He looked at the development of chemical technology in the past ten years and praised China's prosperity and strength in the prosperous age. It is more lively and exciting with everyone's participation. [Ten Years of Development of Chemical Equipment] Continue to update the summary post. Welcome to participate in the discussion https://bbs.hcbbs.com/thread-3576046-1-1.html Prevention first, life first -------------------------------------------------- At 10:00 on April 5, 2023, the product separation tower of the Yantai Wanhua high-performance new materials integration project, manufactured by Ningbo Tianyi Manufacturing Company, a subsidiary of Ningbo Engineering Company, set off from the Xize Wharf of Xiangshan Port and was sent to the project construction site in Shandong. It is reported that this "Big Mac" with a length of 138.6 meters, a diameter of 10.8 meters, and a weight of 2,558 tons has set a new record for the longest product separation tower in the world for overall manufacturing, overall transportation, and overall delivery. This product separation tower took eight months to manufacture. It is equivalent to the "kidney" of the propane dehydrogenation unit and is the quality gatekeeper for new material products. Compared with ordinary products, the separation tower of this product is large in size, heavy in tonnage, and high in air pressure, and has stricter requirements on manufacturing process and safety and quality.
The volume of this product separation tower is equivalent to about 1,000 cars. During the manufacturing process, the saddle placement angle must be checked multiple times to ensure that the error does not exceed 2 mm to ensure that the auxiliary transportation platform does not derail, achieve precise control of straightness, improve the quality of welding joints, and provide guarantee for the levelness of the internal tray installation of subsequent equipment. Picture product The separation tower is a large-diameter, ultra-long piece of equipment that effectively ensures the ovality and straightness of the tower body, which is a challenge faced by equipment manufacturing. Welding engineer Xi Xiubin said that in order to control the ovality of the equipment, large sections of the equipment are formed in a vertical state, consistent with the equipment's operational status, and "meter" braces are installed near the upper and lower openings of the large sections of the equipment to improve production safety. In order to avoid welding deformation caused by large welding volume, Tianyi Manufacturing sets up anti-deformation supports before each welding to monitor the ovality in a timely manner.
This is too big, haha, it’s really size 10.
