Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a prefabricated crimping joint of a fiber-reinforced composite pipe. Background Art

[0002] At present, when connecting fiber-reinforced composite pipes, crimping joints are used as a common connection method. Usually, a heavy-duty crimping machine is used to extrude and deform the metal and clamp it on the surface of the pipe. It is usually necessary to ensure that the metal has sufficient thickness to prevent its "deformation" from recovering, thereby ensuring the connection effect. However, crimping while ensuring the thickness of the metal places high requirements on the specifications of the crimping machine.

[0003] With the improvement of technology, crimping structures have appeared on the market. By using heated crimping prefabricated joints on composite pipes, the connection of the pipe body is completed. Compared with the prior art method of using crimping machines, while ensuring the connection effect, it does not require high-power crimping machinery and is not limited by the size of the pipe diameter. However, for the existing prefabricated joints crimped on the pipe, on the one hand, during the crimping process of the prefabricated joints, they cannot effectively cooperate with the pipe and the relative position is not easy to fix; on the other hand, the crimping is completed by heating the joints, which has a certain impact on the joint structure.
