For internal systems of distribution of hot and cold water in buildings, for systems of floor and central heating, ventilation.
Polypropylene pipe reinforced with fiberglass filling is considered one of the best among other analogues, due to the presence of walls with a solid and monolithic structure, a smaller by 3/4 linear thermal expansion, no need for a cleaning operation before welding and a significant increase in pipeline rigidity.
