Flame arrester

GZW-1 type resistance deflagration type pipe flame arrester is a new model of combustible gas pipeline fire, new products update.
The flame arrester was tested by the Tianjin Institute of fire science, University of Science & Technology China and the Ministry of public security, and its performance was fully in line with the provisions of GB13347-92 "fire resistance performance and test method of fire resistance of petroleum gas pipeline". The flame arrester is of reasonable structure, and the fire resistant layer is made of stainless steel, and the corrosion resistance is easy to clean. The shell is made of stainless steel, carbon steel and other materials, which can meet the needs of various process pipelines.
The flame arrester for pipeline, flash point below 28 DEG C A, oil, liquefied oxygen and flash point below 60 DEG C, kerosene and diesel oil, toluene, transportation of flammable gas pipeline, torch series, oil and gas recovery system, heating furnace fuel gas pipeline network, gas purification, gas system in Tonghua coal mine gas drainage system, analysis system.
