With the addition of propper chemical substances to the PP raw material, the product becomes non-flammable. Thus, in case of fire, its spread and maintenance through the drainage system are prevented. According to the standard DIN 4102, PP has been classified in ''not easily flammable materials'' (class B1).
Due to their smooth surface, PP pipesnot not only have great resistance to abrasion, but also prevent the accretion of various substances (dirt, grease, salts, microbes), thus their erosion is avoided. Moreover, they exhibit high resistance to caustic solutions and detergents, which often flow within the drainage systems.
PP pipes can absorb the expansions, contractions and vibrations in buildings. In case of an earthquake, the elastic lip seals can absorb the seismic energy, so that the appearance of cracks and fractures in the pipes and fittings is avoided.
PP is 100 % recyclable material. It can be recycled, burned or burried in the ground without charging the environment, and, according to Greenpeace, is classified in ''healthy'' materials.
PP pipes have higher strength to hydraulic pressure and higher impact resistance, even at low temperatures, compared to pipes made of other
CHARACTERISTICS OF PP PIPES AND FITTINGS
The PP pipes and fittings for building installations meet the requirements of the European standard EN 1451 (class B). The PP products are suitable for usage inside buildings (homes,hospitals,professional and industrial constructions etc.) for drainage networks, air ducts, and hot water installations (kitchen, laboratories etc.)
The color of PP pipes and fittings is grey (RAL 7037).
