Concealed Installation
In concealed installation, for both cold and hot water pipe lines,
it is not necessary to take into account linear expansion. Pipes can be encased or
embedded in walls, concrete and plaster as with other metal pipes
The expansion of pipe due to temperature will not damage the wall
plastering as the linear expansion is prevented by the compressive strain and tensile
stress of concrete and plaster, it will be absorbed through the material itself.
Insulation
Hot Water System
Normally for hot water systems, it may not be
necessary to insulate Vesbo pipes in tropical countries for interior or concealed
installation. This is due to the low thermal conductivity property of Vesbo (0.24 W/mK)
Heat loss will be minimum. However, for application where central boiler is used for
distribution of hot water and the circulation of hot water being continuous, it is
necessary to insulate distribution lines to prevent excessive loss heat and energy
wastage. Because of the low thermal conductivity of Vesbo Pipes, insulation thickness is
greatly reduced. Following is the recommended insulation thickness.

Chilled Water System
For chilled water of temperature less than 10 °C , due to condensation that may take place, insulation is necessary but reduced considerably in thickness as compared to metal pipes. Heat loss for hot water pipe is reduced to a minimum.
Table shows the insulation thickness for Vesbo pipes in cold countries and chilled water systems so as prevent condensation.
