　　High-purity gas pipeline technology is an important part of the supply system and a key technology to deliver high-purity gas that meets the requirements to gas stores to maintain quality. It includes the correct design of the system, the selection of accessories and accessories, construction and installation, and experimental testing. In recent years, microelectronic products represented by large-scale integrated circuits have increasingly stringent requirements on the purity and impurity content of high-purity gases, and high-purity gas pipeline technology has received more and more attention and attention.

　　Many semiconductor gases are harmful to the human body. In particular, some gases, such as SiH4, are naturally flammable. Once leaked, they will react violently with oxygen in the air and start to burn. There is also the toxicity of AsH3. A slight leak can endanger a person's life. That said, due to this obvious danger, the safety requirements for system design are particularly high.

　　Application scope of high purity gas

　　Gas products are important basic raw materials for modern industry, and their application range is very wide. Metallurgy, steel, petroleum, chemical industry, machinery, electronics, glass, ceramics, building materials, construction, food processing, medicine and other departments all use a large amount of common gas or special gas. Gas application has an important impact on the cutting-edge technology in this field, and is an indispensable raw material gas or process device. Only with the needs and promotion of various emerging industrial sectors and modern science and technology can gas industry products make rapid progress in variety, quality, quantity and other aspects. Application in microelectronics and semiconductor industry

　　The use of gases plays an important role in semiconductor technology. In particular, semiconductor technology is currently widely used in various industries. From traditional ULSI, TFT-LCD to the current micro-mechanical (MEMS) industry, the so-called semiconductor process is used as the manufacturing process of products. The processes include dry etching, oxidation, ion trapping, ion trapping,

　　The Importance of High-Purity Pipelines in High-Purity Gas Transportation

　　During the stainless steel smelting process, each ton of material can absorb about 200 grams of gas. After processing, not only are various pollutants attached to the surface, but a certain amount of gas is also absorbed in the metal lattice. When the airflow passes through the pipeline, this part of the gas absorbed by the metal enters the airflow again. When the airflow in the pipe is discontinuous, the pipeline applies pressure adsorption to the passing gas. When it stops passing, the gas adsorbed in the pipe forms a coercive analysis, and the interpreted gas also enters the pure gas in the pipe as an impurity. At the same time, with the repetition of the adsorption and analysis cycle, the metal on the surface of the pipe will also produce a certain amount of powder, and these metal dust particles will also contaminate the pure gas in the pipe. This characteristic of the pipeline requires not only a very high softness of the internal surface of the pipeline, but also a higher wear resistance to ensure the purity of the high-purity gas being transported.
