High-purity gas, a term in the gas industry, usually refers to gas with a certain purity level that can be achieved by modern purification technology. High-purity gas can be divided into organic high-purity gas and inorganic high-purity gas according to different molecular structures. Now high-purity gas pipeline projects are common projects in our daily life and industrial production, among which gas pipeline installation is related to the performance and quality of the entire project.

　　High-purity gas pipeline engineering is a gas pipeline engineering specially designed for transporting various high-purity gases such as high-purity helium, high-purity oxygen, high-purity nitrogen, high-purity hydrogen, high-purity argon, etc. It is commonly used in inspection and quarantine, biopharmaceuticals, colleges and universities, chemical food companies, water quality and oil analysis and other analytical laboratories.

　　What are the performance characteristics of high-purity gas pipelines after installation? The following is a detailed introduction:

　　1. The permeability of the pipeline should be small;

　　2. The adsorption and desorption of gases have little effect on the inner surface of the pipeline;

　　3. The inner wall is smooth and wear-resistant;

　　4.Good corrosion resistance;

　　5. Stable performance and low carbon content.

　　The above excellent performance is mostly based on the selection of materials and valves, compliance with the national technical requirements for pipeline installation and construction precautions (such as the main pipe of the gas pipeline project should be laid in the upper and lower technical mezzanines or technical clamps, and should be installed on the upper part when shared with water and electricity pipelines), and inspection and maintenance of the gas pipeline.

　　At present, in laboratories or factories, in high-purity gas pipeline projects, all high-purity and high-cleanliness gases need to be transported to various instrument points through pipelines. Therefore, in order to ensure the performance of high-purity gas pipelines and meet the quality requirements of instrument gas, more attention should be paid to the material selection, pipeline laying, construction quality and other gas pipeline installation work of the pipeline system.
