What are the key considerations when managing expansion in above-ground HDPE pipe installations?

Ensure there is enough space for your pipe to both expand and contract
When ordering pipe, order additional pipe to manage the expansion.
Clear the space for the pipe to move of rocks and objects which could potentially damage the pipe
Use high quality brackets and restrictors
Meet with Advanced Pipe Systems early in your planning process to ensure a smooth outcome
Ensure your installation is done right in the first instance, or risk issues down the track
