The National Board of Boiler and Pressure Vessel Inspectors

Pulling A Vacuum. When boilers are designed to operate at very high pressures, they are not designed to operate under even the slightest vacuum. A potential vacuum is created when a boiler is shut down. As the unit cools, the steam condenses and water level drops, which allows the pressure to drop.

Why vacuum may be lost or not maintained in steam turbine

Aug 04, 2017· The condenser cannot stand the steam pressure, the condenser tubes may leak from excessive temperature. Excessive pressure will also damage the shell, the exhaust and the low-pressure parts of the turbine. Identifying leaks: First, find the leak by passing a flame over the suspected part while the condenser is under vacuum.

Find Leaking Tubes Quickly & Easily - Elliott Tool

Once the tubes are pressurized, monitor the gauge on the top of the guns for any drop in air pressure. If the seal breaks, that indicates a tube leak is present. Similar to Pressure Test Guns, Vacuum Leak Test Guns create a vacuum tight seal on each tube end. The gun will then monitor for any loss of vacuum, indicating a tube leak.
