What Is Thermal Insulation Aluminium Coil for Pipeline?

The Wide Application of Thermal Insulation Aluminium Coil for Pipeline in Power Plants  

Upon entering a power plant, the first thing that catches the eye is the variety of pipelines wrapped in thermal insulation aluminium coils. From thermal pipelines and fan ducts to air conditioning conduits, these aluminium coils are ubiquitous. They encase insulation wool, presenting a neat, smooth, and glossy appearance. Thermal pipelines are particularly abundant in power plants, crisscrossing through turbine halls and boiler rooms, with a combined length stretching up to tens of kilometers.  

In power plant equipment, large-area aluminium coils are also used to cover critical machinery, such as electrostatic precipitators, induced draft fans, steam turbines, feedwater pumps, deaerators, and high/low-pressure heaters. These components are layered with rock wool and finished with a thin outer shell of aluminium coil. Thus, thermal insulation aluminium coils are extensively applied—wherever there is equipment or piping, these coils are present.  

How to Match 1060 and 3003 Aluminium Coils to Your Needs?  

Different scenarios call for tailored aluminium coil types:  

– 1060 Pure Aluminium Coil: Ideal for room-temperature or low-temperature environments, such as air conditioning refrigerant pipes and standard steam pipelines. Its high ductility allows for easy wrapping around complex curves.  

– 3003 Alloy Aluminium Coil: Better suited for high-temperature or humid conditions, such as coastal power plants or chemical pipelines. The alloy composition enhances corrosion resistance and extends service life.  

– Surface Treatments: Embossed aluminium coils improve grip for outdoor anti-slip requirements, while polyester-coated variants enhance weather resistance and reduce maintenance frequency.  

How to Efficiently Install Thermal Insulation Aluminium Coils for Pipelines?  

Installation quality directly impacts insulation performance:  

– Pre-treatment: Clean pipeline surfaces to remove oil stains and rust, ensuring tight adhesion between the aluminium coil and insulation wool.  

– Seam Handling: Use an overlapping method with rivet fixation to prevent thermal bridging. Apply sealant to joints for moisture resistance.  

– Custom Shapes: For elbows, tees, and other irregular parts, pre-fabricated shaped coils minimize on-site cutting waste.  

Practical Tips to Extend Aluminium Coil Lifespan  

Routine maintenance reduces long-term costs:  

– Regular Inspections: Check for surface damage or detachment, especially at seams and high-impact zones.  

– Waterproofing: Ensure no water accumulates on the outer layer to prevent insulation wool from clumping due to moisture.  

– Mechanical Protection: Install guardrails in high-traffic areas to minimize physical impacts that could deform the coils.
