The SMARTFLEX double wall system diameters 63/75mm and 90/125mm was successfully installed in a Lukoil filling station in Moscow, Russia. SMARTFLEX is a complete multilayer piping system for the transfer of automotive and aviation fuels, biofuels and hazardous fluids. Thanks to an ongoing research and development programme and in conjunction with the major oil companies, the SMARTFLEX piping system has become the leading design system on the market today. SMARTFLEX piping system has been tested for special AVIO fuels and has shown its suitability for marina and airport filling point applications. The problem of rusting, pitting and scaling that commonly leads to the failure of metal pipeline systems is eliminated with the use of this SMARTFLEX multilayer HDPE pipes. The durability, integrity of joints, resistance to corrosion and chemicals and reduced head losses if compared to metal pipes offer great benefits. SMARTFLEX is ideally suited for these kinds of installations thanks to its electrofusion welding system that allows for greater protection and leak-tightness. The welding process is carried out at minimum voltages in compliance with accident prevention standards. The use of barcodes that contain important information about the products allows for initial checks and records as well as for monitoring during the product lifetime ensuring complete traceability and a higher degree of reliability.
