NRI’s composites save European underground water lines

During the winter months, district heating systems distribute hot water 266°F (130°C), from European Union power plants to residences and returns cool water 140°F (60° C) to the plants. When the snow melts in spring, these underground the bunkers that hold the pipes are often full of standing water which causes a high level of external corrosion. Read […]
