Description du produit
Zirconium tube is a tubular product made of zirconium material, which has the characteristics of high temperature resistance and corrosion resistance. In the nuclear industry, chemical industry, metallurgy and other fields, zirconium tubes are widely used, especially when they need to withstand extreme conditions, such as high temperature, high pressure or highly corrosive environments.

The following are some characteristics of zirconium tubes:

1. High melting point: The melting point of zirconium is very high, about 1852°C, which allows zirconium tubes to be used in operations at high temperatures.
2. Corrosion resistance: Zirconium has good resistance to many chemicals, including acids, alkalis, and salts, so it can be used to handle a variety of corrosive substances.
3. Anti-oxidation: At high temperatures, many metal materials will oxidize rapidly, but zirconium can form a protective oxide film at high temperatures, thus having good oxidation resistance.
4. Low pollution: Due to the good chemical stability of zirconium, it does not easily react with other substances, so it can reduce the introduction of impurities and improve product purity.
5. Good thermal conductivity: Zirconium has a high thermal conductivity, allowing the zirconium tube to effectively transfer heat during the heat exchange process.

6. Good mechanical properties: Zirconium has good strength and hardness, which makes the zirconium tube have good stability when subjected to high pressure or mechanical stress.
