4 WSAA Product Appraisal PA 05/06.8 Georg Fischer Pty Ltd Alprene Compression Fittings 1 EXECUTIVE SUMMARY Georg Fischer - Alprene PP Compression Fittings have Class 16 pressure rating (20ºC), and are product certified for compliance with AS/NZS Alprene compression fittings are designed for jointing PE pipe (AS/NZS 4130) including PE 80 and PE 100. Alprene compression fittings are used for new PE pipe jointing and in repair situations, wet areas or where fusion jointing is not possible. In all sizes of Alprene compression fittings there is no need to disassemble the fitting. After having loosened the nut, the pipe can be introduced directly to the stop (push-fit) and the nut tensioned. Repair couplings do not have a stop and can be slid completely onto the pipe and back over the repair section. The range of Alprene compression fittings includes plain couplings, repair couplings and reducing couplings, tee s, 90 elbows and end caps in many sizes. There are also male and female adaptors with ¾" and 1" BSP threaded outlets. The female threaded outlets have a Grade 430 stainless steel reinforcing ring (see Section 12 Discussion). Sizes suitable for the water industry include; DN s 25, 32, 50, 63, 90 and larger if appropriate. George Fischer imports the Alprene PP Compression Fittings from their Alprene manufacturing site in Castel Maggiore, Italy. Alprene has a worldwide reputation as a quality producer of compression fittings. PP compression fittings are a mature product in the Australian water industry and such fittings are approved by many water agencies simply based on product certification. Water agencies regard these fittings as good substantial products that perform well. For information on quality polyethylene pipeline design, installation and testing processes refer to the WSAA Polyethylene Pipeline Code - WSA 01. Based on the AS/NZS 4129 test regime this product has been rated B Life expectancy in excess of 50 years before major rehabilitation. This rating is only a general guide to life expectancy and may increase or decrease as a result of the quality of installation, system operating conditions, operating environment and other geographical and site specific factors. The appraisal concludes that: The Georg Fischer Alprene compression fittings are fit for purpose and suitable for use in water supply and sewer pressure and vacuum systems. The quality endorsed company status of Georg Fischer and product certification of the Alprene compression fittings range has been adequately addressed to the satisfaction of WSAA Appraisal Network. 1.1 RECOMMENDATION It is recommended that WSAA members and associates accept/authorise the Georg Fischer Alprene Compression fittings as specified on the StandardsMark Schedule.

5 WSAA Product Appraisal PA 05/06.8 Georg Fischer Pty Ltd Alprene Compression Fittings 2 THE COMPANY Georg Fischer imports the Alprene PP Compression Fittings from their Alprene manufacturing site in Italy. Alprene is located in Castel Maggiore (BO) and was founded in 1956 as an engineering company specialising in turn key irrigation projects. Alprene has experienced continuous growth and recent years have seen the process of transformation with the integration into the Swiss company Georg Fischer. The entry into this group allowed Alprene to cover new markets through a larger and wider sales force. Alprene is now established as a quality producer of compression fittings worldwide. Additional Alprene company and product information is available on their web site at; Georg Fischer is headquartered in Schaffhausen, Switzerland and additional company and product information is available in the Overview (PA 05/06.0) of this appraisal series and on their web site at; 3 THE PRODUCT Georg Fischer - Alprene PP Compression Fittings have Class 16 pressure rating (20ºC), are manufactured to ISO 14236; DIN 8076/3 and are product certified for compliance with AS/NZS 4129 by SAI Global, Standardsmark Licence No. SMK1157. Alprene compression fittings are used for new PE pipe jointing and in repair situations, wet areas or where fusion jointing is not possible. Alprene compression fittings are designed for jointing PE pipe (AS/NZS 4130) including PE 80 and PE 100. In all sizes of Alprene compression fittings there is no need to disassemble the fitting, after having loosened the nut, the pipe can be introduced directly to the stop (push-fit) and the nut tensioned. Repair couplings do not have a stop and can be slid completely onto the pipe and back over the repair section. Alprene compression fittings up to size DN 63 have a pre-lubricated double lip gasket in NBR which can compensate for ovalized, chipped, damaged or undersized pipe. Once the pipe has been inserted, the double lip gasket covers a wide surface to provide a constant contact with the pipe. For sizes from DN 75 to DN 110 a special spring cushion type gasket is used to allow simple insertion of the pipe. ( See brochure in Appendix A ) The range of Alprene compression fittings includes plain couplings, repair couplings and reducing couplings, tee s, 90 elbows and end caps in many sizes including DN 25, 32, 50, 63, 90 and larger as appropriate. There are also male and female adaptors with ¾" and 1" BSP threaded outlet. The female threaded outlets have a Grade 430 stainless steel reinforcing ring (see Section 12 Discussion). Alprene compression fittings are removable and suitable for reuse. The nuts on this type of compression fitting are usually tightened by hand although, GF can supply installation wrenches for easy tightening and loosening. GF Alprene compression fittings are available with either blue or black nuts depending on the supply source. Lilac nuts are available to order to depict recycled water.

Georg Fischer Alprene S.R.L. fittings are product certified by SAI Global, StandardsMark Licence No. SMK1157 for compliance with AS/NZS The Licence and Schedule are shown in Appendix B. The Licence and Schedule can also be seen at the SAI Global web site at: The Georg Fischer Alprene compression fittings also has many international approvals including DVGW, SVGW, KIWA, WRAS, JASWIC, NSF and others. 6.2 COMPLIANCE WITH APPRAISAL REQUIREMENTS Product Certification provides some confidence that the products are manufactured for compliance with the requirements of the nominated Standard (AS/NZS 4129). 6.3 WSAA AGENCY NETWORK REQUESTS The Network made no specific requests with respect to the Alprene PP compression fittings beyond compliance with AS/NZS FITTING INSTRUCTIONS, TRAINING AND INSTALLATION Georg Fischer provides a 4 page instruction brochure demonstrating the assembly and working diagrams of the seals for both the DN 16 DN 63 range and the DN 75 DN 110 range. The descriptive pages are shown in Appendix A. The GF Alprene Catalogue also contains a full description and exploded view of the fittings plus assembly instructions for both the smaller and larger sizes. PP compression fittings are a mature product in the water industry and should require minimal instruction for installation. For the overall design, installation, pipeline testing and installer training requirements for PE pipeline systems refer to the WSAA Polyethylene Pipeline Code - WSA 01 available for purchase at the WSAA web site 8 PRODUCT MARKING Product marking is in compliance with AS/NZS 4129 and includes: Manufacturers Name or registered Trademark; Date or batch code for traceability; Nominal size (DN); 5 September Issue 1

9 WSAA Product Appraisal PA 05/06.8 Georg Fischer Pty Ltd Alprene Compression Fittings Material identification (abbreviated); Pressure Class (PN); The number of the standard (AS/NZS 4129) and StandardsMark logo. 9 PACKAGING AND DELIVERY Individual Alprene Fittings are packed in transparent protective bags and contained in carton boxes. Each carton or protective package clearly indicates its contents. All fittings are packaged to allow use on site without additional cleaning. Where only one type of product is packaged in a bag or carton box, a label showing the manufacturer identification, the description of the product, a line drawing of the product, the relevant size and the quantity is on each package. 10 WATER AGENCIES EXPERIENCE / FIELD TESTING REPORT PP compression fittings are a mature and widely installed product in the Australian water industry and such fittings are approved by many water agencies simply based on product certification. Water agencies regard these fittings as good substantial products that perform well. 11 PRODUCT WARRANTY The products are covered by the normal commercial and legal requirements of The Trade Practices Act 1974, which covers manufacture to the relevant Standard. 12 DISCUSSION The Grade 430 stainless steel used as the reinforcing ring for the female threaded components is a plain chromium Martensitic stainless steel with nominally 17% Cr and 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. GF 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 The WSAA Agency Network has not reported any problems with PP compression fittings and these fittings, including Alprene, 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 90. Mechanical fittings are also normally used for repairs or changes to the pipeline as the pipe surface preparation requirements are less stringent. 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 cull-de-sac installations and find PP compression fittings adequate and fit for purpose. For information on quality polyethylene pipeline design, installation and testing processes refer to the WSAA Polyethylene Pipeline Code - WSA September Issue 1
