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.
