GZW-1 Pipeline Fire GZW-1 Pipeline Fire performance and features:? Pipeline Fire reasonable structure, light weight, corrosion resistance, explosion resistance performance standards, 13 consecutive times to the test every time subsonic flame arrester. ? Pipeline Fire easy maintenance, easy installation. Resistance to fire performance standards, resistance to fire test one hour without tempering phenomenon. ? Pipeline Fire cores made of stainless steel, corrosion-resistant, easy to clean. Casing pressure test pass. GZW-1 Pipeline Fire Scope: Pipeline Fire applies to pipes, a flash point below 28 ℃ in the CPI, oil, hydrogen liquefaction classes and a flash point below 60 ℃ of kerosene, diesel, crude oil, etc. A stupid, the combustible gas pipeline, torch series, oil and gas recovery system, furnace fuel gas pipe line, gas purification Tonghua system, gas analysis systems, coal mine gas drainage system. GZW-Ⅰ type deflagration type Pipeline Fire Department new combustible gas Pipeline Fire, is a new product replacement. The flame arrester by the Chinese Ministry of Public Security, Tianjin Institute of Science and Technology, University of Science and fire combined test, the performance in full compliance GB13347-92 "oil and gas pipelines flame arrester and test methods" requirement. Zuhuo reasonable structure, fire resistant layer made of stainless steel, corrosion-resistant and easy to clean. Housing made of stainless steel, carbon steel and cast a variety of materials to meet the various needs of different process piping. Pipeline Fire main purposes: 1, the pipeline transportation of flammable gases. 2, the flare system. 3, oil and gas recovery system. 4, furnace fuel gas pipe-line. 5, Tonghua gas purification system. 6, the gas analysis system. 7, coal mine gas drainage system. Pipeline Fire Key Features: 1, flame arrester 13 consecutive times to subsonic flame test, every time blocked by flames. 2, hydrostatic testing 2.4MPa no leakage.
