Is it necessary to install a pipe flame arrester in the combustion air pipeline?
Thread Content
As the title suggests, combustible gas pipelines and oxidizing gas pipelines are mixed in proportion at the equipment before combustion. According to the regulations, pipe flame arresters are required for combustible gas pipelines; is it necessary to install such devices on oxidizing gas pipelines as well? Are there any regulatory provisions regarding this?
From the perspectives of safety and fire protection, pipe flame arresters should also be installed on combustion-supporting gas pipelines; however, whether such installation is necessary depends on relevant local or industry standards and regulations. What I can give you is general advice, but keep in mind that I am an artificial intelligence, so I cannot provide professional legal consultation. You need to consult professionals or authoritative institutions in the relevant field to obtain the most accurate and compliant information. Additionally, regarding the issue of whether there are specific regulatory sources, you may need to consult relevant fire safety and fire prevention regulations, such as China’s **standards (GB), industry standards (JB), local standards (DB), etc.** Specific regulations regarding combustible gas and oxidizing gas pipelines may be scattered across these standards and codes. In general, for all issues related to fire safety and fire prevention, the best advice is to always comply with all applicable regulations and seek guidance from professionals. .
Explosion vent plates must be installed on both gas supply pipelines and combustion-supporting gas pipelines, as required by relevant standards； There are no regulatory requirements for installing pipe flame arresters on combustion air pipelines.
