【Major Chemical Equipment】447 – The 4000 m3 composite spherical tank with the largest single-volume range from 2021
Thread Content
The shell plates for the 4 large-scale composite plate spherical tanks, which were jointly designed by Sinopec Luoyang (Guangzhou) Engineering Company and Hefei General Machinery Research Institute and manufactured by Wuhan Yiyi Steel Structure Company of China First Metallurgical Group, totaled 216 pieces. These plates were prefabricated by the end of March 2021, and were all safely transported to Lianyungang, Jiangsu, for installation by the client company, Shenghong Refining & Chemical Co., Ltd. These 4 composite plate tanks are as follows: two 4000m3 spherical tanks for storing substandard liquefied gas, and two 4000m3 spherical tanks for storing naphtha. Once completed, they will set a record for the largest single-volume composite plate tank in China, filling a gap in the country’s infrastructure. Among them, the unqualified liquefied gas spherical tank has a diameter of 19,700 mm; its material is a composite sheet of 46+3 Q370R+S31603, and its weight is approximately 535 tons per unit ； The naphtha sphere tank has a diameter of 19,700 mm; its material is a composite plate of 26+3 Q345R+S31603, and the weight of each tank is approximately 342 tons. Since the hydrogen sulfide content in the medium stored in the tank (8541 ppm) is far above the normal level (≤50 ppm), a composite plate was used for its construction, and all nozzles were fabricated through a surfacing process using stainless steel welding materials. The inlet and outlet nozzles on the tank are currently the double-layer composite welded pipes with the smallest diameter and longest length available in China.
It’s tough in the scorching summer heat! Keep up with heat prevention and cooling! Clarify the key tasks! Safety analysis must not be neglected! ---------------------------------------------- The past decade has been a period of rapid development in China’s chemical industry, with the emergence of many new processes, products, and equipment. China’s chemical processing equipment has also seen significant progress, which has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and greater use of domestic equipment. We invite everyone to share their insights and discuss these topics together; let’s cheer for Made in China and support the development of chemical processing equipment! ------------------------------------------------------【Ministry of Emergency Management’s Special Inspection 2022】Summary Edition – Feel free to participate in discussions and self-inspections! ! ! ! https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=3418729 (Source: Huahai Chuanliu – Haichuan Network) Summary post for the 【Major Chemical Equipment in China】 series; being updated. https://bbs.hcbbs.com/thread-3366481-1-1.html (Source: Huahai Chuanliu – Haichuan Network)
