VALSIR
1. HDPEThe basic characteristics of the raw materials employed, and the transformation technology allow us to create pipes and fittings with elevated characteristics both in terms of technology and quality:• Extremely rapid and simple to install.• Excellent compatibility with most chemical substances normally found in waste water, does not come under attack by micro-organisms.• Thanks to the extremely smooth internal surfaces pressure losses are reduced to a minimum; they also guarantee the absence of deposits or build-up of bacterial flora.• Absence of problems caused by stray currents.• Suited to freezing temperatures (-40°C) and can be used for the hot water discharged from washing machines and dishwashers.• It adapts to bad weather; the carbon black contained in it avoids the oxidation process caused by U.V. rays thus allowing it be installed outdoors.• They are not prone to condensate formation thanks to the low heat conductivity.• They offer good dimensional stability (greater than the values established by the Standard UNI 7615 and DIN 8075) and they also meet the European Standard EN 1519.• The seals on the expansion sockets and the push-fit sockets are made with a special elastomer compound that guarantees a working life of over 50 years.• Availability of a vast range of special pieces that provide flexibility in design and installation.
2. PP Waste Pipe Push-fit flame retardant polypropylene waste and drainage system. Valsir pipes and fittings in flame-retardant polypropylene are produced with UV stabilized grey (RAL 7037) homo-polymer polypropylene. They are smooth, shiny and free of irregularities that would compromise the functional aspect. They meet the requirements of the Standard UNI EN 1451 and can be used inside buildings for civil and industrial use and in particular for the following applications:• waste pipes for the drainage of domestic waste water (low and high temperatures);• ventilation pipes connected to the waste system;• drainage of rainwater inside the building structure.Characteristics• Easy and fast installation.• Excellent corrosion resistance.• No welding or gluing operations required.• Installation does not require the use of special tools.• Good resistance to high temperatures (up to 95°C continuous).
