Multiple-choice question: Pipe supports are used wherever pipes are laid; they are also known as pipe saddles or pipe mounts, etc. It serves as a supporting structure for pipelines; depending on the operating performance of the pipelines and the layout requirements, pipe racks are divided into fixed and movable types. The function of a fixed support is ( ). A. To evenly distribute the thermal expansion of the pipes between the compensators. B. To ensure the proper operation of the compensators. C. To prevent the pipes from being damaged or undergoing excessive deformation due to excessive local thermal stress. D. To restrict the thermal deformation of the pipes. Answer: ABC
