The DC medium thrust-free compensator can be widely used in pipelines in industries such as chemicals, petroleum, thermal power, and metallurgy, as well as in systems for urban central heating, including pipes installed in trenches or at high altitudes. At the same time, it facilitates pipeline design and installation, and saves a large amount of money (the cost of fixed supports alone is reduced by over 60%). 　　 Installation requirements: (1) When the wall thickness of the pipe sections welded to both ends of the compensator is ≥6 mm, groove preparation is necessary, and a hydraulic leak test must be conducted after welding as required. 　　(2) The sliding brackets and fixed brackets are installed according to the design; the ZTWB type is used, and all other aspects remain the same except for the thrust resulting from the working pressure of the medium, which is not taken into account. To ensure that the pipeline does not experience lateral displacement but instead expands and contracts axially, guide sliding supports should generally be installed at both ends of the compensator. At pipeline bends, fixed supports must be installed. 　　(3) The thermal insulation protection structures of the compensators are in the same path as the pipes, but they must not exert any restraining force on the expandable portion of the expansion joints. 　　(4) This compensator can be installed at its maximum installation length LMax under various ambient temperatures, without the need for stretching or compressing it.
