Flame retardant - explosion-proof pipe flame arrester-Breathing valve flame arrester series-呼吸阀阻火器厂家-上海冠环阀门制造有限公司

Product overview

GZW-I,GYW-I type flame-proof - explosion-proof pipeline flame arrester, using a special fire retardant net with 3 to 13 mesh combination structure. Prevents 13 subsonic flame passes. Effectively ensure the safety of pipeline system. Widely used in: petrochemical, boiler, gas purification, coal mine gas emission and other occasions. In order to meet the requirements of different working conditions, our company produced this product is divided into flange pipe common type and welding high pressure pipe special type two. The main body can be made of cast steel or stainless steel 304, 316L material. It has the characteristics of reasonable structure, light weight, corrosion resistance, safe and reliable use, qualified explosion resistance, etc.

Main feature

Gzw-i type deflagration pipe arrester is a new type of combustible gas pipe arrester, which is a new product.

The flame arrester was tested jointly 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 conforms to the provisions of GB13347-92 "Fire arrester performance and test method for oil Gas pipeline flame arrester". The flame arrester structure is reasonable, and the fire retardant layer is made of stainless steel material, which is corrosion-resistant and easy to clean. The shell is made of stainless steel, carbon steel and cast steel, which can meet the needs of different process pipelines.

Main use

1, conveying flammable gas on the pipeline.

2. 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. 1. The flame arrester has been tested at subsonic speed for 13 consecutive times, which can prevent the flame from passing each time.

8, water pressure test 2.4MPa without leakage.
