INTRODUCTION
Introduction
• Insulation: Insulation is defined as those materials or combinations of materials
which retard the flow of heat energy.
• Insulation Service: Insulation material that is applied on vessels, piping,
equipment etc. to prevent heat loss or heat gain.

PURPOSE
Purpose of Insulation
• Reduces over-all energy consumption.
• Offers better process control by maintaining process
temperature.
• Prevents corrosion by keeping the exposed surface of a
refrigerated system above dew point.
• Provides fire protection to equipment.
• Absorbs vibration.
