What is the minimum spacing requirement for hangers determined by?

The minimum spacing requirement for hangers is determined by considerations of pipe size and material. Different types of pipes, such as metal or plastic, have distinct characteristics that affect how they are supported. For instance, larger diameter pipes require more substantial spacing between hangers to distribute weight appropriately and prevent sagging, while the material of the pipe can influence its thermal expansion characteristics and overall strength.

Using standards based on both size and material ensures that sufficient support is provided to maintain the integrity of the piping system throughout its operational life, mitigating the risks of damage or failure. This approach ensures that the installation adheres to safety guidelines, avoiding excessive stress on joints and connections, which can ultimately lead to leaks or catastrophic failures if not properly considered.
