DH Pipe production lines
The threat of global warming has been recognised in several countries. The price of energy is rising and energy is also needed to cover the peaks in energy consumption. Under difficult circumstances, during the severest frost, heavily loaded pipes may even burst. Installing Uponor district heating pipes minimizes heat loss along the pipeline.
