【Haichuan Expands Horizons】Do you know how large double-layer spherical tanks are manufactured?

A technical achievement of China First Metallurgical Group has won the first prize in the category of technical inventions at the MCC Group Science and Technology Awards. China First Metallurgical Group, 2019-04-11. In the context of the current energy transition and new trends toward sustainable development, there is significant potential for further growth in China’s natural gas consumption. **It is necessary to vigorously develop the natural gas industry, accelerate independent innovation in key energy equipment, and develop natural gas storage technologies that are suitable for modern energy industry frameworks. Recently, at the conference for the implementation of the MCC Group’s Technology Innovation \"2020 Plan,\" the research on \"Key Technologies for the Construction of Insulated Cryogenic Double-Layer Spherical Storage Tanks\" carried out by China First Metallurgical Group’s Steel Structure Company won the first prize in the category of technical inventions at the MCC Group Science and Technology Awards. The achievements of the project \"Key Technologies for the Construction of Adiabatic Cryogenic Double-Sided Spherical Storage Tanks\" include 8 authorized invention patents, 2 provincial or ministerial-level construction methods, and 2 scientific papers published in core journals. As verified by the Science and Technology Achievement Appraisal Committee of MCC Group, this achievement has reached the international advanced level. Based on the key project of **\"West-to-East Gas Transmission,\" this technology focuses on the largest austenitic stainless steel LNG cryogenic double-layer spherical tanks in China. It conducts comprehensive research on new technologies related to the structural design of such double-layer spherical tanks, their precise construction, and efficient insulation, with the aim of developing more safe, precise, and efficient methods for building large-scale double-layer spherical tanks. This effort is intended to contribute positively to the strategic development of energy equipment and energy security.

"\"Double-layer spherical tank\":o :o I’ve never seen or heard of it. Is the inner spherical tank floating inside? Just like a baby in its mother’s womb:o

Just take a look at the third floor and you’ll understand right away ==================================== Hehe, you’ve never seen it before, have you?

LNG cryogenic storage tanks are all double-walled and cylindrical in shape; the inner layer is made of cryogenic steel, the outer layer is a concrete shell, and the space in between is filled with insulation material to prevent heat loss. It’s designed in a spherical shape, with a metal outer shell; this definitely increases the cost significantly, and the installation process is difficult to control.

I just thought about this: spherical tanks are not suitable for large-scale use, such as in port receiving stations. However, they require simpler foundations compared to regular storage tanks

Cylindrical cryogenic storage tanks are the common choice; adopting a spherical shape must be driven by specific operational requirements, otherwise it doesn’t make sense.

Please note that the pillar is divided into three sections–three colors. Why is it divided this way?

Different coatings are used to prevent the transfer of cold energy across different materials.
