The gas holder in this project is approximately 62 meters high, about 38 meters in diameter, and weighs over 1,000 tons. It has a regular 20-sided shape, with a nominal volume of 50,000 cubic meters. It is used to store the coke oven gas, which is the main raw material used throughout the plant, and its storage pressure can reach over 8,000 pascals. Due to the large scale of the work, assembly and welding had to be carried out on site. Inflation jacking and inverted construction techniques were used, and after more than 2 months, the project was completed with a high quality, achieving a welding inspection pass rate of nearly 100%
