FPB-W type gas flame arrester

The FPB-W type gas flame arrestor is designed and manufactured using the principle of extinguishing due to heat loss when the flame passes through the narrow pores of the heat conductor. Applicable to combustible gas pipelines, such as gasoline, kerosene, light diesel, benzene, toluene, crude oil and other oil storage and filling or torch systems, gas purification and Tonghua systems, gas analysis systems, coal mine gas emission systems, and heating furnace fuel gas pipeline networks , It can also be used in the pipeline supplies of acetylene, nitrogen, gas and natural gas.

1. The anti-explosion performance is qualified, and 13 consecutive anti-explosion performance tests can prevent the fire each time.

2. The burning resistance is qualified, and there is no tempering in the burning 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 check and repair, easy to install. The flame arrester core is made of stainless steel, which is corrosion-resistant and easy to clean.

Product Introduction

The FPB-W gas flame arrestor product is designed and manufactured by using the principle that the gap between the metal corrugated plates has a quenching effect on the subsonic or supersonic flame propagating in the pipeline. The product is suitable for installation in the transportation of flammable gases such as The pipe network for heating furnace fuel gas, natural gas, liquefied petroleum gas, and coal mine gas is also suitable for civil gas pipelines to prevent the reverse propagation of flames in the pipeline under abnormal conditions to avoid catastrophic accidents.

The main purpose

The FPB-W type gas flame arrestor is suitable for installation in the pipeline network that conveys combustible gas such as regenerator fuel gas, natural gas, liquefied petroleum gas, coal mine gas, and also suitable for civil gas pipelines to prevent normal conditions. The lower flame propagates backward in the pipeline to avoid catastrophic accidents. The safe fire resistance speed is 1425m/s, and the limit fire resistance speed is 1605m/s.

Structural features

The FPB-W type gas flame arrestor is originally designed and manufactured by using the slit gap between the metal corrugated plates to quench the subsonic or supersonic flame propagating in the pipeline.
