Double Wall Piping

A complete system of single and double wall HDPE pipes already used and approved by major international petroleum companies for the transfer of fuel and hazardous liquids.

SMARTFLEX is a complete multi-layer piping system manufactured by NUPI Industrie Italiane for the transfer of automotive and aviation fuels, biofuels and hazardous fluids. The system has many international and local approvals - UL, EN, IP, Kiwa etc. - and is already used and approved by major international petroleum companies, in response to whose needs it has been conceived, developed and successfully launched into the market.

SMARTFLEX  has a vast range of pipes and fittings including:

  • single-wall lined pipes for both product lines and vent/vapour and filling lines;
  • double-wall lined pipes for more demanding containment and monitoring requirements;
  • a full range of electro-fusion fittings for safe, corrosion-proof joints
  • spigot and riser fittings;
  • mechanical fittings;
  • flexible and electro-fusion entry boots for positive sealing of sumps;
  • leak monitoring systems;
  • HDPE tank sumps and dispenser sumps.
  • Welding units and tooling

All products are available in a wide variety of sizes and configurations making the system suitable to various kinds of installation.

Cutting-edge technology and installation cost-reduction
 
The key materials employed in the production of SMARTFLEX is high-density polyethylene (HDPE-PE100), a material with high durability and working benefits to the user. Moreover, HDPE can be a more cost-effective solution than more traditional materials such as metal. All SMARTFLEX primary piping consists of a multi-layer composite wall lined product pipe that combines the excellent mechanical properties of HDPE with the low permeability and high resistance to hydro-carbons of a new class of polymers used in the lining material and creates a level of hydro-carbon compatibility unattainable by other fuel pipes available on the market today.
