Polytetrafluoroethylene multilayer compression-resistant pipe

The utility model relates to a polytetrafluoroethylene multi-layer pressure-resistant pipe which comprises a pipe body, fixing assemblies are arranged at the two ends of the pipe body, each fixing assembly comprises a fixing circular plate, and one side edge of each fixing circular plate is fixedly connected with an outer ring block and an inner ring block located on the inner side of the outer ring block. A containing cavity used for containing the end face of the pipe body is formed between the outer ring block and the inner ring block, the two ends of the pipe body are inserted into the containing cavity, and the pipe body comprises a base layer and a polytetrafluoroethylene layer. A plurality of groups of pipe bodies can be quickly spliced, after splicing is completed, the outer side faces and the inner side faces of the two ends of the pipe bodies are stably fixed through the outer ring blocks and the inner ring blocks, and even if the pipe bodies are subjected to external pressure, the pipe bodies canno
