Explosion resistant pipeline flame arrester is a petroleum gas pipeline flame arrester installed on pipelines that transport and discharge combustible gases, used to prevent flames from passing through at sonic or supersonic speeds. It is composed of a flame arrester element with many small channels or gaps that can pass through gas. When the flame passes through narrow pores, it is divided into many small flame streams. Due to heat transfer and wall effect, heat loss suddenly increases, Make it unable to continue burning and extinguish. This product has the characteristics of simple structure, strong flame resistance, good flame retardant effect, and high reliability. It is connected to gas conveying pipelines through flanges, which is easy to install and replace. When the pipeline network experiences tempering, the flame reduces energy through the narrow pores of the flame retardant layer core and is absorbed by thermal conductive materials, resulting in a sudden decrease in heat, effectively preventing the explosion of combustible gases.

The flame retardant core of a detonation resistant pipeline flame arrester consists of two thin layers of stainless steel strips. One is pressed into a corrugated shape, and the other flat steel strip is tightly wrapped around the center of the circle to form countless end faces, forming a small triangular straight flow channel. There is a cross shaped support (or a Y-shaped support pressed on the surface) inside to enhance the reliability of the core and avoid the pressure generated by the ignited medium from dissipating, When the medium passes through a triangular narrow channel, this product also uses it to prevent the spread of flames in the pipeline. Its principle is the wall effect, which is the energy conversion of the collision between the flame and the wall, reducing the temperature. Based on this principle, the height of the triangular hole is designed to prevent the flame from passing through. In addition, sufficient flow channel length is used to absorb the heat of the flame and extinguish it in the core, Avoiding the possibility of gas reignition at the other end of the core.

FPB gas pipeline flame arresters, also known as natural gas pipeline flame arresters, are suitable for installation in pipelines that transport combustible gases such as reheating furnace fuel gas, natural gas, liquefied petroleum gas, and coal mine gas emissions. They are also suitable for civilian gas pipelines to prevent the reverse propagation of flames in pipelines under normal circumstances, in order to avoid the occurrence of catastrophic accidents. The safe flame retardant speed is 1425m/s, and the maximum flame retardant speed is 1605m/s. This flame arrester 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.

Product flame retardant layer:

Adopting stainless steel "N" shape, double-layer corrugated tape is used as the flame retardant core, and there is a cross shaped bracket (or a Y-shaped frame pressed on the surface) inside the core to enhance its reliability and prevent the explosion pressure generated by the ignited medium from dissipating the core. Based on this principle, the height of the triangular hole is designed to prevent the passage of flames, and sufficient flow channel length is added to absorb the heat of the flame, so as to extinguish it in the core and avoid the possibility of gas re ignition at the other end of the core.
