Description

Technical Field

[0001] The utility model relates to the field of high-strength steel pipes, in particular to a new type of high-strength steel pipe. Background Art

[0002] Steel pipe is a metal material made of steel with a hollow cross-section and a length much larger than the outer diameter. Steel pipe is a hollow long steel strip. Its cross-section is usually round, but it can also be flat, square and special-shaped. The two ends of the steel pipe are open and have a closed hollow section. The ratio of length to cross-sectional circumference is relatively large. Due to its closed hollow section, steel pipe is suitable as a transportation pipeline for liquids, gases and some solids such as coal gas and steam. Under the same weight, structural parts and components made of steel pipe have a larger section modulus than solid parts. New high-strength steel pipes may use more advanced materials science and manufacturing technologies to improve their performance, such as higher strength to toughness ratio, better corrosion resistance, lighter weight or better welding performance.

[0003] According to the Chinese patent with publication number: CN210440959U, a new type of anti-slip high-strength alloy steel pipe. The technical solution adopted by the utility model is: including a cylindrical alloy steel pipe main structure, cylindrical reinforcement support stabilization assembly connection columns are respectively provided on the left and right sides of the outer cylindrical surface of the alloy steel pipe main structure, and left and right symmetrical conical assembly guide installation fastening anti-loosening connection stabilization columns are respectively provided on the left and right sides of the reinforcement support stabilization assembly connection columns on the outer cylindrical surface of the alloy steel pipe main structure, and the diameter of the connection position of the assembly guide installation fastening anti-loosening connection stabilization column and the reinforcement support stabilization assembly connection column is the same as the diameter of the reinforcement support stabilization assembly connection column. The advantages of the utility model are: it can have stronger performance when in use, can be more firmly connected to the assembly position when installed, so that the connection strength of the installation position is better, and can improve the safety of the alloy steel pipe as a whole during use.

[0004] In the above scheme, cylindrical reinforcement support stabilization assembly connecting columns are respectively provided on the left and right sides of the outer cylindrical surface of the alloy steel pipe main structure, and left and right symmetrical conical assembly guide installation fastening and anti-loosening connection stabilization columns are respectively provided on the left and right sides of the outer cylindrical surface of the alloy steel pipe main structure. As a result, it has the following disadvantages: the outer surface of the existing steel pipe is easily concave and twisted due to extrusion, which reduces its practicality. The staff has to spend a lot of time to repair it, which is time-consuming and labor-intensive, and the operation is cumbersome, which reduces the overall strength of the pipe body and increases the cost. Utility Model Content

[0005] The purpose of the utility model is to provide a new type of high-strength steel pipe to solve the problem that the outer surface of the existing steel pipe is easily dented and twisted due to extrusion, which reduces the practicality and requires workers to spend a lot of time to repair it.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical solutions: a new type of high-strength steel pipe, including an inner tube body and an outer tube body, the outer tube body is sleeved on the outside of the inner tube body, the outer wall of the inner tube body is installed with a number of elastic columns distributed around it, and a restorable inner core bone is installed on the outside of the elastic column, the elastic columns are all arranged between the inner tube body and the outer tube body, the restorable inner core bone is arranged between the inner tube body and the outer tube body, and the elastic column is arranged inside the restorable inner core bone.

[0007] Preferably, a waterproof ring is provided between the inner tube body and the outer tube body, and the waterproof ring is provided outside a plurality of elastic columns distributed in an annular manner.

[0008] Preferably, an inner core bone is fixedly provided inside the elastic column, and the inner core bone is made of steel material.

[0009] Preferably, the outer surface of the outer tube is provided with a plurality of anti-slip grooves.

[0010] Preferably, the inner wall of the inner tube body is coated with an anti-rust coating, and the anti-rust coating adopts zinc yellow anti-rust paint.

[0011] Preferably, the outer wall of the outer tube body is coated with a wear-resistant coating, and the wear-resistant coating is an epoxy resin coating.

[0012] Compared with the existing technology, the new high-strength steel pipe adopting the above technical solution has the following beneficial effects:

[0013] 1. During use, when the outer wall of the outer tube is squeezed, the elastic column is squeezed inward under the action of the force. When the external squeezing force is gone, the elastic column recovers and resists the pressure outward, thereby realizing the anti-squeezing effect of the steel pipe and enhancing the practicality and flexibility of the steel pipe. Then, under the action of the restored inner core bone, the anti-squeezing effect of the outer wall of the outer tube is increased, thereby improving the overall strength of the steel pipe. Then, the inner core bone improves the stability during use, and the waterproof ring strengthens the overall waterproof ability of the steel pipe and improves the quality of the steel pipe.

[0019] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] like Figures 1-4 As shown, a new type of high-strength steel pipe includes an inner tube body 1 and an outer tube body 6. The outer tube body 6 is sleeved on the outside of the inner tube body 1. The outer wall of the inner tube body 1 is installed with several elastic columns 2 distributed around it. The outside of the elastic column 2 is installed with a recovery inner core bone 5. The elastic columns 2 are all arranged between the inner tube body 1 and the outer tube body 6. The recovery inner core bone 5 is arranged between the inner tube body 1 and the outer tube body 6. The elastic column 2 is arranged inside the recovery inner core bone 5. A waterproof ring 4 is arranged between the inner tube body 1 and the outer tube body 6. The waterproof ring 4 is sleeved on the outside of several annularly distributed elastic columns 2. The inside of the elastic column 2 is fixedly penetrated with an inner core bone 3. The inner core bone 3 adopts an inner core made of steel material. The inner wall of the inner tube body 1 is coated with an anti-rust coating, and the anti-rust coating adopts zinc yellow anti-rust paint. The outer wall of the outer tube body 6 is coated with a wear-resistant coating, and the wear-resistant coating adopts epoxy resin coating.

[0021] During use, when the outer wall of the outer tube body 6 is squeezed, the elastic column 2 is squeezed inward under the action of the force. When the external squeezing force is gone, the elastic column 2 recovers and resists the pressure outward, thereby realizing the anti-squeezing effect of the steel pipe and enhancing the practicality and flexibility of the steel pipe. Then, under the action of the restored inner core bone 5, the anti-squeezing effect of the outer wall of the outer tube body 6 is increased, and the overall strength of the steel pipe is improved. Then, the inner core bone 3 improves the stability during use, and the waterproof ring 4 strengthens the overall waterproof ability of the steel pipe and improves the quality of the steel pipe.
