Are the steel and concrete used in constructing LNG storage tanks special brands designed to withstand low temperatures?
For the several small plants and stations that have been built, the concrete in the tank areas needs to be frost-resistant and impermeable
Is this much more expensive than regular cement?
It must be expensive; one side is worth dozens of yuan more
Is it an underground LNG storage tank?
If it is an above-ground tank, it is not necessary; there is a glass brick insulation layer at the bottom of the pipe.
Above-ground storage tanks, the concrete tanks that are above ground – do those also require low temperatures?
Above-ground storage tanks, the concrete tanks that are above ground – do those also require low temperatures?
In the case of fully enclosed LNG storage tanks, the concrete used for the outer tank is usually C50 low-temperature concrete； Reinforcing bars come in two types: ordinary bars and low-temperature bars
The metal tanks on the ground also need to be protected from leakage and freezing
In China, the main manufacturers of low-temperature steel bars are Ansteel, Magang, etc. For concrete, the mix proportions are determined based on tests conducted according to the design documents; some design agencies require the addition of crack-resistant fibers.
