Since January 1, 74 cities in China have begun to conduct comprehensive air quality monitoring. However, the air quality in most cities is not optimistic. The content of medium-fine particles such as PM2.5 is too high, and Beijing PM2.5 index The air quality continues to be "seriously polluted" in six levels, which raises higher requirements for monitoring instruments. Although European countries and the United States have developed earlier on PM2.5 monitoring equipment, they have certain technical barriers and high prices. It is understood that domestic PM instruments account for only 15% of the PM2.5 equipment installed in the monitoring points of 496 countries. Therefore, China urgently needs to develop PM2.5 monitoring instruments and technical means with independent intellectual property rights.
The project “Development and Application of PM2.5 Monitoring Equipment in Environmental Atmosphere†is one of the major projects listed in the “12th Five-Year Plan for Environmental Protection†and included in the special project of the Ministry of Science and Technology. It is also the four countries initiated by the Ministry of Environmental Protection this year. Key projects for the development of major scientific instruments and equipment. The project will research and develop PM2.5 complete monitoring equipment with independent intellectual property rights such as beta ray method, oscillatory balance method, light scattering method, sampler, etc. to enhance the core competitiveness of China's environmental monitoring instruments; cultivate engineering design, process processing, fatigue aging experiment And quality inspection and other capabilities to achieve stable and reliable quality of PM2.5 complete monitoring equipment; through application development in environmental monitoring, public health and other fields, enrich the application methods and functions of instruments and equipment; through the operation, demonstration, the establishment of China PM2.5 monitoring Domestic product quality control system and serialization method standards.
High pressure carbon steel with
zinc trivalent anti-corrosion coating per J514 standard. Flareless
compression tube fittings come fully assembled with tube Nuts and
ferrules. These fittings are used with hydraulic tubing that cannot or
does not need to be flared. Product Details Flareless Compression Tube
Fittings The male fitting has straight threads and a 24° seat. The
female connection uses a tube, tube nut, and bite-type sleeve. When the
tube nut is tightened the seal is made between the sleeve and 24° seat. A
seal is also made between the sleeve and the tubing. The threads hold
the connection mechanically.
