1. Main characteristics:
GYW type resistance deflagration type pipe flame arrester, is a new type of fuel gas pipe flame arrester. According to the test of the University of Science & Technology China and the Ministry of public security fire science Tianjin joint test, its performance can meet the requirements of GB13347-92 "oil gas pipeline and flame arrester test method", according to the pressure level can be divided into light pipe flame arrester (GYW-1 type) and heavy pipe flame arrester (GYW-2). Flame arrester reasonable structure, fire retardant plate made of stainless steel materials, corrosion resistance and easy cleaning. Shell made of stainless steel, carbon steel and cast steel materials, which can meet the needs of a variety of process piping. Explosion proof corrugated pipe flame arrester production, has the advantages of compact structure, high reliability, the fire retardant core parts, anti-corrosion, explosion-proof fire resistance performance is strong, easy cleaning and other advantages, is particularly suitable for hydrogen, nitrogen, oxygen, liquefied gas and other special medium. The main varieties: pipeline explosion-proof arrester, corrugated pipe heat vent pipe flame arrester, ZHQ, drawer type arrester, explosion-proof fire ventilation hood.

2. Main application:
1 The pipeline for delivery of combustible gas. 2 torch system. 3 oil vapour recovery system. 4. Pipe network of heating furnace fuel gas. 5. The gas purification system. 6 gas analysis system. 7 mine gas drainage system.

3. Main performances:
The fire resistance 13 times in a row to subsonic flame test and it can prevent flame through every time.
