However, freezing incidents can occur when the tem-. perature remains above 20 degrees F. Pipes exposed to cold air. (especially flowing air, as on a windy day) because of cracks in. an outside wall or lack of insulation are vulnerable to freezing. at temperatures above the threshold. However, the 20 degrees.
HDPE pipeâs typical operating temperature range is from -40 oF (-40 0C) to. 140 oF (60 oC) although some products may be pressure rated for service as high as 180 oF (82 oC). Since. water freezes below 32 oF (0 0C) the practical lower temperature limit for water is 32 oF (0 oC).
