[0003] The steel pipes currently in use are cylindrical steel pipes. When encountering external or internal pressure shocks, the steel pipes will be deformed or damaged due to the pressure. Therefore, the current steel pipes still need to be improved. Utility Model Content

[0004] In order to reduce the deformation or damage of seamless stainless steel pipes due to pressure when encountering external or internal pressure shocks and improve the pressure resistance of seamless stainless steel pipes, the present application provides a pressure-resistant seamless stainless steel pipe.

[0005] The present application provides a compression-resistant seamless stainless steel pipe adopts the following technical solution:

[0006] A pressure-resistant seamless stainless steel pipe comprises a steel pipe body, wherein the steel pipe body comprises an inner layer and an outer layer, a pressure-resistant layer is arranged between the inner layer and the outer layer, the pressure-resistant layer comprises a deformable buffer plate fixed on the inner layer at circumferential intervals, and a plurality of buffer grooves are arranged at intervals on the buffer plate.

[0007] By adopting the above technical scheme, the deformable buffer plate can buffer the pressure exerted on the stainless steel pipe. The buffer plates are arranged at intervals so that there is space for deformation between adjacent buffer plates. The buffer groove provides space for the buffer plate to deform under force, thereby improving the compressive buffering effect of the steel pipe. When encountering external or internal pressure shocks, the deformation or damage of the seamless stainless steel pipe due to pressure is reduced, thereby improving the compressive performance of the seamless stainless steel pipe.

[0008] Preferably, the pressure-resistant layer further comprises a reinforcing plate fixed to the side of the buffer plate close to the inner layer, a plurality of reinforcing plates are arranged at intervals in the buffer plate, and the reinforcing plates are located between adjacent buffer grooves and are connected to each other.

[0009] By adopting the above technical solution, the buffer groove provides deformation buffering capability, and the reinforcing plate provides high-strength supporting force, thereby improving the compressive resistance of the stainless steel pipe from two aspects, achieving better results.

[0010] Preferably, the reinforcing plate comprises relative stabilizing plates and supporting plates, the supporting plates are fixed between the relative stabilizing plates, and the lower portions of the relative stabilizing plates close to the inner layer are inclined in opposite directions.

[0011] By adopting the above technical solution, the two inclined opposite stabilizing plates can play a stable supporting role in the buffer plate, and while the buffer groove is buffering, further provide a stronger supporting force to improve the compressive performance of the stainless steel pipe.

[0012] Preferably, the support plate is horizontally fixed to the upper part of the relative stabilizing plate, and the thickness of the support plate is greater than the thickness of the stabilizing plate.

[0013] By adopting the above technical solution, the support plate located on the upper part of the stabilizing plate has a greater thickness, which can increase the supporting force to withstand greater pressure.

[0014] Preferably, the buffer groove is triangular in shape, and the opening of the triangle faces the direction close to the outer layer.

[0015] By adopting the above technical solution, the open triangular buffer groove can also provide deformation space when subjected to pressure.

[0016] Preferably, the pressure-resistant layer further comprises a deformable T-shaped plate fixed between the spaced buffer plates, and the upper surface of the T-shaped plate is flush with the upper surface of the buffer plate.

[0017] By adopting the above technical solution, the T-shaped plates are filled between adjacent deformable buffer plates to improve the supporting force and compression resistance.

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

[0019] The deformable buffer plate can buffer the pressure on the stainless steel pipe. The buffer plates are arranged at intervals so that there is space for deformation between adjacent buffer plates. The buffer groove provides space for the buffer plate to deform under stress, thereby improving the compression buffering effect of the steel pipe. When encountering external or internal pressure shocks, the seamless stainless steel pipe is less likely to be deformed or damaged due to pressure, thereby improving the compression resistance of the seamless stainless steel pipe.

[0020] The buffer groove provides deformation buffering capacity, and the reinforcing plate provides high-strength supporting force, which improves the compressive resistance of the stainless steel pipe from two aspects, with better effect; the two inclined opposite stabilizing plates play a stable supporting role, and the supporting plate located on the upper part of the stabilizing plate is thicker, which can increase the supporting force to withstand greater pressure and improve the compressive performance of the stainless steel pipe;

[0025] The present application is further described in detail below in conjunction with the accompanying drawings.

[0026] The present application discloses a compression-resistant seamless stainless steel pipe. Figure 1 , including a steel pipe body 1, the steel pipe body 1 includes an inner layer 11 and an outer layer 12, and a pressure-resistant layer 2 is arranged between the inner layer 11 and the outer layer 12. Through the arrangement of the pressure-resistant layer 2, when encountering external or internal pressure shock, the deformation or damage of the seamless stainless steel pipe due to pressure is reduced, thereby improving the pressure resistance of the seamless stainless steel pipe.

[0027] Reference Figure 1 The pressure-resistant layer 2 includes deformable buffer plates 21 fixed on the inner layer 11 at circumferential intervals. The deformable buffer plates 21 can buffer the pressure exerted on the stainless steel pipe. The buffer plates 21 are arranged at intervals so that there is a deformation space between adjacent buffer plates 21.

[0028] Reference Figure 1 The pressure-resistant layer 2 also includes a deformable T-shaped plate 22 fixed between the spaced buffer plates 21, and the upper surface of the T-shaped plate 22 is flush with the upper surface of the buffer plate 21; the supporting force and pressure resistance are improved by filling the T-shaped plate 22.

[0029] Reference Figure 1 A plurality of buffer grooves 211 are spaced apart on the buffer plate 21. The buffer grooves 211 are triangular in shape, and the openings of the triangles face the direction close to the outer layer 12. When subjected to pressure, the open triangular buffer grooves 211 can also provide deformation space, thereby improving the compression buffering effect of the steel pipe.

[0030] Reference Figure 1 The pressure-resistant layer 2 further includes a reinforcing plate 23 fixed to the side of the buffer plate 21 close to the inner layer 11 , and a plurality of reinforcing plates 23 are arranged at intervals in the buffer plate 21 , and the reinforcing plates 23 are located between adjacent buffer grooves 211 and are connected to each other.

[0031] Reference Figure 1 The reinforcing plate 23 includes a relative stabilizing plate 231, which is inclined in opposite directions near the lower part of the inner layer 11. The two inclined relative stabilizing plates 231 can play a stable supporting role in the buffer plate 21. While the buffer groove 211 is buffering, it further provides a stronger supporting force to improve the compressive performance of the stainless steel pipe.

[0032] Reference Figure 1 The reinforcing plate 23 also includes a supporting plate 232, which is horizontally fixed to the upper part of the relative stabilizing plate 231, and the thickness of the supporting plate 232 is greater than that of the stabilizing plate 231. The supporting plate 232 located on the upper part of the stabilizing plate 231 is thicker, which can increase the supporting force to withstand greater pressure.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
