Water hammer in steam condensate pipeline

After the technical modification of the reboiler steam in the pre-distillation tower, it was connected to the deaeration tank, resulting in significant liquid slugging in this pipeline.

Water hammer in steam condensate pipelines is usually caused by the following reasons: 1. The steam in the pipeline condenses too quickly, and the resulting condensate water cannot be drained in time, leading to water hammer. 2. If gas, such as air or steam, remains in the pipeline and is not completely expelled, it mixes with the condensate water to cause water hammer. 3. The pipeline design is unreasonable; for example, the slope is insufficient or there are too many bends, resulting in poor water flow. 4. Improper design of the drainage system or malfunctions in components such as drainage valves, resulting in delayed removal of condensate water. 5. Scaling or deposits on the inner wall of the pipeline interfere with the normal flow of water. A thorough inspection of the piping system and drainage is required to identify the specific cause and take appropriate action. .

The 3rd floor is the correct answer; look at how the original poster checked the situation item by item – water hammer must have occurred due to a conflict between steam and liquid
