Flame arrester structure
Thread Content
For general manufacturers of flammable and explosive hazardous chemicals, vehicles that are not special-type vehicles are required to be equipped with flame arrestors when entering the factory; our company is no exception. However, I have doubts about the design of the flame arrestors produced by our company – it seems to me that they cannot prevent the spread of flames. Since I don’t know much about the structure of flame arrestors, I’m wondering if there are any requirements, standards, or specifications regarding their manufacture
Firstly, what the original poster refers to as a \"flame arrester for vehicles\" should actually be called a \"spark extinguisher for vehicle exhausts.\" There are standards for this device: \"GB 13365-2005 | Spark Extinguishers for Vehicle Exhausts\" http://bbs.hcbbs.com/thread-80113-1-1.html
Please try typing “flame arrester” in the search bar. . For these, reference can be made to HG-T 20570.19-95 regarding the installation of flame arrestors, SH-T 3413-1999 on the selection, inspection, and acceptance of flame arrestors for petrochemical and oil pipelines, and GB13347-92 on the flame-arresting performance and testing methods of flame arrestors used in oil and gas pipelines
Are these for the pipes, or can we take a look at those on the 2nd floor?
A vehicle flame arrester is essentially a short tube into which some wire mesh is inserted to prevent sparks from escaping directly from the exhaust pipe.
The flame arrestors used in explosion-proof areas certainly cannot be chosen as casually as mentioned above!
The principle of flame arresters is the same: the flame passes through a narrow space formed by a metal mesh, and dies out as heat is lost.
