    How To Deal With Thermal Pipe Expansion and PE100

    The rate of thermal expansion usually depends on three key factors: The pipe material – different materials expand at different rates. So different types of plastic pipe e.g. PP, PVC, PE etc and different types of metal pipe e.g. HDPE, copper, iron will have
