Do gas pipelines need flame arresters?
Thread Content
Gas pipelines refer to pipes that transport combustible gases such as coke oven gas, blast furnace gas, and natural gas, from the factory area to the furnaces for combustion. Are flame arresters required on the main pipelines? If anything is not clear, please let me know so I can provide further details
Add it. Without referring to the specifications, most people, when seeing such a pipe, will try to find the check valve, flame arrester, emergency shut-off valve, and so on; if they can’t locate any of them, they want to ask about it. To avoid trouble, it’s necessary to install all of them.
Take a close look at the specifications – the petrochemical fire protection codes and the furnace and pipeline design standards – and it will be clear.
Flame arresters are required for both the transportation and emission of combustible gases
Hello, questioner. A flame arrester must be installed; its purpose is to prevent fluctuations during furnace operation from causing a positive pressure in the furnace chamber, which could lead to backfire. Therefore, installing flame arresters on the fuel gas pipeline (on the side close to the furnace) can effectively prevent backflow of flames and reduce the occurrence of accidents. For the specific working principle of the flame arrester, please refer to the technical Q&A or Baidu.
