Galvanized iron sheet insulation pipe

Galvanized Iron Sheet Insulation Pipe

Product Overview:
The galvanized iron sheet insulation pipe is a pre-fabricated thermal pipeline designed for transporting hot water, chilled water, or other thermal fluids in HVAC, industrial, and municipal applications. It features an inner steel pipe for fluid transport, a high-efficiency insulation layer, and an outer protective layer made from galvanized iron sheet (GI sheet), offering excellent thermal performance, durability, and corrosion resistance.

Structure Composition:

1. Inner Carrier Pipe:

• Material: Seamless or welded steel pipe (e.g., Q235B, 20#)

• Function: Transports thermal fluids such as hot water or chilled water

2. Insulation Layer:

• Material: Rigid polyurethane foam or rock wool

• Function: Reduces heat loss and maintains fluid temperature

3. Outer Casing:

• Material: Galvanized iron (GI) sheet

• Function: Provides mechanical protection and corrosion resistance, especially in indoor or exposed environments

Key Features:

• Excellent thermal insulation: Maintains temperature stability over long distances

• Corrosion-resistant GI cladding: Protects insulation and extends service life

• Pre-fabricated system: Simplifies on-site installation and reduces labor costs

• Fire-resistant and weatherproof options available

• Customizable lengths, diameters, and insulation thicknesses

Technical Specifications:

• Pipe Diameter: DN25–DN1000 (custom sizes available)

• Insulation Thickness: 30–100 mm

• Insulation Material Density: 60–80 kg/m³ (PU foam)

• Operating Temperature Range: –40°C to +140°C (higher ratings optional)

• Outer GI Sheet Thickness: 0.3–0.8 mm

• Standard Compliance: GB, ASTM, or project-specific standards

Applications:

• Central heating and cooling systems

• Industrial process pipelines

• HVAC piping in commercial buildings

• Indoor and exposed thermal pipeline networks

• Residential hot water supply systems

Advantages:

• Cost-effective thermal pipeline solution

• Lightweight and easy to transport and install

• Smooth galvanized finish offers a neat appearance for visible installations

• Long service life with minimal maintenance

• Versatile use for both above-ground and indoor piping systems
