Italy Rigse (Ruige Si) piping system is composed of five layers extrusion process from production, suitable for cold and hot water, and heating and air conditioning system, double cross-linked polyethylene (PEX-B) located in the innermost and an outermost layer, an adhesive layer and a strong middle oxygen barrier plastic pipes make Rigse pipes and metal pipes have all the great features, rugged, impact, corrosion resistance, anti-aging, in the middle of the aluminum layer can greatly increase the life of the pipeline , increase safety, the most important is that it can completely block the entry of oxygen, the oxygen barrier effect play. -8006 Aluminum, are more solid than any other aluminum alloy, aluminum layer using laser butt welding process, ensuring a uniform aluminum layer thickness, quality and stability. Certification Rigse piping system has been Europe's most prestigious research institute institution: DVGW and Italian plastic Institute (IIP) to solve the lack of a single composite pipe on material properties; for example, metal corrosive, easy to bend, easy to scale Because of the inherent shortcomings such as cross-linked polyethylene and are in line with and, while the liquid will come into contact with crosslinked polyethylene layer, while plastic easy penetration of oxygen, fear of light, easy to aging, such as frequent expansion and contraction after another by the inherent shortcomings bonding and off in the middle aluminum layer. Rigse using the most advanced production lines, all aspects of the production line equipment on the market are made from prestigious companies, to ensure that the thickness of each layer fluctuations are controlled within a minimum tolerance Italy Rigse (Ruige Si) PERT products Features tightness (five pipes) in line with DIN4726 standard ⊙ high temperature high pressure, -10 ℃ -95 ℃, 10bar ⊙PE-Xc pipes easily corroded, materials chemistry, and alternative materials except ⊙EVOH oxygen barrier, its smooth wall and difficult to scale, long life ⊙ uses five pipeline technology, applied particularly rough uneven device environment ⊙ resistant variety of chemicals (please ask for details) ⊙ unique scientific connection, using the slide tight compression type fittings ⊙ Wide range of applications, warm, radiator, water connection ⊙ pure health, can be used for drinking, Italy Rigse (Ruige Si) PPR Pipe Series uses the most advanced technology and the world's most high-quality polypropylene material in Europe, and according to the most stringent international norms quality testing to ensure product stability. Has won the UNI EN ISO 9001: 2000 quality system certification and TUV organization issued n15 100 63838 international certification. Relying on the advantages of having the world's logistics centers in Italy, the company exports more than 80% of its business to the world.
