Strato®
Polyethylene multilayer with copper core
Copper and polyethylene composite pipe for drinking water and radiator heating. Complies with UNI 11342 and D.M. 174/04, with closed-cell PE foam insulation (Law 10/91 - Presidential Decree 412/93). Lightweight, flexible, bacteriostatic, with low internal roughness. Compatible with EN 1254-8 fittings. Easy to install, fold and splice.
Flexibility and workability
Strato can be bent by hand even with small bending radii. It has no memory effect and stably retains the acquired shape, facilitating installation even in complex spaces.
Hygiene and bacteriostaticity
Totally hygienic, counteracts bacterial growth. Complies with Ministerial Decree 174/04: drinking water comes into contact only with the inner copper surface, ensuring the absence of odor and taste.
bacteriostaticity
Absence of welds
The inner copper tube is obtained by a continuous drawing process. Unlike traditional multilayers, it has no longitudinal joints of the metal layer, eliminating potential weak points in the structure.
Low coefficient of linear thermal expansion
Thanks to the metal core, Strato has extremely low thermal expansion compared to plastic pipes, ensuring high dimensional stability even when the temperature of the transported fluid changes.
Low pressure drop
Extremely low internal roughness (about 1.5 μm versus 7 μm in conventional multilayers) allows for lower pressure drops and reduced tendency to scale and scale deposits.
Total impermeability and 100% oxygen barrier
The metal core makes the tube completely gas-tight. The risk of contamination between inside and outside is eliminated and, in heating systems, the presence of oxygen that can cause corrosion to boilers, circulators, and metal components is avoided.
Key Features
Strato represents the evolution of pipes for transporting drinking water and radiator heating. A product that combines the lightness and ease of installation of traditional multilayer with the unique performance of copper pipe in terms of pressure and high temperature resistance, hygiene and bacteriostaticity, low pressure drop and reduced internal roughness. Strato is manufactured according to UNI 11342: "Seamless composite pipes of copper and polyethylene for fluid adduction," is obtained by co-extruding a specific reduced-thickness copper pipe with an indissoluble polyethylene layer. It is then insulated externally with a closed-cell polyethylene foam insulation coating that complies with Law 10/91, implementing decree Presidential Decree 412/93 and subsequent updates. The quality of the raw material used and the characteristics of the coating, make the product particularly suitable for potable water distribution (in accordance with Ministerial Decree 174/04) and high-temperature radiator heating systems. Ease of installation and bending, no memory effect, light weight, excellent value for money, wide choice of fittings to match, reliability and safety make Strato the truly innovative solution among the latest generation of plumbing pipes.
Junction technology
Strato is compatible with all fittings manufactured according to EN 1254-8 normally used with multilayer piping. The peculiarity of Strato is that it offers an "open" solution and thus is not bound to any specific fitting. Different combinations are available, compatible with the most important brands of fittings on the market, including full-pass fittings. The latter solution makes it possible to adopt smaller pipe sections, saving both in terms of pipe cost and masonry work. Different types of mechanical fittings can be used (press-fit, quick-connect, compression).
