Fill-in-the-blank: （ ） is commonly used in low-pressure flammable gas pipelines, where the end of the pipeline is at a location with an open flame or where there is a possibility of an open flame being generated. Answer: Flame arrester
To be filled in: Flame arrester. Flame arresters are commonly used on low-pressure flammable gas pipelines, where the end of the pipeline is exposed to open flames or in areas where open flames may occur. When the pressure of the medium in the pipeline decreases, backflow of the medium may draw an open flame back to the source of the medium, resulting in a fire or explosion. At the end of these pipes, installing a flame arrester can prevent or stop flames from spreading back along with the flow of the medium into the pipes or equipment where the medium originates. Since a flame arrester is a safety component, its manufacturers must be approved by the fire department.
(Fire arrestors) are commonly used on low-pressure combustible gas pipelines, where the end of the pipeline is at a location with an open flame or facilities that may generate an open flame.
Is it a flame arrester? ? ? ? ?
Is it an ever-burning lamp? Haha, I’ll give it a try!
