Description

Technical Field

[0001] The utility model relates to the technical field of seamed pipes, in particular to an aluminum alloy composite seamed pipe. Background Art

[0002] Aluminum alloy composite seamed pipe is one of the seamed pipes. It has the characteristics of easy welding, convenient processing and forming, environmental protection, economic applicability, etc., so it is widely used. However, the existing aluminum alloy composite seamed pipe still has some disadvantages, such as its single structure, which is often a single pipe body, which causes the ports at both ends to be very easy to deform and dent after being compressed, which will affect the use of the entire seamed pipe, and also affect its overall structural strength, and also reduce the service life of the aluminum alloy seamed pipe. Moreover, the deformed aluminum alloy composite seamed pipe also needs secondary processing in the later stage, which is very time-consuming and labor-intensive. For this reason, we propose an aluminum alloy composite seamed pipe. Utility Model Content

[0003] The utility model aims to provide an aluminum alloy composite seamed pipe to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] An aluminum alloy composite seamed pipe comprises a seamed pipe body, the outer wall of the seamed pipe body is provided with a high temperature resistant epoxy resin layer, the outer wall of the high temperature resistant epoxy resin layer is provided with a pressure resistant layer, center blocks are provided at the centers of the front and rear end surfaces of the inner cavity of the seamed pipe body, support rods are provided around the outer wall of the center block, arc-shaped connecting blocks are provided at the ends of the support rods away from the center blocks, and clamping blocks are provided at the ends of the arc-shaped connecting blocks away from the support rods, and clamping grooves matching the clamping blocks are provided around the front and rear end surfaces of the seamed pipe body.

[0006] Furthermore: the outer wall of the pressure-resistant layer is provided with a frosted layer, and the outer wall of the frosted layer is provided with a waterproof layer.

[0007] Furthermore: one end of the arc-shaped connecting block away from the supporting rod is fitted on the inner wall of the inner cavity of the seamed tube body, and the arc-shaped connecting block and the supporting rod are fixedly welded.

[0008] Furthermore: the inner wall of the inner cavity of the seamed pipe body is provided with a galvanized anti-rust layer, the end of the clamping block away from the arc-shaped connecting block is provided with an arc-shaped contact, and the clamping groove is provided as an arc-shaped groove.

[0009] Furthermore: the front and rear end surfaces of the seamed pipe body and the outer side surface of the arc-shaped connecting block are arranged in the same horizontal plane, and the front and rear end surfaces of the seamed pipe body and the outer side surface of the arc-shaped connecting block are fixedly welded.

[0010] Furthermore: there are four groups of support rods in total, and the four groups of support rods are fixedly welded and arranged around the outer wall of the central block at equal distances.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The aluminum alloy composite seamed pipe can insert a clamping block into a clamping groove after the pipe body forming process is completed, so that the reinforcing member composed of the center block, the support rod and the arc-shaped connecting block can be installed on the front and rear end surface ports of the seamed pipe body. The cooperation of the center block, the support rod and the arc-shaped connecting block can effectively increase the structural strength of the front and rear end surface ports of the seamed pipe body, so that it is not easy to deform and dent after being compressed. Such an arrangement not only does not excessively increase the weight of the aluminum alloy composite seamed pipe, but also greatly increases its structural strength, thereby extending its service life.
