  • Steam pipes and condensate return pipes that are not insulated are a constant source of heat loss which is easy to remedy. Insulating all heat surfaces is, in most cases, an easy measure to implement. In addition, localised damage to insulation can be readily repaired. Insulation might have been removed or not replaced during operation maintenance or repairs. Removable insulation covers for valves or other installations may be absent.
    Wet or hardened insulation needs to be replaced. The cause of wet insulation can often be found in leaking pipes or tubes. The leaks should be repaired before the insulation is replaced.


  • Increased use of insulating materials.


  • As a baseline, all piping operating at temperatures above 200 °C and diameters of more than 200 mm should be insulated and good condition of this insulation should be checked on a periodic basis ( e.g. prior to turnarounds via IR scans of piping systems). In a ddition, any surfaces that reach temperatures of higher than 50 ºC where there is a risk of staff contact, should be insulated.



  • It can give rapid payback, but time depends on energy price, energy losses and insulation costs.
