Let’s take a look at the ten-year development of chemical technology; it’s truly a testament to the prosperity and strength of China in this golden era. This post serves as an opening invitation for everyone to participate in the discussion—the more people join, the livelier it becomes. With your participation, this forum becomes even more wonderful! [Ten Years of Great Development in Chemical Equipment] This is a continuously updated compilation post; all are welcome to join the discussion: https://bbs.hcbbs.com/thread-3576046-1-1.html Prevention comes first; human lives are paramount. ----------------------------------------- At 10:00 on April 5, 2023, the product separation tower for the Yantai Wanhua High-Performance New Materials Integrated Project, manufactured by Ningbo Tianyi Manufacturing Co., Ltd.—a subsidiary of Ningbo Engineering Company—was shipped from Xize Wharf in Xiangshan Port to the project site in Shandong Province. It is reported that this \"giant\", which is 138.6 meters long, 10.8 meters in diameter, and weighs 2,558 tons, has set a new world record for the longest length of a product separation tower in terms of overall manufacturing, transportation, and delivery. This product separation tower took 8 months to manufacture; it acts as the \"kidney\" of the propane dehydrogenation unit and is responsible for ensuring the quality of new material products. Compared to ordinary products, this product features a larger separation tower, greater weight per ton, and higher pressure, requiring stricter standards in terms of manufacturing processes as well as safety and quality.

The volume of this product separation tower is equivalent to that of about 1,000 cars. During the manufacturing process, the angle at which the saddle is positioned must be checked multiple times, with the error allowed to be no more than 2 millimeters. This ensures that the auxiliary transportation platform does not derail, permits precise control of straightness, improves the quality of the weld joints, and provides a guarantee for the levelness of the tower trays inside the equipment in subsequent steps. The product separation tower is a device with a large diameter and extremely long length; ensuring the ellipticity and straightness of the tower body represents a challenge in equipment manufacturing. Welding engineer Xi Xiubin explained that in order to control the ellipticity of the equipment, large sections of it are formed in a vertical position, which is consistent with its operating condition; moreover, \"M\"-shaped supports are installed near the upper and lower ends of these large sections to enhance the safety factors during production. To avoid welding deformation caused by large amounts of welding, Tianyi Manufacturing installs anti-deformation supports before each welding operation and monitors the ellipticity in a timely manner.
The separate tower set sail from Xiangshan Port in Ningbo on the morning of April 5, traveling day and night towards the north, and arrived at Luanjiakou Port in Weiyang, Penglai at 6:30 p.m. on April 9. After unbinding the equipment and waiting for the optimal time for tidal operations, the land transport process was initiated at 12:30 p.m. on April 10.
