Pipes are more prone to corrosion when they are laid directly on the ground or other unclean surfaces. Corrosion can begin eating away at the pipe's metal if having any moisture or microbes present. That's why it's important to elevate pipes above any standing water or unclean ground to reduce the risk of corrosion. Pipes can be protected from galvanic corrosion by being raised above any nearby dissimilar metals. For instance carbon steel pipes supported by stainless beams may experience electron theft from the stainless surfaces.
