Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pipe equipment, in particular to a high-strength stainless steel pipe. Background Art

[0002] Stainless steel pipe is a kind of metal pipe with corrosion resistance, made of stainless steel material. Stainless steel pipe is mainly composed of iron, chromium, nickel and other elements. It is widely used in the manufacture of mechanical parts and engineering structures, and is also commonly used as furniture and kitchen utensils.

[0003] A Chinese patent with patent publication number CN211010208U discloses a high-strength stainless steel pipe, which relates to the field of steel pipes, including an outer stainless steel pipe, a reinforcement layer is arranged inside the outer stainless steel pipe, an arc-shaped connecting plate is fixedly connected between the outer stainless steel pipe and the reinforcement layer, a plurality of support members are arranged on the outside of the reinforcement layer, a filling layer is arranged between the outer stainless steel pipe and the reinforcement layer, an inner stainless steel pipe is fixedly connected to the inner surface of the reinforcement layer, a reinforcement ring is fixedly connected to the inner surface of the inner stainless steel pipe, a plurality of reinforcement rings are arranged, connecting rods are fixedly connected between the plurality of reinforcement rings, and a coil spring is fixedly connected to the outer side surface of the inner stainless steel pipe.

[0004] Although the existing high-strength stainless steel pipes have solved the problem of low strength of stainless steel pipes, due to their complex structure, they have a large deadweight. Heavier stainless steel pipes require more logistics resources during transportation, including larger transport vehicles, more fuel and higher transportation costs. Especially in long-distance transportation or large-volume transportation, the increase in weight may significantly increase the overall transportation cost; in addition, in some application environments, stainless steel pipes may be used for supporting and load-bearing structures. The larger weight may increase the requirements for the supporting structure and may require more powerful support and reinforcement measures, increasing the difficulty and cost of engineering design and construction. Therefore, it is necessary to develop a stainless steel pipe with high strength and light deadweight. Utility Model Content

[0005] The utility model aims to provide a high-strength stainless steel pipe, which solves the problem of heavy weight of traditional high-strength stainless steel pipes.

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings of the present utility model specification.

[0020] Example:

[0021] like Figure 1 , 2As shown, a high-strength stainless steel pipe described in this embodiment includes a first steel pipe layer 1, a vacuum layer 2, a carbon fiber layer 3, and a second steel pipe layer 4 arranged in sequence from the inside to the outside. The thickness of the first steel pipe layer 1 is 3 mm, and the thickness of the vacuum layer 2 is 9 mm. By setting the vacuum layer 2, the density of the vacuum layer 2 is smaller than that of the air, so an upward buoyancy is generated, thereby greatly reducing the dead weight of the stainless steel pipe, reducing the transportation cost, and reducing the structural load. The thickness of the second steel pipe layer 4 is 3 mm. The end of the first steel pipe layer 1 is sealed between the end of the second steel pipe layer 4 to form the vacuum layer 2. The carbon fiber layer 3 is fixed to the second steel pipe layer 4 by an adhesive. The inner wall of the steel tube layer 4, since the second steel tube layer 4 is usually first subjected to the impact force, a carbon fiber layer 3 is arranged on the inner wall of the second steel tube layer 4, which can effectively avoid the deformation of the stainless steel tube; the strength of the device is effectively improved by arranging the carbon fiber layer 3 and the second steel tube layer 4 to cooperate with each other, and the carbon fiber is light in weight, which can ensure that the strength of the device is significantly improved with a lighter weight; the outside of the second steel tube layer 4 is coated with a wear-resistant layer 5, and the wear-resistant layer 5 is a ceramic coating, and the ceramic coating has excellent hardness and wear resistance. By arranging the wear-resistant layer 5, the wear resistance of the device is greatly improved, the protection of the device is strengthened, and the service life of the device is extended.
