NIRON pipes and fittings were selected for the chilled water piping system for the expansion project of Weather Tech plant. The scale and difficulty of this installation was quite high as the piping was installed more than 50 feet above ground. NIRON's electrofusion system made the job much easier than what the installers would have had if they had used butt fusion fittings. NIRON is a complete polypropylene pipe and fitting system for the distribution of hot and cold water in plumbing and air conditioning systems, for the conveyance of drinking water and alimentary fluids, for installations in industrial plants and for the transport of compressed air and chemical substances. The pipes and fittings that compose the NIRON range are produced using random copolymer polypropylene PP-RCT, a plastic material with a special molecular structure ensuring high mechanical resistance and duration, even at high temperatures and pressures. The properties and other features of the various components make the NIRON system a great alternative to traditional material used in plumbing installations.
