Galvanized pipe insulation is a pipeline system consisting of an inner steel pipe, a polyurethane insulation layer and an outer sheath. It is mainly used in the fields of liquid and gas transmission pipelines, central heating networks, municipal construction projects, etc. Its core structure consists of three layers: an inner steel pipe, a polyurethane insulation layer and an outer sheath.
Structural Composition
1. Inner steel pipe
Usually Q235B carbon steel or seamless steel pipe
2. Polyurethane insulation layer
High-density rigid polyurethane foam, density ≥50kg/m³, closed cell rate ≥90%, thermal conductivity ≤0.033W/(m·K), thickness 50-80mm.
3. Outer sheath
Generally galvanized iron sheet, thickness ≥0.5mm, with UV resistance, wind pressure resistance and corrosion resistance, and can be upgraded to aluminum sheet in special environments.
Performance Characteristics
1. Insulation performance: The polyurethane insulation layer has good insulation performance, which can effectively reduce heat loss and energy consumption.
2. Compressive strength: The combination of the inner steel pipe and the insulation layer enables the pipeline to withstand higher pressure and is suitable for various working conditions.
3. Corrosion resistance: The outer sheath is made of galvanized iron or aluminum, which has excellent corrosion resistance and is suitable for various environments.
4. Convenient construction: It is suitable for complex terrains such as viaducts and pipe corridors, without excavating the ground, and has high construction efficiency.
Application Scenarios
Galvanized pipe insulation is widely used in municipal heating trunk pipelines, industrial steam transportation, high-temperature hot water pipe networks and other fields. Its stable thermal insulation performance and compressive strength make it perform well in various projects.
