The SMARTFLEX system was successfully installed in a filling station in Dubrovnik airport, Croatia. 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. The photos show the welding process and the pressure test. All done with a push of a button with our SMARTFLEX welding machine. That’s a quick and safe installation with a full track record. SMARTFLEX piping system has been tested for special AVIO fuels and has shown its suitability for marina and airport filling point applications. SMARTFLEX has been qualified by major companies for airport applications and has been approved for marina applications as well. The use of coil pipe allows for longer runs, which is ideal for situations where the supply is some distance from the delivery point like airports and heliports. Corrosion and deterioration of underground piping systems can cause serious and costly problems at marina filling points. SMARTFLEX multi-layer HDPE piping can avoid these problems thanks to its durability, integrity of joints, resistance to corrosion and chemicals and reduced head losses if compared to metal pipes. The rusting, pitting and scaling that commonly lead to the failure of metal pipeline systems are eliminated with the use of this multilayer HDPE pipe. 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.
