• Low density closed cell polyethylene liner.
• Helically wound spacers
• Air gap: 5 mm min.
• Excellent resistance to external chemical agents.
• Ink marking every meter.
• Not flammable Class 1
During production, the tubes are subjected to a patented passivation treatment and stabilisation of the inner wall. SMISOL® Tekgas copper tube has a carbon residue C<0,06 mg/dm2, much lower than that required by EN 1057 which defines a carbon content C≤0,20 mg/dm2.
The low density closed cell polyethylene 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 complies with reg. EEC/EU 2037/2000 and has class 1 fire resistance complaint to Italian Min. Decree 26/06/84.
With reference to tool-assisted bending procedures, it should be noted that the proper dies and counter dies may differ significantly depending on the make and model of the tube-bender in use.
