PE Pipe Re-rounding

Re-rounding is the term used to re-shape a deformed pipe prior to a patch repair or installation. On occasions, PE (polyethylene) pipe can lose its “ovality” due to time stored or being stored on a coil. A re-rounding tool is recommended to be used to return the pipe back to a circular shape. Tapping bands are NOT designed to re-shape pipe and should not be used for this purpose otherwise they could fail. Contractors are encouraged to use the appropriate re-rounding tool at all times to ensure that installations are carried out according to the utilities and manufacturers requirements.
