NIRON OB PIPE WITH OXYGEN BARRIER

NUPI Industrie Italiane produces PPR and PP-RCT systems for the distribution of hot and cold water in sanitary and air conditioning systems. The pipes and fittings that make up these systems are made with random copolymer polypropylene, a plastic material with a special molecular structure that ensures high mechanical strength and long operating life. NIRON OB pipe completes the range of the NIRON System by offering the oxygen barrier pipe solution for all those applications where this feature is required. NIRON OB pipe is a multilayer pipe composed of a layer of grey Polypropylene type 4 PP-RCT of the Beta type, a layer of PP-RCT with fiberglass, a layer of glue and an external layer of blue EVOH. NIRON OB pipe has all the characteristics of a PP-RCT SDR 11 pipe (SDR 7,4 for smaller DNs) with the addition of a 0,4 mm layer of external EVOH which offers an efficient barrier to oxygen through the pipe wall. NIRON OB pipe can be welded reliably with the fittings of the NIRON range, both of socket and electrofusion type. The welding operation is preceded by the complete removal of the EVOH layer and the underlying glue layer. The difference in colors makes this easy. EVOH is blue and glue is white so it is easy to identify the grey layer of the pipe to be welded. NIRON OB pipe complies with the performance requirements of EN ISO 14874, DIN 8077 and ASTM 2389 Standards. The grey PP-RCT BETA material is a guarantee of improved resistance performance to NaHClO-based treatments and is suitable for the transport of drinking water. The new NIRON Beta pipe and fitting system is particularly suitable for use in large buildings thanks to the special characteristics of the raw material used, which guarantees high mechanical strength and durability, even at high temperatures and pressures. For over 45 years, NUPI Industrie Italiane has been supplying pipe and fitting systems for the plumbing, industrial, gas, irrigation, heating and oil, chemical and petrochemical markets. NUPI is able to satisfy any installation need, thanks to the creation of special parts specially made upon customer's request.
