During production, the tubes are subjected to a patented passivation treatment and stabilisation of the inner wall. SMISOL® Gas copper tube has a carbon residue C<0,06 mg/dm2, much lower than that required by EN 1057 which defines a carbon content limit of C≤0,20 mg/dm2.
Tested and guaranteed stabilised polyvinyl resin sheath. The sheath protects against damage from external agents such as building materials (eg. quick-setting cement) and damage caused by impact during the construction site transportation. It allows for underground trenching tube installation, as indicated by UNI 10823: “the coating is obtained by extrusion, in a seamless and continuous manner, externally and internally smooth, with a uniform nominal thickness, with full adhesion to the copper tube external wall along its entire surface to ensure absence of air pockets and prevention from slipping off”.
It is tested in line in order to ensure the required electrical Insulation resistance that, as per UNI 10823, must be equal to or greater than 100 MΩm2.
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.
Electrical insulation resistance: ≥100 MΩm2 (UNI 10823).
