Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe technology, specifically to a wear-resistant reinforced stainless steel pipe. Background Technology

[0002] Stainless steel pipe is a tubular material made of stainless steel. It possesses characteristics such as corrosion resistance, high strength, aesthetically pleasing surface, and ease of cleaning and maintenance. Its main components include elements such as iron, chromium, and nickel. Chromium imparts corrosion resistance, while nickel enhances toughness and processing performance. Based on manufacturing processes, it can be divided into seamless steel pipes (made through piercing and hot rolling, resulting in uniform wall thickness and high strength) and welded steel pipes (made by rolling and welding steel plates, offering lower cost and diverse specifications). Based on applications, it can be divided into industrial pipes (such as those used in chemical, petroleum, and machinery manufacturing fields) and civil pipes (such as those used in building decoration, kitchenware, and medical equipment). Due to its excellent comprehensive performance, stainless steel pipe is widely used in aerospace, marine engineering, food processing, and other scenarios requiring high corrosion resistance and stability. Existing stainless steel pipes are prone to surface wear due to long-term contact and friction with external objects during use, and are also susceptible to deformation under stress. Therefore, we propose a wear-resistant reinforced stainless steel pipe. Utility Model Content

[0003] The purpose of this utility model is to provide a wear-resistant reinforced stainless steel pipe, which has the advantages of improving the strength and wear resistance of stainless steel pipe, effectively avoiding surface wear and deformation of stainless steel pipe during long-term use, and solving the problem that the outer surface of existing stainless steel pipe is easily worn due to long-term contact and friction with external objects, and is also prone to deformation under stress.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a wear-resistant reinforced stainless steel pipe, comprising a stainless steel pipe body, wherein a plurality of first grooves are arranged in a ring array at equal intervals on the outer surface of the stainless steel pipe body, and a raised rib is formed on the inner wall of the stainless steel pipe body at each of the first grooves; a fixing ring is connected to both ends of the stainless steel pipe body; a wear-resistant rubber strip is provided inside each of the first grooves, and the two ends of the wear-resistant rubber strip are respectively connected to the inner sides of the two fixing rings.

[0005] Preferably, the outer surface of the stainless steel pipe body is provided with a wear-resistant coating. The wear-resistant coating can improve the wear resistance of the stainless steel pipe body surface and effectively prevent wear on the stainless steel pipe body surface in areas not protected by the wear-resistant rubber strip.

[0006] Preferably, the inner wall of the stainless steel pipe body is provided with an inner lining, and a second groove is provided on the outer surface of the inner lining at each position of the raised rib, and the raised rib is located inside the second groove. The material of the inner lining is plastic or ceramic, etc., to make up for the performance shortcomings of the stainless steel pipe itself, or to give the stainless steel pipe specific functions to adapt to complex working conditions, such as corrosion resistance and wear resistance. The raised rib and the second groove play a role in limiting and fixing the inner lining.

[0007] Preferably, each of the wear-resistant rubber strips has a cavity inside, which can reduce the weight of the wear-resistant rubber strip and improve its cushioning performance, thereby providing better cushioning protection for the stainless steel pipe body that is impacted.

[0008] Preferably, each of the fixing rings has a stepped hole near the end of each wear-resistant rubber strip on its outer side. Each wear-resistant rubber strip has a screw connected to both ends, and the screw passes through the stepped hole. Each screw has a nut fitted on its outer surface, and the nut is located inside the stepped hole. The two ends of the wear-resistant rubber strip are fixed by the nut, screw, and stepped hole, which facilitates the disassembly and assembly of the wear-resistant rubber strip, and thus facilitates the replacement of worn or damaged wear-resistant rubber strips.

[0009] Preferably, each of the fixing rings has a plurality of bolt holes arranged in a ring array at equal intervals on its outer side.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model, by setting a stainless steel pipe body, a first groove, raised ribs, a fixing ring, and a wear-resistant rubber strip, achieves the effect of improving the strength and wear resistance of the stainless steel pipe, effectively preventing surface wear and deformation of the stainless steel pipe during long-term use. The first groove forms raised ribs on the inner wall of the stainless steel pipe body, which improves the structural strength of the stainless steel pipe body and effectively prevents the stainless steel pipe body from deforming when subjected to external force. At the same time, the first groove plays a limiting role for the wear-resistant rubber strip. When a foreign object comes into contact with the stainless steel pipe body, it will first contact the wear-resistant rubber strip, thereby effectively preventing surface wear of the stainless steel pipe body. Meanwhile, the wear-resistant rubber strip can provide cushioning protection for the stainless steel pipe body that is impacted.

[0012] 2. This utility model, by incorporating stepped holes, screws, and nuts, facilitates the replacement of worn or damaged wear-resistant rubber strips. During installation, both ends of the wear-resistant rubber strip are inserted into the stepped holes on the two fixing rings, and the strip is positioned within the first groove. The screws at both ends of the strip are secured with nuts, thus fixing the strip in place. The cavity design reduces the weight of the wear-resistant rubber strip while improving its cushioning performance, thereby providing better cushioning protection for the stainless steel pipe body subjected to impact.

Detailed Implementation

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] like Figure 1 , Figure 3 and Figure 4 As shown, this utility model proposes a wear-resistant reinforced stainless steel pipe, comprising a stainless steel pipe body 2. The outer surface of the stainless steel pipe body 2 is provided with a plurality of first grooves 7 arranged in a ring array at equal intervals. A raised rib 8 is formed on the inner wall of the stainless steel pipe body 2 at the position of each first groove 7. A fixing ring 1 is connected to both ends of the stainless steel pipe body 2. A wear-resistant rubber strip 3 is provided inside each first groove 7, and both ends of the wear-resistant rubber strip 3 are respectively connected to the inner sides of two fixing rings 1. Part of the wear-resistant rubber strip 3 is located outside the first groove 7. The first groove 7 serves to limit the wear-resistant rubber strip 3, preventing contact between foreign objects and the outer surface of the stainless steel pipe body 2, thereby effectively avoiding wear on the outer surface of the stainless steel pipe body 2. A wear-resistant coating 4 is provided on the outer surface of the stainless steel pipe body 2, which can improve the wear resistance of the surface of the stainless steel pipe body 2. In areas not protected by the wear-resistant rubber strip 3, wear on the surface of the stainless steel pipe body 2 can be effectively prevented.

[0020] The inner wall of the stainless steel pipe body 2 is provided with an inner liner 9, which is made of plastic or ceramic, etc., to compensate for the performance shortcomings of the stainless steel pipe itself, or to give the stainless steel pipe specific functions to meet the needs of complex working conditions, such as corrosion resistance and wear resistance. The outer surface of the inner liner 9 is provided with a second groove 10 at each position of the raised rib 8, and the raised rib 8 is located inside the second groove 10. The raised rib 8 and the second groove 10 play a role in limiting and fixing the inner liner 9. Each fixing ring 1 has several bolt holes 5 evenly spaced in a ring array on its outer side. When the stainless steel pipe bodies 2 are connected, after the fixing rings 1 on the two stainless steel pipe bodies 2 are mated, the bolts pass through the bolt holes 5. Each wear-resistant rubber strip 3 is provided with a cavity 12 inside. The cavity 12 can reduce the weight of the wear-resistant rubber strip 3 and also improve the cushioning performance of the wear-resistant rubber strip 3, thereby providing better cushioning protection for the stainless steel pipe body 2 that is impacted.

[0021] In this embodiment, the first groove 7 forms raised ribs 8 on the inner wall of the stainless steel pipe body 2, which improves the structural strength of the stainless steel pipe body 2 and effectively prevents the stainless steel pipe body 2 from deforming when subjected to external force. At the same time, the first groove 7 plays a limiting role for the wear-resistant rubber strip 3. When a foreign object comes into contact with the stainless steel pipe body 2, it will first come into contact with the wear-resistant rubber strip 3, thereby effectively preventing surface wear of the stainless steel pipe body 2. Meanwhile, the wear-resistant rubber strip 3 can provide buffer protection for the stainless steel pipe body 2 that is impacted.

[0022] Example 2

[0023] like Figures 1-4 As shown, the wear-resistant reinforced stainless steel pipe proposed in this utility model, compared with the first embodiment, further includes a stepped hole 6 provided on the outer side of each fixing ring 1 near the end of each wear-resistant rubber strip 3, and a screw 11 connected to both ends of each wear-resistant rubber strip 3, with the screw 11 passing through the stepped hole 6. A nut 13 is sleeved on the outer surface of each screw 11, and the nut 13 is located inside the stepped hole 6.

[0024] In this embodiment, when installing the wear-resistant rubber strip 3, both ends of the wear-resistant rubber strip 3 are inserted into the stepped holes 6 on the two fixing rings 1, and the wear-resistant rubber strip 3 is placed inside the first groove 7. The screws 11 at both ends of the wear-resistant rubber strip 3 are fixed by nuts 13, thus fixing the wear-resistant rubber strip 3 in place, which facilitates the replacement of worn or damaged wear-resistant rubber strip 3. The above specific embodiments are only a few preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
