Description

Technical Field

[0001] This application relates to the technical field of stainless steel pipes, and in particular to a wear-resistant and bending-resistant stainless steel pipe. Background Technology

[0002] Stainless steel pipe is a hollow, long, round steel material, mainly used in industrial pipelines for petroleum, chemical, medical, food, light industry, and machinery, as well as mechanical structural components.

[0003] Because stainless steel pipes are relatively long and lightweight, they have poor resistance to deformation. When subjected to external impact, the pipe body is prone to bending, which makes stainless steel pipes less practical and unable to meet the working requirements of stainless steel pipes. Therefore, a wear-resistant and bending-resistant stainless steel pipe is proposed. Utility Model Content

[0004] In order to improve the deformation resistance of stainless steel pipes, making them less prone to bending when subjected to external impacts and thus improving their practicality, this application provides a wear-resistant and bending-resistant stainless steel pipe.

[0005] This application provides a wear-resistant and bending-resistant stainless steel pipe using the following technical solution: A wear-resistant and bending-resistant stainless steel pipe includes a pipe body, and a bending-resistant layer is provided on the outside of the pipe body. The bending-resistant layer includes reinforcing parts arranged at intervals. Each reinforcing part includes a support plate arranged opposite to each other and a thickening plate that is respectively connected and fixed to both ends of the support plate. The thickening plates are connected by reinforcing plates and are cross-fixed between the thickening plates.

[0006] By adopting the above technical solution, the combination of the support plate and the thickening plate forms a frame with supporting force, and the reinforcing plate is fixed between the thickening plates in a cross pattern, forming triangular support areas on the inner and outer sides of the bending layer respectively. Thus, the bending resistance of the bending layer can be improved by combining the support plate, the thickening plate and the reinforcing plate.

[0007] Preferably, the intersecting reinforcing plates are arranged in multiple groups adjacent to each other between the thickened plates, and the ends of the multiple groups of reinforcing plates are connected sequentially.

[0008] By adopting the above technical solution, the cross reinforcing plates are set in multiple groups, and the ends of the multiple groups of reinforcing plates are connected to further enhance the structural strength between the relatively thickened plates and improve the bending resistance of the pipe.

[0009] Preferably, the bending-resistant layer further includes a connecting portion disposed between the spaced reinforcing portions, the connecting portion including an arc-shaped plate fixed between two adjacent support plates and a pressure-resistant plate fixed on the arc-shaped plate.

[0010] By adopting the above technical solution, the curved plate and the pressure plate fill the gap between two adjacent opposing support plates, thereby helping to enhance the bending resistance.

[0011] Preferably, the pressure-resistant plate is composed of horizontal connecting plates and inclined connecting plates connected sequentially at intervals; and the inclined connecting plates are connected at one end near the tube body, and the other end extends in the opposite direction at an inclination.

[0012] By adopting the above technical solution, the horizontal connecting plate and the inclined connecting plate are connected in sequence, and the included angle of the triangle formed between the inclined connecting plate and the horizontal connecting plate is used to effectively improve the compressive and bending resistance.

[0013] Preferably, the connecting part further includes a pressure-bearing plate fixed to the arc-shaped plate and located on the side opposite to the pressure-resistant plate. The pressure-bearing plate has a trapezoidal cross-section, and the lower base of the pressure-bearing plate is fixed to the arc-shaped plate, while the upper base is fixed to the side wall of the pipe body.

[0014] By adopting the above technical solutions, the pressure plate further improves the structural strength of the arc plate and the pressure-resistant plate. Through the overall cooperation of the pressure-resistant plate, arc plate, pressure plate, support plate, thickened plate and reinforcing plate, the bending resistance of the entire pipe body is improved.

[0015] Preferably, the bending-resistant layer is provided with a wear-resistant layer on the outside.

[0016] Preferably, the wear-resistant layer is a ceramic particle coating.

[0017] By adopting the above technical solution, ceramic particle coating is used to enhance the wear resistance of the pipe body.

[0018] In summary, this application includes at least one of the following beneficial technical effects: The combination of support plates and thickened plates forms a supportive frame. Reinforcing plates are cross-fixed between the thickened plates, forming triangular support areas on the inner and outer sides of the bending-resistant layer. Thus, the bending resistance of the bending-resistant layer can be improved through the combination of support plates, thickened plates and reinforcing plates. The cross-shaped reinforcing plates are set in multiple groups, and the ends of the multiple groups of reinforcing plates are connected to further enhance the structural strength between the relatively thickened plates and improve the bending resistance of the tube. The curved plate and the pressure-resistant plate fill the gap between two adjacent opposing support plates, which helps to enhance the bending resistance. The horizontal connecting plate and the inclined connecting plate are connected in sequence, and the included angle of the triangle formed between the inclined connecting plate and the horizontal connecting plate effectively improves the compressive and bending resistance. The pressure-bearing plate further improves the structural strength of the curved plate and the pressure-resistant plate. Through the overall cooperation of the pressure-resistant plate, the curved plate, the pressure-bearing plate, as well as the support plate, the thickened plate and the reinforcing plate, the bending resistance of the entire pipe body is improved.

Detailed Implementation

[0021] The present application will be further described in detail below with reference to the accompanying drawings.

[0022] This application discloses a wear-resistant and bending-resistant stainless steel pipe, referring to... Figure 1 The tube body 1 is provided with a wear-resistant layer 11 on the outside of the tube body 1. The wear-resistant layer 11 is a ceramic particle coating. An anti-bending layer 2 is provided between the tube body 1 and the wear-resistant layer 11. The wear-resistant layer 11 and the anti-bending layer 2 enhance the wear resistance and bending resistance of the tube body 1. It should be noted that during manufacturing, the pre-fabricated anti-bending layer 2 is first fixed on the outside of the tube body 1, and then the wear-resistant layer 11 is coated on the outer surface of the anti-bending layer 2.

[0023] Reference Figure 1 The bending-resistant layer 2 includes reinforcing parts 3 spaced apart. Each reinforcing part 3 includes a support plate 31 arranged opposite to each other and a thickened plate 32 respectively connected and fixed to both ends of the opposite support plate 31. The combination of the support plate 31 and the thickened plate 32 forms a frame with supporting force, thereby improving the bending resistance of the tube 1.

[0024] Reference Figure 1 The thickened plates 32 are connected by reinforcing plates 321. The reinforcing plates 321 are cross-fixed between the thickened plates 32, and multiple sets of cross-fixing reinforcing plates 321 are arranged adjacent to each other between the thickened plates 32, and the ends of the multiple sets of reinforcing plates 321 are connected in sequence. The reinforcing plates 321 are cross-fixed between the thickened plates 32, forming triangular support areas on the inner and outer sides of the bending layer 2, and the cross-fixing reinforcing plates 321 are arranged in multiple sets, and the ends of the multiple sets of reinforcing plates 321 are connected, which is used to further enhance the structural strength between the relative thickened plates 32 and improve the bending resistance of the pipe body 1.

[0025] Reference Figure 1 , 2 The bending-resistant layer 2 also includes a connecting portion 4 disposed between the spaced reinforcing portions 3. The connecting portion 4 includes an arc-shaped plate 41 fixed between two adjacent support plates 31 and a pressure-resistant plate 42 fixed on the arc-shaped plate 41. The arc-shaped plate 41 and the pressure-resistant plate 42 fill the gap between two adjacent opposing support plates 31 to help enhance the bending resistance.

[0026] Reference Figure 1 , 2The compression plate 42 is composed of horizontal connecting plates 5 and inclined connecting plates 6 connected in sequence at intervals. The horizontal connecting plates 5 extend in a direction perpendicular to the arc plate 41. The inclined connecting plates 6 are connected at one end near the inside of the tube body 1, and the other end extends in the opposite direction at an inclination. Each end of the inclined connecting plates 6 is fixed to the corresponding horizontal connecting plate 5. The horizontal connecting plates 5 and the inclined connecting plates 6 are connected in sequence, and the included angle of the triangle formed between the inclined connecting plates 6 and the horizontal connecting plates 5 is used to effectively improve the compression and bending resistance.

[0027] Reference Figure 1 , 2 The connecting part 4 also includes a pressure-bearing plate 43 fixed on the arc plate 41 and located on the opposite side of the pressure-resistant plate 42. The cross section of the pressure-bearing plate 43 is trapezoidal, and the lower bottom of the pressure-bearing plate 43 is fixed to the arc plate 41, and the upper bottom is fixed to the side wall of the pipe body 1. The pressure-bearing plate 43 further improves the structural strength of the arc plate 41 and the pressure-resistant plate 42. Through the overall cooperation of the pressure-resistant plate 42, the arc plate 41, the pressure-bearing plate 43, the support plate 31, the thickening plate 32 and the reinforcing plate 321, the bending resistance of the entire pipe body 1 is improved.
