The FPB-W type gas flame arrester is designed and manufactured based on the principle of extinguishing flames due to heat loss when they pass through narrow pores in thermal conductors. Suitable for storage and flare systems of combustible gas pipelines, such as gasoline, kerosene, light diesel, benzene, toluene, crude oil and other oil products, gas purification systems, gas analysis systems, coal mine gas emission systems, heating furnace fuel gas pipeline networks, and can also be used as pipeline supplies for acetylene, nitrogen, gas, and natural gas.

1. The explosion resistance performance is qualified, and it can withstand fire for 13 consecutive explosion resistance tests.

2. The fire resistance performance is qualified, and there is no tempering phenomenon in the fire resistance test for 1 hour.

3. The shell water pressure test is qualified. This product has a reasonable structure, light weight, and corrosion resistance. Easy to maintain and install. The core of the flame arrester is made of stainless steel material, which is corrosion-resistant and easy to clean.

Product Introduction

The FPB-W type gas flame arrester product is designed and manufactured based on the principle that the narrow gap between metal corrugated plates has a quenching effect on subsonic or supersonic flames propagating in pipelines. The product is suitable for installation in pipelines that transport combustible gases such as heating furnace fuel gas, natural gas, petroleum liquefied gas, and coal mine gas emissions. It is also suitable for civilian gas pipelines to prevent the reverse propagation of flames in pipelines under abnormal conditions, To avoid catastrophic accidents.

Main uses

The FPB-W type gas flame arrester is suitable for installation in pipelines that transport combustible gases such as fuel gas from reheating furnaces, natural gas, liquefied petroleum gas, and coal mine gas emissions. It is also suitable for civilian gas pipelines to prevent the reverse propagation of flames in pipelines under normal conditions and avoid the occurrence of catastrophic accidents. The safe flame retardant speed is 1425m/s, and the maximum flame retardant speed is 1605m/s.

Structural characteristics

The FPB-W type gas flame arrester was originally designed and manufactured to use the narrow gap between metal corrugated plates to quench subsonic or supersonic flames propagating in pipelines.
