NIRON PP-RCT pipes and fittings were installed in 2 elementary schools in the City of New Orleans. After an exhaustive presentation of the electrofusion technique, the contractor selected this option for being an excellent time and money saving option. Diameters ranged from 63mm through 160mm, with several transitions from steel and copper. The system was installed for chilled water, potable hot and cold water. PP-RCT is a complete polypropylene pipe and fitting system manufactured 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.
