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.
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 material in special stabilised PVC resin.
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.
