STRONG, a copper tube specifically designed for use on heavy engineering sites; in fact its special crush-proof coating guarantees protection against any stress that may occur on site before the tube is installed under the floor, preventing impacts, abrasions and contact with particularly aggressive materials. The coating is made in low density, closed cell expanded polyethylene, in compliance with Law 10/91, former Law 373, concerning the design, installation, running and maintenance of thermal plants in buildings designed to control energy consumption. The coating is odourless, non-toxic and made without the use of CFC. It is suitable to be used in plants with operating temperatures ranging from -70°C to +95°C. The coils are individually wrapped in a transparent film giving further protection to the coating during handling and transport. The STRONG copper tube is supplied in 50-metre coils, marked at intervals also indicating the relative meters. The core of the STRONG is formed by the ESENCOR copper tube, which provides excellent protection against corrosion. It is the result of scientific studies and tests that guarantee a considerably lower level of residual carbon than that required by manufacturing standards. |
