ELOFIT fittings and POLIETILENETUBI pipes were installed at Legoland water park in Castelnuovo del Garda. ELOFIT is a High-Density Polyethylene system of electrofusion and spigot fittings and special components for the conveyance of water and gas under pressure. ELOFIT fittings are manufactured by injection moulding of High-Density Polyethylene and achieve the highest standards as regards the resistance to corrosion, stray currents, impact, chemical agents, abrasion, micro-organisms. They have a reliability of more than 50 years. ELOFIT is suitable for the conveyance and distribution of drinking water and alimentary fluids, fuel, and inert gases and for water treatment plants, centralised irrigation and sewage systems, fire protection systems and pipe relining. The ELOFIT system is mostly assembled through the electrofusion process. On the inside, the fitting houses electrical resistors connected to the outside cable terminals. When current moves through them, these resistors generate the heat needed to melt polyethylene. Energy is transmitted directly and exclusively to the surface where pipe and fitting come into contact with each other, producing heat welding. The main feature of ELOFIT fittings is the high quality and reliability of the welding. When it cools down, the connection is even, strong, safe, and reliable.
