According to information from the Intellectual Property Office as of May 8, 2025, **Jiangsu Chengde Steel Pipe Co., Ltd. has been granted a patent titled “A device for flattening the ends of seamless steel pipes,” with the approval number CN222817707U. The application was submitted in July 2024. The patent abstract indicates that this utility model relates to the field of steel pipe flattening technology, and discloses a device for flattening the ends of seamless steel pipes. It includes a workbench and legs; a movable platform is arranged at the top of the workbench. Sliding grooves are provided at the front and rear ends of the top surface of the workbench. Support columns are fixedly attached at the four corners of the top surface of the workbench, and a top plate is fixedly connected to the tops of these support columns. This equipment for flattening the ends of seamless steel pipes is equipped with components such as connecting blocks; by activating the cylinder, the first telescopic rod can be used to move the positioning seat at the bottom downward. Meanwhile, the directional rod at the bottom moves within the positioning groove, allowing the steel pipe to be positioned on the moving platform thanks to the “V”-shaped groove inside the positioning seat. Since the positioning seats are symmetrically arranged on both sides of the pressing base, it is easy to move the steel pipe after one end has been flattened, thereby facilitating the positioning and flattening of the other end as well. This makes the equipment more practical and solves the problem of difficulty in quickly positioning the steel pipe.
