Extrusion International 5-2023

65 Extrusion International 5/2023 PIPE EXTRUSION commitment to R&D&I in the water transport sector, one of the bases of the company's development. This drives the creation of better solutions to help combat one of the biggest problems in today's society, water scarcity. With this, it joins other services and products of the company that are committed to the reinvention of pipe- line networks, generating greater value, reducing con - sumption and preserving the environment. Examples of this are the TOM ® PVC-O pipes that have reached the largest diameters on the market (up to DN1200 mm) in order to take advantage of the benefits of the ma - terial in the widest possible range of piping networks, the ecoFITTOM ® fittings (the first to be manufactured entirely in oriented PVC) and digital tools such as TOM Calculation that facilitate the performance of all the mechanical calculations necessary for the installation of TOM ® pipes and thus ensure the optimal performance of the water network. Molecor https://molecor.com/en Innovative Die-Heads Desing for Multilayer Plastic Pipes with Inner Layer in PA or PVDF for Chemical and Gaseous Material Transport Tecnomatic, a leading Italian company in the field of extrusion technologies, has recently introduced new die-heads for multilayer plastic pipes with inner layer in PA for hydrogen transport or inner protective layers in PVDF. The new die-heads are the result of the company's new R&I team's efforts to develop innovative solutions that meet the growing demand for safe and reliable transport of hydrogen and other chemical products. H ydrogen is increasingly seen as a clean and efficient energy carrier that can contribute to the reduction of carbon emissions and mitigating climate change. However, the hydrogen transportation poses signifi - cant challenges, as it requires special materials and tech - nologies that can ensure its safe handling and delivery. Tecnomatic's new die-heads for multilayer plastic pipes with inner layer in PA are specifically designed to face these challenges. The use of PAs (polyamides) as an inner layer provides high resistance to hydrogen permeation and excellent mechanical properties. PA is a thermoplastic material that has high tensile strength, high elastic modulus, and excellent impact resistance. It is also resistant to many chemicals, including hydrocarbons and alcohols, mak - ing it suitable for use in the transport of fuels and other chemical products. The outer layers of themultilayer pipes aremade of PE, while an inner layer of PVDF (polyvinylidene fluoride), a highly resistant and chemically inert material provides excellent protection against corrosion and chemical attack. PVDF is widely used in the chemical process in- dustry for handling harsh and unique liquids to gaseous products including sulfuric, nitric, and hydrochloric acid, as well as compounds such as halogenated, aliphatic, and aromatic solvents. It is also used for handling natu- ral and refined products, oils, and combustible fuels. Tecnomatic's die-heads are designed with a meticulous attention to detail, considering not just the mechani - cal performance, but also the specific characteristics of the polymers being processed. For polyamide (PA) and polyvinylidene fluoride (PVDF), Tecnomatic uses materi - als and treatments that are specifically tailored to meet the unique demands of these materials. This ensures that the die-heads can achieve optimal processing efficiency while minimizing any potential material degradation. TECNOMATIC S.r.l. Via Emilia, 4, 24052 Azzano S.
