered the following comments. The purpose of the SS reinforcement ring is to increase hydraulic and mechanical strength of the thread, particularly in presence of high pressure and mechanical stress of the outlet, for example continuous vibration to the threaded connection or an oversized male thread connection. SS reinforcement rings are not required for compression fittings for female threads ½ - 1¼ because the plastic thickness of the outlet has the hydraulic and mechanical strength to resist the pressure and mechanical stress. For thread sizes 1½ - 4 a SS reinforcement ring is important as the plastic thickness is proportionally smaller while the integral pressure stress applied to the thread is greater than the smaller sizes (½ - 1¼ ). As previously stated, we do not believe that the Australian Water Utilities install 1½ - 4 threaded compression fittings as majority of such fittings installed by Water Utilities are ½ - 1¼ which do not require a SS reinforcing ring to meet hydraulic and mechanical strength required for the various applications such as water mains in cul-de-sacs, mains-to-metre property services, pressure sewerage networks and treatment plants. Viadux add that their major competitors globally such as Plasson and GF+ offer the same grade of SS reinforcing ring as SUPREME. Electrofusion (EF) jointing of PE pipelines offers a permanently sealed and jointed system, if the electrofusion welding is done correctly. The EF jointed PE pipeline has the potential to have life expectancy equal to and in some cases well beyond other pipeline materials and jointing systems. The PE material is corrosion resistant and correctly made joints are permanently fused to provide a high level of joint integrity against leakage and/or infiltration over the long-term. Similar to other plastic pipe systems, PE is susceptible to fatigue from cyclic pressure changes and additional design considerations must be made if used in a pumped pipeline. Refer to WSAA Technical Note TN4 and design material available from Viadux and SAB S.p.A.

WSAA Product Appraisal 1705 29 PE pipelines are susceptible to permeation of specific organic chemicals (as are other pipeline systems) and care must be exercised if designing for installation in contaminated ground and/or brownfield sites. Seek further advice from Viadux regarding such installations. 14 OUTCOMES OF EXPERT PANEL PRODUCT REVIEW Comments received by members of the Expert Panel during the peer review period have been addressed in this version of the Report. 15 LIFE EXPECTANCY Polypropylene (PP) compression and push fit fittings and polyethylene (PE) electrofusion fittings are designed on the basis of 50 year extrapolated material test data. For correctly manufactured and installed systems, the actual life cannot be predicted, but can reasonably be expected to be well in excess of 100 years before major rehabilitation is required. This rating is only a general guide to life expectancy and may vary with the quality of installation workmanship, system operating conditions, operating environment and other site specific factors. 16 FUTURE WORKS Within six months of publication of this report, Viadux has to submit the following: (a) (b) The ISO 9001:2015 Quality Management System Certificate for Viadux s new business location at Level 3, 60 Macquarie St, Parramatta NSW 2150.
