Description

Technical Field

[0001] This utility model relates to the field of pipe technology, and in particular to a hydrogen embrittlement resistant composite hydrogen transport pipe. Background Technology

[0002] Pipes are essential materials for construction projects. Commonly used pipes include water supply pipes, drainage pipes, gas pipes, heating pipes, electrical conduits, and rainwater pipes. With the development of science and technology, the pipes used in home decoration have also gone through the development process of ordinary cast iron pipes → cement pipes → (reinforced concrete pipes, asbestos cement pipes) → ductile iron pipes, galvanized steel pipes → plastic pipes and aluminum-plastic composite pipes.

[0003] Currently, pipes are used in many environments. Existing pipes are mainly made of rubber, which is prone to hydrogen embrittlement when transporting hydrogen. In addition, existing pipes tend to have poor strength after long-term use, and their corrosion resistance is also somewhat lacking, reducing the functionality of the pipes. Therefore, we propose a hydrogen embrittlement-resistant composite hydrogen transport pipe to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a hydrogen embrittlement resistant composite hydrogen transport pipe to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hydrogen embrittlement resistant composite hydrogen transport pipe includes a pipe body, the pipe body comprising a first hydrogen embrittlement resistant layer, a first reinforcing layer, a first corrosion resistant layer, a second hydrogen embrittlement resistant layer, and a second reinforcing layer, with the second corrosion resistant layer connected to one side of the pipe body.

[0007] In a further embodiment, the outer surface of the pipe body is connected to the inner wall of the first hydrogen embrittlement resistant layer, and the outer surface of the first hydrogen embrittlement resistant layer is connected to the inner wall of the first reinforcing layer.

[0008] In a further embodiment, the outer surface of the first reinforcing layer is connected to the inner wall of the first anti-corrosion layer, and the inner wall of the pipe body is connected to the outer surface of the second anti-hydrogen embrittlement layer.

[0009] In a further embodiment, the inner wall of the second hydrogen embrittlement-resistant layer is connected to the outer surface of the second reinforcing layer, and the inner wall of the second reinforcing layer is connected to the outer surface of the second corrosion-resistant layer.

[0010] In a further embodiment, both the first and second anti-hydrogen embrittlement layers are graphene composite nano-ceramic coatings, and both the first and second reinforcing layers are carbon fiber nylon.

[0011] In a further embodiment, both the first anti-corrosion layer and the second anti-corrosion layer are polyamide-imide.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device facilitates the transport of hydrogen through the pipe body. Combined with the first and second anti-hydrogen embrittlement layers, it enhances the pipe body's resistance to hydrogen embrittlement, preventing hydrogen embrittlement and reducing the probability of pipe bursting. Furthermore, the first and second reinforcing layers improve the pipe body's strength, giving it higher pressure resistance. In addition, the first and second anti-corrosion layers enhance the pipe body's corrosion resistance and extend its service life. Attached Figure Description
