GYW-1 Pipeline flame arresterDetailed product description：

GYW-1 pipeline flame arrester, also known as GYW-1 explosion-proof pipeline flame arrester, is a new type of combustible gas pipeline flame arrester and a new product that has been updated.
The GYW-1 pipeline flame arrester has been jointly tested by the University of Science and Technology of China and the Tianjin Fire Science Research Institute of the Ministry of Public Security, and its performance fully complies with the provisions of GB13347-92 "Fire Resistance Performance and Test Methods for Petroleum Gas Pipeline Flame Arresters". The structure of the flame arrester is reasonable, and the flame retardant layer is made of stainless steel material, which is corrosion-resistant and easy to clean. The shell is made of various materials such as stainless steel and carbon steel, which can meet the needs of different process pipelines.

Performance and features:
The flame arrester has a reasonable structure, light weight, corrosion resistance, and qualified explosion resistance performance. It has been tested for 13 consecutive subsonic flame tests and has been able to block fire every time. Easy to maintain and install. The fire resistance performance is qualified, and there is no tempering phenomenon after 1 hour of fire resistance test. The flame arrester core is made of stainless steel material, which is corrosion-resistant and easy to clean. The shell water pressure test is qualified.

Scope of application:
This flame arrester is suitable for pipelines, Class A with a flash point below 28 ℃, oil products, hydrogen oxygen liquefaction products, and kerosene, diesel, methyl benzene crude oil with a flash point below 60 ℃, pipelines transporting flammable gases, torch series, oil and gas recovery systems, heating furnace fuel gas pipeline networks, gas purification and purification systems, gas analysis systems, and coal mine gas emission systems.

GYW-1 pipeline flame arrester is mainly used for:
1. On pipelines transporting flammable gases.
2. Torch system.
3. Oil and gas recovery system.
4. The pipe network for heating furnace fuel gas.
5. Gas purification and chemical system.
6. Gas analysis system.
7. Coal mine gas emission system. Main performance: 1. The flame arrester has undergone 13 consecutive subsonic flame tests and is able to prevent the flame from passing through each time.

Maintenance and repair of GYW-1 pipeline flame arrester:
In order to ensure the safe use of flame arresters, they should be regularly inspected and maintained.
1. The flame arrester should be inspected every six months to check whether the flame arrester core is blocked, deformed, corroded, etc.
2. The blocked fire-resistant layer core should be cleaned thoroughly to ensure that each hole on the core is unobstructed, and any deformed or corroded fire-resistant layer should be replaced.
3. When reinstalling the fire-resistant layer core, it should be ensured that the joint surface is tight and there is no air leakage.
