Pipe insulation

Pipes carrying hot media are insulated to minimise unintentional heat loss. Heat loss will cool the media while heating the room in which the pipe is located. Both are undesirable.

Considerations to take when insulating pipes are pipe type, the pumped media and the surrounding environment.

Pipes carrying hot media are insulated to minimise unintentional heat loss. Heat loss will cool the media while heating the room in which the pipe is located. Both are undesirable.

Pipes carrying cold media and placed in heated rooms are insulated so as not to heat the media and to prevent condensation on the pipe. The insulation insures that the external surface temperature on the insulation is higher than the room’s dew point temperature. The insulation must be finished with a vapour-proof membrane such as aluminium foil or plastic. This is to ensure that room humidity does not penetrate the insulation and condense.

If a pipe is constructed in a flammable material, insulation can protect it against fire so it can remain functional during a fire. This is especially relevant if a plastic pipe supplies fire protection systems further down the line.
