HDPE pipe’s typical operating temperature range is from 40oF ( 400C) to 140oF (60oC) although some products may be pressure rated for service as high as 180oF (82oC). Since water freezes below 32oF (00C) the practical lower temperature limit for water is 32oF (0oC). Consult with the pipe producer for information on appliions.
