Pressure-based fluid corrosion/erosion protection apparatus and associated methods

摘要

The interior of a vessel containing pressurized fluid is protected against undesirable chemical corrosion and/or mechanical erosion caused by the fluid due, for example, to changes in the chemistry of the fluid, by an imperforate, chemically corrodable tube projecting into the interior of the vessel and having a closed inner end. A chemical corrosion through-opening in any portion of the tube permits pressurized fluid to enter and pressurize the tube interior, with fluid pressure within the tube being utilized to automatically generate a corrosion/erosion detection signal indicative of an undesirably high fluid chemical corrosivity level within the vessel.
