According to news from April 18, 2025, **information from the Intellectual Property Office shows that Maoming Gravity Petrochemical Equipment Co., Ltd. has obtained a patent titled “A Coiled Tubing Reactor,” with the approval announcement number CN222766341U; the application was filed in April 2024. According to the patent abstract, the present utility model relates to the technical field of petrochemical equipment. Specifically, it pertains to a shell-and-tube reactor with helically arranged tubes. The reactor comprises multiple straight sleeves and multiple bent tubes; each straight sleeve consists of an inner tube and an outer tube, with the inner tube passing through the outer tube to form an annular straight jacket flow channel ； The inner tubes of multiple straight sleeves are connected in series via elbows to form a medium flow channel for transporting the reaction materials and carrying out the reaction, while the straight jacket flow channels of these multiple straight sleeves are connected in series to form a cooling flow channel for transporting the cooling medium. Multiple straight tubes are arranged in rows, with two or more rows in total; the ends of each bent tube are connected to the ends of straight tubes in different rows, so that the straight tubes and bent tubes form a spiral arrangement. The overall structure is more compact; its height and center of gravity are reduced when it is in a horizontal position. This facilitates transportation to the installation site after assembly at the manufacturing plant, makes lifting easier, reduces the time required for on-site construction, and enhances safety during on-site work. The floor area occupied by the overall structure is reduced, and the space required for lifting the entire structure during construction and installation is minimized. According to Tianyancha, Maoming Gravity Petrochemical Equipment Co., Ltd. was established in 1995 and is located in Maoming City; it is a company that specializes in the manufacturing of specialized equipment. The registered capital of the enterprise is 152.020748 million RMB. According to the big data analysis conducted by Tianyancha, Maoming Gravity Petrochemical Equipment Co., Ltd. has participated in 341 bidding projects. In terms of property-related information, it has 3 trademark records and 426 patent records; in addition, the company holds 111 administrative licenses.
