Description

Technical Field

[0001] This application relates to the technical field of stainless steel pipes, especially high-strength small-diameter stainless steel pipes. Background Art

[0002] When a steel pipe bears a radial load perpendicular to the extending direction of the steel pipe, its elastic activity performance is poor. When the radial load suddenly increases, it is prone to problems of rupture and damage due to the impact of the load, which limits the application range of the steel pipe.

[0003] In view of the above related technologies, the applicant believes that the ability of the current stainless steel pipe to bear radial loads still needs to be improved. Utility Model Content

[0004] In order to enable the stainless steel pipe to better bear radial loads, thereby reducing the problem of rupture and damage and improving the application range, this application provides a high-strength small-diameter stainless steel pipe.

[0005] The high-strength small-diameter stainless steel pipe provided by this application adopts the following technical solutions:

[0006] The high-strength small-diameter stainless steel pipe includes a steel pipe main body. A reinforcing layer is provided on the outer side wall of the steel pipe main body. The reinforcing layer includes cross reinforcing plates and deformable compression-resistant blocks. The compression-resistant blocks are arranged circumferentially at intervals on the outer side of the reinforcing layer, and the cross reinforcing plates are fixedly arranged at intervals on the inner side of the reinforcing layer.

[0007] By adopting the above technical solutions, the cross reinforcing plates increase the structural strength, and the compression-resistant blocks improve the deformation ability against impact. Through the synergistic effect of the two, the stainless steel pipe can better bear radial loads, thereby reducing the problem of rupture and damage and improving the application range.

[0008] Preferably, the reinforcing layer further includes deformable buffer blocks. The buffer blocks are fixedly arranged at intervals on the inner side of the reinforcing layer, and the buffer blocks and the cross reinforcing plates are arranged alternately. The two ends of the cross reinforcing plates are respectively fixedly arranged at the two ends of the compression-resistant blocks.

[0009] By adopting the above technical solutions, the buffer blocks play a role in shock absorption and buffering on the inner side of the reinforcing layer, and cooperate with the compression-resistant blocks on the outer side to jointly enhance the reinforcing layer's effect on the steel pipe main body.

[0010] Preferably, the cross sections of the compression-resistant blocks and the buffer blocks are both trapezoidal, and the lower bases of the compression-resistant blocks face the outer side of the reinforcing layer, while the lower bases of the buffer blocks face the inner side of the reinforcing layer.

[0011] By adopting the above technical solutions, the longer lower bases of the compression-resistant blocks and the buffer blocks face the outer side and the inner side of the reinforcing layer respectively, increasing the force-receiving surface on the outer side and the deformation surface on the inner side, enhancing the ability to receive impact and improving the strength of the steel pipe main body.

[0012] Preferably, the compression block and the buffer block are in contact with each other.

[0013] By adopting the above technical solution, the buffer blocks on the inner and outer sides and the compression block play a synergistic role in enhancing the strength of the main body of the reinforced steel pipe.

[0014] Preferably, arc-shaped protrusions are fixedly provided on the side walls where the compression block and the buffer block are in contact, and the arc-shaped protrusions on the compression block and the arc-shaped protrusions on the buffer block are arranged in a staggered manner and are in contact with each other.

[0015] By adopting the above technical solution, the deformation space between adjacent arc-shaped protrusions is increased, and buffering is carried out through sufficient deformation under pressure and the compressive capacity is improved.

[0016] Preferably, a reinforcing rib is vertically fixed in the middle of the cross reinforcing plate.

[0017] By adopting the above technical solution, on the one hand, the structural strength of the cross reinforcing plate is enhanced; on the other hand, it cooperates with the cross reinforcing plate to improve the supporting force for the stainless steel pipe, thereby improving the overall strength of the stainless steel pipe.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

[0019] The cross reinforcing plate increases the structural strength, and the compression block improves the deformation ability against impact. Through the synergistic effect of the two, the stainless steel pipe can better withstand the radial load, thereby reducing the problem of fracture damage and improving the scope of application;

[0020] The buffer block plays a shock absorption and buffering role on the inner side of the reinforcing layer. The longer lower bases of the compression block and the buffer block face the outer side and the inner side of the reinforcing layer respectively, increasing the force receiving surface on the outer side and the deformation surface on the inner side, and having a stronger ability to receive impacts, thereby improving the strength of the main body of the steel pipe; the setting of the arc-shaped protrusions increases the deformation space between adjacent arc-shaped protrusions, and buffering is carried out through sufficient deformation under pressure and the compressive capacity is improved

[0021] The reinforcing rib vertically fixed in the middle of the cross reinforcing plate, on the one hand, enhances the structural strength of the cross reinforcing plate; on the other hand, it cooperates with the cross reinforcing plate to improve the supporting force for the stainless steel pipe, thereby improving the overall strength of the stainless steel pipe.
