Successful jacking up of 160,000 cubic meter low-temperature ethane storage tank at Tianjin Nangang Ethylene plant

Thread Content

On December 7, 2024, the 160,000-cubic-meter low-temperature ethane storage tank for the externally-sourced light hydrocarbons project at Tianjin Nangang Ethylene Plant, constructed by Sinopec Fourth Construction Storage and Transportation Engineering Company, was successfully lifted into place. At the construction site, with 3 blowers started simultaneously and the concerted efforts of all employees involved, the dome of the storage tank, which has a diameter of over 80 meters and a weight of 670 tons, was lifted by more than 30 meters. At 10:36, the lifting process was successfully completed as the dome was connected to the pressure-bearing ring. This operation employed the \"air pressure lifting\" method, relying primarily on the coordinated control of the \"four major systems\" – power, balance, measurement, and sealing – to achieve a balanced and steady rise of all points on the dome. The successful jacking up of this storage tank is the company’s eighth major achievement in terms of jacking up large storage tanks in 2024. It also marks the complete completion of the main structural framework of the outer shell of these large storage tanks, paving the way for the next phase of work, which involves construction inside the tanks.
