Leak prevention for the outer layer of the double-layer storage tank
Thread Content
Hello everyone. Abroad, there are large storage tanks with a double-layer design: the outer layer prevents leaks, while nitrogen is used to protect the interior, which eliminates the need for a retaining wall. Is there a similar design used in China? Please help me understand this. Thank you!
:P can consult an expert.
This question is too general; the role of the upper-level design cannot be simply understood as leak protection. What is its relationship with the relevant safety cofferdams? Facilities equipped with safety dikes are usually installed to deal with liquid material leakage incidents. Can nitrogen sealing solve this accident problem? Also, the construction of such items must be carried out in accordance with relevant **safety production standards** based on the specific equipment used. One must never take things for granted.
In China, even if you design it yourself, you’ll likely still need to add cofferdams, as the national standards are clear on that.
Similar to LNG double-volume tanks? ~~
Starting from the 3rd floor slab, people come out to scold others~~~~ In fact, the purpose of interlayer protection is to use nitrogen to contain the vapor phase of the leaked material, so that online alarm systems can detect it before the corrosion can penetrate the outer layer and allow the leak to reach the atmospheric environment; this way, the leak can be stopped at an early stage~~~~ Ordinary storage tanks in China do not have such standard design. Additionally, the bund surrounding the tank is a requirement mandated by safety standards for tank areas (as long as the medium falls within the scope of these standards)~~~~ Even when nuclear-grade protection is used, a bund is still necessary. Anyway, using materials from roughly two jars to make one jar – is the owner just extremely wealthy, or extremely wealthy, or extremely wealthy? ? ?
