A durable stainless steel U-shaped tube

Abstract

This utility model discloses a durable stainless steel U-shaped tube, specifically relating to the field of U-shaped tube technology. It includes a stainless steel U-shaped tube body, an emergency corrosion-resistant layer on the inner wall of the body, a long-term corrosion-resistant layer on the inner wall of the emergency corrosion-resistant layer, and reinforcing strips welded to the outer walls of both the front and rear sides of the body. By incorporating the emergency corrosion-resistant layer, the long-term corrosion-resistant layer, and the reinforcing strips, this utility model achieves dual corrosion resistance. Even if the long-term corrosion-resistant layer on the inner wall of the stainless steel U-shaped tube body is damaged due to an accident, the emergency corrosion-resistant layer still provides corrosion resistance. Furthermore, the reinforcing strips enhance the overall strength of the stainless steel U-shaped tube body, resulting in better pressure resistance and deformation resistance. This leads to superior durability, wide applicability, and ease of widespread use.

Description

Technical Field

[0001] This utility model relates to the field of U-shaped tube technology, and more specifically, to a durable stainless steel U-shaped tube. Background Technology

[0002] Stainless steel U-shaped pipes, as the name suggests, are pipe fittings made by bending straight stainless steel pipes into a U-shape or "hairpin" shape. They are common components in heat exchangers, condensers, evaporators, heat exchange coils, process pipelines, and sanitary equipment.

[0003] Although existing stainless steel U-tubes can be used normally, they still have many shortcomings in actual use. For example, when used to transport highly corrosive chemical media, existing stainless steel U-tubes will corrode the inner wall of the stainless steel U-tube, leading to pitting corrosion, crevice corrosion, and stress corrosion cracking. This makes existing stainless steel U-tubes less durable and have a limited range of applications. Utility Model Content

Furthermore, the dual corrosion protection design of the emergency corrosion-resistant layer 2 and the long-term corrosion-resistant layer 3 ensures that when the long-term corrosion-resistant layer 3 is damaged or cracked due to accidental collisions or other unforeseen circumstances, and cannot fully protect the inner wall of the stainless steel U-shaped tube body 1, the emergency corrosion-resistant layer 2 can provide corrosion protection. The materials of the long-term corrosion-resistant layer 3 and the emergency corrosion-resistant layer 2 can be selected according to... The selection is based on the actual application environment. The long-lasting corrosion-resistant layer 3 can achieve corrosion resistance on the inner wall of the stainless steel U-shaped tube body 1 under normal conditions. This allows the present invention to achieve dual corrosion resistance. Even if the long-lasting corrosion-resistant layer 3 on the inner wall of the stainless steel U-shaped tube body 1 is damaged due to an accident, the emergency corrosion-resistant layer 2 can still play a role in corrosion resistance. Then, the reinforcing strip 4 can improve the overall strength of the stainless steel U-shaped tube body 1, thereby making the stainless steel U-shaped tube body 1 have better pressure resistance and deformation resistance. In this way, the present invention has good durability, wide applicability, and is easy to promote and use.

Even if the long-term corrosion-resistant layer 3 on the inner wall of the stainless steel U-shaped tube body 1 is damaged due to an accident, the emergency corrosion-resistant layer 2 can still play a corrosion-resistant role. Then, the reinforcing strip 4 can improve the overall strength of the stainless steel U-shaped tube body 1, thereby making the stainless steel U-shaped tube body 1 have better pressure resistance and deformation resistance, thus making this utility model more durable, widely applicable, and easy to promote and use.
