FPB natural gas flame arrester (carbon steel | stainless steel)

FPB Natural Gas Flame Arrester (Carbon Steel | Stainless Steel) Product Overview

Gas flame arresters are suitable for installation in pipelines that transport flammable gases such as heating 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 the pipeline under abnormal conditions, in order to avoid catastrophic accidents. Pipeline natural gas flame arresters are widely used in natural gas transmission pipelines in industries such as metallurgy and chemical engineering, such as heating furnace fuel gas, liquefied petroleum gas, coal mine gas emissions, and also applicable to civilian gas pipelines. It can effectively cut off the ignition source caused by the rapid friction between debris and the pipe wall in high-speed airflow, and prevent the reverse propagation of flames in the pipeline under abnormal conditions. Eliminate the occurrence of pipeline explosion accidents.

This product has a safe flame retardant speed of 1425m/s; Limit flame retardant speed 1605m/s; Customers can directly weld and connect this product to the appropriate part of the natural gas pipeline for operation.

Working principle of FPB natural gas flame arrester (carbon steel | stainless steel)

Gas flame arresters are designed and manufactured based on the principle of quenching subsonic or supersonic flames propagating in pipelines using narrow gaps between metal corrugated plates. The connecting flange of this product is designed and manufactured according to HG20595-97 concave convex surface neck welded steel pipe flange. Users need to choose other standard connecting flanges. Please specify in the order for gas flame arresters with PN>4.0MPa.
