On March 5, 2022, the government work report of the fifth session of the 13th National People's Congress mentioned: "Around the major national strategic deployment and the 14th Five-Year Plan, moderately advanced infrastructure investment. Construct key water conservancy projects, comprehensive three-dimensional transportation networks, important energy bases and facilities, accelerate the renovation of urban gas pipelines and other pipe networks, improve flood prevention and drainage facilities, continue to promote the construction of underground comprehensive pipe corridors, and invest 640 billion yuan in the central budget. ”
Gas safety is closely related to people's production and life, and has become the top priority of urban emergency management.
Sifang Optoelectronics masters a variety of core technology platforms and applications such as non-spectroscopic infrared (NDIR), tunable semiconductor laser absorption spectroscopy (TDLAS), electrochemistry, etc., can measure flurrible gases such as CH4, C3H8, CO and toxic and harmful gases, and provides a full set of gas leakage safety monitoring solutions, which are widely used in household, commercial, industrial and other fields to empower the safety monitoring of urban gas pipeline networks.
