Fiberglass Pipe Insulation insulates copper and black iron piping that helps carry domestic hot and cold water, roof drains, PVC piping in plenums, Polypropylene piping, Chill water piping, etc. The pipe insulation comes in 3-foot sticks, with insulation ranging from 1/2″ to 5″ wall thicknesses.
Structure And Materials
Fiberglass insulated steel pipe is usually composed of three layers of composite structure:
1. Working steel pipe
Common materials include Q235B and Q345B spiral welded pipes or seamless welded pipes .
2. Polyurethane rigid foam insulation layer
Closed cell rate ≥ 92%, thermal conductivity ≤ 0.033W/(m·K).
3. Outer sheath
High-density polyethylene (HDPE) is used in conventional environments, with a thickness of ≥ 2mm; FRP outer sheath can be selected for high temperature or corrosive environments, with a thickness of ≥ 3mm.
Performance Characteristics
1. Corrosion resistance: It can effectively resist the corrosion of acid, alkali, salt and other media and the erosion of chemical liquids, and is suitable for various corrosive environments.
2. Antifreeze performance: Below -20℃, the pipe will not freeze after freezing.
3. Lightweight and high strength: Light weight, high strength, easy to transport and install.
4. Thermal insulation performance: The polyurethane insulation layer can effectively reduce heat loss and reduce the heat loss rate.
5. Heat resistance: It can be used for a long time in the temperature range of -40℃~70℃, and the special formula can work normally at a temperature above 200℃.
6. Good hydraulic conditions: The inner wall is smooth, the conveying capacity is strong, it is not easy to scale, and it is not easy to rust.
7. Low maintenance cost: Due to the corrosion resistance, wear resistance and antifreeze properties, the project maintenance cost is low.|
Application Scenarios
Fiberglass insulated steel pipe is widely used in various pipeline systems, including:
• Oil pipeline
• Chemical pipeline
• Power pipeline
• Pharmaceutical pipeline
• Paper pulp pipeline
