Many chemical processes involve the storage and transfer of products in pipelines. Often these products can freeze, become extremely viscous, or condense if allowed to cool to ambient temperature. While insulation and an adequate flow rate can sometimes prevent problems during processing, it may not be possible to prevent cool down during extended nonprocessing times. In these cases, heat must be added to the piping and equipment to offset the heat losses. A common way to provide this heat is to install electric or fluid heat tracing along the pipe. A critical component of the heat tracing system is an effective and efficient insulation. This article outlines the factors that need to be considered in choosing the insulation and optimizing tracer design. The selection process involves: choosing the type of insulation that best fits the application; determining the thickness of insulation based on an economic analysis; selecting a weather barrier to help maintain system integrity after installation and extend insulation service life; and matching the heat tracing system to the application.
