The BLUTOP® range

blutop banner

As the final link in the water cycle before consumption in our homes, distribution pipes play a crucial role in ensuring a reliable supply of high-quality water. BLUTOP® is a dependable, proven solution for small-diameter pipes, eliminating the need to choose between flexibility and corrosion resistance, between competitiveness and durability, and between innovation and tradition.

Product Specification

100% compatible with plastic pipes
blutop sustainability
The BLUTOP® solution was developed in keeping
with the principles of sustainable development and
delivers outstanding environmental performance.
As investment in renewing water supply
infrastructure is declining in relative terms, water
network managers are demanding longer service
lives. Ductile iron components are not prone
to ageing. Their mechanical properties remain
constant over time.

blutop leaktightness icon
Reducing the amount of water lost in leaks from
pipe systems is a major issue. BLUTOP® delivers a
two-pronged solution, as ductile iron components
(including pipes, fittings, valves and accessories)
have an excellent reputation for both leaktightness
and pressure resistance.
Improving leaktightness reduces head losses,
which in turn saves energy.

blutop installation icon
BLUTOP® revolutionises pipe installation and use.
Pipe-laying operations are quicker because pipes
and fittings can be transported by hand and
inserted using a crowbar.
The BLUTOP® pipe range is compatible with
existing plastic pipe networks and their related
connection and maintenance accessories

In accordance with the major European regulatory
requirements, drinking water Certificates have
been obtained for all materials used in the
BLUTOP® range (DUCTAN® coating, epoxy,
elastomers, lubricating paste and repair products).

Potable Water

Saint-Gobain PAM supplies ductile iron pipelines throughout the world, allowing water to be transported from its source to treatment plants and places of consumption. PAM solutions cover the entire water transport cycle :

  • gravity supply ;
  • potable water distribution ;
  • water treatment ;

Saint-Gobain PAM is involved in both the preservation of the 'water' resource (quality and quantity) and its transport in all situations (mechanical stresses, pressure surges, environmental constraints, etc.).
