Description

Technical Field

[0001] The utility model belongs to the technical field of pressure vessel supports, and in particular relates to a titanium and zirconium container supporting type steel pipe support. Background Art

[0002] In the chemical, petroleum, nuclear energy and other industries, pressure vessels are key equipment for storing and transporting media, and their safety and stability are of vital importance. Since the working environment of these industries is often characterized by high temperature, high pressure, and strong corrosion, extremely high requirements are placed on the material selection, structural design, and manufacturing process of pressure vessels. Titanium and zirconium, as special metal materials, have been widely used in the manufacture of pressure vessels due to their excellent corrosion resistance and good high-temperature performance.

[0003] However, the welding characteristics of titanium and zirconium materials have brought certain challenges to their application. Titanium, zirconium and conventional materials such as carbon steel have significant differences in physical and chemical properties, which makes welding between them extremely difficult and cannot ensure sufficient welding strength. Especially in an environment with a design temperature of 70 to 300 degrees Celsius, the allowable stress of titanium and zirconium materials will drop sharply, making it difficult for pressure vessel support brackets made of titanium and zirconium materials alone to meet the required support strength. In addition, since thick-walled pipes are difficult to purchase, the overall rigidity of the support pipe is reduced.

[0004] Therefore, how to give full play to the advantages of titanium and zirconium materials under the premise of ensuring welding reliability, improve the supporting strength of pressure vessel support bearings, and control material costs at the same time has become a problem that needs to be solved urgently.

[0026] A pad 6 is installed on the top of the top support tube 5. Through the setting of the pad 6, the pad 6 is used to support the titanium or zirconium pressure vessel on the top. A bottom plate 1 is installed on the bottom of the bottom support tube 2. Through the setting of the bottom plate 1, the bottom plate 1 can connect the bottom support tube 2 to the external supporting equipment or the ground.

The use of pure titanium and zirconium is mainly to ensure the welding reliability of the connection between the support structure and the pressure vessel head. The use of carbon steel ensures the overall strength of the support and greatly saves material costs.

[0029] When installing the bottom connecting plate 3 and the top connecting plate 7, the bottom connecting plate 3 and the top connecting plate 7 are fitted together, and the threaded column 9 is screwed into the threaded hole 10 corresponding to the bottom connecting plate 3 and the top connecting plate 7, and the nut 8 is screwed into the lower part of the bottom connecting plate 3 and the upper part of the top connecting plate 7 to fix the bottom connecting plate 3 and the top connecting plate 7, so as to ensure that the bottom supporting tube 2 and the top supporting tube 5 are installed more firmly, and the pure titanium and zirconium parts of the support are connected with the carbon steel part through the nut 8 and the threaded column 9. This design adopts a non-welding mechanical connection method to ensure the connection strength and stability between different materials. This connection method is an important improvement on the traditional welding method, especially considering the difficulty of welding titanium, zirconium and carbon steel;

[0030] A plurality of reinforcement members are respectively provided on the top connecting plate 7 and the bottom connecting plate 3 .

[0032] The overall rigidity of the bottom support tube 2 and the top support tube 5 is enhanced and the challenge of the difficulty in sourcing thick-walled tubes is solved. This reinforcement measure improves the stability of the structure without relying on thicker tubes.
