Types of Insulations:

1. **Thermal Insulation:**
– Widely known and commonly used insulations that reduce energy consumption.

2. **Cryogenic Insulation:**
– Applied mainly in natural gas networks, and the temperature required for cryogenic insulation sometimes reaches as low as -190 degrees.

3. **Sound Insulation:**
– Primarily used in cases of turbines and power plants with specialized types of sound insulations, such as induced draft and forced draft.

4. **Polyethylene Insulation:**
– Concerns the insulation of underground pipes (for oil, natural gas, etc.).

Applications in the Industry:

– Power generation units
– Boilers
– Electrostatic filters
– Turbines
– Hot air ducts
– Pipelines, etc.

In refineries:

– Pipelines
