[0002] Stainless steel pipe is a hollow long round steel, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also often used as furniture and kitchen utensils. Stainless steel is more wear-resistant and indentation-resistant than other metal materials of the same thickness.

[0003] Stainless steel pipes can transport media. There are many places where stainless steel pipes are used. Some places will bury stainless steel pipes in the soil. They are mainly used to transport domestic sewage for residents. The buried location of stainless steel pipes is in the urban area. There will be a large number of cars driving on the ground, which will squeeze the stainless steel pipes for a long time. After being crushed by external forces for a long time, the compression resistance of stainless steel pipes is poor, and the surface will be cracked and worn. Not only does it need to be repaired, but it also increases the cost. The noise of the medium flowing inside the stainless steel pipe is also relatively large. The anti-oxidation and anti-deformation properties of the stainless steel pipe surface are weak. For this reason, an anti-oxidation stainless steel pipe is designed. Summary of the invention

Embodiment 2

[0023] Based on the first embodiment, Figure 1 and Figure 4As shown, an acrylic-based topcoat layer 10 is provided inside the stainless steel tube body 1, the thickness of the high-temperature resistant layer 11 is less than the thickness of the glass fiber layer 12, the surface of the acrylic-based topcoat layer 10 is in contact with the surface of the high-temperature resistant layer 11, and the surface of the glass fiber layer 12 is in contact with the other side of the high-temperature resistant layer 11. The glass fiber layer 12 has a relatively high hardness and is located inside the stainless steel tube body 1, thereby enhancing the deformation resistance of the stainless steel tube body 1. The sealing layer 13 has a sealing effect on the stainless steel tube body 1, the high-temperature resistant layer 11 and the glass fiber layer 12, so that each of them plays a greater role inside the stainless steel tube body 1.

[0024] Working principle: The stainless steel tube body 1 is a hollow long round steel. Stainless steel is more wear-resistant and indentation-resistant than other metal materials of the same thickness. The surface of the stainless steel tube body 1 is sprayed with anti-rust paint to isolate the outside world from contact with the surface of the stainless steel tube body 1, which has an anti-corrosion effect. The anti-oxidation paint used in the antioxidant layer 4 is made of ultra-fine inorganic metal oxide high-temperature solution and finely processed, and has certain heat insulation, anti-oxidation and anti-corrosion protection functions.
