The outer wall of the pipe is tightly fitted with the protective film, and the outer wall of the protective film is tightly fitted with the wrapping cotton; the operator directly holds the protective mechanism for installation and docking. When in use, the internal pipe is connected and the external protective film is used to wrap the connection for surface protection. At the same time, the internal wrapping cotton is used to wrap it again, and then the internal adhesive tape is used to connect it, so that the materials are fitted and docked, which is convenient for bonding and fixing operations, and at the same time, it is convenient to place the pipe in position. It is wrapped with the internal protective film and wrapping cotton for internal protection, which can isolate the outside and reduce corrosion damage to the internal pipe.
