Product Overview
 GZW-I, GYW-I-type flame retardant - flame arrester pipe explosion, the use of special fire-retardant network with a combination of 3 to 13 network structure. Prevents subthreshold flames from passing thirteen times. Effectively ensure the safety of pipeline system. Widely used: petrochemicals, boilers, gas purification, coal gas emissions and other occasions. In order to meet the requirements of different working conditions, our company manufactures this product into two types of common type for flange pipe and special type for welding high pressure pipe. The main body can be made of cast steel or stainless steel 304,316 L material. Has a reasonable structure, light weight, corrosion resistance, the use of safe and reliable, explosion-proof performance standards.


 Main features
GZW-Ⅰ-type explosion-proof flame-retardant pipe flame retardant system is a new combustible gas pipe flame arrester, is a replacement of new products.

The flame arrester by the China University of Science and Technology and Tianjin Institute of Fire Science Joint Test, its performance in full compliance with GB13347-92 "flame retardant gas pipelines and test methods" requirement. Flame arrester structure is reasonable, fire-retardant layer made of stainless steel, corrosion-resistant easy to clean. Stainless steel shell, carbon steel and cast steel a variety of materials to meet the needs of a variety of different process pipe. 
 
 Flame retardant - Flame retardant pipe explosion-proof main purposes
 1, the transport of combustible gas pipeline. 
 2, the torch system. 
 3, oil and gas recovery system.

 4, heating furnace fuel gas pipe network. 
 5, gas purification Tonghua system. 
 6, gas analysis system. 
 7, coal mine gas emission system. Main performance 1, flame arrester 13 times to subsonic flame test, each time to prevent the passage of the flame. 
 2, 2.4MPa pressure test without leakage.
