Pipeline insulation involves covering pipe surfaces with insulating materials to reduce heat loss/prevent cooling loss, avoid surface condensation or freezing, improve energy efficiency, and ensure system safety and stability.

· Energy Conservation: Minimizes cooling loss during transportation

· Freeze Protection: Prevents freezing in low-temperature pipelines or media solidification

· Condensation Prevention: Eliminates surface condensation in high-temperature environments

A complete pipeline insulation system typically comprises the following layers (from inner to outer):

1. Pipe Surface: Cleaning, rust removal, and anti-corrosion treatment

2. Insulation Layer: Primary insulating material (e.g., rock wool, rubber-plastic foam)

3. Vapor Barrier (Optional): Aluminum foil, PVC film (prevents moisture ingress)

4. Protective Jacket: Metal cladding (aluminum/galvanized steel) or PVC casing(protects against mechanical damage and water penetration)
