SMARTFLEX fuel piping system

Multilayer HDPE fuel pipework, joined by electrofusion.

SMARTFLEX is a complete underground pipework system for fuels. Each product pipe is PE100 high-density polyethylene with an inner lining that acts as a barrier to hydrocarbons, so the line keeps the toughness of HDPE without the permeation of plain plastic pipe. Joints are made by electrofusion.
