SMARTFLEX training for the largest Permatank (double wall steel/fiberglass tanks) factory in South East Asia. Only SMARTFLEX™ Certified Installers can access the welding unit using their specific SMARTCARD that contains an identifiable barcode and the necessary information. NUPI Industrie Italiane regularly trains and reviews certified installers worldwide. SMARTFLEX is the 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 electrofusion welding system typical of the SMARTFLEX system 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.
