[0001] This application relates to the technical field of stainless steel pipes, and in particular to a bending-resistant seamless stainless steel pipe. Background Technology
[0002] In building construction, various pipe fittings are used, including the laying of pipelines and the guidance of fluids such as water. To improve the service life of pipe fittings in buildings, seamless stainless steel pipes are usually used.
[0003] Regarding the aforementioned technologies, the applicant believes that some stainless steel seamless pipes are prone to bending when subjected to certain external forces, which affects the overall use of stainless steel seamless pipes. Utility Model Content
[0004] In order to prevent stainless steel seamless pipes from easily bending when subjected to external forces and to improve their bending resistance, this application provides a bending-resistant stainless steel seamless pipe.
[0005] This application provides a bending-resistant seamless stainless steel pipe using the following technical solution:
[0006] A bend-resistant stainless steel seamless pipe includes a pipe body, a reinforcing layer fixed outside the pipe body, the reinforcing layer including bend-resistant blocks circumferentially fixed outside the pipe body and arc-shaped support plates fixed between adjacent bend-resistant blocks, a support block fixed to the end of the arc-shaped support plate corresponding to the bend-resistant block, and the bottom edge of the support block fixed to the side wall of the bend-resistant block.
[0007] By adopting the above technical solution, a reinforcing layer consisting of circumferential anti-bending blocks and arc-shaped support plates is set outside the pipe body, so that the stainless steel seamless pipe will not easily bend when subjected to external forces, thereby improving the bending resistance of the stainless steel seamless pipe and reducing the impact on the actual use of the stainless steel seamless pipe.
[0008] Preferably, the bottom of the anti-bending block is fixed with a dovetail block, and a dovetail groove is provided on the tube body for positioning the dovetail block.
[0009] By adopting the above technical solution, the dovetail block and dovetail groove make the connection between the bending block and the pipe body more stable on the one hand, and the dovetail block expands the force-bearing surface, thereby improving the resistance to longitudinal load impact and bending performance on the other hand.
[0010] Preferably, the reinforcing layer further includes pressure-resistant plates fixed at intervals to the arc-shaped support plate, with the pressure-resistant plates being staggered at intervals on the inner and outer sides of the arc-shaped support plate.
[0011] By adopting the above technical solution, the pressure-resistant plates are fixed at intervals on the arc-shaped support plate and are staggered on the inner and outer sides of the arc-shaped support plate, which better improves the structural strength and overall bending resistance of the arc-shaped support plate.
[0012] Preferably, the pressure-resistant plate includes an upper U-shaped plate and a lower U-shaped plate, with the openings of both the upper and lower U-shaped plates facing the direction of the pipe body; the upper U-shaped plate is fixed to the side of the arc-shaped support plate near the outside of the reinforcing layer, and the lower U-shaped plate is fixed to the side of the arc-shaped support plate near the pipe body, with the upper and lower U-shaped plates being staggered at intervals.
[0013] By adopting the above technical solution, the upper U-shaped plate and the lower U-shaped plate work together to improve the structural strength of the arc-shaped support plate and enhance the bending resistance of the reinforcing layer.
[0014] Preferably, the cross-section of the support block is trapezoidal, the upper base of the support block is fixed to the end of the arc-shaped support plate, and the lower base is fixed to the side wall of the anti-bending block.
[0015] By adopting the above technical solution, the trapezoidal support block has a more stable connection effect, maintaining a stable connection between the anti-bending block and the arc-shaped support plate, while expanding the force-bearing surface at both ends of the arc-shaped support plate and improving the overall structural stability.
[0016] Preferably, a carbon fiber layer is disposed inside the tube.
[0017] By adopting the above technical solution, the bending strength of the tube is improved by utilizing the carbon fiber layer.
[0018] In summary, this application includes at least one of the following beneficial technical effects:
[0019] A reinforcing layer consisting of circumferential anti-bending blocks and arc-shaped support plates is installed outside the pipe body to prevent the stainless steel seamless pipe from easily bending when subjected to external forces, thereby improving the bending resistance of the stainless steel seamless pipe and reducing the impact on the stainless steel seamless pipe in actual use.
[0020] The dovetail block and dovetail groove make the connection between the bending block and the pipe body more stable on the one hand, and the dovetail block expands the stress surface, improving the resistance to longitudinal load impact and bending performance on the other hand.
[0021] The upper U-shaped plate and the lower U-shaped plate are fixed to the arc-shaped support plate at intervals and are staggered on the inner and outer sides of the arc-shaped support plate. They work together to improve the structural strength of the arc-shaped support plate and better improve the overall bending resistance.
[0022] Trapezoidal support blocks provide a more stable connection, maintaining a stable connection between the anti-bending block and the arc-shaped support plate, while also expanding the load-bearing surface at both ends of the arc-shaped support plate, thus improving the overall structural stability.

The upper base of the support block 3 is fixed to the end of the arc-shaped support plate 22, and the lower base is fixed to the side wall of the anti-bending block 21. The trapezoidal support block 3 has a more stable connection effect, maintaining the stable connection between the anti-bending block 21 and the arc-shaped support plate 22, while expanding the stress surface at both ends of the arc-shaped support plate 22 and improving the overall structural stability.
[0029] Reference Figure 1 The reinforcing layer 2 also includes compression plates 23 fixed at intervals on the arc-shaped support plate 22. The compression plates 23 are staggered on the inner and outer sides of the arc-shaped support plate 22 to better improve the structural strength and overall bending resistance of the arc-shaped support plate 22.
[0030] Reference Figure 1The compression plate 23 includes an upper U-shaped plate 231 and a lower U-shaped plate 232, the openings of which both face the pipe body 1.
