Description

Technical Field

[0001] The utility model belongs to the technical field of welded pipes, in particular to a high-strength welded pipe. Background Art

[0002] With the development of science and technology, welding technology has gradually matured. In terms of welded steel pipes, it refers to steel pipes with seams on the surface that are formed by bending steel strips or steel plates into round, square and other shapes and then welding them. However, due to the low strength of welded steel pipes, they are easily damaged during use, so a high-strength welded pipe is needed.

[0003] A Chinese patent application with publication number CN219432658U discloses a high-strength welded pipe, comprising a first welded pipe body, a second welded pipe body, a pipe body, a first reinforcement layer and an arc block, wherein the second welded pipe body is arranged below the first welded pipe body, the inner wall of the pipe body is provided with a first reinforcement layer, a plug block is arranged at the bottom of the first welded pipe body, a slot is provided at the contact position between the plug block and the second welded pipe body, an arc block is arranged outside the connection between the first welded pipe body and the second welded pipe body, and a locking nut is arranged on the limiting screw. The utility model, through the setting of the plug block and the slot, aligns the plug block on the first welded pipe body with the slot position on the second welded pipe body for clamping connection, then wraps the connection between the first welded pipe body and the second welded pipe body through the arc block, and finally locks and fixes through the limiting screw and the locking nut, thereby ensuring the stability of the connection between the first welded pipe body and the second welded pipe body.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. The above-mentioned high-strength welded pipe has poor anti-deformation ability and is prone to deformation when under pressure;

[0006] 2. The above-mentioned high-strength welded pipe only has its strength enhanced by the first reinforcement layer and the second reinforcement layer, which results in insufficient strength performance.

[0007] To this end, we provide a high-strength welded pipe to solve the above problems. Utility Model Content

[0008] The utility model aims to provide a high-strength welded pipe, which can enhance the strength of the inner pipe of the welded pipe by a reinforcing component to avoid deformation, and can protect the inner pipe of the welded pipe by a protective component to avoid deformation of the inner pipe of the welded pipe caused by external force, thereby solving the problem of poor anti-deformation ability of existing high-strength welded pipes.

[0009] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0010] The utility model discloses a high-strength welded pipe, comprising a welded pipe inner pipe and a connecting layer, the outer side wall of the welded pipe inner pipe is provided with the connecting layer, the outer side wall of the welded pipe inner pipe is installed with a protective component, the outer side wall of the connecting layer is installed with a reinforcing component, and the inner side wall of the connecting layer is installed with a protective component; the inner side wall of the wear-resistant layer of the reinforcing component is installed with an outer pipe, the inner side wall of the outer pipe is installed with an anti-corrosion layer, the inner side wall of the anti-corrosion layer is installed with a reinforcing layer, and the inner side wall of the reinforcing layer is installed with high-strength low-alloy steel; the surface of the buffer layer of the protective component is installed with a shock-absorbing rubber column, the outer side of the shock-absorbing rubber column is provided with a fixing block, and the fixing block is installed on the surface of the buffer layer.

[0011] The utility model is further configured that a buffer layer is installed on the outer side wall of the inner tube of the welded pipe, and the outer side wall of the inner tube of the welded pipe is fitted and connected to the buffer layer.

[0012] The utility model is further configured that the upper side wall of the buffer layer is fitted and connected with the shock-absorbing rubber column, and the upper surface of the buffer layer is fixedly connected with the fixing block.

[0013] The utility model is further configured such that the outer side wall of the shock-absorbing rubber column is fitted and connected to the fixing block, and the upper side wall of the shock-absorbing rubber column is fitted and connected to the connecting layer.

[0014] The utility model is further configured that the outer side wall of the connection layer is provided with high-strength low-alloy steel, and the outer side wall of the connection layer is fitted and connected to the high-strength low-alloy steel.

[0015] The utility model is further configured such that the outer side wall of the high-strength low-alloy steel is bonded and connected to the reinforcement layer, and the outer side wall of the reinforcement layer is bonded and connected to the anti-corrosion layer.

[0016] The utility model is further configured such that the outer side wall of the anti-corrosion layer is fitted and connected to the outer tube, and the outer side wall of the outer tube is fitted and connected to the wear-resistant layer.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model sets a reinforcing component and protects the surface of the outer tube through the wear-resistant layer to avoid the outer tube surface being damaged by friction and affecting the appearance. The outer tube can protect the inner tube of the welded tube and play a certain role in strengthening the strength. The anti-corrosion layer can prevent the inner tube of the welded tube from being corroded, thereby increasing the service life. At the same time, the reinforcing layer and high-strength low-alloy steel both play a role in strengthening the strength, making the strength effect of the inner tube of the welded tube better. High-strength low-alloy steel can also meet the requirements of reducing the dead weight of the structure, improving reliability and saving materials and resources, solving the problem of insufficient strength performance caused by only strengthening the strength of the welded tube through the first and second reinforcing layers.

[0019] 2. The utility model sets a protective component. When the inner tube of the welded pipe is squeezed and collided by external force, the squeezing force and the collision force will first contact the shock-absorbing rubber column. The shock-absorbing rubber column plays a role in absorbing and absorbing vibrations and can relieve the force. The fixed block on the outside of the shock-absorbing rubber column fixes the shock-absorbing rubber column so that the shock-absorbing rubber column can have a better buffering effect. The shock-absorbing rubber column transfers the force to the buffer layer, and the buffer layer relieves the force, thereby preventing the squeezing force and the collision force from affecting the inner tube of the welded pipe and causing deformation. This solves the problem of poor anti-deformation ability and easy deformation of the welded pipe when under pressure.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
