FPB Natural gas flame arrester Natural gas flame arrester Brief description
FPB natural gas flame arrester Suitable for installation in the transport of combustible gases such as reheating furnace fuel gas, natural gas, liquefied petroleum gas, coal mine gas emissions pipeline, also applies to civilian gas pipe to prevent Under normal circumstances the flame propagation in the reverse pipeline to avoid catastrophic accidents. FPB natural gas flame arrester fire safety speed of 1425m / s, the ultimate fire resistance speed 1605m / s. FPB natural gas flame arrester is the use of metal corrugated board gap between the propagation of the sub-sonic or supersonic flame quenching effect of the original design and manufacturing.
