Sesta piping system is produced by a 5-layer extrusion process, suitable for cold and hot drinking water, as well as heating and air-conditioning systems. Double-layer cross-linked polyethylene (PEX-B) is distributed in the innermost and outermost layers The strong adhesive layer and oxygen barrier layer in the middle make Sesta pipelines have all the excellent characteristics of plastic pipes and metal pipes. The strong, impact-resistant, corrosion-resistant, aging-resistant, aluminum layer in the middle can greatly increase the life of the pipeline and increase safety. The important thing is that it can completely block the entry of oxygen and play an oxygen blocking effect. -8006 aluminum alloy is stronger than any other aluminum alloy. The aluminum layer adopts laser butt welding process to ensure uniform thickness and stable quality of the aluminum layer. Sesta piping systems have been certified by the most prestigious institutes in Europe: DGW and the Italian Institute of Plastics (IIP)
The 8006 composite aluminum tube solves the shortcomings of the characteristics of a single raw material; for example, the inherent shortcomings of metal such as corrosion, bending, and scaling are neutralized due to compliance with cross-linked polyethylene, and the liquid will only contact the cross-link. The polyethylene layer, at the same time, the plastic is easy to oxygen, afraid of light, frequent thermal expansion and contraction and easy to aging and other inherent shortcomings are again neutralized by the aluminum layer bonded in the middle. SESTA adopts the most advanced production line. The equipment of each link of the production line is provided by a well-known company on the market, ensuring that the thickness fluctuation of each layer is controlled within the minimum tolerance.
