New NIRON welding saddle with socket fusion outlet item code NGS. It offers the possibility to carry out polyfusion joining with socket couplers with diameter Ø110-125 on pipelines of large diameter (Ø315). It is therefore possible to intervene on the lines after laying the pipes, a great advantage if a revamping intervention is being carried out on riser columns where you cannot predict the course of the lines and, therefore, the precise position of the outlet to the floor. This allows to avoid carrying out this outlet with a butt fusion socket fitting, speeding up the installation. Working with polyfusion outlets with diameter of Ø110-125 means covering a wide range of floor distribution possibilities in medium-large systems with absolute versatility of installation that involves low costs in terms of time and resources. This item also allows to streamline otherwise highly impacting and costly processes. In fact, it is no longer necessary to carry out the three welds as in the case of installing a socket tee or electrofusion welding for electrofusion branch saddles, but you just need a hole and a single polyfusion weld to obtain the desired outlet. The NIRON system, particularly suitable for use in large buildings and industrial installations, has special characteristics of the raw material that guarantees high mechanical strength and durability, even at high temperatures and pressures. NIRON boasts various installations in large collective buildings such as schools, universities, hospitals, retirement homes, condominiums and industrial plants where savings in terms of costs and energy and safety are of primary importance.
