From the manufacturing of the shell plates to on-site installation, throughout the entire construction process, all employees of the company worked hard to overcome challenges and deliver meticulous workmanship； During on-site assembly, the project manager coordinated everything carefully, made precise adjustments, and ensured that such a large spherical tank was assembled accurately and within the shortest possible time frame ； Welding was completed with the highest quality, setting a new record for the installation of spherical tanks. To improve the mechanical properties of the welded joints of spherical tanks, better eliminate residual stresses, and enhance the quality and safety of these tanks, overall heat treatment must be carried out on them after the welding inspection is successful. Carrying out overall heat treatment on such a massive super-large spherical tank, with a volume and weight so great – heating the steel spherical shell weighing over 1,000 tons to 600±20°C and holding that temperature for 95 minutes – is a first of its kind both domestically and internationally! And it was completed successfully! However, our success was not accidental; it resulted from the effective combination of engineering experience and scientific methods. Drawing on our experience with 10,000 cubic meter spherical tanks as well as the relevant testing data, and with the guidance of experts and through collaboration with university specialists, we conducted simulated analyses of the entire heat treatment process. By integrating engineering experience with these analyses, we implemented effective processing techniques and innovatively adopted a dual-heating approach. After numerous tests and improvements, we finally developed a practical heat treatment plan that ensured the final treatment results met all the requirements specified in the design documents and relevant standards.

Impressive. Where is it used, and what media is collected?

I don’t know; I’ll check online and wait for an expert to answer

Take a look at this as well: 【HaiChuan Discussion Forum】Should one choose a 2000M3 spherical tank with 3 bands or one with 4 bands? https://bbs.hcbbs.com/thread-3057115-1-1.html (Source: Huahai Chuanliu – HaiChuan Chemical Industry Forum)

It’s amazing to find spherical tanks with a capacity of 100,000 cubic meters

20,000 cubic meters? Is it used to store low-pressure liquefied gas?

I don’t know; the article doesn’t mention its purpose

Do a simple calculation: what should be the diameter of a spherical tank with a volume of 20,000 cubic meters?
