Pre-Insulated Copper Round Pipe 15mm-28mm, -40°C~150°C, Frost
Protection Systems
pre-insulated copper round pipes (15mm–28mm OD) are engineered for frost protection and
temperature-critical fluid transfer systems. Designed to operate
seamlessly in extreme temperatures from **-40°C to 150°C**, these
pipes feature a durable insulation layer that minimizes thermal
loss, prevents freezing, and ensures energy efficiency. Ideal for
outdoor HVAC, refrigeration, and industrial cooling applications,
they combine the superior conductivity of copper with advanced
insulation technology for reliable performance in harsh climates.

3. Competitive Advantages
① Thermal Efficiency
Multi-layer insulation reduces heat loss by up to 80%, cutting
energy costs in refrigeration and heating systems.
② Extreme Climate Resilience
Withstands freeze-thaw cycles, UV exposure, and moisture ingress,
ensuring longevity in sub-zero or tropical environments.
③ Customizable Solutions
Choose insulation thickness (10mm–25mm), jacket materials (PVC,
aluminum, or stainless steel), and pre-fabricated bends.
④ Rapid Installation
Pre-insulated design eliminates on-site lagging, reducing labor
time by 50% compared to traditional systems.
⑤ Global Compliance
Certified for EU Pressure Equipment Directive (PED) and ASHRAE
standards, ensuring hassle-free import approvals.
4. Key Applications
- Snow-Melting Systems: Insulated pipes for radiant heating in driveways, airport
runways, and stadiums.
- Industrial Refrigeration: Frost-resistant lines for cold storage warehouses, food
processing plants, and breweries.
