Protection and insulating tubes

* Required field

  • Description
  • Properties
  • Technical data


These tubes are manufactured in silicone foam combined with a glass fiber hose in the inner part.

The external silicone foam ensures the thermal and mechanical insulation while the glass fiber hose facilitate the assembly on tubes usually containing high temperature fluids. The thickness of silicone foam guarantees the thermal insulation and within certain limits and conditions protects the inner tubes against impacts and shocks.

Typical application are those where there are dangerously hot, cold or fragile pipes which could get touched or broken for example during maintenance operations.
