Product details

FPA gas flame arrester Overview
        FPA gas flame arrester, also known as FPA natural gas flame arrester, using two GZW-1 flame arrester combination is widely used in metallurgy, chemical and other industries natural gas pipeline, such as heating furnace fuel gas, liquefied petroleum gas , Coal gas emissions, but also for civilian gas pipelines. Which can effectively cut off the fire source caused by the rapid friction between the debris and the pipe wall in the high-speed airflow and prevent the reverse propagation of the flame in the pipeline under abnormal conditions. Eliminate the occurrence of pipeline explosion explosion. FPA gas flame arrester safety fire resistance speed 1425m / s; ultimate fire resistance speed 1605m / s. Customers can directly connect the product with the appropriate parts of the natural gas pipeline can be connected to run. 
 
 FPA gas flame arrester works 
       FPA gas flame arrester is the use of metal corrugated disk gap between the sub-sonic or supersonic flame propagating in the pipeline has the principle of quenching the design and manufacture of this product's connecting flange According to HG20595-97 concave and convex surface with neck welded steel pipe flange design and manufacture, users need to use other standard connection flange, please specify in the order, for PN> 4.0MPa gas flame arrester. 
 
 
 FPA-type gas flame arrester structure special
 
 1, FPA gas flame arresters on the pipeline subsonic or supersonic flame quenching role; 
 2, the product generally with matching flange, the standard HGJ standard; 
 3, the product can And piping system, can also be adjusted with the valve, breathing valve connection;


 The main performance of FPA gas flame arrester
 
 1, explosive performance standards for 13 consecutive burst resistance test fire resistance can be. 
 2, resistance to burning qualified, burning test 1 hour no tempering phenomenon. 
 3, shell water pressure test qualified. The product structure is reasonable, light weight, corrosion-resistant. Easy maintenance, easy installation. Flame arrester core stainless steel, corrosion-resistant easy to clean.
