May I ask whether vertical storage tanks for Class A and B liquids buried underground can reduce the fire separation distance? ? Do buried Class A and B vertical or bedroom storage tanks also require fire dikes? ?
If it’s buried, then why make it a vertical storage tank? Buried horizontal storage tanks of Class A and B do not require fire dikes, but they need to have tank basins.
Sir, is there any source for this? Also, what is a pipe pool, and how is it made? ? Thank you for your patient answers, expert!
Burying can reduce the fire separation distance to some extent, but buried tanks are usually horizontal tanks, and measures must be in place to prevent leaks from reaching the soil
A so-called tank pool is made of reinforced concrete and resembles a pool. After the storage tank is in place, it is filled with sand. The storage tank foundation can be integrated with the tank basin floor. The distance between tank ponds and storage tanks is generally considered to be around one meter. A 1-meter-square water collection pit also needs to be considered inside the tank, along with a DN200 pipe for pumping out the water. The greatest advantage of installing a tank pool is that, in the event of a leak in the storage tank, the chemicals inside will not seep into the surrounding soil, making it easier to collect and handle them.
Mobile foam fire suppression systems can be used for above-ground horizontal storage tanks, buried vertical oil tanks, vertical storage tanks for Class B liquids, and above-ground storage tanks with a capacity of no more than 200 m3. ——Is it to avoid using fixed foam fire extinguishers?
Questions like this can be posted separately: Can vertical soil-covered oil tanks and vertical storage tanks for Class B liquids do without fixed foam fire extinguishers? https://bbs.hcbbs.com/thread-2824470-1-1.html (Source: Haichuan Chemical Industry Forum)
I replied, “If it’s going to be buried, why go through the trouble of building a structure?” ”This issue of. It is installed underground but in a vertical configuration; according to the standards, a fixed-type foam fire extinguisher is not required, so a horizontal type was not chosen.
May I ask if there is any basis for keeping the distance between tank ponds and storage tanks at around 1 meter? According to petrochemical regulations, a distance of 0.8 meters is sufficient between horizontal tanks. If the distance between a tank pool and storage tanks is 1 meter, what should be the distance between two adjacent storage tanks?
