laboratory gas circuit is mainly composed of gas source switching system, pipeline system, pressure regulation system, gas point, and monitoring and alarm system. For some flammable and explosive gases, such as hydrogen and acetylene, there may be slight differences in the design and construction process, and safety control devices must be added. So, what are the selection criteria for laboratory gas circuits?

1. Gas supply safety is the priority. According to relevant regulations, compressed gases, including compressed air, are hazardous chemicals and may cause serious personal injury in the event of an accident. Therefore, the basic function of gas supply is far from enough, and sufficient safety must be ensured.

       2. The higher the stability of the product. Many laboratories have a long testing process, and once interrupted, they need to start from scratch, which requires the gas supply system to have good stability. If the testing process is affected by cheap valves, the process will suffer a big loss.

       3,Laboratory air circuitIt is a set of equipment that has been used for a long time, and there must be maintenance problems. Therefore, maintenance convenience should also be considered in system design.

       4. Users often change the test process, resulting in the need to adjust the air supply system. Depending on the actual situation, a good system design should also be scalable.

       5. Good construction quality is also an important factor in ensuring the quality of laboratory gas lines. General layout, pipeline layout, pipeline identification, etc. It is also one of the criteria for judging the quality of a system.
