Pipe insulation serves multiple purposes depending on the system: reducing heat loss from hot pipes, preventing condensation on cold pipes, protecting personnel from contact burns, controlling process temperatures, and preventing freeze damage.
Material selection matters enormously. Elastomeric foam (Armaflex) is ideal for cold applications where vapor control is critical. Fiberglass is appropriate for hot systems. Mineral wool handles high-temperature applications. Cellular glass is used for cryogenic and high-temperature extremes.
Installing the wrong material — or installing the right material incorrectly — defeats the purpose. We select the correct insulation for each system's operating temperature, service conditions, and environment.
