Introduction to the performance of titanium plates and their application range

Titanium is a very active metal. Its chemical symbol is ti and its atomic number is 22. It is rich in resources and ranks third in the earth's reserves. It can be said that it is inexhaustible. It is a silver metal with a specific gravity of about 4.51 and a melting point of 1668℃. It is corrosion-resistant, has a long service life, and has a high scrap recycling price. The value of titanium scrap after scrapping is still equivalent to more than 60% of the purchase value of raw materials. It can be said that titanium material is the least wasteful material. Titanium is green and environmentally friendly and will not cause any adverse effects on the environment. The high cost of materials such as titanium plates is only the first large investment, but if it is calculated carefully after many years of use, titanium plates are an economical and practical ideal material. The ores used to produce titanium in industry include rutile, ilmenite and titanomagnetite. Due to the difficulty of separation and extraction, the metal titanium with industrial significance was not produced until the 1940s. Therefore, titanium is generally called a rare light metal.

As different products in different fields require different titanium and titanium alloy products, people process them into titanium plates, titanium rods, titanium tubes, titanium strips, titanium wires, etc., which can be provided to the majority of demanders in deep-processed shapes to meet the needs of different fields. Among them, titanium plates, titanium rods, and titanium tubes are the most widely used. titanium coil strip / Titanium Hex Nut / Grade 23 Ti-6Al-4V ELI Titanium Plate

Titanium and titanium alloys have low density and high tensile strength. In the range of -253-600 degrees Celsius, its specific strength is almost the highest among metal materials. It can form a thin and hard oxide film in a suitable oxidizing environment, which has excellent corrosion resistance. In addition, it also has the characteristics of non-magneticity and small linear expansion coefficient. This makes titanium and alloys first called important aerospace structural materials, and then promoted to shipbuilding, chemical industry and other fields, and has developed rapidly. Especially in the chemical industry, more and more products use titanium and titanium alloy products, such as petrochemicals, fibers, pulp, fertilizers, electrochemistry and seawater desalination industries, as exchangers, reaction towers, synthesizers, autoclaves, etc. Among them, titanium plates are used as titanium electrolytic plates and titanium electrolytic cells in electrolysis and sewage desalination, and are used as tower bodies and kettle bodies in titanium reaction towers and titanium reactors.

Titanium plate has good corrosion resistance

Titanium plate stands out among many metal materials for its good corrosion resistance. This material can maintain good performance in a variety of harsh environments and show strong corrosion resistance. Its corrosion resistance is mainly due to the dense oxide film formed on its surface. When it is exposed to the air, a thin and dense titanium dioxide (TiO₂) oxide film will quickly form on the surface. This oxide film can effectively prevent the contact between the corrosive medium and the titanium matrix, thereby playing a protective role.

In the marine environment, the corrosion resistance of titanium plates is particularly outstanding. Seawater contains a large amount of chloride ions, which are highly corrosive to ordinary metals, but it can be used in seawater for a long time without being corroded. For example, in shipbuilding, hull parts and seawater pipelines made of titanium plates can effectively resist the erosion of seawater, greatly extending the service life of ships. In the chemical industry, titanium plates also perform well. It can withstand corrosion from a variety of acid and alkali solutions, such as sulfuric acid, hydrochloric acid, sodium hydroxide, etc. In some chemical equipment, reactors, heat exchangers and other components made of titanium plates can operate stably in highly corrosive media, reducing the maintenance and replacement costs of equipment. Grade 23 Titanium Plate / thin titanium plate

In short, the corrosion resistance of titanium plate gives it important advantages in many fields such as ocean and chemical industry. It is a very valuable high-performance metal material.

How to ensure the quality of titanium welded pipes?

As an important pipeline material, the quality of titanium welded pipes is directly related to the safety and reliability of the project. In order to ensure the quality of titanium welded pipes, the following aspects can be controlled:

1. Choose good raw materials. The quality of titanium welded pipes is greatly affected by raw materials, so you should choose a reliable raw material supplier and strictly control the quality of raw materials. Titanium alloy is a rare metal with a high price, so it is easy to use inferior materials to impersonate. It is very necessary to strictly inspect and identify the raw materials.

2. Strictly control the production process. The process of producing titanium welded pipes generally includes extrusion, rolling, welding and other links. The process parameters of each link should be strictly controlled and inspected. Ensure that the operator has relevant operating certificates and experience, select appropriate equipment and processes, and ensure the quality of each pipe. Gr9 Ti3Al2.5V Titanium Pipe / Thin Wall Titanium Pipe / titanium exhaust tube

3. Strict quality inspection. A complete quality management system should be established in the production process, and various quality inspections should be carried out on the products regularly, including chemical composition, mechanical properties, metallographic structure, dimensional accuracy and other aspects. Only through strict inspection and control can we ensure that the products meet the standard requirements.

4. Strengthen after-sales service. After-sales service is an important part of ensuring product quality. Quality issues raised by users should be responded to and handled in a timely manner, and product traceability and feedback should be done well so as to promptly discover the causes of problems and take measures to improve them.

In general, ensuring the quality of titanium welded pipes requires all-round control and management, from the selection of raw materials to the control of production processes to quality inspection and after-sales service, and every link cannot be sloppy. Only by strict control and management throughout the process can good products that meet standard requirements be produced to provide guarantees for engineering safety and reliability.
