In steam demanding industries, the steam generated is normally locally reduced at the points of consumption. There are several reasons why steam pressure is reduced at points of consumption, such as: the reduction of costs when installing smaller diameter pipes, accessories and valves; or also on many occasions, the steam consuming equipment does not tolerate high pressures or simply must work at a fixed pressure which is below the steam generation pressure. We all know that if we reduce the steam passage section, its pressure decreases at the same time that its speed increases. The most basic way to reduce pressure is to install a manual seat valve in a partially closed fixed position, or insert an orifice plate to reduce the cross section. However, if we use any of these methods to reduce the pressure, any fluctuation in the steam flow upstream (before the reduction of the section) will be reflected downstream (after the reduction).
