Latest Patents

Karl G Dahmen holds a patent for a method of leak detection in heat exchanger tubes and their tube sheet connections. This patent outlines a procedure to test a shutdown steam condenser for tube leakage. The method involves reducing the pressure in the water boxes below atmospheric pressure while keeping the steam casing open to atmospheric pressure. This allows for the detection of air leakage into the boxes, which serves as an indication of tube leakage. The leakage is preferably indicated using a soap bubble test conducted by a workman inside the box. For safety, one of the entrance manholes to the water box can be sealed with a U-tube water seal, which will break automatically in the event of excessive underpressure.
