NULG
Mingxu
Engineered with a high-purity aluminum core and multi-layer insulation system, this piping solution combines the lightweight advantages of aluminum with enhanced thermal resistance and corrosion protection. Compliant with EN 1254-2 standards for metallic piping systems, the NULG pipe ensures reliable performance in both indoor and outdoor installations where temperature control and structural integrity are critical. Its innovative design eliminates condensation issues common in uninsulated piping, making it ideal for climate-controlled environments and temperature-sensitive fluid transport.
The pipe features a 99.5% pure aluminum core engineered for optimal fluid flow and corrosion resistance. Surrounding the aluminum core is a UV-stabilized cross-linked polyethylene (XLPE) insulation layer with a minimum thickness of 3 mm, providing exceptional thermal resistance. An outer jacket of polyvinyl chloride (PVC) adds mechanical protection against impact, abrasion, and environmental exposure, creating a complete system that requires no additional insulation.
Designed to maintain stable fluid temperatures, the NULG pipe achieves a thermal conductivity rating of ≤0.03 W/m·K and operates effectively within a temperature range of -30°C to 70°C. This thermal stability minimizes energy loss in heating applications and prevents condensation in cooling systems, reducing operational costs and maintenance requirements. The insulation system also provides dielectric strength of 10 kV/mm, making the pipe suitable for installations near electrical equipment.
The lightweight design (approximately 2.4 kg/m for 50mm diameter) simplifies handling and reduces installation time compared to steel alternatives. The pipe features precision-machined ends with standardized dimensions, enabling secure connections with compression fittings or flanges. Its flexibility allows for minor directional adjustments during installation without compromising structural integrity, accommodating slight movement in building structures or ground shifts.
In heating, ventilation, and air conditioning systems, the NULG Insulated Aluminum Pipe efficiently transports hot and cold water between boilers, chillers, and distribution points. Its thermal insulation properties reduce energy loss and prevent surface condensation, enhancing system efficiency in commercial buildings and industrial facilities.
The pipe is widely used in industrial settings for transporting temperature-controlled fluids, including glycol mixtures, coolants, and process water. Its corrosion resistance makes it suitable for chemical processing plants, food and beverage facilities, and pharmaceutical manufacturing where purity and reliability are critical.
Utility companies utilize the NULG pipe for distributing hot water in district heating systems and protecting outdoor water mains from freezing temperatures. Its UV resistance and mechanical durability ensure long-term performance in buried and above-ground installations, reducing the need for frequent repairs.
The pipe is rated for a maximum working pressure of 16 bar at ambient temperature (20°C). Derating factors apply for elevated temperatures, with pressure ratings decreasing by approximately 10% for every 10°C increase above 20°C, as specified in the product datasheet.
The multi-layer insulation features a hermetic aluminum foil barrier between the XLPE insulation and PVC jacket, creating a vapor-tight seal that prevents moisture penetration. This barrier, combined with moisture-resistant adhesive layers, ensures long-term thermal performance even in high-humidity environments.
The pipe is designed for use with standard compression fittings, flanged connections, and push-fit connectors compatible with aluminum piping systems. Consult the manufacturer's specifications for recommended fitting types based on application pressure and temperature requirements.
Yes, both the aluminum core (approximately 85% of total weight) and plastic components are fully recyclable. The pipe's construction allows for easy separation of materials during recycling, supporting sustainable waste management practices and reducing environmental impact.
