ABN Group’s constant commitment to research, development and innovation of its products has resulted in the obtaining of mechanically and hydraulically improved and competitive sanitation solutions through the development of ovoid pipes. This development was carried out by using injection methodology (Previous Ovalpipe-FEDER INNTERCONECTA 2013 project). However, despite promising results, the ovoid profile of these pipes and especially their development by injection (high investment in molds, production of parts discontinuously, etc.) results in: entry into the long and complex market (need for large investments in manufacturing mainly), high costs and impossibility of making the pipe in a single piece (existence of joints and increased leakage). With the intention of solving these technological challenges and starting from the expertise acquired by ABN, with the participation, as partners, of research organisations, GEAMA and CETIM, with extensive knowledge in the field of hydraulic developments and advanced materials, respectively, the Ovalpipe II project is proposed. It will carry out the development and optimisation of pipes with ovoid profile using extrusion technology, which will allow to take advantage of all the promising results of the previous project, and the additional advantages offered by the use of the extrusion system for obtaining pipes: high continuous production, ease of manufacture of different diameters, improvement of properties by modification of pipe thickness, etc. To achieve this general objective, the Ovalpipe II project will focus on five working lines: 1.Selection of materials, formulations, designs and modellings aimed at achieving improved mechanical, chemical, physical and hydraulic capacity oriented to saving materials, energy and carbon footprint. 2.Design and implementation of extrusion processes for the development of ovoid pipes with improved properties. In the project it will be essential to adapt and optimise the conventional extrusion technique to the development of the pipes under study, as well as the adaptation of satellite systems to obtain this type of pipes. 3.Determination and verification by testing prototypes of the chemical, physical, structural and hydraulic properties of the developed pipes. 4.Pipe scaling and pilot scale verification of new developments. 5.Technical, economic and environmental assessment of new developments. This project responds to the needs raised in the State Program of R & D & I oriented to the challenges of the Society, specifically the RETO 5 of Action on climate change and efficiency in the use of resources and raw materials, aligned with the objectives of Ovalpipe II of development and optimisation of an extrusion methodology for obtaining pipelines with ovoid profile, joining systems and, all focused on high efficiency sanitation networks. In turn, it also responds to Social Challenges 5 and 6 of Europe 2020 IV. Smart, Green and Integrated Transport, and V. Climate Action, Environment, Resource Efficiency and reflectives societies, aligning with Ovalpipe II’s objectives of developing efficient and environmentally sustainable sanitation methodologies and in the partial use of recycled polymeric materials for project developments.
