[0002] High-gloss high-performance composite stainless steel pipe is a composite pipe with excellent finish and high performance. This pipe combines the corrosion resistance of stainless steel with the advantages of other metal materials, such as the strength of carbon steel, to form a pipeline material with excellent performance.

[0003] However, the existing stainless steel pipes are prone to collapse when subjected to external pressure, thereby affecting the delivery of the medium.

[0004] Therefore, it is very necessary to invent a high-gloss and high-performance composite stainless steel pipe. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a high-gloss and high-performance composite stainless steel pipe, comprising an outer pipe, a middle pipe and an inner pipe, wherein the middle pipe is fixedly installed inside the outer pipe, and the inner pipe is fixedly installed inside the middle pipe; a plurality of elastic corrugated plates are evenly distributed and fixedly installed on the outer surface of the inner pipe, and the elastic corrugated plates are in the middle pipe, and the elastic corrugated plates are fixedly connected to the middle pipe.

[0006] Preferably, a plurality of annular grooves are evenly distributed on the outer surface of the middle tube, and a plurality of slot holes are evenly distributed from one end to the other end of the middle tube, and the slot holes are connected to the annular grooves.

[0007] Preferably, a plurality of cavities are formed between the elastic corrugated plate and the middle tube and the inner tube.

[0008] Preferably, the inner and outer surfaces of the outer tube, the middle tube, the inner tube and the elastic corrugated plate are coated with an anti-corrosion coating.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The overall arrangement of the utility model can have multiple buffering and pressure resistance capabilities when subjected to external pressure, preventing the inner tube from being directly crushed, thereby making the overall structure safer and more reliable during use.

[0017] Example:

[0018] As attached Figure 1 To Attachment Figure 2 As shown:

[0019] The utility model provides a high-gloss and high-performance composite stainless steel pipe, comprising an outer pipe 1, a middle pipe 2 and an inner pipe 5. The middle pipe 2 is fixedly installed inside the outer pipe 1, and the middle pipe 2 can be protected by the arrangement of the outer pipe 1, and the inner pipe 5 is fixedly installed inside the middle pipe 2, and the inner pipe 5 can be protected by the arrangement of the middle pipe 2; a plurality of elastic corrugated plates 6 are evenly and fixedly installed on the outer surface of the inner pipe 5, and a medium can be transported by the arrangement of the inner pipe 5, and the elastic corrugated plates 6 are in the middle pipe 2. By the arrangement of the elastic corrugated plates 6, when the outer pipe 1 and the middle pipe 2 are subjected to pressure, the pressure can be resisted and the inner pipe 5 has a certain deformation ability, thereby preventing the pressure from directly acting on the inner pipe 5, and the elastic corrugated plates 6 are fixedly connected to the middle pipe 2.

[0020] The outer surface of the middle tube 2 is evenly provided with a plurality of annular grooves 3. Through the provision of the annular grooves 3, when the outer tube 1 is subjected to external pressure, the outer tube 1 at the annular grooves 3 can have a certain deformation ability, and a plurality of slot holes 4 are evenly provided from one end to the other end of the middle tube 2. Through the provision of the slot holes 4, when the outer tube 1 at the slot holes 4 is subjected to pressure, the middle tube 2 can have a certain buffering and deformation ability, and the slot holes 4 are connected to the annular grooves 3.

[0021] A plurality of cavities 7 are formed between the elastic corrugated plate 6 and the middle tube 2 and the inner tube 5. The arrangement of the cavities 7 can provide a certain deformation space for the elastic corrugated plate 6 when the elastic corrugated plate 6 is subjected to pressure.

[0022] The inner and outer surfaces of the outer tube 1, the middle tube 2, the inner tube 5 and the elastic corrugated plate 6 are coated with an anti-corrosion coating. The anti-corrosion coating adopts existing technology, such as metal coatings, organic coatings, composite coatings and functional coatings in the existing technology, so it will not be described in detail here.
