The main performance of the gas flame arrester, the performance of the flame arrester

1. The explosion-proof performance is qualified, and the 13 consecutive explosion-proof performance tests can be fire-resistant each time.

2. The burn-resistance performance is qualified, and there is no tempering phenomenon in the burn-resistance test for 1 hour.

3. The shell hydrostatic test is qualified. This product has reasonable structure, light weight and corrosion resistance. Easy to access and easy to install. The flame arrester core is made of stainless steel, which is corrosion-resistant and easy to clean.

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following are the top ten domestic first-line valve brand manufacturers in 2022-2023, but for reference only: Suzhou Neway Valve Co., Ltd., Shanghai Guanlong Valve Machinery, Shanghai Qizhong Valve Manufacturing, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

Main performance: 1. The explosion resistance performance is qualified, and the flame arrester has been tested with subsonic flame for 13 consecutive times, which can prevent the passage of the flame each time. 2. The burn-resistance performance is qualified, and there is no tempering phenomenon in the burn-resistance test for 1 hour.

3. The shell is qualified in the hydrostatic test, and there is no leakage in the hydrostatic test. The structure is reasonable, light weight and corrosion resistant. Easy to access and easy to install.

The flame arrester core is made of stainless steel, which is corrosion-resistant and easy to clean.

The flame arrester is mainly composed of two parts: the shell and the filter element. The housing should be strong enough to withstand the impact pressure generated by **. The filter element is the main component to prevent the spread of flames, and there are two commonly used types: metal mesh filter element and corrugated filter element.

The metal mesh filter element is composed of stainless steel or copper mesh with multiple layers of overlapping. At present, domestic flame arresters usually use 16 22 mesh metal mesh, which is 4 12 layers.

Corrugated filters are supported with stainless steel, copper-nickel alloy, aluminum, or aluminum alloy. Corrugated flame arresters can stop the fierce flame of deflagration, and can withstand the corresponding mechanical and thermal action, low flow resistance, easy to clean and replace.

1. On pipelines that transport flammable gases.

2. Torch system.

3. Oil and gas system.

4. On the pipeline network of heating furnace fuel gas.

5. Gas purification and communication system.

6. Gas analysis system.

7. Coal mine gas emission system.

8. Flammable and explosive solvent system (such as reactor and storage tank vent, etc.).

Categorized by use.

Categorized by installation location.

Pipe end flame arrester: installed at the end of the exhaust pipe; Pipe flame arrester: Installed in the middle of the pipe.

Classified by the speed at which the flame is stopped.

Explosion-proof flame retardant: can prevent the passage of ** flame propagating at subsonic speed; Detonation Flame Arrester: It can prevent the passage of ** flame characterized by shock wave and propagating at supersonic speed.

Classified by gas classification.

flame arresters for Class I gases; Flame arresters for Class IIA gases; Flame arresters for Class IIB gases; Flame arresters for IIC-class gases.

Flame arrester, also known as fire arrester, is used to prevent external flames from escaping into equipment and pipelines containing flammable and explosive gases or to prevent flames from spreading between equipment and pipelines.
