Alternatives to metal for valves and fittings helping to reduce weight

formulations for potable water and water handling applications. Nymax formulations in PA6, PA 6/6, and other copolymer grades can be made with a wide variety of reinforcements, modifiers, and fillers to enhance physical properties, weatherability and processing. Maxxam polypropylene and polyethylene-based materials are tailored to provide a desired balance of properties such as stiffness, durability, and impact and heat resistance. For valves and threaded applications, LubriOne formulations offer wear resistance, reduced friction and heat build-up, noise and vibration damping, fewer power and maintenance requirements, design flexibility and lower part weight. LubriOne materials are formulated with an internal lubricant to offer a low coefficient of friction and lubricity, as well as wear resistance.

offerings that enable customers to differentiate their product, create brand identity, and provide colour coding. Valves and fittings in the fluid handling industry have traditionally been made of cast iron, brass or PVC. PolyOne’s engineered materials are high- performing polymers that can meet the demands of specialised fluid handling applications, offering lighter weight than metals, good chemical resistance, and targeted physical property performance. These products also support the California Lead Plumbing Law (AB 1953), which states that any product that dispenses or conveys water for human consumption in a California building be ‘lead free’ as defined by the law. In addition, PolyOne’s design assistance and processing support help create a smooth conversion from other materials to a PolyOne engineered compound, even for the most complex applications.

Since 1979, Ritmo SpA has played an important role in the welding of HDPE and other plastic pipes, with new ideas and products designed and manufactured in Italy. The company’s My Log data logging system controls and registers the entire welding process. Its reports certify that welding has been performed according to the parameters set. The data gathered throughout the welding cycles is saved in an internal memory, and may be downloaded and handled on a PC by means of specific software. My Log is supplied in a protective case, and has a wide graphic display and an intuitive control panel designed for ease of use. PolyOne Corporation is a provider of specialised polymer materials, services and solutions for a wide range of fluid handling applications. The company’s Nymax™ nylon formulations, Maxxam™ polyolefin formulations and LubriOne™ lubricated and wear-resistant materials are suitable as metal replacements for valves and fittings. This metal-to-plastic conversion allows customers to reduce the weight of their parts and eliminate secondary operations for greater operational efficiency. The NSF Standard 61 certified and lubricated compounds for fluid handling applications are currently available in North America. PolyOne’s approach pairs customers with a knowledgeable formulator to define solutions that accelerate the design process and get products to market faster. The company provides a broad range of standardised and customised formulations in several resin families, including new pre-coloured

My Log can be used with many machines – not only those produced by Ritmo – so it may be considered an ‘open system’. In the butt welding field, from medium to large ODs, Ritmo has invested in the concept of user-friendliness: highly technological machines that handle the entire cycle by means of an intuitive control panel; with software, entirely developed by Ritmo engineers, that assures smooth and faultless welding. The Ritmo Group also provides technical assistance and information to all its customers. A qualified team of experts is available to assist with technical enquiries.
