I floatation of Hichine’s  production pipeline fire retardant type is a device installed at the ends of the tube or pipe near the end of the pipeline, Flame to prevent vertical transmission and spread of fire retardant devices, widely used furnace fuel gas, natural gas, liquefied petroleum gas pipe in the road, and oil and gas recovery, gas purification, gas, coal gas emissions, can effectively guarantee that gas pipelines and gas use of the security operation.

Screen fire retardant devices should be installed in the fuel gas or flammable liquid vapor entering the nozzle before the pipeline. When the nozzle temper, the two semi-metallic silk wall due to the effect of thermal conversion can flame out, Combustible gases and prevent flammable liquid vapor and prevent the spread of flame temper and cause an explosion.
