Pipes for domestic gas networks



- Cold drinking water.
- Distribution of liquid and gaseous fuels.

This copper tube is produced according to standard EN 1057, during
production it is sheathed with a special continuous PVC covering with a star-shaped cross-section. The original in-line coating process allows for a malleability that is higher than comparable market alternatives, positioning it at the top of its category. It has proven bacteriostatic properties which make it particularly suitable for drinking water supply, in order to prevent the proliferation of bacteria such as Legionella. The absolute impermeability to gases also makes it suitable for use in the transport of liquid and gaseous fuels. Furthermore, in accordance with EU REgulation 305/2011 for construction products (CPR), SMISOL® Più copper tubes are CE marked.
A further guarantee of compliance with prevailing regulation standards is assured with the achievement of UNI-IGQ Quality certification.

Further details
Internal protection
During manufacture, the tubes are subjected to a patented treatment for passivation and stabilisation of the internal walls, thus assuring absolute compliance to the potability parameters required by European legislation for transported drinking water (European Directive 98/83 and Law Decree 31/01). SMISOL®Più copper tube has a carbon residue C<0,06 mg/dm2, much lower than that required by UNI EN 1057 which defines a carbon content limit of C≤0,20 mg/dm2.
External protection
Tested and guaranteed stabilised polyvinyl resin sheath.
Other specific advantages are given by:
Reduction or elimination of unsightly and unhygienic r stains of dampness on walls.
The star-shaped cross-section of the sheath absorbs small thermal expansions (linear thermal expansion coefficient= 0,00168 mm/m°C).
Protected against impact damage during transport and on-site installation
Sheath characteristics
Sheath material in special stabilised PVC resin.
Star-shaped cross-section.
Minimum sheath thickness: 1,5 mm (under continuous laser gauge control).
Sheath manufactured from high-quality virgin granules.
Excellent resistance to external chemical agents.
Ink marking every meter.
