Flame-proof PC tube used for line protection

Abstract

The invention discloses a flame-proof PC pipe for line protection, which comprises a pipe body, and the inner and outer sides of the pipe body are respectively provided with an ABS resin flame-retardant layer and a polyvinyl chloride anti-corrosion layer, and the ABS resin flame-retardant layer The inner side is coated with ATO antistatic coating, the outer side of the polyvinyl chloride anti-corrosion layer is provided with a waterproof layer, the two ends of the pipe body are respectively provided with flexible joints and rigid joints, and the end of the flexible joint away from the pipe body is provided with A connecting ring, the flexible joint and the rigid joint are threaded through the connecting ring. In the present invention, in the process of line installation, people can combine multiple identical PC pipes with rigid joints and flexible joints according to needs to extend the length of the pipeline. The installation is convenient and quick, time-saving and labor-saving, and the structure is simple. It is light in size, has good flame retardancy and corrosion resistance, and can effectively strengthen the protection of line cables. It is suitable for various harsh environments and has a long service life.

Description

technical field [0001] The invention relates to the technical field of pipes, in particular to a flameproof PC pipe used for line protection. Background technique [0002] PC tubes are widely used in electric lines to protect line cables. Traditional PC tubes used for line protection have poor flame retardancy and corrosion resistance, have strict requirements on the use environment, and have a small scope of application. The PC tubes used for line protection are not equipped with a device for interconnection. During the pipeline installation process, it is necessary to combine multiple identical PC tubes with the help of external tools to increase the length of the pipeline. The installation is not convenient enough. It is time-consuming and labor-intensive. In addition, the traditional PC tube does not have antistatic and waterproof functions, and has poor protection effect on line cables. Contents of the invention [0003] The object of the present invention is to prov...
