[0002] The use of composite steel pipes is essential for facilitating the transportation and support of materials.

[0003] To this end, patent CN201396527Y discloses a multi-component composite steel pipe formed by self-propagating combustion within a steel pipe under centrifugal force. It includes a steel pipe matrix, within which a corundum layer and a polymer layer are sequentially arranged. This invention possesses excellent comprehensive properties such as wear resistance, acid resistance, alkali resistance, scale prevention, radiation resistance, and hydrolytic aging resistance, and can be widely used in industries such as power, metallurgy, coal, petroleum, chemical, and machinery.

[0004] The composite steel pipes mentioned above have insufficient overall strength during use, and their outer surface may be damaged during friction, leading to oxidation of the internal material, thus failing to meet actual usage requirements. Utility Model Content

[0005] The purpose of this invention is to provide a composite steel pipe with internal reinforcing ribs to solve the defects of existing composite steel pipes, such as insufficient strength and lack of wear resistance and oxidation prevention.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a composite steel pipe with internal reinforcing ribs, comprising a steel pipe base layer and a buffer layer;

[0007] A buffer layer is provided on the outer side of the steel pipe base layer, and a reinforcing structure is provided on the inner wall of the steel pipe base layer;

[0008] The reinforcing structure includes a covering layer on the inner wall of the steel pipe base, reinforcing ribs uniformly arranged inside the covering layer, a filling layer on the inner wall of the covering layer outside the reinforcing ribs, and an anti-corrosion layer on the inner wall of the covering layer.

[0009] A protective structure is provided on the outer wall of the steel pipe base.

[0010] Preferably, the reinforcing ribs are evenly distributed inside the covering layer, and the reinforcing ribs are designed in a grid pattern inside the covering layer.

[0011] Preferably, the filler layer is carbon fiber.

[0012] Preferably, the anti-corrosion layer is an epoxy resin layer.

[0013] Preferably, the protective structure includes an adhesive layer disposed on the outside of the steel pipe base layer, a wear-resistant layer disposed on the outside of the adhesive layer, and reinforcing blocks uniformly disposed on the outer wall of the wear-resistant layer.

[0014] Preferably, the wear-resistant layer is an aluminum oxide layer.

[0015] Preferably, the reinforcing blocks are evenly distributed on the outer wall of the wear-resistant layer.

[0016] The composite steel pipe with internal reinforcing ribs provided by this utility model has the following advantages:

[0017] By incorporating a reinforced structure, the main body of the reinforcing ribs inside the coating layer is designed in a grid pattern, which facilitates the overall strength of the steel pipe. Furthermore, a carbon fiber filling layer is uniformly arranged inside the coating layer on the inner side of the reinforcing ribs, which further strengthens the steel pipe. On the inner side of the coating layer, an epoxy resin anti-corrosion layer is provided, which increases the corrosion resistance of the inner wall of the device, thereby achieving the purpose of facilitating the overall strength of the composite steel pipe.

[0018] By incorporating a protective structure, a wear-resistant layer is bonded to the outside of the buffer layer via an adhesive layer. This wear-resistant layer is a dense alumina film, which facilitates the improvement of the device's wear resistance and prevents oxidation of the material on its inner side, thereby achieving the purpose of providing protective performance for the composite steel pipe.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 The present invention provides a composite steel pipe with internal reinforcing ribs, comprising a steel pipe base layer 1 and a buffer layer 2.

[0027] Reference Figures 1-4 As shown, a buffer layer 2 is provided on the outer side of the steel pipe base 1, and a reinforcing structure 3 is provided on the inner wall of the steel pipe base 1. The reinforcing structure 3 includes a covering layer 301 provided on the inner wall of the steel pipe base 1, reinforcing ribs 302 uniformly arranged inside the covering layer 301, a filling layer 303 provided inside the covering layer 301 outside the reinforcing ribs 302, and an anti-corrosion layer 304 provided on the inner wall of the covering layer 301. The reinforcing ribs 302 are evenly distributed inside the covering layer 301 and have a grid-like design inside the covering layer 301. The filling layer 303 is carbon fiber, and the anti-corrosion layer 304 is an epoxy resin layer.

[0028] In order to increase the overall strength of the composite steel pipe during use, a reinforcing structure 3 is set up, which in turn sets up a coating layer 301 inside the steel pipe base layer 1, and sets up a grid-shaped reinforcing rib body 302 inside the coating layer 301 to enhance the strength of the device. Inside the coating layer 301 inside the reinforcing rib body 302, a filling layer 303 is set up. The filling layer 303 is carbon fiber, which has the advantages of high specific modulus, high specific strength, high temperature resistance, and creep resistance, thus facilitating the improvement of the overall strength of the device. Inside the coating layer 301, an anti-corrosion layer 304 is set up. It is made of epoxy resin, which facilitates the improvement of bonding strength and chemical corrosion resistance, thus greatly increasing the functionality of the device.

[0029] Reference Figure 1 , Figure 2 and Figure 5 As shown, a protective structure 4 is provided on the outer wall of the steel pipe base 1. The protective structure 4 includes an adhesive layer 401 provided on the outer side of the steel pipe base 1. A wear-resistant layer 402 is provided on the outer side of the adhesive layer 401. Reinforcing blocks 403 are uniformly provided on the outer wall of the wear-resistant layer 402. The wear-resistant layer 402 is an alumina layer. The reinforcing blocks 403 are distributed at equal intervals on the outer wall of the wear-resistant layer 402.

[0030] In order to prevent wear on the outer wall of the composite steel pipe during operation and use, which would affect the overall performance of the steel pipe, a protective structure 4 is set up. A wear-resistant layer 402 is bonded to the outer wall of the steel pipe base 1 through an adhesive layer 401. The wear-resistant layer 402 is an aluminum oxide layer, which increases the wear resistance of the steel pipe and prevents wear on the inner wall material. Reinforcing blocks 403 are uniformly fixed on the outer wall of the wear-resistant layer 402, which increases the overall strength of the device and prevents damage to the steel pipe from impacts, thus greatly increasing the practicality of the device.
