What is a swing joint primarily used for in irrigation systems?

A swing joint is primarily used in irrigation systems as a flexible connection between a sprinkler head and the pipe system. The design of a swing joint allows for movement in multiple directions, which helps to prevent breakage or damage to the piping and the sprinkler head. This flexibility is particularly beneficial in areas where the ground may shift or where there are changes in elevation, as it can accommodate physical movements without putting undue stress on the components.

By enabling a secure yet adaptable link, swing joints protect the integrity of the irrigation system and ensure that the sprinkler heads maintain optimal positions for effective water distribution. This is essential for achieving uniform coverage and preventing issues such as malfunctioning or misaligned sprinklers.
