Pipe flame arrester 
 Valve Type: GYW-1 
 GYW-1 pipe flame arresters, also known as GYW-1 resistance-type pipe deflagration flame arrester, flammable gas pipe line of new flame arresters, is a new replacement product. 
 GYW-1 pipe flame arresters by the China University of Science and Technology, Tianjin Fire Research Institute and the Ministry of Public Security jointly test the performance of full compliance with GB13347-92 "oil and gas pipeline fire retardant flame arrester performance and test methods" requirement. Flame arrester reasonable structure, fire retardant layer made of stainless steel, corrosion-resistant easy to clean. Housing of stainless steel, carbon steel and other materials to meet the needs of various process piping. 
 Pipe flame arrester performance and features: 
 The flame arrester reasonable structure, light weight, corrosion resistance, resistance explosive performance qualified for 13 consecutive times to subsonic flame test every time fire retardant. Easy maintenance, easy installation. Qualified fire-resistant properties, fire resistance test one hour of non tempering phenomenon. Flame arrester cores of stainless steel, corrosion-resistant, easy to clean. Shell pressure test pass. 
 Pipe flame arrester application: 
 The flame arrestor for pipelines, flash point 28 ℃ lower than the CPI, oil, liquefied hydrogen and oxygen, and a flash point below 60 ℃ like kerosene, diesel oil, toluene and crude oil, pipeline transportation of flammable gas, torch series, oil and gas recovery system, heating fuel gas pipe-line, Tonghua gas purification systems, gas analysis systems, coal mine gas drainage system 
 Pipe flame arrester main purposes: 
 1, flammable gas transmission pipeline. 
 2, the flare system. 
 3, oil and gas recovery system. 
 4, heating fuel gas pipe-line. 
 5, Tonghua gas purification system. 
 6, gas analysis system. 
 7, coal mine gas drainage system. Key Features 1, flame arrester 13 consecutive times to subsonic flame test, every time to prevent passage of flame. 
 Flame arrester pipe maintenance and repair: 
 In order to ensure that the flame arrester performance to achieve the purpose of the safe use of flame arresters should be checked regularly, and maintenance. 
 1, inspected once every six months flame arrester, check whether the blocked fire retardant layer cores, deformation, corrosion, etc. 
 2, found to be blocking the fire retardant layer wick should be cleaned to ensure smooth flow of wick on each hole, the deformation and corrosion of the fire retardant layer should be replaced. 
 3, re-install the fire retardant layer cores, should ensure that no leak tight joint surface.
