Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation pipes, in particular to an inner wall supporting device for installing thermal insulation pipes. Background Art

[0002] Insulated pipe is the abbreviation of insulated pipe. Insulated pipe is used for the transportation of liquid, gas and other media. It is used for thermal insulation of pipelines in petroleum, chemical industry, aerospace, hot spring, military, central heating, central air conditioning, municipal and other fields. Insulated pipes will use pipe installation components during installation. In the process of pipe connection, an inner wall support device for the installation of insulated pipes is required to support the inner wall of the pipe.

[0003] Announcement No. CN219221659U discloses an inner wall support device for installing an insulated pipe, comprising an insulated pipe body, an inner wall support mechanism is arranged on the inner wall of the insulated pipe body, a convenient connection mechanism is arranged on the outer wall of the insulated pipe body, the inner wall support mechanism comprises an inner support reinforcement unit and a fixed spacing unit, and the convenient connection mechanism comprises a sealing connection unit and a pipe locking unit;

[0004] There may be two problems when using it. First, when the device supports the inner wall of the pipe, it is necessary to customize the diameter of the support device according to the inner wall diameter of different pipes, so that the support device can only be used for special pipes, which makes the popularization cost of the device high and the application range narrow; second, after multiple support devices are connected, since the inner diameter of the pipe is the same as the outer diameter of the support device, it is inconvenient to take out the support device during later disassembly and maintenance, so that the staff needs to disassemble multiple connecting devices one by one, which makes the operation time-consuming and labor-intensive. Therefore, we propose an inner wall support device for the installation of insulated pipes. Utility Model Content
