Перевожу текст про паровые турбины и конденсаторы электростанции. В тексте встретился термин target inserter.

В сети нет ничего толкового на русском языке. Находит что-то подобное:

A high-pressure high-velocity target inserter for use in steam cleaning. The target inserter uses an actuator connected to a tube assembly, which connects to a test line. The target inserter uses packing to prevent high-pressure steam from being released through the target inserter when the target rod is inserted and withdrawn from the line. In the preferred embodiment, the target rod passes through a remotely operated actuator controlled valve and a remotely controlled actuator controller, such that the operator is kept a safe distance away from the inserter when the access valve to the line is open.

В моем тексте как раз речь про продувку паром и очистку. Данный target inserter, как указано, должен быть установлен на участке трубопровода (конденсатора). Всё)

In the prior art, such as described by Bloch in U.S. Pat. No. 4,853,014, low-pressure high-velocity steam is used for interior cleaning of pipes. Pressure is built up in a boiler, and then released through the lines to be cleaned. The lines are then allowed to cool while steam pressure is built up again in the boiler. This blow cycle is repeated until the line is clean. To determine if the steam (and therefore the line) is clean, a piece of soft metal called a target is supported across the interior of the terminal portion of the line. The target is inserted into the line (typically between blow cycles), steam is blown through the line, and the target then removed. Pits in the metal target are caused by debris from the line striking the metal. These pits are counted to quantify the level of cleanliness of the line. When the line is still “dirty”, numerous pits are observed. As the line becomes cleaner, there are fewer small debris particles being pushed by the steam, and thus there are fewer pits in the target. The steam is then vented out the line through an expansion chamber, into which Bloch introduces a decelerating mist for noise control. While this method takes advantage of the flushing and cavitational forces provided by steam at near sonic velocity, being at low pressure requires a high volume of water to adequately flush out the line. Further, target insertion/removal must be performed at low pressure, typically between blow cycles, due to the prior art design limitations of the target inserter. Finally, the steam can only be used in a single unit, since there is inadequate pressure to pipe the steam to a second unit to clean it as well.

а вставляемый отражающий щиток не хотите?

Не хотим. В патенте вполне конкретно описано назначение target

The target is inserted into the line (typically between blow cycles), steam is blown through the line, and the target then removed. Pits in the metal target are caused by debris from the line striking the metal. These pits are counted to quantify the level of cleanliness of the line.
