Explanation of steam water hammer phenomenon? And what is the relationship between the size of the drain discharge? What is the relationship between thermal stress and warm pipes, between drain flow and pressure, and between steam condensation? Is water hammer caused by dimensions?
The causes of water hammer in the steam condensate piping network are as follows: 1. Steam enters the condensate system directly through a short circuit. This situation occurs quite frequently; for example, steam leaks out during the drainage of traps (equipment issues), or steam from heat exchangers enters the condensate system directly through the condensate tank (operational issues), and so on. 2. There is a pocket in a pipe within the condensate piping system. 3. There are pipes with high-grade steam condensate connected to them unintentionally, and these have not been detected. 4. When the pipeline has a change in diameter, especially at the enlarged section. 5. The destruction of insulation is, of course, a common issue during the extremely cold winters in Qinghai, as water hammer phenomena (condensation in pipelines) occur frequently
The steam flow velocity is very high, and the density of the condensate is much greater than that of steam. Therefore, driven by the fast flow of steam, the condensate moves at a high speed within the pipe, generating a large impulse (F=m.c), which results in significant destructive force from water hammer.
It’s not detailed enough. Is there a more professional explanation?
1. Steam water hammer is caused by some steam condensing into liquid, which leads to vibrations as steam from other areas rushes in rapidly. 2. It is more appropriate to use backflow discharge for dry steam or steam that constitutes the majority of the flow. 3. Installing a steam trap on the steam backflow system helps save heat and effort, though it comes at an economic cost. 4. As for the relationship between thermal stress and pipe warming, I work in production and haven’t yet understood it fully; however, as long as the pipe temperature rises, it is considered that the pipe has warmed up properly. The friend on the second floor gave a good answer!
The friend on the second floor gave a good answer! The main reason is that steam water hammer occurs due to some of the steam condensing into liquid, which causes vibrations as steam from other areas rushes in rapidly. Solution: Installing a steam trap on the reverse steam flow can resolve the issue, but it is costly.
