Description

Technical Field

[0001] The present invention relates to the technical field of steel pipes, and more particularly to a high-durability steel pipe for engineering. Background Art

[0002] Steel pipe is a hollow long strip of steel. According to the different production processes and uses, it can be divided into two categories: seamless steel pipe and welded steel pipe. Seamless steel pipe is made by perforating a whole round steel and has no welds on the surface, while welded steel pipe is made by bending steel plates or steel strips into shape and then welding them.

[0003] Although the steel pipes in the prior art can be used normally, they still have many disadvantages in actual use. For example, the compression resistance of the steel pipes in the prior art is not good enough. When they are squeezed by heavy objects, they may be flattened. This leads to the durability of the steel pipes in the prior art being not good enough, which is not conducive to promotion and use. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a high-durability steel pipe for engineering. By providing steel strands and a triangular inner fixed frame, the present invention has a better compressive resistance effect. When encountering heavy objects, the present invention can effectively avoid the problem of being flattened and can maintain its own shape, thereby improving the durability of the present invention and facilitating its promotion and use, so as to solve the problems raised in the above-mentioned background technology.

[0006] In a preferred embodiment, the pipe body is made of carbon steel material.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] As attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, the present invention provides a high-durability steel pipe for engineering, including a pipe body 1, an inner lining layer 2 is welded on the inner wall of the pipe body 1, steel strands 3 are arranged inside the inner lining layer 2, the number of the steel strands 3 is set to three, the shape of the steel strands 3 is set to be threaded, and a plurality of triangular inner fixing frames 4 are welded inside the inner lining layer 2, and the three corners of the triangular inner fixing frames 4 are respectively welded to three steel strands 3, and the plurality of triangular inner fixing frames are equidistantly arranged along the steel strands 3 inside the inner lining layer 2, and the three steel strands 3 are evenly distributed in a ring shape inside the inner lining layer 2.

[0020] The pipe body 1 is made of carbon steel material.

[0021] The inner lining layer 2 is made of alloy steel material.

[0022] The thickness of the tube body 1 is set to 4 mm.

[0025] The three steel strands 3 are all made of alloy steel material.

[0026] The plurality of triangular inner fixing frames 4 are all made of alloy steel material.

[0027] The specific implementation method is as follows: when using the present invention, multiple triangular internal fixing frames 4 cooperate with three steel strands 3 to form a spiral combination structure composed of triangular structures inside the steel pipe. This structure combines multiple triangles together, so that the multiple triangular internal fixing frames 4 form a whole, and the steel pipe is made into a whole from the inside, which significantly improves the compression resistance of the steel pipe. When a heavy object is pressed on the steel pipe, the steel pipe is difficult to deform, thereby improving the durability of the steel pipe. This makes the compression resistance of the present invention better. When encountering heavy object squeezing, the present invention can effectively avoid the problem of being flattened and can maintain its own shape, thereby improving the durability of the present invention and facilitating promotion and use.
