High-quality polyurethane-foam tubing designed for insulating central heating and domestic-water pipelines. This tubing is resistant in temperatures ranging from -50°C to 135°C, providing excellent protection and low heat transfer. The rigid construction ensures durability and prevents damage to pipes. Additionally, the tubing boasts a high level of chemical resistance, making it suitable for various applications. Our rigid polyurethane spray polyethylene wrapped prefabricated direct-buried insulation pipe utilizes advanced technology to enhance foam density uniformity and insulation layer thickness consistency. This innovative design not only saves materials but also reduces labor costs, making it a cost-effective solution for transporting hot water up to 140°C.
