Description of titanium alloy plates and the application range of titanium materials in various industries.
Due to its corrosion resistance, mechanical properties, and processing performance, titanium is widely used in many sectors of the national economy. Especially in chemical production, titanium is used to replace stainless steel, nickel-based alloys, and other rare metals as corrosion-resistant materials, which is of great significance for increasing output, improving product quality, extending equipment lifespan, reducing consumption, lowering energy use, cutting costs, avoiding pollution, improving labor conditions, and enhancing productivity. In recent years, the scope of titanium used in the chemical industry in our country has been continuously expanding, with annual increases in usage, and titanium has become one of the primary corrosion-resistant materials in chemical equipment. As a corrosion-resistant structural material used in chemical installations, titanium has established its position, and as an ideal material in chemical equipment, it is increasingly attracting the attention of engineering technicians.
(1) Chlor-alkali Industry
The chlor-alkali industry is an important basic raw material industry, and its production and development have a significant impact on the national economy. This is because titanium's corrosion resistance to chloride ions is superior to that of commonly used stainless steel and other non-ferrous metals. Currently, titanium is widely used in the chlor-alkali industry to manufacture metal anode electrolytic cells, ion-exchange membrane electrolytic cells, wet chlorine coolers, refined brine preheaters, dechlorination towers, chlorine gas cooling scrubbers, and more. The main components of these devices were previously made from non-metallic materials (such as graphite, polyvinyl chloride, etc.), but the mechanical properties, thermal stability, and processing performance of non-metallic materials are not ideal, resulting in bulky equipment, high energy consumption, short lifespan, and affecting product quality and environmental pollution.
(2) Soda Ash Industry
Soda ash is one of the basic chemical raw materials, directly related to the development of the national economy. In the production process of soda ash, the gaseous media are mostly NH3 and CO2, while the liquid media are mostly NaCl, NH4Cl, NH4HCO3, and solutions with high Cl- concentration. The main equipment for carbonation reactions using carbonated drinks and cast iron materials, such as carbonation tower small tubes, hot mother liquor coolers, coolers, and crystallization external coolers, are all not corrosion-resistant, leading to severe corrosion leaks, with a lifespan not exceeding three years.
Titanium and its alloys have many excellent properties such as light weight, high strength, strong heat resistance, and corrosion resistance, earning them the title of 'metal of the future.' They are emerging structural materials with development prospects. Titanium and its alloys not only have very important applications in the aerospace and spaceflight industries but have also begun to be widely used in many industrial sectors such as chemical, petroleum, light industry, metallurgy, and power generation.

What are the five main characteristics of titanium plates?
Features: 1. The titanium seed plate has a surface oxide film that acts as a good, durable release agent, saving the use of release agents and making the peeling of the plates easier, eliminating the need for pre-treatment of the seed plates. The titanium seed plate is half the weight of the copper seed plate. 2. The lifespan of the titanium seed plate is more than three times that of the copper seed plate, and can reach 10 to 20 years depending on operating conditions. 3. The electrolytic copper produced using titanium seed plates has a dense crystalline structure, a smooth and flat surface, and high quality. 4. Since titanium seed plates do not require the application of release agents, they can avoid contamination of the copper electrolyte. 5. Increased production capacity reduces the production costs of electrolytic copper, resulting in better economic benefits.
What are the technical requirements for titanium pipes?
Titanium pipes are lightweight, have high strength, and excellent mechanical properties. They are widely used in heat exchange equipment, such as shell-and-tube heat exchangers, coil heat exchangers, serpentine tube heat exchangers, condensers, evaporators, and transport pipelines. Many nuclear power industries use titanium pipes as standard pipes for their units.
Technical requirements:
1. The chemical composition of titanium and titanium alloy pipes should comply with the provisions of GB/T3620.1. When the buyer conducts re-inspection, the allowable deviation of the chemical composition from Mingkun Titanium Industry should comply with the provisions of GB/T3620.2.
2. The allowable deviation of the outer diameter of the pipe should comply with the specifications in Table 1.
3. The allowable deviation of the wall thickness of the pipe should not exceed its nominal wall.
What should be noted when filtering materials with titanium pipes?
Precautions: 1. If using titanium plate as a filtering material, it must not exceed its maximum working capacity. 2. When using titanium plates as filtering materials, be sure to prevent the plates from being bumped or scratched, and keep them clean to avoid contamination. 3. After using the titanium plate material, it must be cleaned and stored properly. 4. Before starting work, the titanium plate filtering material must be activated before adjusting to the normal working environment.
