Expansion Loop in Steam Piping
Within the header for 150 psig Steam, the temperature within can be in the 370-450 degrees Fahrenheit range in this part of the plant. Steel piping definitely expands in dimension when heated up to that range. This omega-shaped loop is meant to deal with the linear expansion. The curved loops are only seen in the part of the plant that was established in the 1920s and 30s. Today, the same function is addressed by an arrangement of straight piping and elbows assembled into a ‘U’ shape, most always positioned in a horizontal plane above the main run of piping.
