What additional measure is critical for piping installations that may experience condensation?

In the context of piping installations that may experience condensation, sloping the piping is crucial. When pipes are sloped, it facilitates proper drainage of any condensate that may form due to temperature differences. This is particularly important in systems where moisture can condense on the interior surfaces of pipes, creating the risk of water accumulation, which could lead to corrosion, pipe failure, or other operational issues.

Sloping the pipes also helps in draining any liquids, thus preventing the buildup of water that could freeze, expand, and cause further damage during cold conditions. Proper slope typically ensures that condensate flows to drain points or low points in the piping system, maintaining the integrity and functionality of the installation.

Insulating piping can indeed help reduce condensation by limiting the temperature variation, but it doesn't address the accumulation of moisture in the same proactive way that sloping does. Painting and burying might have their purposes in certain contexts, but they are not fundamental measures specifically addressing the challenges of condensation management in piping installations.
