    Detonation resistance pipeline flame arresteris a kind of petroleum gas pipeline flame arrester installed on the pipeline for conveying and discharging combustible gas to prevent the flame from passing through at sonic or supersonic speed. It consists of a kind of gas that can pass through and has many small When the flame passes through the narrow pores, it is divided into many small flame streams. Due to the heat transfer and the wall effect, the heat loss suddenly increases, making it unable to continue to burn and extinguish. This product has the characteristics of simple structure, strong burning resistance, good fire resistance effect and high reliability. It is connected with the gas transmission pipeline by flanges, which is convenient to install and easy to replace. When the pipe network is backfired, the flame will pass through the fire resistance. After the narrow pores of the layer core reduce energy and are absorbed by the thermal conductive material, the heat is suddenly reduced, thereby effectively preventing the detonation phenomenon of combustible gas.

    The flame arrestor core of detonation type pipeline flame arrester consists of two thin stainless steel strips, one is pressed into a corrugated shape, and the other flat steel strip is tightly wound around the center of the circle, forming countless end faces, forming a small triangle Straight through the flow channel, and there is a cross-structured bracket (or a Y-shaped bracket on the surface) to enhance the reliability of the core and avoid the pressure generated by the ignited medium. When the medium passes through the triangular narrow channel, This product also uses it to prevent the flame from spreading in the pipeline. The principle is the wall effect, that is, the collision between the flame and the wall for energy conversion and lower the temperature. Based on this principle, the height of the triangular hole is designed to prevent the flame. By adding enough flow path length to absorb the heat of the flame and extinguish it in the core, the possibility of re-ignition of the gas at the other end of the core is avoided.

    FPB gas pipeline flame arrestor, also known as natural gas pipeline flame arrestor, is suitable for installation in the pipeline network that transports combustible gases such as regenerator fuel gas, natural gas, liquefied petroleum gas, and coal mine gas. It is also suitable for civil gas pipelines to prevent normal In this case, the 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. The flame arrestor is designed and manufactured 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.

    Product fire barrier:

    The stainless steel "N" shape is adopted, the double-layer corrugated belt is used as the fire-resisting core, and there is a cross structure bracket (or a Y-shaped frame on the surface) inside the core to enhance the reliability of the core and prevent the core from being ignited The explosive pressure generated by the medium is dissipated. Based on this principle, the height of the triangular hole is designed to prevent the flame from passing through, plus enough flow channel length to absorb the heat of the flame and extinguish it in the core, avoiding the possibility of re-ignition of the gas at the other end of the core. sex.

    ​Product features:

    1. It is an explanation of the design and manufacture of the principle that the gap between the metal corrugated plates has a quenching effect on the subsonic or supersonic flame propagating in the pipeline.

    2. It is suitable for installation in the pipeline network for conveying combustible gas, such as heating furnace fuel gas, liquefied petroleum gas, coal mine gas, and also suitable for civil gas pipelines.

    3. Prevent the reverse propagation of flame in the pipeline under abnormal conditions, so as to avoid the occurrence of air accidents. This product has a safe fire resistance speed of 1425m/s and a limit fire resistance speed of 1605m/s.
