Insulation of Steam Lines

Insulation can typically reduce energy losses and help ensure proper steam pressure at plant equipment. The application of insulation can lead to significant energy cost savings with relatively short payback periods. The improvement of existing insulation can often lead to further savings. This measure can consist of applying more or better insulating material.

Crucial factors in choosing insulating material include: low thermal conductivity, dimensional stability under temperature change, resistance to water absorption, resistance to combustion, tolerance of large temperature variations and system vibration, and compressive strength – where insulation is load bearing.
