How to prevent liquid hammer?

The cause of water hammer is that water and gas are in an azeotropic state and are involved in unstable flow processes; as a result, sometimes some of the substance changes from gas to liquid state, while at the same time some other substance changes from liquid to gas state. This exerts irregular forces on the pipes, causing them to deviate from their normal path or even leading to their destruction. The key to slugging is to properly control the liquid level and pressure changes, preventing saturated liquid from entering the gas phase; at the same time, the pressure changes should not be too large to avoid azeotropy.

When driving without a drain, and pressure gas is generated during pipeline inflation, causing the condensate in the pipeline to be forced through the lines – does this constitute water hammer?

Water hammer needs to be detected promptly and handled properly

It is necessary to drain the liquid from the flare separation tank in a timely manner, especially in winter; it is very dangerous for the flare lines to contain liquid, as this can cause pressure buildup in other systems.

We call it water hammer here, hehe! Water hammer is quite dangerous, especially in high-pressure pipelines; when it occurs, the effects can be severe – the entire pipeline may sway like noodles, and the noise generated can cause the platform to shake violently. The worst outcome is that the pipeline breaks completely.

1. After the water pump trips, a \"thud\" sound is heard in the pipeline; this is generally not caused by water hammer (commonly referred to as hydraulic shock), and with 99% probability it is the sound produced when the check valve returns to its original position. 2. Concept of water hammer: A phenomenon in pressurized pipelines in which significant pressure fluctuations occur as a result of sudden changes in fluid flow velocity. Sudden opening and closing of gates in pipeline systems, sudden shutdown of water pumps in water supply pipelines, operation of the guide vanes of turbines, and turning off faucets in indoor sanitary fixtures can all cause water hammer. Water hammer can cause severe vibrations in pipeline systems; the calculation of indirect water hammer requires knowledge of how flow velocity changes over time, and it can lead to noise and cavitation. Understanding the variation patterns of water hammer pressure is of great practical significance for the design of water conveyance pipelines and for reducing the destructive effects of water hammer. The fundamental issue in water hammer is the calculation of the maximum pressure, which generally occurs at the wave emission point (such as at a valve).

The exhaust gas from the torch is a saturated gas; water condenses within the pipelines, or the design lacks sufficient flexibility, resulting in no drain at the lowest points

There is condensate in the flare pipeline, causing the gas to contain water and resulting in liquid slugging. The drainage should be strengthened regularly.

It should be called water hammer. As mentioned above, drain pipes should be installed at the lowest points to allow for regular drainage. Foreign drain valves are all equipped with dual valves. Also, make sure to close the drain valve immediately after drainage is complete to prevent air from entering the vent pipe.

The cause of fluid hammer in torch pipelines is the large amount of condensate present within them; moreover, when the valves in various sections are opened wide, the gas pushes the liquid column forward, striking the pipes like water hammer. The destructive force of this phenomenon is significant – in mild cases, the pipes may shift, while in severe cases they can even break. Strengthening the drainage of the flare pipeline’s drain can prevent this.
