Тръби с единична стена
SMARTFLEX single wall pipes for the transport of petroleum products, alcohols, alcohol-gasoline mixtures and bio fuels.
A primary pipe is the pipe that carries fuel.
When primary pipe is used without a secondary pipe it is called a SINGLE WALL pipe.
Primary pipe is a multilayer pipe manufactured through a production process called “co-extrusion” (contemporary extrusion of various layers of pipe comprised of different materials). It combines the excellent mechanical properties of HDPE (High Density Polyethylene) and the low permeability and high chemical resistance of an inner and/or outer layer made of a polymeric material specifically suited to the application.
This inner layer guarantees the following:
•A barrier impermeable to fuels
•Excellent resistance to wearing
•High resistance to long-term pressure
•Limited head loss

Тръби с двойна стена
SMARTFLEX double wall pipes for the transport of fuels, alcohols, alcohol-gasoline mixtures and
bio fuels.
A DOUBLE WALL pipe is a primary pipe encapsulated by a secondary pipe.
In SMARTFLEX double wall pipes, the secondary pipe is not just a containment barrier but it is
a real high-density polyethylene pipe capable of sustaining the pressure or pressure drop of an
automated monitoring system. This external pipe is also available with an inner barrier layer as
requested by standards (e.g. UL) and by customers’ specific requests.
The advantages are as follows:
• Excellent chemical resistance to alcohols
