Is it appropriate to use rigid supports for the valve pedestals at the base of the tank?
Thread Content
For the larger-diameter outlets of oil tanks, two valves and one hose are generally installed; the first valve located near the tank mouth is usually called the root valve, and both valves should be supported by brackets. Rigid supports such as concrete are commonly used under the root valves of oil tanks on-site, but in the event of an earthquake, these rigid supports can cause the tank outlet to be torn apart, leading to problems. So please discuss whether it is appropriate to install rigid supports beneath the root valve, and whether elastic supports or dampers should be used
If elastic supports are to be used, should they be of the variable-type or constant-force type? It is said that a certain project used constant-force type supports.
Steel plates can be embedded in the tank base to provide triangular support for the root valve; this approach is relatively safe and simple. Using elastic supports, however, is more complicated.
Embedding steel plates on the tank foundation to provide triangular support for the root valve is inconvenient in practice, especially when it comes to valve maintenance; such support takes up a lot of space. This is a practical issue that exists in many organizations; it doesn’t work to place the support behind the hose, which is quite troublesome
Hello, I’m not sure how to solve the problem you mentioned
For our new tanks, we create an extended platform at the location of the root valve for the tank foundation; the top surface of this platform is at the same elevation as the ground level of the tank area, so it does not take up any operating space. In this way, the pivot points for the rigid support are integrated with the tank foundation, which prevents the decline of these pivot points due to ground settlement. I believe this also helps to mitigate the effects of earthquakes
