Polyurethane Foam Insulated FRP Pipe

Polyurethane Foam Insulated Frp Pipe is designed for applications of pumped condensatechill water and hot water.

Thermal conductivity of FRP polyurethane insulated pipe is 0.355W/(m.k), and that of hard polyurethane insulation layer is 0.0275/(m.k). It has good heat insulation and preservation performance. Temperature decrease is less than 0.5℃ per kilometer. Its insulation performance is over four times as much as that of other insulation materials.
