First, GZW-1 explosion-proof pipe flame arrester Overview:
GZW-1 explosion- proof flame -type pipe flame arrester is a new combustible gas pipe flame arrester, is a replacement of new products.
The
flame arrester by the China University of Science and Tianjin Fire
Research Institute * * joint test, its performance in full compliance
with GB13347-92 "flame retardant gas pipelines and test methods," the
provisions. Flame arrester structure is reasonable, fire-retardant layer made of stainless steel, corrosion-resistant easy to clean. Shell with stainless steel, carbon steel and other materials to meet the needs of a variety of different process pipe.
Second, GZW-1 explosion-proof pipe flame arrester performance and features:
1,
the flame arrester structure is reasonable, light weight, corrosion
resistance, explosion-proof performance qualified for 13 times in a row
to subsonic flame test Fire.
2, easy maintenance, easy installation. Resistance to burning qualified, resistant to burning test 1 hour without tempering.
3, flame arrester core stainless steel, corrosion-resistant, easy to clean. Shell hydraulic test qualified.
Three, GZW-1 explosion-proof pipe flame arrester Scope of application:
The
flame arrester is suitable for pipes, flash point below 28 ℃ Class A,
oil, hydrogenated liquefied and flash point less than 60 ℃ kerosene,
diesel, a stupid Crude oil, flammable gas transmission pipeline, torch,
oil and gas recovery system, furnace fuel gas pipe network, gas
purification Tonghua system, gas analysis system, coal mine gas emission
system.
