Zirconium rod is a key material widely used in various chemical and nuclear industries. Its main function is to manufacture chemical equipment, storage containers, reactor components, etc. Specifications, physical parameters, functional advantages, chemical applications and other aspects are introduced in detail.

Basic Information

The main material of zirconium rods is metal zirconium, which plays an important role in chemical reactions and nuclear reactions due to its good chemical inertness and high strength. Zirconium rods are mainly divided into two categories, namely shaped zirconium rods and non-woven Seamed zirconium rods. Formed zirconium rods can be processed into different specifications of plates, rods, wires and other shapes according to needs; seamless zirconium rods are suitable for occasions where products need to be seamlessly processed.

Functional advantages

Good corrosion resistance: Because zirconium metal has good chemical inertness and corrosion resistance, zirconium rods can be used in various strong corrosive media, such as nitric acid, chlorine, hydrogen gas, etc.

High temperature stability: Zirconium rods have a high melting point and thermal stability, and can maintain their material structure and performance in high temperature environments without being affected.

Good processing performance: zirconium rods can be easily processed by cutting, cold processing, hot processing, welding and drilling.

·Suitable for high radioactive environment: zirconium rods have good effect in high radioactive environment such as nuclear reactors, and can effectively ensure the safe and stable operation of equipment.

Application in chemical industry

Zirconium rods are widely used in the chemical industry, and their main application scenarios include:

Petrochemical industry: Zirconium rods are widely used in oil refining, oil storage, oil pipelines and refinery equipment. Due to the complex environment of petrochemical enterprises, the medium involves highly corrosive sulfuric acid, ammonium chloride, etc., so it is necessary to The use of zirconium rods with extremely high corrosion resistance can ensure the long-term safe operation of the equipment.

Medical and biological: the field of medical and biological has extremely strict requirements on materials. As a safe, healthy and environmentally friendly equipment, zirconium rods are widely used in biological products, pharmaceuticals and other equipment. For example, in the pharmaceutical process, zirconium rods can be used To assemble the reactor and filter.

·Food processing: Zirconium rods have also been widely used in the field of food processing. Because zirconium rods have the characteristics of anti-corrosion, high temperature resistance, etc., and are non-toxic and tasteless, they can ensure the quality and health of food production.

Precautions

When using zirconium rods, it is necessary to pay attention to the flow and pressure of the medium to avoid exceeding the design specifications.

Zirconium rods will be corroded and worn by the medium during long-term operation, so regular inspection and maintenance are required.

The installation and maintenance of zirconium rods need to be operated by professionals to ensure the use effect and service life.
