Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe technology, specifically to a high-density insulated stainless steel pipe for direct drinking water. Background Technology

[0002] Stainless steel pipe is a hollow, long, round steel material, widely used in industrial pipelines for petroleum, chemical, medical, food, light industry, and machinery, as well as mechanical structural components. Furthermore, it is lighter in weight while maintaining the same bending and torsional strength, making it widely used in manufacturing mechanical parts and engineering structures. It is also commonly used in furniture and kitchenware. The Rockwell hardness test for stainless steel pipes, like the Brinell hardness test, is an indentation test method; the difference is that it measures the depth of the indentation. The Rockwell hardness test is currently the most widely used method, with HRC being second only to Brinell hardness HB in steel pipe standards. However, current stainless steel pipes still have certain limitations in practical applications. During installation, due to the lack of effective limiting and stabilizing devices, pipes are prone to displacement and vibration, which not only affects the normal operation of the pipeline system but may also cause safety hazards. Additionally, when used for water transportation, existing stainless steel pipes often lack filtration capabilities, allowing impurities and particles in the water to easily accumulate inside the pipes, affecting water quality and reducing pipe lifespan.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] Example 1:

[0022] Please see Figures 1-4 As shown, this utility model provides a high-density insulated stainless steel pipe for direct drinking water, including a pipe body 1. A second limiting ring 4 and a first limiting ring 3 are respectively provided on both sides of the outer surface of the pipe body 1. A protrusion 2 is provided on the inner wall of the first limiting ring 3. A threaded rod 12 is fixedly installed on the top of the protrusion 2. An installation block 6 is threadedly installed on the front surface of the threaded rod 12. A filter plate 8 is provided in the inner cavity of the pipe body 1. An installation nut 9 is provided on the outer surface of the filter plate 8. An installation bolt 5 is threadedly installed on the inner surface of the installation nut 9.

[0023] This technical solution addresses the limitations of stainless steel pipes in practical applications. During installation, the lack of effective limiting and stabilizing devices makes pipes prone to displacement and vibration, which not only affects the normal operation of the pipeline system but may also cause safety hazards. Furthermore, when used for water transportation, existing stainless steel pipes often lack filtration capabilities, allowing impurities and particles in the water to accumulate inside the pipes, affecting water quality and reducing pipe lifespan.

[0024] Example 2:

[0025] Based on Embodiment 1, this utility model is as follows: Figures 1-6As shown, a sealing gasket is provided on the inner surface of the second limiting ring 4, and limiting blocks 11 are provided on both sides of the inner wall of the second limiting ring 4. An internal thread 10 is provided on the inner surface of the mounting block 6, and the internal thread 10 matches the thread of the threaded rod 12. A movable pin 7 is movably installed at one end of the second limiting ring 4 and the first limiting ring 3 that are close to each other. The filter plate 8 is made of activated carbon. The pipe body 1 includes a chlorosulfonated polyethylene coating layer 101. The outer surface of the chlorosulfonated polyethylene coating layer 101 is coated with an aluminum tripolyphosphate coating layer 102. The outer surface of the aluminum tripolyphosphate coating layer 102 is coated with a polyurea coating layer 103. The outer surface of the polyurea coating layer 103 is coated with a fluorocarbon coating layer 104.

[0026] By adopting the above technical solution, the size of the second limiting ring 4 can be adjusted by setting the movable pin 7. The internal thread 10 facilitates the user to install the mounting block 6 on the front surface of the threaded rod 12. The limiting block 11 limits the threaded rod 12. The chlorosulfonated polyethylene coating layer 101 has the advantages of good ozone resistance, chemical corrosion resistance, oil resistance, heat resistance, light resistance and wear resistance. The aluminum tripolyphosphate coating layer 102 has wide applicability, is difficult to dissolve in water, is non-toxic and has good thermal stability, and also has the effects of rust prevention, corrosion prevention and flame retardancy. The polyurea coating layer 103 has the advantages of strong adhesion, friction resistance, high hardness, good thermal stability, aging resistance and corrosion resistance. The fluorocarbon coating layer 104 has the advantages of weather resistance, heat resistance, low temperature resistance, chemical resistance, and unique non-stick and low friction.

[0027] The working principle of this utility model is as follows: the first limiting ring 3 and the second limiting ring 4 play a key role in limiting and stabilizing the pipe body 1. The threaded rod 12 fixedly installed on the protrusion 2 on the inner wall of the first limiting ring 3 cooperates with the internal thread 10 provided on the inner surface of the mounting block 6. By rotating the mounting block 6, its position on the threaded rod 12 can be adjusted, so as to achieve precise limiting and fixing of the installation position of the pipe body 1 and prevent displacement of the pipe body 1 during installation. The sealing gasket on the inner surface of the second limiting ring 4 enhances the sealing of the connection of the pipe body 1 and prevents water leakage; the limiting blocks 11 on both sides of its inner wall further assist in stabilizing the pipe body. 1. Reduced vibration solves the problem of lack of stabilizing devices during the installation of traditional pipe bodies 1, ensuring the normal operation of the pipeline system and reducing safety hazards. During water transportation, the filter plate 8 installed in the inner cavity of the pipe body 1 plays an important role in purifying water quality. The filter plate 8 is made of activated carbon, which, with its rich pore structure and strong adsorption capacity, can effectively adsorb impurities, particles, odors and some harmful chemicals in the water, filtering the water flow and preventing these substances from depositing in the pipe. This not only improves water quality but also reduces the wear of impurities on the inner wall of the pipe, extending the service life of the pipe body 1.
