Where should a steam trap be installed in relation to its piping system?

A steam trap should be installed at the lowest point in the piping system because its primary function is to remove condensate (the liquid formed when steam cools) along with any air or non-condensable gases. By positioning the steam trap at the lowest point, gravity aids in the efficient drainage of condensate, preventing water pockets that can lead to inefficiencies and potential system damage.

When the steam trap is located at the lowest point, it ensures that condensate can quickly and effectively drain away, maintaining a proper flow of steam throughout the system. This leads to better heat transfer, reduced energy losses, and a longer lifespan for equipment by preventing issues such as water hammer or corrosion in the steam lines.

Other positions for the steam trap, such as the highest point, coldest point, or hottest point, would not facilitate the efficient flow of condensate and could result in operational issues. For example, the highest point would likely trap condensate in the line, while the coldest point might not promote effective drainage due to temperature differences.
