I heard that the valves of pipelines cannot be installed inside fire dikes – is there such a rule?

Haven’t heard of it. Not practical enough. Is it intended for some specific medium?

There is no such rule, and it’s not necessary either. But it is also inconvenient to place valves that need to be turned on and off frequently inside a fire dike.

I haven’t heard of such a rule; it doesn’t seem very feasible. For example, in the pipeline from the tank outlet to the pump inlet within the tank area, a valve is often installed at the tank outlet. If it isn’t possible to install such a valve, wouldn’t it be necessary to run a section of pipe outside the fire dike first? It seems like a nozzle with a special function was pressed!

If it is installed inside the dike, how should it be isolated in the event of a fire? ?

A fire can occur inside the dike, and it is also set there; the purpose of the dike is to minimize the risk of fires, ensuring that they only occur within the dike

Yes, mainly to facilitate closing this valve in case of a fire, thereby achieving isolation.

It should be considered that the emergency shut-off valves on the material supply lines of storage tanks should not be located in fire-hazardous areas, so as to ensure that people can approach them easily to shut them off in case of a fire, thereby reducing the fuel supply to the fire. If it is necessary to install emergency shut-off valves in fire-hazardous areas, such valves should be fire-resistant remote-controlled valves. I’m not sure if it’s correct.

There is no such regulation; it’s just that valves on fire-fighting pipes are not allowed to be located inside fire dikes, so as to facilitate operations in case of a fire.

The isolation valves for entering and leaving the plant area are generally installed outside the fire wall

The valve of the emergency shut-off valve is supposed to be installed outside the fire dike; no other requirements seem to exist

For flammable media, a manual valve + fuse valve can be added at the start of the pipeline.

The process valves in the tank area are generally located inside the fire dike, while the valves used for firefighting are outside the fire dike
