NUPI polyethylene pipes diameter 500 PN 10 were installed in Piacenza, Italy, for a city water pipeline. POLIETILENETUBI piping range mainly includes NADIR PE 100 and NUPIGAS pipes. NADIR PE 100 pipes comply with the requirements for the distribution of fluids under pressure and is suitable for the transport of water for human consumption. One of the most reet and mosrt important innovations in the PE piping range is the ​ new generation NADIRPlus PE 100-RC high density polyethylene pipe for the distribution of fluids under pressure and fuel gas. A big step forward in the resistance to slow crack growth that was made possible by the latest generation of high density PE100, developed specifically to allow the use of faster and cheaper technical installations such as:

• Installations without trenches or without sand bed (with or without reuse of debris)
• Relining installations (renewal and/or replacement of old distribution networks)

These new techniques require the use of materials that are more and more resistant: NADIRPlus is the answer! NADIRPlus piping range includes NADIRPlus Fluidi and NADIRPlus Gas. NADIRPlus Fluidi and NADIRPlus Gas pipes comply meet the requirements out polyethylene pipes for installations with alternative installation methods. Moreover, they have a high resistance to slow crack growth and point loads, as they are entirely produced with raw material PE100 RC. Apart from great technical and economic advantages, they ensure great reliability and operating life, even in heavy duty installations.
