Why Is Insulation Important In Steam System Therma

Why Is Insulation Important In Steam System Therma

A proactive insulation-management program is critical to overall steam system thermal-cycle efficiency. Furthermore, because steam systems operate above 212°F (100°C) and as high as 1200°F (649°C), the negative effects of uninsulated components can be dramatic and are unacceptable in today's industrial steam system operation.
