The title does not meet the requirements; it does not describe the problem, which makes it difficult to engage in discussion. I have never seen fire water enter a spherical tank – usually gases such as nitrogen are used, while fire water is used for spraying in the form of coils inside the tank
It should be the water injection line at the bottom of the tank. Numerous accidents have shown that the sealing points such as flanges and valves at the bottom of spherical tanks are most prone to leakage. After adding a water injection line to the spherical tank, in the event of a leak at the bottom, water can be injected into the tank through this line. Since the density of water is much greater than that of liquefied petroleum gas, water settles at the bottom of the tank; as a result, the material that leaks from the leak site is water rather than liquefied petroleum gas, which facilitates and ensures safety in dealing with the leak.
The water supply line uses industrial water, while fire-fighting water is separate and must not be used for other purposes; perhaps the original poster made a mistake
The water injection line at the bottom of liquid hydrocarbon spherical tanks can be fed with water from fire protection sources. The design specifications for the water injection system in liquefied hydrocarbon sphere tank areas issued by Sinopec in 2011 clearly state: \"A constant-high-pressure fire water system can be used as the water source for injecting water into the spheres in the event of an accident.\" When designing the official website for a stable-high-pressure fire protection water system, it is necessary to take into account the water demand of 50–100 tons per hour in the event of a leak in the spherical tank.
Thank you for the explanations from the 3rd and 5th floors!
